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.
