She slammed back down my dick.I fucked upward into her again. And again.Delight shone in her blue eyes as I bounced her on my cock. Squeals of girlish... pleasure burst from behind her hand. Her asshole clung to my dick. Her pussy clenched down on my aching shaft as she bucked up it. Her underage twat gripped me. Teased me. Pleased me. It was incredible to feel. My balls approached a boil.She slammed down me and bucked.Her pussy went wild around my dick.She squealed into her hand clamped over her. Losing all control I closed my eyes and let out a scream that Im sure my whole building heard, as I bucked my hips wildly. My pussy filling his mouth with my juices. Never before had I ever experience anything like that. My whole body shuddered in ecstasy. He loosens his grip on me letting my legs relax on the bed. I laid there motionless as he planted small kisses around my still twitching, dripping wet pussy. As he lifted his head I smiled as I watch my juices drip down his chin. He licked. I stopped as I began to get under the covers to remove my panties. They would just be in the way tonight.I did not aggressively just "do" myself that night. I remember laying there thinking about what my sex life with Bill might be.I know that straight intercourse was out. I had read about and knew too many girls who ended up pregnant using the "safe"methods of birth control. The day or two following the end of a period should be safe, and doing it during a period should be safe, but both of. A little while back, I was let out of school early and came home and I walked upstairs to my room. Before I opened the door, I heard moaning coming from our room. It sounded like my sister and she was saying something. I opened the door a little bit and there was my sister fully naked spread eagle masturbating. I was about to leave but then she moaned my name.“Oh Sophie yes please more more more!!!!”What was even crazier was that I was getting turned on by it and before I knew it my hand was.
