Chastity Jock – Large Cup

Our Large Cup Leather Chastity Jock is designed to look sharp, feel secure, and remain comfortable during extended daytime wear. For your hung partner that can’t fit in our traditional Chastity Jock. Built to balance restraint and wearability, it offers reliable control without sacrificing fit or appearance. While not intended for continuous full-time use, it performs exceptionally well for long scenes or day-long locking.

What it is

A leather chastity jock constructed to securely contain and control the wearer while remaining discreet enough to wear under everyday clothing.

How it hits

The jock applies consistent containment through a rigid leather cup and adjustable cock ring, limiting erection while maintaining comfort. An included keyring allows optional use as a buffer between the cock ring and a luggage lock, preventing metal contact against sensitive skin during wear.

Materials & build

Constructed from a single piece of riveted 7–8 oz latigo leather for strength and security. The interior cock ring is made from .75″ wide oily leather and attaches with Chicago screws, allowing easy removal for cleaning or adjustment. All hardware is selected for durability and long-term wear.

Fit & specs

• Choose your waistbelt size in the dropdown menu for best fit
• The jock is constructed from one piece of riveted 7–8 oz latigo leather, creating a rigid and secure cup, using one locking post.
• Two additional locking posts secure the belt (and optional J-Straps)
• An adjustable and locking .75″ wide oily leather cock ring is mounted inside the cup using Chicago screws for easy cleaning.
• A keyring is included for optional use to prevent a luggage lock from rubbing against the top of the wearer.
• Large Cup: Allows approximately 6.25″ of length and is intended for strained erections or wearers with larger anatomy.
• Both cup sizes can be concealed under jeans or heavier-weight pants.
• When paired with properly tightened “T” or jock-style rear straps, the cup sits firmly between the legs without creating outward bulge.
• Locks ride below most belt buckle positions to reduce visibility and improve comfort.

• Have the following items within easy reach: Chastity Cup, Waist strap, “T” or “Jock” ass straps, Locks (and keyring, if desired).
• All of the following steps should be done in a standing position.
• With one hand, pull your cock and balls away from your body (it helps if they warm and are relaxed), slip the Chastity Cup around your cock and balls from below making sure that the cockring is properly flipped inside the cup – not flipped to the outside of the cup.
• Holding your cock and balls in one hand, pull the cockring around your cock and balls with your other hand (just disregard the cups handling and position for now, focus on the cockring).
• Attach the left side of the cockring to the lower lockingpost, then attach the right side to the lower locking post – making sure that the cockring is tight but not uncomfortably/unsafely so. Notes: The cockring should follow the contours of your shaft – it should not be twisted the opposite direction. The cockring holes from side to side should not be off more more than one hole ie: if you used hole #3 on one side you should use hole #2, 3 or 4 on the other side but not hole #1 or 5.
• Install either a small padlock or the provided keyring though the cockring locking post.
• Pull any hair or folds of skin out of the cockring that might otherwise get pulled or pinched uncomfortably and adjust your cock and balls downward and comfortably positioned within the cup. Confirm that the cockring fit is proper.
• Flip the small padlock (if it is small enough) or keyring upward so it is not resting on the top of your shaft, then slid the upper locking post on the back right side of the jock through the hole in the back left side and then through the hole in the front of the cup and install the lock.
• Waistband with “T” strap: temporarily attach the waistband on the left waist locking post, feed it through the loop on the “T” strap and attach the other end to the right locking post. Confirm that the locking post holes are proper (that you are not using hole 1 on one side and hole 5 on the other side) – adjust as needed to center the belt on the proper adjustment holes, then lock the waistband locks. If this is your first time you may need to adjust the “T” strap loop location by removing the two chicago posts and lengthening/shortening the loop position and reinstalling the posts.
• Waistband with “T” strap plus Harness Straps: temporarily attach the waistband on the left waist locking post, feed it through the loop on the back harness strap, then the “T” strap, then the back harness strap again to make them interlock (See photos). Attach the other end to the right locking post. Confirm that the locking post holes are proper (that you are not using hole 1 on one side and hole 5 on the other side) – adjust as needed to center the belt on the proper adjustment holes, then lock the waistband locks. If this is your first time you may need to adjust the “T” strap loop location by removing the two chicago posts and lengthening/shortening the loop position and reinstalling the posts.
• Waistband with “Jock” straps: temporarily attach the waistband on the left waist locking post and attach the other end to the right locking post. Confirm that the locking post holes are proper (that you are not using hole 1 on one side and hole 5 on the other side) – adjust as needed to center the belt on the proper adjustment holes. Pull the jock straps around your legs and up to the right and left waist locking posts (making sure not to get them twisted). Confirm that the hole number is the same on both sides. Lock the padlocks on the locking posts. Move around, bend over, sit down – after you are sure you are happy with the jock strap position and adjustment carefully cut the excess strap off with bandage/medic scissors.
