Oh, fuck that shit - Dave's not about to be naked while Gamzee flits about in all of his ridiculous clothing. He struggles out of the rest of his shirt while Gamzee attacks his pants, and then his calloused hands are sliding all over the troll, tugging and pulling at fabric and fastenings.

With Gamzee's mouth occupied on his neck, he finds the troll's horns are in easy mouthing reach, so he eagerly applies tongue to long, curved horns.
