Pulse Pictures riffed on the American Pie franchise with the bisexual porn parody American Bi in 2006. Nothing but college-age hotties in MMF threesomes.
The concept proved popular enough that Pulse churned out three sequels — American Bi 2, American Bi 3 and American Bi 4 — then spun off a latino/latino/latina franchise — South American Bi, South American Bi 2 and South American Bi 3.
