TITLE: TIFU by shitting myself during sex. [NSFW]
POST: Okay so like many other FU's this story is a few months old but I figure i may as well tell it. 

There was a girl I had been talking to for a while. We'd been friends for probably two years but the entire time she'd had a boyfriend. I'd pretty much resided myself to knowing that nothing sexual would ever happen between us, but enjoyed her company nonetheless. 

Anyway, after years of waiting she finally broke up with her bf, and me being me I swooped in asap. We started to get pretty flirty, and then we finally admitted (much to my surprise) that we both liked each other. There was a party a few days later and we planned on seeing each other there, and it was pretty obvious that we both intended for more. 

So at the party it got pretty late, and we were both pretty drunk when we decided to hook up. Things started heating up so being the quality house guests we were, went up to a bedroom. We started getting it on and all was going well....until I started to feel her fingers fairly close to my asshole. "Bit weird" I said to myself, but id waited for this moment for so long I decided to go along with it. Then i felt some downward pressure, and the next thing I know she's fingering my ass while of on top of her. I played it of, somewhat because I was drunk, and somewhat because i was getting laid. 

But then came the moment of climax. She must've been able to tell that I was close, because as soon as I started to...y'know...she removes her finger, and WOOSH, I released a steady stream of liquid shit all over the bed, and all over her. I screamed with embarrassment, and got straight of. 

The kicker though: After hopping off and observing the damage i had caused, i looked up at her, only to be met with the response "Oh, not you too"
TL;DR: 
After waiting 2 years for a girl, we had sex. She fingered my ass and then I shat all over her while climaxing.
