We are very happy to offer you the latest version of The Holy Trainer—the V3. This updated design offers a comfortable (but not too comfortable!) fit so that your keyholder can deny you pleasure for days on end. It’s discreet enough to wear under clothing while you go to work, the gym, the supermarket, anywhere! No one but you and your keyholder will know what a naughty boy you are.

The unique internal lock-and-key system keeps your cock secure without the need for a padlock. All of our kits come with two keys so you can give one to the one you serve and keep the other in a secure place for emergencies. But we know you’ll be good and only use it in emergencies!

We offer four different cage sizes: nano (smallest), small, standard and maxi (largest). If you’re  a returning customer, we’re sorry to say that the older V2 rings are not compatible with the new V3 cage but don’t worry; we supply all four ring sizes (36mm, 40mm, 45mm and 50mm) with the V3 kit so you won’t have any issues. Experiment to see which one works best for you before locking it up and handing over the key.

The naturally sourced bioresin is durable, comfortable and sleek. The shine of the dark black material is a sexy look and is sure to delight your keyholder. And unlike the clear or pink devices, with this one you won’t be able to see your pathetic cock as it suffers in its beautiful cage.

The material is completely waterproof and easy to keep clean. Two holes on the side for ventilation mean you can keep the device on while you shower and it will be nice and dry afterwards; and the front hole for urination means you’ll never have the need to take it off; only your Master or Mistress will be able to decide that.

This kit is also available in clear or pink; choose the one your keyholder will like best. Please check the measurements before ordering to ensure satisfaction. (Just not too much satisfaction, of course.)
