Last week I went over to my best friend Tina's house to hang out. The door was open so I went in and headed back to her room. As I walked by her twin brother Tim's room, I saw him naked on his bed jerking off! His eyes were closed, he was breathing fast, and his face all scrunched up, and he was rubbing up and down really fast. Within seconds his stuff shot out onto his stomach. I must of gasped or something, because he looked over at me then quickly covered himself with his shirt, and yelling SHIT SHIT SHIT! I really didnt know what to do, so I started to leave, and a couple seconds later he yelled out for me to wait. I said ok but waited by the door, because I was scared, and didn't want him to try anything on me. When he came out of his room he had his shorts on so I stopped being nervous, particularly because he was so nervous and embarrassed. He was saying he was sorry, and to please not ever tell his sister or anybody else. As he was talking, I noticed that his stomach was still slick from his stuff where he hadnt wiped up completely, and he had a pretty big bulge still in his shorts. I've always kind of had a crush on Tim, because he is really cute, but I wasnt really in his league of friends.
I told him I wouldnt tell anybody, but he had to let me see his dick again. He looked at me kinda funny and I explained I had never seen a grown one before, and to please let me see it again. He moved away fromt he doorway and pulled it out. It was softer than before, but still big, and I asked him if I could touch it. He let me and it felt really nice and warm. It started getting bigger as I held it, and real fast it was as hard as when he was jerking off. I started to pull on it, and he let me. He took my hand and told me to do it like this, so I did. We moved to the couch and he sprawled out, and I started jerking his dick again, after about five minutes he shot his stuff again, but not nearly like the first time, it sort of oozed out onto my hand. I wiped my hand on his stomach, just as Tina and her mom pulled into the driveway. Tim quickly zipped up and ran to his room. I turned on the TV and acted like I was just waiting for Tina when she came in. I was so psyched I had jerked off a boy! That night I made myself cum while reliving the episode in my mind, and I had an awesome orgasm. I really want to do it to him again, just figuring out how we can hook up!
