A few years ago I stayed up very late stroking and finally had a huge load.  I headed upstairs to go to sleep as I was very tired (way past my bed time lol) and my cock was sore and shrunk down to almost nothing, like I had been swimming in cold water.  Anyway I lay down next to my sleeping wife and see a light coming through the curtains.  I decided to see what it was and when I looked through out bedroom window the light was coming from next door.  I looked down and my then neighbor was stroking to his computer.  I quick put on my glasses and there he was naked in his chair (my bedroom is on the second floor, the room he was in was on the first floor with tall windows).  

I watched his expression and looked over his body.  Not an attractive man but here he was less than 20 feet from me naked stroking away.  He had a hairy chest and an average sized cock like mine.  Without touching anything my shriveled up cock was now rock hard and throbbing.  I pushed my boxers down and started tostroke while watching him stroke.  My mouth started to water as I was so turend on by this.  I would have done anything for him at that moment.  I'm stoking my cock with one hand and pinching my nipples with the other and quickly popped another load.  This landed on the floor.  my worn out cock is strating to shrink, I have a load of cum on the floor all the while my wife is inocently sleeping during my whole bi curios event.  I quietly whipe up my cum and ease into bed again and try to sleep while my mind is racing.
