Mami Tomoe. Elder sister, magical girl, lonely girl. Your next-door neighbour and soon to be babysitter.
You were a kid who lived next door to Mami Tomoe, and from afar you admired her greatly. More than that, you even crushed on her. Who could blame you, the fifteen-year-old was simply gorgeous. A soft gentle face that was often held in a warm motherly face, soft silky blonde locks she had in impressive twin-drills, and her body. Good lord her body. You were a kid who after discovering your father's porn stash had a very early yet very powerful sexual awakening, and Mami didn't help to keep your libido down, often being the subject of your frequent masturbation sessions.
Taller than you as she was a teen and you were a child, she swayed around with plump thighs clad in stockings, a nice plush rear, a curvy hourglass figure, and all topped up with two huge boobs that bulged through her school uniform. She was perfect, no porn star you secretly looked up on your laptop compared to her, buckets were lost.
One day your parents were out, as usual. They often spent their time away at work, leaving you to fend for yourself alone. Sadly, this was one of the rare times you forgot your keys, so when you got home you were left outside of your front door on the verge of tears, unsure of what to do. But fortunately, minutes after you were stuck there you heard a soft mature voice come from your side.
"Oh my, are you okay, is something wrong?". You turned around and your heart thumped. She looked like an angel there and then, with the setting sun casting a soft orange glow upon her. That gentle smile that had been turned into a look of concern only for you, as if in that moment only you meant anything to her, the trepidation in her words made you feel like you were all that existed in the world.
"I-I'm fi-... I'm not fine..." you said softly, still scared and sniffingly. You decided to be honest, to be a big boy and tell the truth asking for help.
Mami placed a hand upon her cheek, her expression growing even more concerned as she walked over to fret upon you. "Oh goodness me, what's wrong boy?". She stood before you now, before slowly crouching down. Then placing a hand of reassurance upon your shoulder and squeezing gently. In that moment your tears began to dry up, you felt safe with her. You still sniffled a bit, until Mami said "Now now, big boys don't cry. Calm down and tell me what's wrong, I can help. What's your name?" she asked.
After a moment of shyness on your part you mumbled your name out, fidgeting. The sight of a cute little boy so nervous instantly awoke Mami's maternal instincts, and she said in a gentle coo "What a lovely name. I'm Mami, Mami Tomoe. So, what's wrong?"
After a moment you confessed. "I'm... locked out of my apartment. I forgot the keys, and my parents are working late. And I... I...".
Mami began to stroke your hair, gentle shushing you into a serenity, saying "There there, I'm here for you. How about you wait in my apartment? You can have some cake I made, and I'd appreciate the company. You seem like a good boy." she said.
You nodded eagerly, partially because you truly did feel scared locked out of your apartment, but mostly for a chance to be alone with the crush you jerked your cock off to many times. She gave you a smile that flooded you with warmth, like she was sunshine that only you basked in. You felt your cheeks grown red, and your eyes glued to her with awe. She extended her hand to you, which you eagerly took. It was a bit larger than yours, and oh so soft and warm. It felt heavenly, her hand clasping yours. Curiously she had a ring upon her finger, a pattern painted onto the nail of that finger. It was peculiar to you, but you hadn't thought more of that beyond fashion.
Little did you know how important that was to her and would be to the nature of your relationship that would soon bloom.
Squeezing your hand she slowly stood up and tugged you into her apartment just next door, guiding you into the safety and warmth of her domicile. When the door clicked shut behind the both of you took off your shoes and coat, instantly feeling the relief of her heated home that warmed you from the biting cold outside.
"Please, make yourself at home-" she gestured to the plush couch in the living room "-would you like some tea and cake? The cake I had made myself, it's quite delicious~" she said with a playful lilt to her voice, accompanied by a wink of her sparkling golden orbs.
You nodded once more profusely, your mouther watering at the offered treats. Your blatant desire for sweets made Mami giggle, a hand to her chin as she regarded you warmly. "I see, then sit tight and I shall prepare the sweets.", and she disappeared into the kitchen. Or what of the kitchen there was, being a part of the living room. The apartments were rather open; her kitchen only being isolated by a counter that she diligently worked on. You watched her keenly prepare the tea, steam wafting out of the spout of a rather decorative pot she used, matching cups and saucers for the delicious drink. Then from the fridge she procured a large cake, already sliced. White and frosted with fresh red strawberries placed upon it, which she scooped two slices of onto two plates. All of which sat neatly upon a trey she carried to the coffee table, setting it down with expert grace. It only made her seem more perfect in your eyes.
Placing the teacups which sat upon pristine saucers in front of you and the spot she would join you on, she poured out a generous measure of a delicious smelling brown liquid that began to fill the elegant cups. A gentle clink of porcelain upon glass sounded when she placed the sweet treat and warm tea down in front of the two of you, and she sat herself down on the couch beside you. This close you could smell the sweet perfume of her that masked a wonderful aroma of natural body sweat, the two mingling to create an intoxicating scent that captured your attention, desperate for another whiff.
"By all means, eat up. I hope it's to your liking~" Mami said, taking up her own slice of cake and eating a modest amount at a time with her fork, her movements smooth and graceful.
