[It would be easy to get lost in thrusting into Ethan's mouth like this, and he grabs onto a fistful of his hair to keep him where he is while his hips work. He's getting close already, riled up as he was from fucking Ethan with those vines, so Ethan admittedly doesn't have to work hard- but the feeling of a tongue against his cock again makes him groan. He's not unaware of the fact that Ethan's hips lifted though, and he lets out a soft "heh" as he moves.]

Getting off on this..?

[He knows what Ethan could do with his hands.]

Go on then, touch yourself.

[Not that either of them can see it, but the knowledge would be there- that Ethan was getting off on having his mouth fucked.]
