Many years ago with a friend
When I was a youngster my close friend and I learned to masturbate together. One afternoon he was over and we were taking about it and how often or how many times a day we usually did it. Well, it didn't take long for him to say thinking about beating off had him hard.
I said I was too and asked if he liked to watch himself in a mirror when he beat off. He said he did so I said, 'Let's go in the bathroom and we can watch each other in our full length one'.
We went in and dropped our pants and shorts and started in slowly beating thinking how good it would feel when we finally had a girl give us a hand job. In a few minutes our dicks were super hard and throbbing but we kept hold back to build up a big load.
When he said he was ready to shot his cum I told him to let's back up a bit unless we want to have to clean the mirror. Neither of us had cum in a few days so when we did cum was shooting off 6-7 times in gushes and we squeezed out the last few drops.
Lucky we didn't hit the mirror but we had a good bit of cum to clean off the tile floor.
It has been many years since then but sometimes when I masturbate I still reminisce about watching us shooting off together.