You picked up your own slice, gripping the plate in your small hand. You went to scoop a large chunk of the cake first but grew bashful at the sly look she gave you. Feeling embarrassed you opted to cut a smaller chunk at first to scoop up with your fork, eliciting a giggle from her at your behaviour. "It's okay, eat as much as you want~" she said gently. You took her up on that the moment the cake hit your tongue, it was so sweet and moist, a perfect cake slice that melted on your tongue in sugary bliss. You couldn't hold yourself back from scooping more into your mouth, licking your lips with delight and popping the strawberry in, letting out a satisfied hum of satisfaction at the delicious treat your crush had blessed you with. You washed it down then with sips of the equally as wonderful tea.
"Oh my, it seems you must have been rather hungry. Or at least my cake was just that good? I'm flattered someone enjoyed my baking that much~" Mami said with warmth, gratitude in her tones at your appreciation for her home-made sweets.
The two of you then continued to drink the tea, filling the cups when either of you so wished, whilst engaging in pleasant small talk. The two of you learned much from each other, hobbies and interests, friend and families, hopes and dreams. It felt so natural talking to each other, with no desire to really hold anything back from both of you. Your heart ached when Mami told you of the tragic death of her parents, how it left her essentially alone. She skirted how she miraculously survived, but you didn't dwell on what she was suddenly hiding from you, too saddened by the poor curveball life had suddenly thrown at her and that she now had to live with. What you said next brought pause to her.
"It's okay Mami, you're not alone now, I'm here!" you chirped joyfully. To you the words were partially innocent, your sexual desires only partially worming into your sincere statement. You truly wanted to be there to keep her company, so she wouldn't be alone anymore. The fact that she was the crush you spent many nights spanking it to was just an added bonus.
But what you saw in her eyes made your heart soar, because you saw the same thing in her eyes. Those golden orbs were wide with surprise and longing, mouth hanging in a small 'O' of surprise. A tender pink dusted those soft white round cheeks and were you in direct contact you would certainly feel the flutter of her heart. Your declaration to be there for her had really struck a chord, and soon after a loving smile spread across those delicate lips, eyes sparkling with a joy you hadn't quite seen there before.
"Thank you... That... that means a lot to me. You're quite the little charmer aren't you, for such a young boy to say something as pleasant sounding as that." she placed a hand upon her cheek, giving you a warm look, "Are you sure you can keep a promise like that, boy?". And you nodded profusely, eager to prove yourself. She would not be alone anymore, and you'd make sure of that.
...
The two of you remained like that in a comfortable atmosphere, making small talk until the sun had set and you receive frantic calls from your parents who must have come home to an empty apartment. Guilt gnawed at you, but the ever kind Mami held your hand and lead you outside, her knuckles gently rapping against the door to your home. Your parents instantly answered it, relief washing over them. They were furious at first but settled down when you explained to them that you foolishly forgot to grab your key, but also the kindly Mami Tomoe watched over you whilst you waited for them to return.
It took only a minute for your parents to think up of a plan, knowing that if they couldn't be there for you for the precious few hours they still worked, then the kindly next door middle schooler (who seemed incredibly responsible based on her mature and refined disposition) could babysit their kid. Mami seemed enthusiastic at the idea, and at first refused payment but ultimately relented, the fat stacks of cash your folks offering swaying her even more. It was a great deal all around, Mami got to enjoy the company of a charming little boy, you got to spend more time with your crush, and Mami would receive some extra pocket change from your parents, who could rest easy knowing their kid wouldn't be alone anymore.
You were starting to look forwards now to the few hours after school.
...
With another day at Mitakihara elementary ending peacefully, you headed out of the gate and made a short walk over to the nearby middle school, where you waited outside for Mami to come. You got a few looks of confusion from the boys and adoration from the passing girls, the ladies fawning as they passed you by at how cute you were. You paid them no mind though, only one girl was the object of your desires. And soon she came, walking out of the school where she was talking pleasantly with some other girls you didn't recognise, a small pinkette holding the hand of a boy, a taller bluette, and a raven haired girl who to your surprise had a swollen belly that you recognised as being late pregnancy. Your sexually awakened mind recognised pregnancy when you saw it, but the exact workings of how it happened were still a mystery, you just knew that when your white pee went into a pretty lady, she had a baby after a while.
When she spotted you, her smile widened just that little bit more, and she bid her farewells to her friends once she got to you. Smiling warmly as she said "Well then, shall we get going. I bet you're hungry, what would you like for dinner?", and the two of you walked home together.
When you got there she got to work cooking a delicious meal that you helped her to make, something which made her happy, giving you a warm smile whilst she hummed gently in a comfortable silence whilst the two of you worked together. Then after a delicious meal you two shared in the dimming sun and cleaning up after yourselves, you both sat on her couch. She turned to you with a kind look, saying "Well, now that you're fed, how about we take a look at that homework of yours.". Homework was usually something you dreaded, but basking in the maternal warmth of Mami Tomoe, homework didn't seem that daunting.
You got out the sheet of mathematics, laying it down on the coffee table. Mami tugged the table closer to make it easier to see, and then did something that made your heart hammer in your chest. She scooted closer, her thigh pressed against yours, shoulder to shoulder. Then tucking some strands of hair behind her ear in a motion that was far more seductive than she likely intended, she leaned in next to you. You stiffened as you felt the huge softness of her chest press against your arm, but what truly made you melt was her gentle canter once she spoke to you. In a hushed whisper that sent tingles through your body she spoke to you, going through each question with you that you could barely focus on with her gentle words tickling your ear.
