Not with the way he kisses him back, smiling hard against the gesture and quickly finding somewhere comfortable for his hands to settle. The other's hips, maybe. Seems like a good place to start, with one gloved hand sliding down over his thigh in antsy anticipation.

This could be fun. When's the last time they had this kind of fun, huh?
