I love slippering well perhaps not so much when I'm the one bending over! An retro style plimsoll is perfect. And yes trunks pulled up tight between the cheeks leaving your bum exposed is great for punishment.
That sounds great, I have never been slippered, only caned and paddled. Swim trunks would be horny or even getting a wedgie before the punishment sounds horny
Oh absolutely. Always exciting to have the shorts pulled up high into the crack to fully show off the arse, and makes great viewing when watched after a caning.