Soon enough it became too much, especially when your scattered mind finally managed to finish the paper, and in a soft serenade she said, "You did it, good boy~". That broke you, your twitching phallus that struggled to stay down suddenly received a flood of blood, your premature hormones rearing to life. "Hm? Are you okay, you've gotten so... uh... stiff..." Mami said, trailing off as her eyes wandered down from your face to your crotch. Out of embarrassment you tried to cover the tent you were pitching with your hands, but your shaft was just too big, and it strained painfully against your pants and already began to leak precum that seeped through the fabric to darken the peak of your boner.
Mami gasped at the sight, a hand to her mouth. Her eyes widened in surprise, a blush going to her cheeks at the sight of your might, and as well as that she felt something else... something warmer within her, something stirring inside at the sight of such a large boner bulging against the cotton confines of your pants. "Oh... oh my..." she gasped in a hushed whisper.
You gave her an apologetic look, yet that faded away soon as your eyes drifted down to her plush chest that still pressed against your arm, your thighs squirming against each other whilst you struggled to not grab your cock and furiously pump it. Mami watched all of this with a conflicted look, a fist to her mouth. She looked aside, finally peeling her gaze from your boner, a myriad of confusion and thoughts bouncing around her mind at this new situation she had been thrown in. What was she to do? What could she do? Well, there was one obvious solution, one forbidden... downright illegal... solution... yet her biological programming was making her want to submit to your impressive cock.
Mami bit her lip, and with a pensive look cupped your cheek and tilted your head so your eyes met. "I'm sorry, this is my fault you're like this, I was careless, wasn't I? I... will take responsibility, it's okay..." and she gave you a warm maternal smile that made your heart flutter, and your cock swell bigger. You knew what she was going to do now, and you thanked whatever god was watching over you that your dreams would come true.
She wrapped an arm around your shoulder to pull you in more to her embrace, the back of your head now nestling against the intoxicating softness of her chest. It was like a pillow from heaven that you had sunk into, and you let out a gentle sigh of content at the embrace, which drew a smile of satisfaction from Mami. The hand that was wrapped around your shoulder moved down to gently rub your upper arm, and her other hand wrapped around to splay across your chest, rubbing sensuous circles on your chest before slowly dragging down until her hand slid up to slowly wrap around your throbbing boner that screamed to be free of its clothe confines. Then in one swift motion her hand zipped your pants down and unhooked the button of the underwear below, making your cock spring out in its full throbbing glory.
Mami's breath was caught at what was laid bare, the cock seeming so much more daunting now that it was fully free. Mami would not be deterred though, she was responsible for bringing a kid to this level of arousal, and so she would help relieve your suffering with this painful looking erection. "My, you're quite large aren't you." and you twitched at her words of praise, making her giggle. Mami leaned down a bit, her hot breath ghosting your ear, "Oh, that made you happy, didn't it? You like it when I say how big you are? You're rather large indeed... long... thick... hard... ... and hooooot~..." she moaned her words needily into your ear, finishing her words with a delightful giggle. Then she wrapped her hand as best she could around your penis and began to jerk you off.
"shh shh, be a good boy now for big sis, okay?" Mami said, her soft hand gliding up and down your cock with surprising ease, the skin of your manhood being dragged along with her grip, all the little nerve endings lighting up with pleasure from the sensation. This was infinitely better than doing it with your own hand, hers was just so soft and lithe, like a silk wrap that was trying to coax an orgasm from you. "Do you like that?" she asked, and you could only manage a whimper from your embrace against her plush chest.
"I'm glad, but what if I did... this...?" she cooed before pumping faster now. Quicker and quicker her hand went, before suddenly stopping. Then Mami took long slow strokes all the way down to your base, twisting her grip along the way, before quickly hammering down on your cock again. She would repeat this, delicious beads of salty pre-cum practically fountaining out of your cock as you realised she was edging you, and painfully so at that. You let out a needy whine as she continued to tease your shaft, pump, twist, hammer. All in the same repetitive motions. Then when her hand had travelled up to the tip, she placed a thumb upon your head right over the slit, applying a gentle bit of pressure to the opening of your urethra that made you whine and squirm in her grasp. She rubbed circles onto the very tip of your cock, smearing your own juices whilst she kept twist her grip as if to wring the cum from your shaft. Your mind was beginning to melt from the sensations, being edged like this, an orgasm just brewing below the surface, yet Mami wouldn't let you have the release you begged for.
"Is it getting too much baby boy? Do you want big sis to let you finish?" Mami purred, releasing your cock only to send goosebumps down your entire body when she lightly scratched her nails slowly, sensuously, down the underside of your shaft all the way to the base before ending with a tender caress around the soft roundness of your youthful balls. You managed to peel yourself away from the soft confines of her chest to look up at her, and your heart skipped a beat. Despite how much she had been teasing and edging you, toying with your cock to prolong the praecipes of release you walked upon, she still gazed at you with the same almost maternal warmth and love as she had always. You nodded, pleading to cum.
Mami was more than happy to give you what you wanted.
