But us all being adopted we had formed a strangely strong bond of brotherhood.We were all lying in bed, with the TV on watching friends, I had my lapt...p open and was watching the video with the screen facing away from them. Mike turned to me, "Are you watching the video?"I tried to look confused "What video"Mike smiled "I know, the one of Katie"Jeremy butted in "Did she know she was being filmed, she is so hot"I said "C'mon man, that's my sister! I know its not the same for you-"Jeremy gave me. I would be his cum slut... his whore... whatever he wanted me to be.As I played "horsey", bouncing up and down on his lap, he met each downward push with an equally strong upward thrust, driving his cock deeper into me, impaling me on the solid shaft. Feeling his hard stiff cock sliding up and down my pussy walls was incredibly arousing and as hot as I was for him, I knew that it wouldn't be long before my orgasm hit.I was moaning and whipping my hair to and fro, completely enraptured with what. A rush of butterflies came into my stomach, and traveled down to my pussy leaving a tingling sensation. I was so wet just my seeing my brother and knowing he was thinking about me naked. I could also see the huge lump rising in his pants. I didn’t know what to say, but he could tell I was staring at his erect dick. “You ever felt a cock before?” “No, never. I’ve always wondered what one would feel like…” I trailed of, hoping to give my brother a hint. I wickedly reached down under my blanket. We were expected and ushered to a table at the back. There was a birthday party in, so I was glad to be away from them, I’ve been in those parties myself, and by the end of the night it can get a bit raucous. We got on well together, with a few mutual interests, wildlife, spectator sports, adventurous sex (hopeful anyway). Neither of us was very political. Chris said he shouldn’t really be on this training as he was the parts manager at a large franchised garage. He just filled the place as.
