BON4 is globally well known for its high quality male chastity products and we like to keep it that way. Customers requested we offer more toys for scrotal pleasure (or torture, if you prefer).
Our global reputation for top quality products is our most precious asset, so we hear and obey. (a corporate asset. Our most precious personal assets are…well, personal.) Here are metal and polycarbonate devices to impart pleasure and delightful discomfort.
You won’t know whether you’re coming or going. However, unlike with our chastity devices, you might cum if you love the mixture of torture and ecstasy!
  • Magnetically locked ball stretchers (MBS’s) in three weight combinations, all with a safe oval opening surrounding your dangling duo. Does greater mass around your ballsack create greater discomfort or pleasure? Both, you say? Lucky you!
    Here are all our MBS’s. Choose one or mix and match; The BON4MBS 24 & BON4MBS 36 work together.

  • Our visually stunning Humbler locks your scrotum, enforcing a humiliating, submissive posture as long as your Keyholder deems good for you. Orgasms in this ultimately submissive position, if granted, will deeply reinforce your dominant/submissive relationship.
  • Comfortable, easily emplaced cock and ball rings in hygienic stainless steel. Stay thicker and harder longer. If you’re granted release, expect flailing limbs and bellowing lungs!

Be sure to view the instructional video available for each product. We submissives don’t deserve these pleasure devices!
