I'm in college and staying at my aunt and uncle's house. They have kids and their kids have a lot of friends that come over all the time. One day I was upstairs in my room watching TV and jerking off to porn on my computer. I never heard him yelling for someone, but he must have heard the TV because Clark, my cousin's 13 year old friend walked in. I tried to hid my dick but it was impossible, plus the porn was still going so he could hear the moans. At first I thought he was going to leave, but instead he asked, 'I've never seen another guy naked before'. So I moved my hands and looked at him. He's about 5'9', 115 lbs, blonde and athletic. It was VERY clear that he had a growing bulge in his basketball shorts, so I asked if he wanted to join. He said, 'sure'. He walked over to my bed and took off his shirt and pulled down his shorts to reveal a 5' uncut dick. He got in bed beside me and we jerked off together. We both came at the same time. Since we had cum on ourselves we decided to take a shower. We climbed in together and started washing. While lathering up his dick started growing again, he said 'I guess I'm not finished after all'. So I started to get hard again too. I said, 'Hey, do you wanna try something?'
'What?' he asked. I pulled out my vibrating razor, you know, the one's that are battery powered. Well I took the razor part off, put some liquid soap on it, turned it on so it started vibrating and slowly put it in my ass. I started jacking off and came in the shower. He looked shocked, but I told him to try it. He looked skeptical, but I 'lubed' up the razor and handed it to him. He took it and slowly moved it to his ass. I watched as he inserted it and his face squirmed a little. After a minute or so he relaxed and started smiling and said, 'This is awesome!' I laughed and he started jacking off. It took about two minutes but finally he came all over me and the wall of the shower. We both laughed and finished washing off. Now he comes over to see me as much as he does my cousin!
