This happened last night... and I can't get it out of my mind.
Last night I was staying over at a friends house. He wasn't feeling well and went to bed early. I retired to the basement and watched a movie with two of the other guys staying the night. I dozed off part way through the movie, but awoke at the end when they took out the video, stopped it and went to sleep.
Earlier we had been talking about masturbation. Myself, 17, a friend 17, and then a friends younger brother 15. We were continuously teasing the 15 year old about masturbation and to keep his hands above the covers.
When the film ended and the lights went out, I could faintly make out the noise of the 15 year old boy masturbating. I wasn't sure if it was just my mind playing tricks on me, or if he actually was going at it no more than 3 feet from my head. I got up after 5 minutes, sporting a huge boner, which I didn't think would be noticed, I went and turned off the computer monitor so it would be perfectly dark. Then returning to my matress on the floor. I rolled around a little, finally ending up on my back with my cock out the fly of my boxers.
I slowly started to jerk off. Trying to keep as quiet as possible, not caring to alert the 15 year old, but I would be shamed for ever if the 17 year old, also only meters from me, heard what I was doing. Probably 10 minutes after I started, I shot what has got to be one of the biggest loads of my life. With cum drenching my sheets, and all over my chest, I am ready to settle down for sleep (I don't usually clean up, just shower in the morning).
That's not the end though. Now the 15 year old had listened to me jerk off, and I slowly started to hear him getting into the rythem again. He was less cautious this time, and I could hear several pairs of furious strokes. His breathing got heavy, and he started to pick up the pace. With in about 5 minutes of my ejaculation, this 15 year old boy had me fully hard again. I listened a little longer, then I rolled over, still drenched in cum, and started to work my meat for a second time.
This time showing even less caution, and making certain that if the 15 year old was awake, he was listening to me. I made deliberate loud heavy strokes, and didn't try to hide my breathing. This time took me only 3 minutes or so to get off and shoot a much smaller amout of cum on my belly again.
After that, my friends brother and I both being 'beat'. I packed it in for the night and went to sleep. In the morning we didn't say anything to one another about the nights avents, but I would have liked to know if he heard and enjoyed my show.
Also, I learned when I shoot the much cum, it's a good idea to clean up. when I lifted up the blanket in the morning it was damn rank!
