I've experienced that while backpacking thru Europe in 1985, I had a threesome with a couple in Daroca, Spain, and after I fucked her, she wanted him to fuck me. I was hesitant because his penis was really thick and I don't usually bottom for big penises. They promised he'd go slow, so she and I did 69 while he slowly fucked me. It wound up feeling really good, he was really deep inside me and it wasn't as painful as I had thought. I remember sucking him afterwards and he was uncut and noticed a little of my 'stuff' under his foreskin. He was my second uncut experience at that time.
Booo, she wiped. Although it will still smell like her fecal material and ass, it’s not true dirty ass to mouth. If she was drunk, she might have taken it straight into her mouth, as several experiences I’ve had suggest alcohol tends to soften the woman’s objection to consuming her poo goo.
