Pah! Pah! Pah!
The heat building in his balls was almost unbearable.
He knew he wouldn't last much longer at this rate, but he didn't care.
All that mattered was the exquisite sensation of being buried deep inside Mira's welcoming body.
He continued delivering a series of loud, stinging slaps to her sensitive skin.
The sounds echoed through the room, each smack leaving a bright red mark on her pale flesh.
"Ah! Fuck!" Mira cried out, her body jolting with each blow. "You're going to leave marks, you bastard!"
He leaned into her, over her back, his groin hitting her ass faster and faster.
"That's right," he growled, his voice rough with lust. "I'm going to mark this ass as mine. You're going to remember who fucked you like this when you sit down in class tomorrow."
His hips moved faster and faster, driving into her with a ferocity that surprised even him.
"Mmmmmm."
Mira whimpered, her hips pushing back against him instinctively.
Pah! Pah! Pah!
"Ahhhh!"
"Ahhhh!"
"Ahhhh!!!"
Her unrestrained moans grow louder and more desperate with each passing second.
"Ahhhh!" she cried out, her fingers clutching at the sheets beneath them as she arched her back to meet his thrusts. "Yes! Right there! Don't stop!"
His hands groped her tits, squeezing them tightly and aggressively.
His index fingers pinched her nipples as his head nuzzled into her neck, using it as support.
The increased pace caused Mira to moan out louder and louder, her head whipping back.
"Ahhhh!" she screamed, her entire body convulsing as the waves of pleasure crashed over her. "I'm coming! I'm coming!"
She came again, shouting even louder.
At the same time, Elion grunted, plunging deep into her womb with a thrust.
He spilled his seed deep inside her, filling her up completely with his sticky, white cum.
Her belly felt hot from being filled to the brim.
He stayed on top of her, continuing to grope her tits in each hand as spurts of his cum rolled inside her.
"Cummmming!" Mira's voice was barely audible as she came, her body twitching from the intense orgasm as she took in all of Elion's thick, creamy cum for a creampie.
Her tongue stuck out, and her eyes rolled to the top of her head.
Elion got off of her, carefully taking his flaccid dick out of her twitching little sister.
The sleek white semen from his release spilled out of her insides.
"Oh shit," he realized, "I came inside of her in the heat of the moment. She was just too tight!" he thought.
He was worried that if she got pregnant from that, they would both be in trouble.
He shook his head, thinking that he would deal with it later.
For now, he admired the sight of Mira lying there limply, still twitching with her eyes rolled back, her ass cheeks crimson red, sweaty body, and twitching pussy spewing his cum.
"That felt so good," he said, but Mira was barely able to hear him as she basked in the afterglow of their intense session.
The sight made Elion's dick twitch back up into stiffness, ready for round two.
Elion smiled proudly at his own stamina, pleased with how his half-incubus body was performing.
"Are you ready for round two?" he asked, his voice laced with mischief.
Mira finally came to, her tired but satisfied eyes meeting his.
Her ass was still angled up as she looked back at him over her shoulder, with Elion's cum dripping out of her onto the sheets.
"W-We're not done?" she managed to say weakly, her voice shaking with shock.
She had grown accustomed to William's lackluster performance, never even fully penetrating her.
His small prick barely entered her, leaving her unsatisfied every time.
He's a monster, she thought, fear written across her face as she eyed Elion's already raring-to-go dick.
Before she could react, Elion grabbed her ass and positioned himself at her entrance once more.
He teased her wet, swollen labia with the head of his cock, but then his eyes shifted to another sweet spot.
Wait!?
A mischievous grin spread across his face as a lightbulb went off in his head.
He aimed for her other hole, not her pussy, but the tight-looking little asshole on top of her little sister.
When she felt where his tip was teasing, her eyes went wide with horror, "Oh no, you can't!" Mira squealed, trying to push him away.
But Elion was relentless, his cock twitched with anticipation as he prepared to claim her sister's virgin ass next.
"Not there! That's the wrong hole!" Mira screamed out, trying to wriggle free. "Please! It won't fit!"
But Elion was relentless, pushing the tip of his cock slowly into her ass, which was already well lubricated from being inside her vagina.
Mira found herself powerless against Elion's insatiable lust.
She could only tremble in fear, wondering what other depraved acts this monster would subject her to.
"Oh, relax," he said, "You'll be fine."
He pushed in slowly, grunting as he felt how incredibly tight it was. "Fuck," he exclaimed out loud, "It's even tighter than your pussy."
"Heeekh!"
Mira cried out as Elion sheathed himself into her unbelievably tight ass.
Her nails clutched the sheets tightly, in pain, unable to believe that she had lost her anal virginity.
But she could not deny the pleasure that was writhing through her, along with the pain of her asshole being stretched to the max.
It was a strange sensation, unlike anything she had ever experienced before.
She was terrified, but also curious, wondering what it would be like to have Elion's cock deep inside her in this way.
Elion groaned deeply as he slowly sank into Mira's tight asshole, feeling the walls clamp down around his throbbing cock.
The sensation was unlike anything he had ever experienced before, intense, almost overwhelming in its pleasure.
"Fuuuuck," he moaned, his hips twitching involuntarily as he fought the urge to start thrusting immediately. "You're so fucking tight, Mira. I can barely move."
Mira whimpered beneath him, her body tensing as she tried to adjust to the foreign intrusion.
It felt like she was being split open, stretched beyond her limits, and yet there was an undercurrent of pleasure beneath the pain that made her ache for more.
"Please..." she gasped out, her voice trembling. "Please go slow. It hurts."