She released her hold on you, letting you sit up with your cock pointing firm in the air. Then she pulled up over her head her school cardigan, and you bit your lip with anticipation a layer of clothing was removed, her chest closer to being free. With a sly look seeing your gaze so intensely fixated on her chest, Mami placed her hands onto the swell of her breasts, the sound of her shirt rustling as she rubbed her hands up and down the massive mounds before giving them a sensuous squeeze, her eyes never leaving yours as she smirked. Then sliding her hands back up her chest to her collar she began to undo the buttons of her uniform blouse, one button painstakingly at a time. She bit her lip with anticipation at your drooling gaze, fixated solely onto her hands that gradually freed her bosom from their cotton confines. More and more her cleavage was exposed, so large were they that the more Mami undid her shirt, the more they looked like they were threatening to spill out. With all the buttons of her shirt undone, she discarded it over the back of the couch.
Mami sat there, arms crossed under her chest to push them up, making them look even bigger. They looked huge, soft, and doughy. You were already somewhat familiar with the softness and scent of them, but that was through two articles of clothing, now apart from the yellow lacey floral bra she wore her heaving chest was so close. Your heart stopped for a moment when you saw Mami reach behind her to unclasp her bra, but then she stopped with a mischievous glint. "Sorry, but you're not quite ready for that yet. But I have a fun way to finish you off." Mami said with a wink, and your cock twitched with the anticipation of what she'll do now that she's shirtless.
You wouldn't wait long to see what Mami had planned for you.
Lifting her right arm up, she grabbed you with her left and yanked you towards her, rotating you. Then she pulled your face up into the crevices of her right armpit and brought her arm down to hold your head firmly into the sweaty creases of her underarm, your face now squished between her soft swollen breasts, her equally as soft arm, and your facial features crammed against a concentrated depot of sister stink. Though whilst you thought of it as sister stink, it was far from it. Her stink was rather pleasant smelling, the rumours that girls couldn't be smelly proven true. Your nose was assaulted by a sweet scent of body odour that was... strong. It didn't smell particularly bad, just smelled strongly, and it was mixed together with a subtle perfume that had the distinct yet subdued aroma of ___. The two scents both opposites and not coalesced to make one pleasantly pungent smell that made your head swim with lust.
You were left like that, head and body bent backwards, face smothered into Mami's armpit. Your body laid across her lap, with your cock stranding firm straight up. Then, whilst Mami had your brain being rendered into mush from her stink, her other hand gripped your cock firmly. And then she began to jackhammer. She was pistoning your cock, a tight grip mashing your phallus, long tight strokes going from the very base to the tip of your penis. "You gonna cum now? Go ahead, be a good boy for big sis and cum~ cum~! Squirt it all out, there's a good boy, squirt all that lovely kiddie cum whilst you smell my stink.~" Mami said crudely, though her words were muffled to you due to the place your head was trapped in. Even if you couldn't hear her though, her intentions were still conveyed from how she practically pulverised your crotch with her gripped fist. She wanted you to cum right away now, and you'd comply in just a moment longer. No way could you resist anymore, her softness, her smell, the love she looked at you with, her technique of wringing an orgasm from your abused cock. And of course, the fact that this was all from the woman you loved...
You couldn't stop it even if you wanted to.
With a muffled cry from the depths of her pit, you thrusted your hips up straight into the air, and you came harder than you ever had in your entire life so far. Masturbation truly paled in comparison to sex, especially when it was with your crush. Your cock throbbed and pulsed in Mami's grip, swelling with the thick sticky ropes that you shot out with the tightening and churning of your balls. Mami never let up on her rapid pumping of your cock, but when your seed erupted out of the slit of your mighty girthy cock Mami's eyes widened, pupils shrinking with hears blossoming in them, biting her bottom lip to the point where she almost made it bleed. Your seed flew high much to Mami's awe, squirting feet up into the air and splattering fat sticky ropes onto her couch, her floor, even splattering into the valley of her chest. Your ejaculated seed had practically redecorated her living room with the fruits of your love making. But whilst this thick fog of pleasure seemed to drag on for an eternity, it ended too soon.
Mami lifted her arm up and swiftly cradled your head as you went limp in her embrace, your cock starting to soften and shrink in her grasp with she immediately released. Shuffling your small preteen body she let you rest your head on her lap, and with her free right hand gently patted your head, her fingers running through your matted hair which clung to your face from the combined sweat of your own exertions and her steamy armpits your face had inhabited just recently.
After a moments respite clarity soon came to you, and whilst exhausted, you were certainly lucid. Your gaze, lidded and tired, locked onto Mami who beamed down from you above, nipples poking through her bra like sore thumbs. If you weren't so tired, what she did next might have made your cock instantly spring to life, but alas the small stamina of a kid meant that even the erotic display of Mami slowly licking the thick coating of cum you left on her hand, one finger at a time, couldn't bring your lust back to full bearing. But it was still a captivating sight, watching her run her pink tongue slowly up the length of each digit before sealing those tender lips around the finger and slowly sucking down to the knuckle. She repeated this for each digit of her hand, and by the end her mouth was full of your thick sticky jelly like cum.
She held her maw open, showing the copious amounts of jizz she scooped off of her hand, before closing her mouth, swishing the seed around like mouth wash. Then she made a display of swallowing your seed, her multiple gulps audible. Finally, she looked down at you, letting her mouth open with a satisfied "Pwah~" before smiling at you lovingly. Though those narrowed eyes so small that they were almost closed told of less than wholesome feelings behind that maternal smile.
"You did so good, boy. Big sis is very proud of you. That cum was so thick, I swear it very well was about to get stuck in my throat. And goodness, look at how far you shot your sperm. I am very impressed. Are you feeling better now, has big sis cured your pain?" she said, and when you weakly nodded, she giggled with delight before helping you to sit up.
