When Hythlodaeus starts to rock along with what Emet-Selch is doing with his mouth, he gives a pleased hum, washing his tongue warmly over Hythlodaeus' cock as reward. Then he slowly draws back, making sure his lover is watching as he carefully licks his lips afterwards.

"Oh, very much so." He practically purrs up at Hythlodaeus before he leans in to kiss and lick along the shaft of his cock, sucking his sac. He doesn't want to finish here and now either but he definitely wants to make Hythlodaeus squirm.
