Hurts to sit.

[JesterBDSM]

For the male slaves out there. Master/Mistress uses either a shute or just ties a loop around your nuts and pulls them back and ties them to your belt. Now your nuts should be around where your asshole is, now each time you sit down you'll squash your nuts. Have them/you wear this for a day.

Have you tried this? I imagine it is pretty unpleasant.
