Yeah. It's his. It's been his for a while, even if he didn't know it. Cloud might be embarrassed at how soft that thought would make him feel if he had the attention to spare for it right now, but Zack's fingers have claimed it all.

Waves of pleasure wash over him like a rising tide, and each one leaves him in a breathless whimper that he muffles by burying his face in Zack's hair. His own fingers dig into the bare, wet flesh of Zack's back as his whole body tenses in little shudders, pressed up against the heat of the other man's body wherever he can be. He doesn't mean to make Zack's job harder with the gentle rocking of his hips, but he can't help trying to rub his cock against him like before.

"Zack..." Nothing but an aimless plea, just saying the name aloud to taste it on his tongue in quiet awe at the reality of being with Zack like this.
