Ask yourself which is the likelier scenario, MIA. Scenario 1: This guy stumbled around your friend's dark apartment in the middle of the night, managed to find her underwear drawer, pulled it out and set it on the floor, made himself a pair of pantie-booties, had himself a wank, and fell back to sleep. All without waking your friend. Then your friend got up in the morning, saw her panties wrapped around his hooves, peeled them off one by one, and returned her panties to their drawer. All without waking Perv Hooves up. Scenario 2: Your friend got pervy with this guy, wanted to tell you about this guy's kink, but was too embarrassed to admit that she played along and possibly got into it.
