Sleepover
At the start of last year, I found I was getting closer and closer to my gay friend Jack. We would sleep over, talk about girlfriends and sex, we would even compare naked pictures of ourselves on chatrooms.
A week before school started, he invited me over for a sleepover, and I hornily (unknown to him) obliged. When I went over, we did the usual things, such as played PS2, used his trampoline, and had a shower (not together).
That night, we were playing truth or dare, and as with all teenagers, it turned to being nude. I started it by saying 'Get naked.' He then did the same to me. Then we compared.
'Wow, yours is big!' He said to me. I was 14cm.
'Yeah, yours is ok too.' I said. He was pretty smal, despite being a year older.
We then wanked and it was the best in my life. We also tried other things, but that's for another time...
