Alex is crazy about his girlfriend, Sarah. They've been dating for a while and he thinks he's found the one. But Sarah has a secret wish - to be with another man besides Alex. One day, while they're out at a bar, Sarah confesses her desire to Alex. Against his better judgment, Alex agrees to introduce Sarah to another man - an old friend from college named Mark. Unbeknownst to Alex, Sarah has been fantasizing about Mark for years. The two of them hit it off immediately and before long, they're making out passionately in the bathroom of the bar. When they emerge, Alex is shocked to see his girlfriend so turned on and satisfied. But instead of being upset, Alex realizes he's turned on by watching them together and wants in on the action. The threesome continues back at their place, with Alex and Sarah taking turns pleasuring each other while John watches and masturbates, building up his own sexual tension before joining in.
