[Izumi might be able to feel Sandalphon's lips curl into a smirk against the back of his neck when he grinds back against him.]

One last thing, then...

[Sandalphon returns his attention to Izumi's ear and whispers lowly into it as he pulls out of him.]

I want to hear every noise you make, so don't you dare hold back.

[With that, he rolls Izumi onto his back and slides into him again in one fluid motion. Just another moment to adjust the angle of his hips as he pulls out, and then...

He drives his cock as deep as he can, as hard as he can, immediately adopting a rapid, forceful pace. His own moans slip ungracefully from his throat, every inch of him lighting up in an intense, overwhelming surge of pleasure. It's been difficult for him to hold back too, his body screaming to breed Izumi until he can't walk, to fuck him until he's only capable of thinking of his cock, and then to fuck him some more for good measure. Izumi wanted to be filled up, and Sandalphon is more than willing to oblige—he'll spill his seed inside him until he begs him to stop.]

Let me see you touch yourself, I...nnn...want to see how much you want me...

[He's got both hands firmly on Izumi's hips to keep a steady rhythm, or else he'd do it himself.]
