When I was in the seventh grade (about 12 years old) I sometimes stayed with my friend Marvin (also a seventh grader) on overnights. We were very good friends and it didn't bother either of us that we had to share the same bed on these overnights.

On one of these nights we had gone to bed wearing just our little boy briefs. We weren't really sleepy and instead we started tickling each other. One thing led to another and soon we had our hands inside of each other's underpants, groping around and squeezing each other's little peckers.

Unfortunately, we were making a lot of noise and Marvin's stepdad came charging into the room and flipped on the light switch. I didn't think we were doing anything so bad, but Marvin's stepdad was quite upset, yelling things like, "I told you boys to go to bed and not to make any more noise. It's late and you need to be quiet."

Then, suddenly, without warning, he pulled Marvin right out of bed, put him across his lap, tugged his underpants down and spanked him. Right across his bare bottom. That was not the first spanking I had ever seen, but it was perhaps the first spanking that I witnessed that got me "excited!" Marvin had a really nice smooth chubby bottom that appeared to be perfect for spanking. As the spanking progressed, Marvin squirmed around and cried, and that made the spanking experience even a little more exciting for me.

When it was over, Marvin stood up and his stepdad left the room. He had turned around, not to show is little penis probably, but I got a great view of his very round and very red naked ass.

When he got back into bed, I rubbed his butt for him. And we were soon asleep.

A few days later we were at my house after school. We were tickling and wrestling on my bed when I suddenly began taking Marvin's pants off. He didn't seem to mind at all, which was very nice. And soon I had his pants off and had him over my lap giving him play spanks on his tight little briefs. As I spanked him, he laughed, but I was growing a nice bulge in my pants. This was perhaps the first time (although certainly not the last time) that I got a boner while spanking someone.
