There is no other voice, at least not yet. Xue Yang is giving Song Lan this cruelty disguised as kindness as he remains quiet, not letting his voice remind him just who it is who's fucking him. The closest is a soft gasp that he deliberately lets out when Song Lan squeezes around him.

But then he's fucking him harder, hard enough that the sound of their bodies slapping together probably makes it to the device. If this is the sort of thing Song Lan enjoys, Xue Yang is absolutely going to give it to him in this moment. He fully intends to fuck him until he can't think anymore, just as promised.
