I waited. All I could hear was shuffling and . . . a moan? What? I don’t know what made me do it but I opened the doorAnd there I saw my brother, bu...t naked on his bed with a guy! This was the last thing I wanted to see . . . especially my brother doing it! He looked up at me, so did the other bloke . . ."Damien! You know you can knock you fuck head!" he yelled at me. I couldn’t quite see the other guys face because he was covering it with the blanket, thank god. . I wouldn’t want to see his.

He loved the attention, and if I had a dick as big as his, I wouldn’t hesitate to show it off as well. He reached into his pants to adjust his balls and then pulled them back up. I loved our relationship. He took his big brother duty very seriously and never left me in the dark about any questions I could possibly have about girls, sex, or puberty. He was an open book to me. It was “us against the world”.“So you got a girlfriend yet? Got lucky?”“Not yet – I find a couple girls cute but I don’t.
