Neither Zac nor Chris want a relationship. It sort of sneaks up on them. And then the lines become blurred. When Chris approaches twenty-two-year old Zac in a bar, he's floored by Zac's announcement. "I'm twenty-two. No boyfriend. No partner. And seriously considering taking a vow of celibacy." The more Zac shares, the more Chris feels he can help Zac. And after one visit to a club, Chris knows what turns him on. Zac likes to watch. Lucky for Zac that Chris can help him with that. In fact, Chris can blow Zac's mind. When forty-two-year-old Chris tells Zac of his intentions, Zac is intrigued. "I don't want to know what makes your engine tick—I wanna know what makes it purr. I wanna watch you, learn what your boundaries are, how far I can push them." And push them, he does. Each new experience is hotter than the last. Kinkier too. But somewhere along with the way, Zac stops wanting to be 'f***-buddies who don't f***.' He wants more. But Chris doesn't want that – does he? They're not in a relationship, right? Yeah, right.
