SpareParts Deuce Harness

The Spareparts Deuce is a unique harness which has been designed to assist in prolonging foreplay and as a brilliant alternative to continue love making sessions in between erections, creating further intimacy between partners.

The stylish Deuce is comfortable and attractive. The adjustable straps ensure it fits the wearer securely and remains snug and in place, providing complete control whatever the position. As the leg straps cross at the perineum, they apply a light pressure to the prostate region giving an additional pleasurable feeling.

The Deuce has an O-ring which feels natural and that expands and contracts to hold a variety of dildos of different shapes and sizes, so each and every experience can be a new and exciting one.

In addition, there is a second hole just below the O-ring that is lined with soft stretchable elastic which is designed to accommodate the natural girth of the wearer. This subtle touch to this unique harness, allows the second opening to act as a soft cock ring creating another pleasurable dimension when using the Deuce.

Both openings have two small flaps on the inside of the harness so that the wearer has the choice of having the dildo base against their skin for that more intimate and involved feeling or they can have it covered for a more gentler, less abrasive sensation. With the flaps that cover the second hole, the wearer can also opt to have their penis inside or outside the pouch. So you can enjoy the Deuce in a multiple of fun ways!

For additional vibration, the flaps for the top dildo can accommodate a wireless mini bullet vibrator for that extra sensual stimulation. Vibrating cock rings can also be used with the Deuce for a further titillating sensation to the dildo and to the penis.

The belt is secured with Velcro and has a second elastic pull feature for locking your product of choice into place. The locking mechanisms on the leg strap allow the wearer to move the sliders into place, whilst the locking teeth of the top slider holds the straps and harness in place so harness is secure the entire time it is worn. So the Deuce can be worn comfortably without having to constantly re-adjust.

The simplicity of the Deuce means it makes it easy to use for a variety of ways. The wearer doesn't have to remove the Deuce to insert their penis or the dildo through either one of the holes, while they are wearing it. They can simply release the belt strap and pull the pouch forward and insert or pull forward on either side of the pouch to insert.

The pouch is designed so that it comfortably cups the testicles and penis if desired, without resulting in bunching, chaffing, pinching or binding.

Its also a fantastic choice of harness for folks who have erectile dysfunction. The versatility of the Deuce means it can be used with only the dildo or with the penis and a toy simultaneously for dual penetration and double the fun.

Which size Deuce™ is for you?
Start with measuring for the perfect fit. For Deuce™ you will need to consider Belt measurements (hips), Leg measurements (thighs) and penis measurement (girth only) to determine which Deuce™ will produce the best fit for you, or your partner.

SIZE A or SIZE B: Follow these simple steps to determine which Deuce™ product will fit you perfectly! To determine if you or your partner is a size A or B, you will need to consider both the Belt and Leg strap measurements.

MEASURING FOR THE BELT: Wrap measuring tape around your hips, where you would wear your belt. Take the number where the tape measure completes and crosses over itself. You should add a few (3-4) inches to this measurement for size fluctuation and room for sizing adjustment. Take the measurement and see size chart above for Belt and determine which belt would be best.

(You should be able to select a size that is reflective of your pant or belt size. So if you wear a size 32 in pants, and they fit you securely, you should select the Deuce™ that best fits 32 inches).

Step one - To measure which size is best for the wearer; first figure out where you will be wearing it on your hips. The best way to do this is to put on a regular belt, as this will help you to have a place to start and finish measurement on the next step.

Step two - Next take the tape measure and start by taking the end of it and holding it in the center of the belt (in line with your belly button).

Slide the measuring tape between your legs. Select which leg you want to use for measuring and wrap the measuring tape taught around the back of that leg (around the butt check) and then bring it back around to the front back to the center of the belt where you started the measurement.

In essence you should have the measuring tape wrapped fully around one of your legs tautly (but not so tight it restricts blood flow) with the start and end point of the measuring tape being the front center of your belt.

Take the leg strap measurement, and then subtract 15 inches, this should give you the length of leg strap you need for the harness to fit securely but still be comfortable. See size charge above Leg Straps.

DEUCE™ OR DEUCE ™ MAGNUM: To determine if you or your partner requires a Deuce™ or Deuce Magnum™ product you will need to consider penis girth measurement.

PENIS MEASUREMENT: With the penis fully erect, wrap the tape measure around the base of the penis one complete time, and where the tape measure crosses over it self, take the measurement and see size chart above for Circumference of Second Hole Opening (For Penis).

    best made harness

    Posted by Dorothy J.

    Gave this to my husband he put me on my knees inserted his cock in the top hole - wow instant orgasm. Than after he climaxed I told him to insert a vibrator and continue on - wow again. The top o-ring exerts just the right amount of pressure while holding him in place, bam, again

    Texture and material construction: The Deuce harness is amazingly durable, and all of the materials are sewn together with quality in mind. This harness is going to last you a LONG time! Review Details: The Deuce harness is a very, very comfortable male-strap-on harness that is basically like the male-counterpart of the Joque harness for females. It has two holes, and the bottom-most hole is a bit loose with a "pouch" to help make room for everything. The upper hole is where the dildo slips in, and the dildo slips in really easily and really comfortably. The penis can slip through the hole on the bottom, or it can just be kept in the pouch. The boyfriend says that his harness is extremely comfortable, and while he had some slight issues learning how to properly fit it to himself (there are a lot of ways to customize it to your body!), he does love it now. It allows for double-penetration really easily, or, if you want, you can switch it up, and just use the dildo on the harness. You can also fit this harness onto a female, but the pouch might be a little loose (but she could always add two dildos for extra fun). Really though, the Spareparts Deuce is a GREAT harness that is amazingly comfortable for the boyfriend, and it holds the dildos nicely and makes double penetration possible.
