Claire is feeling them up under the guise of "examining" them to make Matt squirm.

Karen keeps one on her lap and another around her shoulders and keeps striking them curiously.

Foggy is chatting him up while messing with them, squeezing them, rolling them like a baseball between his hands to keep Matt too distracted to realize they are all deliberately molesting his appendages until he can't ignore the rising scents of arousal anymore. XD