"And you did your homework too, what a good boy. Now let's get you cleaned up before your parents come to collect you... It goes without saying that this is now our little secret, buuuut..." she turned to you with a knowing smirk, finger to her lips in a shushing gesture "I don't think you're in any rush to tell anyone of our little triste here.~".
As the two of you got to work cleaning up the proof of your passion, Mami said one last thing that cemented hope within your heart. She said, "Oh, if you ever feel a pain like that again... just come to big sis, and I'll make the pain go away, okay, kid~?"
...
Your relationship continued on in secret like that. Every day in fact. Like clockwork you would walk back with her to her apartment, the two of you cooking together, eating, making delightful small talk whilst doing your homework, and then once the two of you were done she would jerk you off. Sometimes slowly, sometimes quickly, sometimes she'd stuff you face first into her soft cleavage, other times she'd stuff you into her armpits again like she had before. Either way your life had now been filled with the pleasurable touch of the girl you were crushing on.
It was after one such jerk off session that Mami, who was typically satisfied with just licking up the remnants of your seed from her hand, wanted to do more. She wasn't satisfied with just licking, she made it clear she wanted to drink from the tap so to speak as she got up off of the couch, and with a soft hand on your knee to silently tell you to stay put, she got down on her knees before you smiling warmly up. You knew instantly what she was going to do, and your cock very quickly throbbed against your pants with anticipation. Her lips looked so soft and plush, and you trembled in place with the thought of what she was about to do to you.
"Something caught your interest, little brother?" She said with a teasing lilt to her voice, a dainty finger upon her plush lips. She looked at you, batting her eyelids with a seductive gaze of lidded eyes, her other hand resting atop her ample breasts that strained against the fabric of her uniform. The finger trailed down her lips, then her mouth opened and with her tongue lulling out she ran her finger down the length of her tongue. Along the way she scooped up beads of saliva on her fingertip, which with a giggle she smeared onto the straining tip of your shaft, further wetting the fabric of your pants.
"Since you've done so well lately, and have been such a good boy, I figured I'd grant you an even greater reward. You always said you enjoyed how soft and ample my chest was? Well, how about this..." Mami said.
You had seen her do it many times before, a quick toss of her sweater off, the bow around her collar, and then the slow sensuous popping of button after button as she undid her shirt. She looked up at you with a sultry gaze, peeling her shirt off agonizingly slowly, then tossing it aside with her other articles of clothing. She was left in a state all too familiar with you by now, that was until her slender arms reached up behind her and deftly undid the clasps of her bra. Your heart was hammering with anticipation, her breasts usually so firmly compressed and restrained by that elegant floral yellow lace were now sagging just the tiniest hint as freedom was soon upon them. Mami slid her arms out of the bra but hadn't allowed it to fall away yet instead crossing an arm over her chest to keep the goods covered for just a little bit longer, teasing you with that sly smirk. She knew what you wanted, and she was going to build up the anticipation for it, make you beg at the tip for her.
Then in one smooth motion she released her hold on the bra and allowed it to drop free, clattering onto the floor softly. With that, her breasts were exposed in their full magnificence. They were large. Very large. They had a natural shape to them, smooth mountains of creamy flesh that hung from her chest not quite saggy but not too firm, it was clear that gravity had a lot to pull down but her fertile youthful body was keeping them taught and in shape. At the tips of each massive mammary was a hard pink nub of a nipple, a sight you practically drooled over yourself for with the desire to latch on and suckle, some innate juvenile desire to seek out a source of nourishment. And this cow before you could provide a lot of that.
"Do you like them, boy?" Mami said gently, her hands dwarfed as she reached from underneath to cup them, jiggling the mountains of flesh in her palms before running her hands up to the tips and squeezing, her tits easily giving way and moulding around her firm grasp. She moaned needily, working herself into a state of further arousal as she played with her own breasts before you, those succulent boobs only seeming more and more soft with every squeeze.
"Watch this now...~" she said with a playful giggle before lifting one of her breasts up. No... there's no way... yet she did. Mami managed to bring one of her tits up right to her face, bending her neck down a bit she darted her pink tongue out to swirl it around the nub of her nipple. Your jaw was grazing the floor at this point, precum soaking through your pants at this erotic display of self-pleasuring. It only grew needier when she brought her other boob up too, clasping both nipples into her mouth tightly and sucking on them, a throaty moan resonating from deep inside of her all the while. Her eyes rolled back momentarily whilst she made such lecherous slurping noises before she let go, a wet pop accompanying the act, then a meaty slap of flesh on flesh when her tits dropped back down again.
"I can tell that had quite the effect on you, little brother... now, how about I let you get a feel of your big sister's chest? Try not to cum too soon~" she teased with a soft titter that made your balls ache and your heart melt.
Mami reached up and grabbed your pants and underwear in a single motion and tugged them off, leaving your bottom half entirely exposed. It still made you nervous, showing off this side of you to Mami, but she assured you every time that she was more than impressed with what you had and what you gave her. Like a big boy you mustered your courage to remove your hands from your penis, Mami giving you a proud look that you didn't need to be coaxed anymore to let her see your full throbbing manhood. "It looks like it's aching a lot. Fortunately, big sis has just what you need..." Mami said.
