when you have some pussy that is so amazing you have to exile your self into self induced rehab. Rehab pussy generally comes from a blonde with a big ass and big fake tits. She often will say "whaddaya gonna do for me" before intercourse. You know right away this means you have to lick her whisker biscut if you wanna stick the biscut. You will put up no fight because it is like crack to an addict. She has you addicted so badly you will even let her cup her butthole with her hand and fart in it only to make you breathe it.
jeses, that is some rehab pussy right there, I had it once and next I knew I was breathing her farts.
