Sex with My Sister (Book 5 Chapter 4)

... her right tit. “Awe, you’re telling me that you don’t want my big fat cock in your tight little pussy?” I asked as I moved my fingers from her clit, and traced them down to her opening. She didn’t argue as I went back to sucking on her neck and slowly moved her panties aside. She was enjoying the attention too much. I rubbed her outer lips for a moment, and dipped the tip of my index finger inside her. She was wet with anticipation. I slowly repositioned myself, and slid my cock in her tight snatch causing her to gasp. She looked down and watched as I began thrusting in and out of her pussy slowly. “Oh fuck.” She moaned. I raised my other arm to her baby doll top and lifted it up, freeing her tits, and then started massaging the one I hadn’t yet done. Her nipples were already hard. Yeah, my cock was still sore from yesterday, but I was just so turned on that I couldn’t help fucking her. She lifted her legs so they were bent on either side of me. “Cyrus. I need it harder. This is driving me nuts.” She said. “Please?” Not wanting to disappoint her, I began picking up some power and speed. She wrapped her legs around me as I continued fucking her. Her pussy was an inferno within a few moments of this, and began to squeeze my cock for all it’s worth. She reached down and began teasing her clit as I fucked her. “I’m… so… close…” She panted. I didn’t respond, I just kept sucking, groping and fucking. ...

... “Cyrus! I’m gonna cum!” She cried out. She did too, and I felt it gush out of her pussy on my balls. “Oh god.” She moaned as I gave a few more thrusts, then began cumming inside her. I pulled back from her, as I thrust hard again as I came, looking into her eyes, as they went wide. “Oh no. I forgot to put in more birth control this morning.” She said. “I thought you told me you weren’t worried about that.” I panted as my cock kept spasming inside her. “I wasn’t but we weren’t trying for a baby, and I’ve been ovulating since yesterday.” She said. This bit of news made my eyes go wide. No wonder she had been insatiable yesterday. Mom was probably in the same condition. That’s why she told me that nothing was a hundred percent, and it was still possible that they got knocked up. I laid down on my sister and kissed her neck. “So what? Like you said, we won’t care about what anyone thinks.” I told her. This made her wrap her arms around me and squeeze me tight. It was exactly what she had wanted to hear from me. “I should be ovulating for the next couple days if you wanna keep trying.” She whispered. My cock twitched inside her in response. I was getting very turned on by the thought of my twin sister getting knocked up with my kid. “I’ll take that as a yes.” She giggled and hugged me. I didn’t know it yet, but mom and Emma had planned out the entire trip for tomorrow, and planned to keep me from driving.
