College girls study sex among their fellow students

Apparantly 'Sex in humanity' is a college course and these two girls (Sara Luv and Alexa Amore) are studying it. They are testing the result of porn on their fellow students. They start off by themselves though, toying their pussies because they need a bit of warmup before doing real research! That research consists of them seeing if any guy want to get their dicks sucked, fuck them or any other girl that's up for sex with some guy in the name of science! Turns out...a lot of them are!
