Given how quickly Thrawn's body was responding to stimulation, Astarion wondered how long it had been since he indulged in the touch of another. Not that he was unaffected himself- heat pooling in his belly, his own cock starting to harden though not yet straining against his underwear- that was likely to change soon enough though as he moved his hand to the other man's ass and pulled him down against him firmly at the same time as he pressed up. Guiding the buck of Thrawn's hips into a slow rhythm.

Keeping that hand where it was, the one in his hair moved- seeing no need to keep Thrawn's head where it was when the man seemed content to go for his neck, making Astarion's breath hitch- moving it instead to tug at his tunic.

Thrawn seemed to be a strong enough man- Astarion trusted him to be able to keep himself braced with one arm so that he could shimmy the tunic off with just a minor shift in position. One that wouldn't necessitate parting from each other.
