This clip is an homage to that scene in Revenge Of The Nerds where they spy on that girl masturbating! see if it parts of it look familiar to you.

Abby is getting increasingly pissed off at her dickhead of a boyfriend, she's on the phone with him as he pleads to come over, telling her he's horny, well Abby is horny too but she's having none of it, she tells him to piss off and lays back on her couch to take her of her own business! sensual and hot as it will certainly please you to watch Abby please herself! and oh, check out that ass!
