Mike and Giovanni, two dorky friends from school, have been receiving sexy videos from Harlow and Summer, their bold and kinky stepsisters, and don’t understand why. Clueless, they try to figure out why they are seeing videos of their hot stepsisters show off their asses and tits in their faces. It turns out that the girls want to go to a big, wild party, but they’re not allowed to go unless they also take their geeky stepbrothers with them. They cannot just bring those nerds and have them creep everyone out–they have to wake up their manly instincts so they won’t be too awkward around girls at the party. Sadly, the videos don’t change Mike and Giovanni’s shy nature, and the party is right around the corner, so Summer and Harlow have to get creative and give their stepbrothers a crash course on how to be studs. When things get really hot, they decide it’s a good time for a foursome orgy…for practice, of course.
