Our peaceful home has been transformed into a "sex research lab"! A group of four sex-addicted high school girls call it "research" and throw a creampie party! They visit the home of a man they met at a phone club, forcibly occupy his house, and attack him! They do whatever they want, from teasing blowjobs to squirting cowgirl positions and creampie baby-making! They do a chaotic sex experiment until they run out of sperm!
