A sexual act wherein a person fucks another in the ass and the person who was fucked immediately performs oral on the fucker without clean up. Sometimes called ass-to-mouth (a2m) in the porno industry.
I fucked Sandy's shitty dirtpipe, then pulled out before jizzing so she could finish me with a brown bj.
