Watching My Wife

around 20 years ago now, and I still have these visions in my head, it was one of the horniest things we ever did as a couple.
One Saturday night out in a town nearby, we went to a small nightclub that we used to frequent in our younger days.
we have been in this place about an hour, had a couple of dances together.
I had a bit of a thirst on so suggested I should go to the bar and get the drinks.
When I returned, Jane came over to me and told me the the guy in the white shirt, who incidentally we had laughed at earlier because of his extravagant moves, had approached her and asked her is she fancied a fuck.
She said my god, straight to the point, she had told him no as she was with her husband.
We have a good open marriage, so I asked why she turned him down, then called her a chicken, as she always says she would take any cock offered.
She said I'm not a chicken and downed her drink and went marching off to the dancefloor, almost immediately walking back past me with the guy with the white shirt.
I put my drink down and followed a a distance, out of the club and round the corner, where I saw them disappear up some steps, into a building, my heart sank as I thought my dare had backfired and and I wouldn't get to see any action.
I then noticed a Ladies sign, it was a public toilet block.
I looked around and all was quiet, I went up the stairs and entered the ladies toilets. there were about 8 cubicles and only one, at the very far end was shut.
Quickly but quietly I entered the one next door, locked the door and stood and listened, I could hear some light groaning from Jane but nothing more.
I put down the toilet seat and stood up on it, carefully looking over the top of the cubicle.
Jane was stood there, her white knickers pulled down and he had his head buried in her pussy.
Jane noticed me looking over, smiled, winked, then carried on.
The guy stood up, I moved away, then slowly looked over again, Jane had her back against the cubicle door, her knickers were on the floor and he had his hard cock in his hand trying to slide it in her, not working he turned her round and entered her from behind.
The sight of seeing your wife taking another guys cock is something else.
I was hard and had to release my own cock, he slid in and out of her, she was now groaning heavily and I knew what was coming next, sure enough she gushed, releasing a torrent of fluid all over his cock and their legs.
That was all I could take, I felt my cock start to pulsate and there was no going back, I pumped shot after shot of spunk down the wall.
He in turn was in the same state I saw him tense up then groan as he pumped his seed into my wife.
I quickly wiped up and left the cubicle, carefully entering the outside world so as not to be seen leaving the ladies toilets.
I waited just over the road, they both appeared together and walked towards the street corner, I could see they were in conversation, but Then Jane kissed him and turned to walk towards me, he disappeared into the night.
When she got to me she asked if I had enjoyed what I saw, I told her what I had done on the other side of the wall, she got o
hold of my hand pushing it between her legs, she told me he hadn't hit the wall with his, but emptied it inside her, she didn't have her knickers on so slipping a finger in, I could feel his cum.
We had to contain ourselves but ordered a taxi and 20 minutes later we were on the floor at home fucking again, to reclaim her.
