banana buttcrunch

Another slang term for analsex. You basically fuck a girl
up the ass so good, and so hard, she"s left feeling like it was just put through a meat grinder.

p.s.
you must have a curved dick for this to be authentic.

blueberry buttcheeks

Blueberry buttcheeks are when your bottom is spanked so hard and for so long that they no longer resemble rosy cheeks but instead look more like a blueberry tart. The spankee is usually in floods of tears at this point.

Uncle Richard threw me over his knee and gave my ass a damn good thrashing because he felt I was being impertinent. The fact I'm 39 and a headmistress and his penis erect throughout notwithstanding, I felt it wrong that he should leave me with blueberry buttcheeks for a simple misunderstanding. I came home and applied some antiseptic cream and slowly my ass is feeling like its old self - heavily sagging and puckered from all the ass fucking my husband seems to enjoy.