Then lifting up her large heaving breasts she spread them apart, and with a force that made you double over she clapped each sizable boob around either side of your cock. Lord was it soft, like being sandwiched between two firm marshmallows, and so big where they that even your large cock had been swallowed up entirely by her chest. Not even the tip poked out. Your features were slack sitting there, eyes lazily locking onto hers, the sensation of her tits for now only sandwiching your cock being overwhelming. Never had you experienced such softness before.
As if reading your mind, Mami smirked and said "It gets better, little brother..." then she took a moment to swish her cheeks around, clearly building up a great deal of saliva in her mouth, and after a moment she separated her chest from your cock enough to spit a huge glob of spit onto your cock head. The crude act and sudden warm fluids made your cock twitch needily, seeing the angelic woman you admired so much doing something so filthy? Then with a wet slap her breasts slammed back against your cock, and with agonizingly slow motions she worked her breasts up and around, twisting them about your cock to work her saliva around your shaft and coating her chest.
Once she was satisfied that your cock was properly lubed up, with a sly grin, she squeezed her breasts together tight around your throbbing fuck stick and began to jerk you off with her tits. Immediately you let out a long moan, sweat slicking your body and your cheeks aflame with the mind-numbing tit job she was giving you. You squirmed in place at the nerve rending sensation of her massive round globes slickly sliding up and down, your chest rising and falling releasing soft boyish pants in time with the action.
"Does this feel good?" she smirked, alternating her strokes with her chest, left then right, right then left. It was if your entire cock was being smothered in a surprisingly hot slippery blanket, crushed between her mountain of a chest in an effort to squeeze the seed from your smooth youthful balls. You gripped the couch cushions with white knuckles, eyes rolling back and core tight as you desperately tried to hold back an orgasm once again. But Mami wasn't having any of it, saying "No need to hold back, how about you just be a good boy, and cum... NOW!"
And with a great deal of force Mami crushed your cock between her breasts by wrapping her arms around her chest, this final pressure broke the dam, and doubling over you let out a cry as your cock throbbed and blew a huge load within the soft creamy crevice of her breasts, your seed bursting with such force that it even managed to breach between her boobs, a few small squirts flying up and splattering against her chest and neckline. Mami let out a gentle sound of awe at your impressive cumshot, "That was quite something. Did my chest feel that good?" she asked.
Weakly you nodded, exhausted but satisfied. "Good boy, now let's get you cleaned up… but first…" Mami said, releasing her grasp on her breasts and allowing them to flop free, your softening cock stickily sliding out. She got up from her knees, and then grabbing each boob she spread them apart, showing off the vast quantity of seed you have left behind, her chest thoroughly painted in boy cum. "My my, you really seemed to enjoy big sister's chest." She giggled. Then Mami reached down and scooped up a big glob of your cum from her chest into her palm, and bringing it up to her face looked directly into your eyes as she ran her tongue slowly over her palm to lap up every bit of seed you had left behind.
Your cock throbbed with need, quickly hardening again. Mami's eyes narrowed with lust.
"Good boy~" she purred…
…
Mami was late, she was late, and you were panicked. You had let yourself into her apartment after waiting outside the school gates for a moment, alone as none of her friends were around. As was usual you prepared a meal that was to your credit rather delicious, your culinary skills having improved rather drastically thanks to the nights spent with Mami. You had served a portion for yourself, and one for her that sat on the side of her attached kitchen. And you quietly ate by yourself, trying to keep the feelings of fear from taking your heart.
What if something happened to Mami, what if she was hurt, or attacked, or even worse? You bit your lip after finishing the final bite, anxious over the disappearance of Mami Tomoe. It was then that after you had finished eating and were cleaning away bowls and utensils that there was a soft click at the door, the lock shifting with the turn of a key and the front door swinging open. In stepped Mami, late at night, and looking exhausted.
And… in a strange costume.
Well, perhaps not strange. Naturally, you thought it suited her amazingly, that it was the cutest, adorable, fashionable, and erotic thing she had ever worn.
It was reminiscent of her school uniform, a short skirt that was yellow now, a poofy shirt with an elaborately laced corset strapped snug around her waist, detached sleeves went down her arms to fingerless gloves, a big yellow ribbon hung snug at her collar sitting neatly on her chest that strained against the fabric of her shirt, and to top it all off sitting on top of her head was the cutest hat you had seen with a large tuft of white fur flaring out. She looked radiant, the outfit simple yet dignified, dependable even. In fact, she even looked well… magical…
Mami stopped when she entered the kitchen proper, now registering your existence, and guilt overcame her features. She sighed heavily, unable to meet your gaze, saying "Right… I forgot…". For a moment, your tears had been held back in place of awe at her outfit and concern for the state she was in.
"Is… that for me?" she asked, pointing at the bowl on the side. You nodded, offering to heat it back up for her. Mami's breath stalled in her throat before she choked back a sob, tears welling in her eyes as she grabbed you and held you close to her in a tight embrace, her being shaking as she let out wells of pent up emotions. You didn't know what to do at first beside cry with her, but you settled instead to bite back your own sadness and cling on tight to reassure her, after all you had little to be sad about now that Mami was here. But you were certainly concerned.
It took a good while for Mami to eventually settle down, but once she had with a small weak smile, she reheated the food and sat down with you. "It's quite good" she praised.
