Everybody in the pool, clothing optional.
If you masturbate to only one pool scene then it should be Phoebe Cates in Fast Times at Ridgemont High (1982), a classic of teenage arousal and release, and being caught in the act. Okay, maybe if you watch just one pool scene it should be Elizabeth Berkley in Showgirls (1995), where she gets completely naked and fucks her man to an orgasm that has to be seen to be believed. You know what? We can't narrow down the pool scenes to just one, not with hotties like Jaime Pressly in Poison Ivy 3 (1997) getting topless and wearing an ass-revealing thong as she dives into the pool. We just hope you have a lot of spunk in you, because you'll need it. We've not even yet begun to get started. Naked from behind, and what a behind, Beau Garrett in Entourage (2004) is sure to get top billing in your fantasies. It's really Cathrine Bell as Isabella Rossellini in Death Becomes Her (1992), but it's still hot. Neve Campbell and Denise Richards in Wild Things (1998) get les-be-wet in the pool. Charlize Theron in Reindeer Games (2000) and the games start with the removal of her bathing top in the pool. T&A from Camilla Luddington in Californication (2007) playing a naughty nanny. Is there any other kind? When Orla O'Rourke in Strike Back (2010) comes out of the pool topless you'll lose your head. Jane March in Color of Night (1994) falls into the pool and then into the bed and never with any clothing to obscure her true colors.
That was refreshing.
