This story reminded me of a similar experience so
long ago I had almost almost forgotten. Thanks for reminding me!
Private circle jerk
Many years ago we had borrowed an old fashioned make up dresser from a friend while they were moving which had three mirrors, two were folding side panels. One day after showering I was drying off while looking at myself in the mirrors and realized I could see three images so I decided to adjust the two side panels until I could see three images of me all at once.
My wife had already gone to work so I decided it would be exciting to beat off watching the mirror images so I could look down at myself and look up, right, left and center and see four hard dicks. I had never taken part in a circle jerk but the sight of four dicks gave me an intense urge to masturbate. When checking out all the images my dick became hard in only a few seconds and looked bigger than ever. I couldn't resist any longer and started to beat off.
I started off slow at first enjoying the sensation of something new to watch while I masturbated. Before I was too far along I reached for some tissues from the top of the dresser where my wife usually puts on her make up to catch my cum. I continued to watch the mirrors as I pumped my dick up and down for a few minutes. I couldn't decide which image to watch but I felt there were actually was four guys masturbating together. The new and unusual feeling was amazingly arousing as it was a different experience for me. I have always enjoyed the sight of my cum shooting off but had been too embarrassed to ever think of participating in a circle jerk.
As the sensation became stronger and stronger I started beating faster and my dick began to throb and pulsate until I couldn't hold back any longer and started shooting it seemed like more cum than ever before. The sensation and sight of cum shooting off from what looked like four dicks simultaneously was awesome.
I made sure my wife never caught me doing it as as she would have killed me but I repeated my private circle jerk several times until we unfortunately had to return the dresser. I've always wondered if anyone else used it the way I had.
