Deuce from SpareParts is the first harness designed especially for penis-owners.

Deuce is a solution that allows you to continue in between erections and is an excellent tool for double penetration.

Two separate holes allow for the penis to extend through one and a toy to extend through the other.

An internal pocket holds a vibrator for extra stimulation.

Leg straps lightly cross over the perineum for added pleasure.

Comfortable and completely adjustable, it can be worn for extended periods and makes it a great solution for men with erectile dysfunction.

Deuce Harness features:

  • Materials: nylon, spandex, velcro
  • Adjustable leg straps and belt
  • Elastic and stretchy O-ring that expands and contracts to fit a variety of dildos
  • The second opening below the O-ring accommodates the wearer’s girth and functions like a soft cock ring
  • Option to place a mini vibe in the flaps of the first opening for extra stimulation
  • Great for water play

This Toy: 💘 Date Night Favorite



Brings excitement, connection, and definitely stays charged and ready.

Who is this harness for?

The Deuce Harness is ideal for:

  • Penis-owners experiencing ED or premature ejaculation who want to maintain intimacy and enjoy penetration even when erections come and go.
  • Anyone exploring double penetration—the dual openings accommodate both a penis and a dildo simultaneously.
  • Transmasc folks seeking euphoria and control with gear that supports both penetrative and affirming play.
  • Folks with limited hand or arm mobility who benefit from stable harness support for toy-assisted penetration.

How to use the Deuce Harness?

  1. Choose the right size based on your waist and thigh measurements before putting the harness on.
  2. Insert your dildo of choice into the stretchy O-ring at the front. Ensure a snug fit for stability during use.
  3. Slide your penis (if applicable) through the second lower opening for soft or erect play, or skip if not needed.
  4. Tighten the waistband and leg straps for secure positioning. Adjust for comfort and control.
  5. Add a mini vibrator to the internal vibe pocket for clitoral or perineal stimulation if desired.

Great positions to try:

  • Missionary: Allows for eye contact and control of rhythm with harness support.
  • Doggy style: Great for deep, steady penetration using your body weight with hands-free control.
  • Rider-on-top: Encourages exploration with the harness wearer getting to relax and enjoy stimulation in between thrusts.

How to clean and care for the Deuce Harness?

  • Cleaning: Hand wash in cold water with mild soap. Do not bleach or machine wash.
  • Drying: Hang dry completely before storing. Avoid tumble dryers or direct heat.
  • Lube compatibility: Harness does not touch genitals directly, but ensure dildos used are silicone-safe (use water-based lube).
  • Storage: Store in a cool, dry drawer or pouch. Keep away from rough or sharp objects to protect the stretchy ring and fabric.

Harness practical use info:

  • Double penetration: Allows for penetrative play with both penis and dildo at once.
  • Prolong penetration: Continues the fun between erections or when length/stimulation needs vary.
  • Water play approved: Quick-drying materials make it great for shower or tub play.
  • Versatile: Suitable for cis men, transmasc folks, and anyone exploring adaptable gear.

Additional information:

  • Erectile difficulties: Deuce can help maintain intimacy even with inconsistent erections.
  • Motor limitations: Can assist folks with limited upper mobility by stabilizing toys during use.

Special considerations when using Deuce Harness:

  • Mobility required: Some bending and adjusting needed to wear and tighten.
  • Dexterity: Users need basic hand coordination to strap in and switch toys or place vibes.

User experience tips:

  • Test fit solo before introducing during partnered play to get comfortable with the setup and adjustments.
  • Pair with a curved dildo for prostate or G-spot stimulation and deeper penetration angles.
  • Try a vibrating bullet in the harness pocket for extra sensation during double penetration play.
  • Lube the penis opening slightly when going flaccid-to-erect to reduce friction with fabric lining.
  • Wear it under clothing to surprise your partner during date night or for discreet kink vibes during roleplay.
  • Allow time to fully dry if using in water—moisture trapped in layers may prolong drying time.