"… I suppose I owe you an explanation. Your parents had- no. I put you under my care myself, and I left you alone like this…" Mami began, apprehension in her voice. You sat there patiently, a reassuring hand on her arm. She was grateful of the gesture, and continued with "You see, I'm… a magical girl…".
Over the next few minutes, Mami regaled you with her life's story, the tragic loss of her parents and a strange white creature who offered her a chance at life again after a fatal car crash if she pledged to protect everyone. Then the flood gates spilled open, and Mami told you it all. How lonely she had been, how she longed for company, that her magical girl duties made her keep an arms distance from everyone no matter how popular she was. It was breaking her.
Mami then told you how foolish she had been on a hunt today. It was supposed to be quick and easy, but her newfound friendship had gone to her head so to speak, and she very nearly made a mistake that to your horror she admitted would have costed her life. You very nearly broke down to tears yourself at the idea of Mami being killed by some abstract monster, but you held it back when Mami said this.
"It was the thought of you that made me keep myself in check. I felt invincible, for that moment I felt as if I could do anything because I wasn't alone anymore. But I remembered you and forced myself to be tempered. Because if something happened to me, you would be alone too… the thought of you being left alone like that, the same fate I had been suffering… it's what kept me from doing something irrational. So thank you, little brother…" Mami said with heart melting tenderness, true love and gratification in her eyes as she fully saw you for what you were, a part of her life that was impossible to be rid of, you were essential to her.
You both embraced on the couch together, the adrenaline from Mami's near death encounter starting to wear off, and she suddenly felt heavy on top of you. Not that you particularly minded her bearing down on you more, the weight of her softness pressed upon you was a delightful sensation. But it did have a side effect too on your young body, a twitch and a throb. You began to blush, now feeling very aware of her body meshing against yours, of the thick scent of sweat on her body, and you pitched a tent.
Mami instantly felt your sizeable mast bulge out and press against her belly button, her eyes widening with surprise before settling into a sultry smirk of arousal, saying "Oh it's like that is it? Here we were having such a heartfelt moment. I underestimated my little brothers… libido… I suppose as your big sister, no not just that, your magical girl big sister-" her smirk widened as she saw how awestruck and excited you grew knowing that she was a magical girl. All this time you had been fucking a magical girl. "-I should take care of your big problem again. How about this time though…"
Mami disconnected from your embrace, sitting back a bit, and grabbed the edges of her skirt to lift it up. Her own face began to flush, yet that sultry lidded gaze she held you with didn't betray any hesitance. Your eyes finally managed to peel away from her own yellow orbs and gradually trailed down.
Her cheeks soft and round were a deep crimson now, those plush pink lips you yearned to taste, eyes going further you saw heaving mammaries that were slightly damp around the edges with sweat, her nipples poking through like sore thumbs. Further down your eyes finally landed upon Mami Tomoe's most sacred area, her pussy. Black lace panties damp with arousal were clinging tightly around the form of her womanhood, making an erotically prominent cameltoe that bulged through thin fabric of her undergarments. She wasn't just going to make you cum with some light sexual play…
Mami Tomoe wanted to fuck you now.
And you were more than happy to give it to her.
"Shall we…?" Mami purred. In an instance you jumped up and threw you clothes off, eager to get to fucking right now. Mami giggled at your enthusiasm, finding it positively endearing, though her laughter did die down to some low chuckles at your throbbing manhood bobbing with every twitch. "Now, isn't that a sight for sore eyes…" she said.
Deftly Mami began to only partially undress, kicking her boots off, rolling her panties down, and unbuttoning her blouse to let her breasts hang free. "I figured you wouldn't want me to get fully naked, and that you'd rather fuck a magical girl in her own costume." She said with a low gaze. You nodded, face red to the tips of your ears. A magical girl, someone who fought for justice and protected people with their powers. And you were going to defile one with your huge preteen cock. It was a dream come true.
Mami reached under the coffee table and pulled out a jar of lubricant, adjusting herself on the couch so she was leaning back into it and both her feet were up with her so her legs were bowed in an M shape, and then unscrewing the jar lid she tipped the lube and poured the cold liquid from the tip down toy our base, making sure your cock was thoroughly sticky and ready.
"Come here boy, make love to your big sister~" Mami invited you with a purr.
She didn't have to say another word, kneeling on the couch with your legs spready, your thick cock bobbed and thrusting forwards with impatience you slammed the full length into her pussy. Mami threw her head back and let out a silent scream through gritted teeth. She ended up yanking you towards her with her arms wrapped around you tight, her chest heaving in your face. You didn't notice the blood that trickled around your cock from her broken virginity, your mind too numb from the velvety soft gorilla grip her pussy had around your cock and your face smothered between her huge sweaty pillows.
After a moment she pushed you back a bit so you two could look at each other. Her face was flushed with sweat, and she wore a frown that soon melted into fondness. "I get you're eager, little brother, but be a little gentler with me. I'm a lady after all~" she scolded you lightly, and after a sheepish apology and a ruffle of your hair, she gave you a nod to continue. "Now, I'm good and ready, so by all means little brother… fuck your big sister…".
So, you threw your hips back and began to pound her. Immediately the room resounded with wet slaps, your smooth balls slapping against her ass with the vigorous motions of your manhood splitting her flower open and digging into the velvety soft depths of her pussy. It was tight, impossible tight. If you thought the grip of her hands or her titjob were tight, it was nothing in the face of her virginal pussy. You groaned gently, baring your teeth with every hump you gave, the sensations of every bump and ridge of her pussy gripping and stroking your sensitive penis, lighting up your nerves with bliss, it was growing too much.
