What does it feel like to have someone piss in your ass?

I had this fuck buddy which lasted for 4 years, he was a neighbor and we’d fuck everyday. He didn’t really ask me to piss in him and I didn’t ask him for consent, it was just something that happened in the moment. like I was fucking him for 10 minutes then oh shit I felt the urge to piss at that time I thought it’d be inconvenient to pull out just to go take a quick piss, so I just pushed my dick deep in him and started taking a piss. it took like a solid minute to finish but it was definitely a new feeling, it’s like the piss is just getting sucked out of you haha, then I asked him if he’s feeling okay, he said he was fine so we just continued fucking some more till I finish in his ass, he goes back home and I go clean up too he never mentioned about it afterwards and I pissed in his ass a couple times more later on whenever I felt like it while we fucked but he never mentions about it. I didn’t really think about much it at that time but has someone else experienced this on the receiving end ? what was the feeling for you ?
