Gansey hasn't done this enough to have any hope of it being something that impartial. And he has the luxury of being fairly unaware of the side of sexuality that is about obligation and influence. He has no resistance to the way that he takes him apart, can't even properly see the way that Declan does this to avoid the vulnerability of it.

But he's wrong that it'll be something Gansey regrets. Maybe something with leverage to it; but it would never occur to him that Declan might exploit this. Too new to this in a way that's almost naive- he gives so much of himself away, all affection and vulnerability, the soft pieces of himself he thought were better hidden than they were. Desire, want, attraction. He tries to say something, a warning as he hits the edge of what he can stand, but it comes out broken. A whimper and a moan and Declan's name all curled together as his body shakes like he might break.

It's different than touching himself. More, overwhelming, when his orgasm hits him it takes away everything else, makes everything else seem silent and still. He pulls his hand away from Declan's shoulder, trying to press fingers to his own mouth, muffle the sounds that he makes. Exposed down to heart and marrow.
