In a private room, two heterosexual friends, Porter and Alex, let curiosity lead them to bisexual exploration. They start slow, kissing, touching, feeling each other's cocks grow hard. Alex takes Porter's cock into his mouth, swallowing it inch by inch, while Porter fingers Alex's tight ass. They switch, Porter eagerly eating Alex out before sliding his thick cock in, fucking him missionary, then doggy style. They cum together, Alex's load mixing with Porter's on his abs, their friendship forever changed by their taboo encounter.
