Yes & no 🙂
Your fucker was smart to get into the shower -- just incase there was extra ... dirt 🙂 And to clean up eitherway. Plus shower fucks are HOT!
I've had 2 poopy encounters where I had to leave w/out getting off: 1) bottom basically had a bowl movement on my dick, 2) bottoms bumhole smelled worse than farts as I fucked. Smell can be a HUGE turn off when it gets out of control. And I'm not into Scat either.
Aside from that, my hubby and I have had lots of success with unprepped fucks. His bumhole is ALWAYS clean -- dam lucky good genes but it's a real shame he doesn't bend over more often b/c it's like his ass is just built for unprepped / sponteanous fucks! ugh. For my ass: I have to get fucked in certain positions. Riding a dick unprepped is a BIG No-No for my fuckhole b/c my crap ... tends to "move" down when sitting. When I was young & dumb (20yo), there were some nice fuckers who said "shit happens" but they usually had to leave w/out cumming. I quickly learned that a High Fiber diet & bent over is usually fine for unprepped.
