[Sandalphon watches in blissful, rapt attention as Izumi's slender hands pump his cock, and he feels himself twitch inside Izumi just from watching. The thought of Izumi touching himself, thinking of him—being able to see it—it's all so much.

He keeps his rapid, hard pace, slamming into Izumi, breathlessly and desperately murmuring more instructions:]

T-Tell me if you're ready to cum, I...not yet, not yet, we've got so much more to do...

[When Sandalphon's in heat, he can frequently go multiple rounds before getting soft, but if Izumi tires out before he does then it doesn't matter how long he can keep going. He's sure Izumi is just as ravenous as he is right now, but even so, prolonging it just means they'll both feel even better...]

You're so good, Izumi, you feel so amazing...mmm, h-here...comes the first load...

[He'd be embarrassed to be cumming so early if it weren't his heat, but his body is so sensitive, it can't be helped. He spills his seed into Izumi, thrusting himself in to the hilt so he can pour as deep as it can go.

And after a few seconds of shuddering, riding out the orgasm, Sandalphon resumes fucking him as though it had never happened, that white-hot pleasure already building again at the base of his spine and between his legs.]
