Nice idea! Hmm, now where were those clamps go? And which direction would they get pulled when cranking the ratchet? Maybe his nipples get clamped, and a ratcheting rope from the nipple clamps down to a lower anchor point...so every time he goes up on the dildo he pulls his nipples. Or I could anchor it above him, so every time he goes down all the way on the dildo, his nipples get pulled. Sooo many possibilities! How would you rig the clamps and extra ratcheting device?
