There's an added weight to this, knowing it is Fabrice's first time. Demetri can't explain how important it is that he enjoy himself, even more than Demetri's own gratification. Which is a first in itself, not normally the type to be that concerned about his partners, not since those first few times over a decade before that had gone so wrong. That wasn't to say he was a bad lover, but he was selfish. It's the opposite of what he feels now.

He tries things, his mouth following his hand in quick enough succession. Every time Fabrice makes a sound of pleasure, Demetri tries to make it intensify. Only when he thinks Fabrice is ready (and it seems to have taken hours and yet only seconds all at once) does he press inside with a finger, his movements slow and his eyes on the other man gauging his reaction. He tries to find that spot inside of him, waiting until he presses the second before finally closing his mouth over his cock, hoping the rush of pleasure will beat out any pain.
