Dave gives a hiss of his own, finally pulling his mouth away from sucking on Gamzee's horn, as saliva and blood mingle and drip over the tiny teeth marks the troll has left on his skin.

He keeps his hand working, on Gamzee's bulge wrapped around his dick, his grip slick and slippery and just right, and he uses the other hand, still tangled in Gamzee's hair, to pull the troll's head away from his chest.

"Gonna have to do better than that," he murmurs against Gamzee's lips, licking up a bit of indigo with just the lightest touch of tongue, before he dips his head and seals his mouth over Gamzee's neck, sucking and biting as hard as he can.
