If Sephiroth felt any concern over Zechs' reaction, then what follows rapidly puts such concerns out of his mind. The way Zechs' legs wrap around him, the way Zechs asks for it - those are signals, loud and clear, that Zechs knows what he can take and wants even more of what he's already getting.
Sephiroth is happy to give it to him.
He leans in to kiss Zechs, rather roughly, taking pleasure in the taste of him like this; just hearing him say those words was appealing. The fact that he breaks the kiss relatively quickly seems strange - up until he finally rocks his hips, thrusting into Zechs. There's no pause from there as he establishes a rhythm. What's more, that strength of his seems to serve him well; when he wants a different or better angle as he moves, he just adjusts Zechs to compensate. To some extent, this accidentally might serve Zechs' earlier fantasy; it gives a faint impression that he's simply an object for Sephiroth to rut into, one Sephiroth is casually repositioning as needed to maximize what he's seeking to get out of him. This likely isn't intentional - it may simply be that for some of Sephiroth's strength, it's just as natural for him to adjust Zechs' position as his own - but Zechs might view it as a bonus.
The fact that Sephiroth made sure to wait until Zechs' mouth wasn't covered by his own to start moving, though...it seems like he might really be pursuing that competition of theirs, not wanting to risk missing any sounds he might drag out of the other man.
