Double Penetration Strap Ons

How Double Penetration Strap Ons Work

A standard DP strap on harness holds one dildo in place for the receiving partner while a second shaft, built into the harness or positioned separately, penetrates or stimulates the wearer. That second shaft can sit inside the vagina, against the perineum or at the anal opening depending on the design.

Some double penetration strap ons use a rigid two-shaft frame where both shafts are fixed. Others use a flexible harness with a separate slot or ring to accommodate a second toy, which gives you more control over size and angle. If you already own toys you like, a harness with adjustable positioning tends to offer more versatility.

The key difference between a double penetration harness and a standard strap on is that the wearer gets stimulation too. That changes the dynamic considerably. Both partners are receiving something, which makes communication about fit, angle and pace especially worth getting right before you start.

Adjustable straps matter more here than with standard harnesses. The second shaft needs to stay in position during use, which means the fit has to be snug without being restrictive. Check whether the harness works across different body types and whether the straps are long enough for your measurements before buying.

For a different kind of hands-free penetration, strapless strap ons work without a harness entirely, held in place internally by the wearer. They suit a narrower range of body types but offer a more connected sensation for both partners.

If full penetration is not the goal, hollow strap ons are worth looking at separately. They serve a different function but sit within the same harness category.

Choosing the Right DP Strap On

The range within double penetration strap ons is wider than it looks. Here is how to narrow it down:

• Dual-shaft fixed designs - both shafts are built in and positioned relative to each other. Simple to use, but less flexibility if the spacing does not suit your anatomy.
• Harness with secondary toy slot - holds an existing dildo alongside a second shaft or toy of your choice. More adaptable, better if you already have preferences around size and material.
• Strapless strap ons - no harness, held internally. Different sensation profile, requires stronger pelvic floor engagement to stay in place.
• Hollow strap ons - designed to extend or assist rather than penetrate simultaneously. Worth considering if that use case applies.
• Vibrating DP harnesses - some include a built-in motor for clitoral or internal stimulation. Useful, but check battery placement and noise level if discretion matters.
• Adjustable-strap designs - essential for a secure fit during dynamic play. Look for wide waistbands and thigh straps that distribute tension evenly.

Fit, Lube and Communication

Use plenty of water-based lubricant. Double penetration involves more contact points than solo anal or vaginal play, so the need for lube is even higher. Silicone lube is not compatible with silicone toys, so check materials before you reach for the bottle.

Agree positions and pace before play starts. Both partners are physically involved in this dynamic, and small adjustments to angle or depth can make a significant difference to how the session feels. A safe word or signal is worth agreeing beforehand, particularly if one partner is in a position where verbal communication becomes harder mid-scene.

Build intensity gradually. Start with a familiar position, check the fit of the harness, and adjust before things get going rather than mid-use.
