It was so soft there, between the pillows of his ass, so slippery and inviting. Then I dipped my tongue into him. His whole body tensed up. It was so ...mazing, that control I had over him. I wiggled my tongue to deepen the penetration. It had never been in such a soft place before. I started licking him harder, as if I was sucking for honey. And then came the unexpected. When I looked up, his cock was fully and beautifully erect. Right in front of my face. What a cock. Definitely number one on. Helen didn't stop it, she was happily being treated rough. She enjoyed her brother taking control.It wasn't long before I felt myself about to cum. "Im cumming," I whispered.Helen really went for it and I felt my cum shoot straight into my sisters mouth. She swallowed it without complaint and then sucked the head, milking me for any more cum. She finished and crawled back up me and gave me a kiss, I could taste myself a little bit, but I was so horny I wasn't bothered.I pushed Helen onto the. Long, straight brunette hair that whipped around as she danced with abandon. Her breasts weren’t large, which is probably just as well. The way she was throwing her body around her halter dress probably couldn’t have contained them if they were any bigger. Her short skirt flared out as she danced; sometimes if she tossed her hips just right, we could see the ass cheeks not covered by her thong.As she headed toward her table when her last partner pooped out, Wallace approached her and led her. “You’re a dirty slut, you know that, Kait?” He said breathlessly. “I’m your dirty slut,” I said enjoying the fucking he was giving me. “You’ve been so bad, Santa is going to put coal in your stocking,” he added. “As long as I have your cock in my cunt, I don’t care!” He let out a small laugh before thrusting me harder. It was starting to hurt, but damn it was a good hurt. He began slapping my ass as he fucked me with more intensity. It was all that I could handle, but I wasn’t going to scream.
