Astarion's eyes briefly flicked to his hand as Thrawn pinned him down by the wrist, though he was quick to turn his attention back to him- a shiver racing down his spine as the other man's fingers wrapped around his cock, sending a rush of pleasure through him and making the muscles of his stomach contract and his legs twitched and then squeezed tighter around him as he let out a pleasured sigh.

"Mm- I could ask the same of you," He purred, definitely liking the feel, but deciding that he didn't want to give him the satisfaction so easily. Lust-darkened eyes and white porcelain-like skin dusted with a red flush likely told him enough, so he felt like Thrawn should have to work a little harder to get the reward of hearing him say it, "You seem to be liking how I feel quite a bit, darling-"

To punctuate that, he clenched around him- squeezing tighter around his cock. Idly pondering whether he'd be rewarded with another hiss- or perhaps a curse.
