Pissed On My Buddy's Wife

One off my best friends i've known since our teens. He lived nearby, we went to the same school and still live not to far from each other. We saw each other struggle with girls, talked about the first relations and the first sex. We went on several holidays together and still do. He got some kids, a year later so did I, so our lives pretty much had the same things going on.
Only difference, i got divorced, he is still married.

In our 20's he, his gf, me and my gf went camping outside a few times.
tents next to each other, at night drinking, laughing, campfire etc, hope you can imagine.
My gf and i were pretty messed up for sex, having threesomes, her sucking my dick in most weird places and all. And piss sex. She loved to drink from my dick, pissed on in the woods.
But, with them around, that was harder to do.
One last night with a lot of booze, warm outside, i felt some urge to go pee. my gf already hinting she was willing to walk along and i was getting horny by the thought of it.
My buddy stood up, said he had to piss and walked to a tree. She looked at him, smiled
and said she wouldnt stay up to long as she wanted to fuck him in the tent.
We laughed, and said she'd better get in the tent to get ready.
gf and i started kissing, feeling each other up, knowing that we soon had the place to our selves.
Buddy came back, asked where his gf was and we pointed to his tent. He smiled and went in.
Within moments there were soft moans and i really got horny, feeling my gf up and down.
She moved between my legs, pulled my shorts and started to slowly suck my dick.
The feeling of needing to go, hearing them fuck and getting sucked was awesome,
it didnttake long before i filled her mouth as i heard a loud moan from the tent.
gf cleaned me up and asked to give her the golden.. i smiled, just here?
i stood up, she moved in, and just as i started to release, i saw his gf silently coming from their tent. She stood there, watched.. i tried to stop, but couldnt anymore.
She just stood there as i pissed on my gf, who licked, drank and let it get all over her.
i was both hot and embarrassed.
Dont know how long she might have watched, but then she left to the woods (prob to pee herself). When i was done, i told my gf what happend, she could only laugh.
We cleaned up, went in to the tent. Next morning his gf didnt mention it (thank god), we cleaned up and left.

So, i got divorced and some months after that they invited me over to talk. They wanted to be a few days without their kids and wondering if i would go along camping. 2 tents, he laughed.
I was in for that, so we arranged al stuff.

We had quite some fun, again lots of drinking and talking at night.
The last evening he walked up to the trees, she smiled and said she never forgot what she saw. I asked her what she meant (i really forgot about all of it) and she told me about catching
me pissing al over my ex.
i blushed, sorry, it wasnt meant for you to see.
She said it was ok, that it was actually hot to see it in real.
I looked at her...
Apparently she had some nasty ideas, but some he said no.
She said she would like to be pissed on, drink it, see what it would be like, and if i could help her, cause he thought that was way to nasty.
I was shocked to hear her say that. How.. when.. where?
She clearly had thought it over... she would fuck him in the tent and he would be asleep in seconds. Then she would get out, pretending to go pee herself.
The thought of doing that, to her, i was instant hard and she smiled, dont go to far, as she stood up and went inside their tent.
He came back, i smiled and pointed to the tent. He smiled, gave a thumbs up and quickly i heard soft moans again. I rubbed my hard dick and drank one more, got some towerls and thinking wtf would this run in to. Can i really do this..... I was about to stop, get into my tent, when i heard a hard moan. They were done.
Not a minute later she came out of the tent, her tits free and only panty and shoes on.
I looked at her, horny and she took my hand.
We walked a few trees away from the tents and i asked if it was ok.. she smiled and got on her knees.. take it out. i took it out, but being hard i knew i wasnt able to pee and told her.
She smiled, need some help? and slowly took it i her mouth, as her hands starting jerking me.
i pinched myself, was this really happening? my best friends gf sucking me, about to let me piss on her?
i said im cumming, she pulled me out and let me come on her titties.
as soon as i was done cumming, i felt some other urge. I looked at her, sure?
she nodded, pushed up her tits, and i let go... A hard stream ran over her tits, with her hands running thru my flow. then she took my dick in her hand, moved it to her face.
pissing on her cheeks.. then in her mouth... She was so hot doing that....
slowly i ran out... her with a big smile... man that was hot, you are dirty, she said.
I quickly realized.. he can never know. She said the same.
She cleaned up (with my shirt and towel) and we went to sleep.
We went home like nothing happened. But the next week i was invited to stay a night of drinking and talking, since we had so much fun.
I went over and, when he was in the kitchen, she said they had the best sex since years, while she was thinking of what happened in the woods. I was hard and she said she wanted to do it more often it there was any opportunity.
Since then, we created an opportunity every 1 or 2 months... she blows and as a reward i let her drink. its hot.
