Making Charli (1989)

Sinopsis

Jon Dough is a brainy college student who has just created a gorgeous female human being. His best friend Tom Byron, stumbles across this fuckable Frankenstein filly, falls in lust and seduces her to the pleasures of the flesh. She's a quick study, but when it comes time to take a shower, she literally melts away, leaving Tom baffled and broken hearted. Meanwhile, Jon has a study date with the luscious Ariel Knight, whose panties he would dearly love a to raid, but she's there to study biology, not practice it. So to put it in a nutshell, Jon builds Tom a vixen that won't melt, Ariel warms up Jon's idea of biology and everybody get's laid!
