[Eichi supposes he will be able to tell if Tenn begins to panic at the very least, so with the nod his fears are assuaged enough to continue. He holds the leash taut and places a hand on Tenn's head as he slowly thrusts forward. The friction of his dick on Tenn's tongue, pushing into his mouth gains a low groan from Eichi. He's only ever had oral sex once, and while it was superficially similar, it's just not the same as doing it with Tenn, holding him on a leash and being told to fuck his throat.

Eichi tries, for at least this moment, to only go as far as Tenn's mouth will take, but he also tries to test his gag reflex before pulling back.]

I'm going to go deeper, Tenn.
