Anne entered the bathroom and sat on the toilet, breathing heavily as the sight of Natasha sucking her brother's dick flashed through her mind and the look her brother gave her. Was one filled with lust, making her pussy throb as she shook her head. "No, you can't, that's wrong, don't think like that, Anne." She said.
The bathroom door opened, and I walked in, fast, closing it before locking the door. "Orion, what are you doing!" She said, shocked as I walked over.
"It's not nice to spy on people. What will happen if I tell Mom that you did it? She would be so disappointed in you." My words made Anne shiver as I walked closer, making her back up until her back was against the wall.
"But I wouldn't do that to a sister I love so much," I whispered into her ear, sliding my hand around her and squeezing her ass. This shocked her as she was about to speak. I kissed her, forcing my tongue into her mouth. This act took her aback, as I slowly pulled up the bottom of her dress.
Anne tried to push me away, but found she couldn't do so, pushing my thigh between her legs, making it rub up against her pussy. She moaned as we kissed. I felt her body quiver as her underwear got wetter. Anne was already pretty turned on from watching the two of us.
My hand squeezed her ass cheek as her dress was pulled up to her hips, already allowing me to sink my fingers into her flesh. She moaned louder as my tongue played with hers. Anne slowly started to play with mine in return, telling me her walls were starting to crack.
I slid my hand into her panties, making my way to her clit as I spread open her legs with my leg. The moment my fingers touched the already exposed clit made her wrap her arms around me, shaking as I rubbed it faster, feeling her pussy gush out.
Pulling on the back of my shirt as her hips started to move, wanting me to play with it more, I slowly pulled my mouth away from hers and started to kiss her neck. "Oh my god! Orion, you are making me feel so fucking good." She moaned out. Her telling me this was a go-ahead to do more, as I slowly lifted her dress off her until she lifted her arms and helped me take it off.
"Take your bra off, Anne," I whispered into her ear, and she nodded, reaching behind her and unclasping her bra, letting her tits out. I started to kiss down her neck, making my way to her collarbone and sucking on it as she moaned out.
"God, I love this Orion." She said as I moved down her breast towards her nipple, as I played with her clit. Not letting her rest, I clamped my mouth around her pink, hard nipple, sucking on it before biting it lightly.
"Oh, fuck! I am going to cum! My brother is making me cum with his hand!" She yelled out, forgetting that people were here, as she squirts out inside her panties. Her body shook and quivered as I slowly pulled my hand out, showing her before bringing it to my mouth and licking her love juice off, making her moan out as I turned her around, pinning her chest to the wall.
"I am going to fuck you, Anne. And you are going to love it, your horny sister." I said, pulling her panties down and pulling my pants out, letting my dick fall onto her ass crack as she looked over her shoulder and spoke.
"It's so fucking big, it's bigger than any I have seen." She said, biting her lower lip as I whispered into her ear.
"Don't worry, I am going to fuck you from now on. No other man will be allowed to have a taste of my sister's body. Only I can." I said while pulling her ass cheeks apart and seeing her dripping wet cunt gasping for a cock.
Letting my cock drag down her ass crack until it reached her pussy and the head pushed inside her wet entrance, spreading her open. "Oh fuck, me!" She yelled out as I went deeper and deeper inside her.
"You white dick is so fucking big!" She yelled out as I got it all the way inside her, feeling her tighten around my dick as I poked the entrance to her womb, making her grit her teeth as she looked at me like I was a beast, but it wasn't hate in her eyes. No, it was complete and utter lust for me, her brother.
"You are a beast, Orion! Fucking your sister with this weapon!" She yelled out, losing any restraint as I started to move my hips, thrusting into Anne as her tits pushed up harder against the wall as she moaned.
"Yes, pound my pussy with that godly cock! You beast!" She yelled, but a smile spread across her face as she began to pant from the pleasure her moans echoed within the bathroom.
I slapped her ass, making her moan as she looked over her shoulder. "You monster, slapping your sister's ass as you pound her pussy into a hot, wet mess! Mother failed raising you, demon of lust!" She moaned out, but her face and body didn't match her words as she was loving every second of my fucking her sweet pussy.
"I am going to fill you with this beast's thick, hot load of cum. Pushing it into your womb, sister. Who knows if you will get pregnant with your brother's child?" I said into her ear as I moved faster, making her pussy gush out as my words brought her closer to her climax.
"Do it, you beast! Breed your sister, you already put that cock inside me. So it doesn't matter anymore, once I got a taste of this pleasure, you sank your fangs into my heart and soul! So cum, pump me full of your hot load!" She yelled out, not caring anymore, as I thrust deep into her one last time and release my load.
Anne sprayed the wall with her pussy juice as she climaxed, shaking and quivering as her eyes rolled into the back of her head, and her legs started to give out as I held her. Helping her to the floor as I slowly pulled out of her and turned her head, pushing my dick into her open mouth.
Making her eyes open as she looked up, seeing me smile as I moved my dick deeper into her mouth. Anne placed her hands on my thighs and started to suck on them, making sure to get what was left out. I pulled out slowly as she made a popping sound and smiled.
"Making your sister suck on your cum covered cock, what changed since we left?" She said panting until her body started to shake, and she spoke. "Something's not right!" She yelled out as I opened a portal and brought her inside, my sex world.
She was about to change and awaken her mutation.
