She was moaning from my licking. When she couldn't take it anymore, she begged for me to fuck her. She told me to be gentle as this was her first time.... Talk about being in luck, being able to take my sister's cherry. I positioned my cock at the entrance of her cunt, and slowly entered her. Man was she tight. She was even tighter than my previous girlfriends when i did them for the first time. I made my way inside her till i felt a barrier blocking me from entering. I held in there and ask her. I spread his cheeks with my hands and worked my tongue into his tight hole. He squirmed and pressed against me. I rolled my tongue tight and started darting it in.Dennis stood and turned, leaning over the chair. I pressed my face to his ass he pressed back and began to bounce on my tongue. I couldn’t take it anymore; I stood and wrapped my arm around his stomach sliding my hard dick up and down between his cheeks. Just as I started looking for the lube bottle on the dark floor he spun away from. Through the fog as my orgasm began to subside, I heard him say to Slim "Fuck her good, man, she's loving it." Slim replied " Yeah man, this pussy is amazing.I can feel her cumming." As he increased the speed and intensity of his thrusting, his balls slapped against my clit. I felt him swelling inside of me as he started moaning out "Oh man, I'm gonna cum too." Turning my face back toward him, I commanded "Put it in my mouth baby. I want to taste your cum."I could feel the walls of my cunt spasm. My heart began beating faster because I knew that I had been caught, but I just went along with it in hopes that I was wrong. I got a shirt for her and my boxers then walked over to her and set them on the couch. I did not know what to say or do so I just stood there. She asked me if I was even curious at all as to why she asked for a pair of my boxers, and all I could think of was "No, I've got a pretty good idea why."Instead of putting the rest of the clothes on she took my hand and walked me.
