Male Chastity Device with Reverse Pegging

Keep that pecker under lock and key!

A two piece ring fits behind the scrotum. The lower part of the ring is curved backwards. Two pins on the front cage lock the ring pieces together. Once the front cage slides into place, it is all held together with a small cylinder lock, such as the Burg-Wachter ME/2 (https://www.amazon.com/Burg-Wachter-Lock-Blocker-Furniture/dp/B07P6HQV5T/) If you have a PA piercing, you can use a small chain over the pins, to prevent pulling out of the cage.

Reverse Pegging Attachment (RPA): Just because YOUR penis is locked up tight doesn't mean that SHE should go without! "Reverse Pegging" is when the guy uses a strap-on, instead of his penis, to penetrate his partner. It's a natural fit for someone in chastity. This chastity device includes a "Reverse Pegging Attachment" that fits over the chastity cage, and can hold a dildo with either a round suction cup base, or a Vac-u-lock attachment. Give it a try! But be warned: once your keyholder finds out that she can have you penetrate her using her favorite dildo, she may never let your penis out again!

The original RPA was in 2 pieces, Upper and Lower. The fit between RPA-Upper and RPA-Lower is intentionally snug. Use a small file on RPA-Upper until it slides into place on RPA-Lower without too much force. It is a small piece that only takes a few minutes to print, so if you mess up, you can print another without too much trouble.  A more recent, improved design of the RPA is a single piece, that snaps securely into place.  Also, there are two options for attaching a dildo: a flat surface/suction cup, or a Vac-u-lock style attachment. The suction option includes a "holder" that fits over the dildo to help hold it snug.

Dimensions: ring behind scrotum: 51 x 43 mm. Inside diameter of penis tube: 34 mm. Length of penis tube: 32 mm. Overall length of assembled device: 42 mm.  Gap between bottom of penis tube and scrotum ring: 17 mm.

I have uploaded a slightly larger version of the lower part of the ring, for those who find the standard size too tight.

For those who prefer a flat cage, I have published such a device, otherwise similar to this one: https://www.printables.com/model/1775971-male-chastity-device-flat-with-reverse-pegging. Check it out!

Notes:

Print the pins angled at about a 30-45 degree angle from horizontal, then glue them into the ears on the tube part. It will take a little work with a small file to get everything to fit together snugly, especially where the lock goes.

Print the one piece RPA on its side, with the top/bottom axis parallel to the build plate. The clips on the top and bottom are prone to breaking off unless the layer lines are oriented along the length of the clip.

The Files:
The chastity device requires 4 files: cage.stl, upperRing.stl, lowerRing.stl, and pins.stl. If the lowerRing is too snug, 'cc2025b.enlarged-NL-F.stl' is a slightly larger version.

There are a few versions of the RPA: 2 piece vs 1 piece, and Vac-u-lock vs Suction Cup. The 1 piece version snaps into place over the chastity device, and is very secure. The 2 piece version is an older design. It has a separate top piece, that slides in from the side to hold the top of the RPA in place. The Suction Cup version is only in the 2 piece version.

The Vac-u-lock itself comes in 2 sizes: the "standard" size, and a smaller version to use if the hole in the dildo is too snug.  If you have a favorite dildo, you can make it into a Vac-u-lock version by using a 1/2 inch hollow drill bit, such as: https://www.amazon.com/Diamond-Ceramic-Porcelain-Granite-Bottles/dp/B0B24RXXDJ/   After trimming the dildo to length, drill the hole, remove the material, and use the smaller Vac-u-lock device.

Among the files is an older version of the chastity cage, which uses bars to cover the end of the cage.  I believe it works with the RPAs, but I haven't tested it.
