this happened many years ago. I was at a gay club enjoying myself in the corner when this cute twink said hi and dragged me to the dance floor to dance. Long story short, we both got increasingly tipsy and frisky, and since we both couldn't host at that time, I suggested checking in to a nearby budget hotel to "rest and spend the night". Guess everyone can insinuate the subtext here
Once the door closed behind us, we immediately started pawing each other and trying to get naked; we could both feel the arousal in our groins as we tried shedding our clothes while hugging and making out. After a bit of foreplay, he lifted his ass in the air and I went in doggy style at the foot of the bed. After getting used to me in him, I started pumping away for less than a minute when he suddenly groaned out a "wait... stop..." which I mistook as him moaning in pleasure; he had been rather vocal beforehand.
"you like it? Enjoying me in you? Like being filled???"
"no no wait...", and this time, he used his right palm to firmly push my thigh away.
My cock made a soft puckering sound as it exited from his ass and I noted the condom was stained rather brown. I was about to ask if he was ok when he suddenly groaned loudly and his ass suddenly spewed out warm matter everywhere. Shocked, I looked down and my entire torso was covered tiny droplets of fecal matter. The whole room stank to the high heavens, and I quickly escaped into the toilet to wash off while I continued hearing loud wet farting sounds. After a thorough shower and scrub, I came out and examined the crime scene: OH MY GOD THE ROOM WAS IN A STINKY SHITTY MESS. There were droplets of shit all over the wall and TV behind where I was, and apparently more watery diarrhoea came out while I was washing up, and it was now dripping from the foot of the bed onto the floor. Twink was seemingly knocked out from the prior alcohol, exertion from sex, and his stomachache, so I got dressed and bolted the hell away from the room while he continued sleeping in his poop.
When I walked past the reception, I told the dude on duty "I managed to wash my drunk friend up and he's sleeping now. I'll pay for an extension till noon". He simply nodded and wordlessly took the cash. I was thankful he was more interested in the show playing on his phone screen and didn't seem to take much note of me.
Since then I've been extra hesitant of having fun with anyone who's drunk and not really in control of his bodily functions. I can understand a bit of poop on the condom (hey, shit happens lol) but wtf, projectile bits of shit everywhere was really scarring.
