Pin Prick Collars

These are leather collars with pin prick spikes on the inside. The same kind that you find inside some chastity shorts for when there is punishment for unauthorized erections, also in full body harnesses that grips the slaves body, where any movement they dig into the skin, inside the seat of leather shorts to prevent the slave sitting (he knows he should be on all fours anyway), on spiked paw mitts, so he does not touch his cock (it belongs to you anyhow and he knows he needs permission to touch it  - however hard it is).

I really love these, they constantly remind the slave of his condition, giving him immediate corrective feedback. The spiked panels that go in the front on the Leather Chastity Shorts are further improved with electrical connection to alternate spikes so that it can be connected to a remote trainer or Tens unit.

The torture of the collar was implemented in the Netherlands. The collar was furnished with spikes and was held fast by cords stretching to the four corners of the room.
