For a couple years, my older brother and I were in the same college. We rented out an apartment together near the campus. One day, I got home earlier than my brother expected, and I found him having sex with his girlfriend on the couch. I told them they could continue as I walked to my room. Not that it did much good for me as I could still hear them. My brother and his girlfriend came by to apologize which I didn't think was necessary. She was flattered when I told her what a nice rack she had.

She came by to see me later that night. According to my brother, he was willing to share his girlfriend with me. If she wanted to fuck me, she was allowed to do so. It was all private, so my brother wasn't idly watching it happen. Boy did we fuck so much. Usually, it was after my brother had sex. It only lasted a couple terms, but I could not be more thankful for my brother and his girlfriend.

The only difficult part about all of it was how much she loved teasing me. She would strip tease, rub my crotch, and do what ever she could to turn me the hell on. Then she would just leave me hanging to have sex with my brother, and she never came back to me. Those days drove me crazy.
