After catching his boyfriend fucking his dad, Zac is a bit more than conflicted. He doesn't have anyone else to turn to except maybe his step-dad, the one married to his cheater of a father! Zac goes to Derek to confide in him and gets a little bit of advice that he wasn't expecting: it's not cheating if you do it back. The two decide to fuck it out themselves and call it all square... all according to plan.