You called out her name with each thrust, fucking with wild abandonment, your premature hormones flaring with this dogged desire to breed the woman you loved dearly. And it was clear by her legs locking around your waist that she wanted this too just as badly as you did, her gentle hands intertwining into your fluffy locks, stroking your hair whilst she cooed to you. "There's a good boy… don't hold back now… keep fucking big sis… I love you…~". That last one made you tense up, staring at her with a pleading look. Did she really…?
Seeing your hesitance, Mami nodded with that maternal warmth you had come to adore, returning the feelings you held for her all this time. "Yes, I have grown not only to see you as my little brother, but to love you as well. Did you think I would let you into my flower like this with such reckless abandon if I didn't love you so?". You teared up for a moment, touched and overjoyed that Mami shared your love, so you declared your love to her with the full passion you held for this woman.
Then before the blushing Mami could say another word you crashed your lips against hers, a palm on each breast which you kneaded like dough. Her eyes fluttered shut, and with your lips locked you two began to share an enthusiastic make out. It was the first kiss you shared in this manner, something feral and lustful, a locking of lips driven by a desire to reproduce and seek the pleasure that came with.
You both moaned needily into each other's mouths, intense exhales of hot breath from your noses, your lust to grind your lips together overruling your need to breath, forcing you both to puff out quick intense bursts of breath from your noses.
Soon though Mami's eyes rolled back as you pulled a particularly intense manoeuvre, ramming your tongue deep as you could you swirled it around hers, drool seeping out from the broken seams of your liplock. As you swirled your tongue around you gyrated your hips with every thrust, matching the swirling of your tongues with your cock stirring her pussy up. All the while your hands were gripping her breasts intensely, fingers sinking into the soft pillowy mounds that threatened to swallow your digits entirely.
Eventually the two of you broke the kiss, breathing heavily, your steaming breaths mingling with each other in the tiny gap between your lips. Your eyes bored into each other's lovingly, pure carnal desire and deep swells of adoration burning in your eyes. Hearts were practically blooming in Mami's eyes, there was but one thing she needed right now, one thing she was begging for.
"Cum inside of me!" she pleaded in all but a whisper. And you happily complied.
Mami locked her legs tight around your waist, and in an effort to blow the biggest load you could muster you proceeded to pound into her pussy, slamming your hips with such force that the couch you both sat upon began to scrap across the floor with each thrust, rocking with the motions of your love making. Your lungs burnt with the exertion of howling in pleasure; throaty cries of bliss bounced off her once quiet and empty apartment that was now filled with an orchestra of love making regularly. It quickly grew to be too much, and before you knew it your orgasm was here, and it hit with full force.
"Yes! Cum for me little brother, come on baby cum, cum, cum! That's it, oh that's it! YES! MMM-YES!" Mami cried out as you gave a few last shallow thrusts, and your cock bulged with thick gooey blasts of semen deep into her womb, the bumpy ridges of her pussy stroking each shot of seed as her pussy squeezed like a velvety vice. You felt your crotch quickly grow soaked when Mami's legs locked around you trembled with the release of her own orgasm, her feminine juices flooding the couch below with each quivering squirt of her pussy. Both of you cried out in the throws of pleasure, though Mami tried to hold hers back into a deep moan when she bit her bottom lip, eyes crossing momentarily in a display that was ironically more erotic than just howling with her orgasm.
Neither of you were sure how long your orgasms lasted for, but you presumed a while, because before you knew it your vision was going white with the almost painful exertion of cumming truly buckets into the womb of the love of your life. But as quickly as it came, it went just as fast, and you soon collapsed on top of Mami whose own legs gave out and slumped down the couch. Your cock softened and slipped out of her pussy, which trembled and quivered with fat globs of cum oozing out.
You were both a mess, hair matted, bodies absolutely soaked in sweat, yours a glistening sheen on your young naked preteen body and Mami's magical girl outfit absolutely soaked through. God, she smelled wonderful in the aftermath of brutal breeding sex.
Despite how messy and exhausted you two were though, you couldn't be happier. Looking up at Mami, she shared the same blissful look of content that you did, and in that moment you both shared a quick yet adoring kiss with each other. Yes, neither of you were alone anymore, finally you found each other.
…
Of course after such passionate and messy sex, especially unprotected, pregnancy was a natural conclusion. Soon Mami's belly swelled with the fruits of your love making, and naturally you kept this a secret from your parents, Mami playing it off as a now broken up with boyfriend who did this. Your parents initially didn't approve of such an irresponsible girl now taking care of you, but you were so (innocently in their eyes) smitten with her that they couldn't bear to keep you from Mami, she was just too good for you. Oh, if only they knew the truth. The results of this now was Mami getting paid a bit extra, which allowed her to live more comfortably and treat you more often.
It was another chilly afternoon, the orange sun burning low, that you both found each other once again in her apartment. The moment you stepped in conditioning made your cock harden and throb, and Mami's pussy soak through her panties. If anything, that fat swollen baby bump Mami now carried made her even hornier, so she sat down upon the couch and beckoned you with one sultry finger, saying with a smirk.
"Well little brother, your big sister is waiting…"
And you then pounced on her.
Mami Tomoe, your babysitter, big sister, magical girl, and girlfriend
