I felt like tonight's events were incomplete. Amber obviously wanted some release, she was definitely enjoying herself, but she didn't get to finish y...t. Hopefully that's what she was planning on doing in the privacy of her own room, but if I've learned anything tonight it's that privacy doesn't mean much in this house. I had to check and make sure she was taking care of herself right? I mean, she's my younger sister, it's my responsibility to make sure she's going to be ok! The excuses we tell. OMG she’s masturbating! I was both aroused and panicked. I sat there quietly, but my male hormones got the best of me and I soon found myself opening up the remote desktop application so I could see what she was looking at. She had one of the websites from earlier open and was uploading pics from her phone to it while browsing the site. My cock got so hard so fast; I am surprised it didn’t tear a hole in the leg of my shorts. Again I found myself in need of moving my manhood to relieve the. I began to push my cock in his mouth to and fro. Yes!!! I placed both my hands on his head and began fucking his throat. He was choking. I could hear that.The way Mark sucked my cock gave me feeling that he could go on and on. But I would not be able to hold my load of cum for long. I pulled it out, bent on him and sucked all the saliva he had on his mouth. I liked the taste of my dick. "Put your arms around my neck" I whispered. He did as I told him. I lifted him with his legs wrapping my ass.. "Take me out" he whispered. He was driving out of the gym grounds. He turned left, which is towards the woods and not on our way home. I stroked his cock. He was thick and the tip was glistening. I leaned across him and circled his tip with my tongue. He gasped as I did so. "Someone is horny" he said. I couldn't answer him as my mouth was filled with his cock. He pulled into the woods and turned the engine off. He lifted my head and told me to get out the car. We walked into the woods and he.
