Jerking in the Hot tub
I was at my friends 18th birthday and it was a very cold night. Naturally, me and my friends, mostly guys and two girls, decided to get into the hot tob outside. The only rule was that everyone had to be naked. While nothing really happened for the two hours everyone was in the tub, things started to heat up as soon as almost everyone left.
A friend of mine, out of no where had just started fucking this girl in the hot tub, RIGHT next to me. I couldn't believe it. They went at it for almost 30 minutes. My other friend and I were sitting on opposite sides of the two having sex. For a while I felt awkward and I didn't know what to do. I didn't know whether to get out of the hot tub, or just pretend i was asleep. I stuck with the latter for a while. But soon, the friends who were fucking began to lean up against me, as they were to busy thinking of themselves.
The motions of their bodies began to turn me on. Within about a minute I had an erection. I didn't know what to do now. There was no way I could just get out of the hot tub. So began to jerk off. I'm pretty sure that the two who were fucking probably noticed, but that made it that much more fun. Soon I began to cum. It was the most amazing orgasm i've had in a while!
Meanwhile my friend on the other side still pretended to be asleep. I noticed that he also appeared to be jerking off just under the water. That hot tob was just filled with semen by the end of the night!
