Finally Her Little Sister

Jack finally fucks his girlfriend’s sister. But was it worth it?

Kitty was standing in her door when I came out of the bathroom and she smiled at me and waved me towards her room. She was wearing a tee shirt that just barely covered her ass and nothing else. I walked to her, unsure of what she wanted, and just as unsure as to what I might do.

“Hi Jack,” she whispered as I approached her.

“Hey, Kitty. What’s up?” I tried to sound casual, like I hadn’t just been watching a video of my girlfriend’s baby sister masturbating.

“I heard you guys fucking,” she said.

“I’m sorry. I hope we didn’t bother you.”

“I heard you call her Kitty.” Her voice was small, and she looked up at me with big eyes and a tiny smile.

“We were just playing a game…”

“It’s okay,” she said, interrupting me. “I want to fuck you too.”

I stared at her in shock, but she leaned forward and I could smell her perfume and her hair. It was dizzying. She stood on her tiptoes and whispered in my ear.

“If you tear this shirt off me and throw me down on the bed, I’ll let you fuck me as hard as you like.”

“Kitty, I’m not sure it’s a good idea.” I looked over my shoulder at the door to Jane’s room.

“The only thing,” she said, kissing my cheek, “is that you have to make me do it. I’m going to beg you to stop, and I want you to fuck me anyway. No matter what I say.”

I was harder than I had been in weeks, and everything Jane and I had done suddenly felt stupid and insane. We were playing a game, and while it was fun, this was the real thing. Kitty was offering me everything I wanted, and all I had to do was take it. She tugged on the collar of her shirt, and I realized there was a small tear around the neckline.

“Tear it off my body,” she said again, this time looking down at the floor. She looked up after a few moments and her eyes were open and she looked afraid. “If you want me, that is.”

I was on her a second later, and her shirt came off with one hand. I tore it open, pushed her back into the room and closed the door behind me. She fell back onto the bed, and her tiny body was even more perfect than in the video. Her cunt was smooth, and her chest rose and fell as I moved to her without pause.

“Please don’t,” she said, her knees coming together in an attempt to push me away. I forced her legs open, my hands grabbing her wrists and pushing them down onto the bed. With my shoulders I forced open her thighs and buried my mouth on her cunt. She squirmed and writhed, trying to push me away, all the while saying no over and over again just loud enough for me to hear.

The harder she struggled the tighter I held her, and her pussy was perfect. I wanted to drown in her and never let go. I wanted to taste her for the rest of my life, and I was perfectly happy for it to end as long as I was with her. I pushed my tongue inside her, and opened her with fingers. I caressed her thighs and wrapped my hands around her ass pulling her to me. She continued to push me away, but I didn’t let her go.

“Please,” she whispered again. “I won’t tell anyone, just don’t fuck me.”

That was enough for me, and I opened my jeans with one hand as I moved up her body before crushing her lips with my own. I kissed her neck and her chin. I sucked her tongue into my mouth, pressed my knee between her legs, and tasted every inch of skin I could manage. I kissed her breasts and her shoulders, and when I felt her bare skin against my cock I almost came.

When I finally entered her, she was pounding her fists on my back and biting my shoulder. She whispered stop over and over again as I fucked her, and I was in heaven. Her cunt was impossibly tight, and I couldn’t have stopped if I wanted to. I crushed her body, held her arms firmly above her head, and kissed her mouth as I slid in and out of her. She tried to continue her protests, but my lips wouldn’t let her, and the faster I fucked her the more she struggled against me.

“Harder,” she whispered so quietly I almost didn’t hear her. I slapped her across the face, leaving a warm red mark on her cheek before thrusting even deeper. I lifted a leg up against her chest and took her faster and faster, my hand coming down on her body with far less strength than I had ever used on Jane.

I turned her over after a while, and slid back inside her as she tried to climb away from me. I pulled her back onto my cock, watching as her lips opened around me, amazed at how she could fit me at all. Her small hips pushed back against me, and with one hand in her hair, I pounded her cunt until I knew there was no going back. I turned her over again, this time staring at her body as I slid inside her, and she knew it was almost over.

“Please Jack,” she moaned. “Please don’t come inside me.”

I came instantly. I held her by her tiny hips, and thrust as deeply inside her as I could, wanting to fill her with more than just my cum. I wanted to fill her with everything I had: my blood, my bile, and every ounce of desire within me. When I finally collapsed on top of her I wasn’t sure if I could ever get up. She was crying and still trying to push me off her, but I kissed her tears and wouldn’t let her up.

“You have to go back to Jane’s room before she wakes up,” she whispered. “Please don’t get me in trouble.”

I stared at her for a moment before sitting up on the bed. I grabbed my shirt and my pants, but didn’t bother to put anything on. Their mother was downstairs, and Jane was surely still passed out on her bed. Without a word I opened the door, walked into the hallway, and shut it behind me.
