Extra cages to fulfill your Keyholder's need

BON4M separate cock cages in all sizes

NEW – According to the mails we received there’s a growing need for separate cock cage sizes.
Additional cage sizes are more pleasurable and offer more options to you as well as your Keyholder.

Does Your Head Swell?
Does Limited Growth Make You Tight?
Many Keyholders and submissives feel the need for a second BON4M cage. As we all know, our penises lengthen and thicken or shrivel away in response to temperature, our garments, and our emotional state, not only to sexual arousal or lack thereof. Keyholders may feel it’s necessary to tightly constrain their partner as punishment or humiliation or conversely to increase frustration by allowing partial growth short of a full erection, let alone a satisfying ejaculation.

  • Submissives, please your Keyholder with a gift of a cage in the next smaller size. Show your devotion by asking nicely to be more restrained.
  • Submissives, obey your Keyholder and purchase a cage in the next larger size. Be dominated & humiliated in a larger cock cage.
  • Experienced Keyholders with multiple submissives may be able to fit more than one cage by distributing the rings and spacers among them. Unique families like these require more than one cage.
  • Only compatible with the latest launched hinged BON4M Series.

As always, prompt international shipping in discrete packaging.
