Basically, the title says it all... a girl is given the freedom to screw around on her boyfriend.  What this means is that she engages in a limited number of threesomes with other guys, including one team consisting of a body-sculpted stud and a rail-thin guy.  After Mr. Muscle pops his load in her downy cooch, the scarecrow reaches in to play with the spent sperm.  Not for all tastes.
