There was no cheating in love and war, was there? Or in bed, as far as Kirk was concerned. But it was definitely to his benefit that he knew all the sweet spots on Caboose, how to caress, where the pinch, what to lick. He enjoyed finding them, enjoyed finding them again and again. His head slid further down, tongue flicking across a dark bud, swirling around it before closing his lips. He sucked and tugged, his hips grinding slow and hard against Caboose's.

"Think you could put on your pretty little collar tonight?" he purred against wet skin, rolling the bud between his teeth.
