Strict Double Penetration Strap On Harness by XR Brands

A premium leather strap-on harness delivering dual penetration with three graduated silicone dildos—one for your partner and two that fill your vagina and anus simultaneously during power exchange sex. Perfect for experienced couples exploring mutual pleasure and control.

What it does

This harness system lets you experience dual penetration while you control the action. You wear the main 7-inch cock to fuck your partner, while two internal dildos—one in your vagina and one in your anus—stay in place during every thrust. Both internal pieces move with your body, creating constant massage against your vaginal and anal walls as you build rhythm and depth.

Your arousal builds steadily as the harness transfers all your motion directly to the internal attachments. Pressure accumulates as you thrust, combining physical fullness with the psychological rush of wielding the primary cock for your partner's pleasure. Strap On Me covers the full range of harness styles and configurations for different scenarios. As you increase pace, the firm silicone pieces massage your internal walls continuously, driving you toward orgasm while your partner experiences penetration from the main dildo.

Fit and sizing

Measure your waist and hips to find your starting point within the 25–41 inch range. Thigh circumference also matters—the crotch strap extends 20–23 inches, so check that the leg loops sit comfortably without pinching. At Cockringshop, we specialise in products for men and couples, and we know that comfort beats ego every time. A snug fit prevents slipping during vigorous thrusting, but you should be able to fit two fingers under each strap. Start with the shorter anal dildo (3.8 inches) if you're less experienced with anal penetration, or progress straight to the 5-inch vaginal piece if you're already comfortable with fullness in both holes.

How to use it

Adjust all straps snugly around your waist and thighs before insertion. Lubricate the vaginal and anal attachments thoroughly—silicone works well with water-based or silicone-based lubricant. Insert the shorter anal dildo first, then slide the vaginal piece into your vagina until both feel secure and positioned naturally. Fasten the main harness so the external cock extends forward at a comfortable angle for penetrating your partner.

Start with gentle thrusting motions to accustom yourself to the dual internal sensation. Test the fit by moving your hips—everything should stay firmly in place without shifting or pinching. As arousal builds, increase your pace and depth. Your partner can guide the depth and rhythm by communicating what feels best. After use, wash all silicone attachments and the leather harness with warm soapy water, dry thoroughly, and store in a cool, dry place away from direct sunlight.

Feature breakdown

Who it suits

This harness is ideal for experienced couples exploring power dynamics and dual penetration fantasies together. You'll love it if you crave fullness in both holes while maintaining control during partner fucking, or if you cum from internal pressure combined with the psychological thrill of wearing a cock. Graduated sizes work for both anal beginners (starting at 3.8 inches) and those already comfortable with larger insertions. Adjustable sizing accommodates various body types, so fit is customisable rather than one-size-fits-all.

Skip this if you're new to anal play and want to start smaller—the 3.8-inch anal dildo is moderate, not minimal. It's also not the right choice if you prefer external-only stimulation or if you're uncomfortable with the sensation of being filled internally while you penetrate your partner. Solo use is possible but the harness is designed for partnered power exchange, so you'll get more from it with a willing partner who enjoys receiving penetration.

How it compares

Double penetration harnesses differ from single-cock strap-ons in that they fill you internally while you fuck your partner externally. Single-harness designs focus all sensation on your partner; this one splits pleasure between you both. Some couples prefer the simplicity of a single external cock, while others want the added fullness and arousal boost that internal pieces provide. Pornhub Sextoys offers other strap-on styles if you want to compare single versus dual designs. Your choice depends on whether you want internal stimulation during the act or prefer to focus entirely on your partner's pleasure.

What you can use it with

Pair this harness with vibrating cock rings or remote-controlled vibrators worn by your partner during use—the added sensation can intensify both your orgasms simultaneously. Couples Intimacy Kits combine complementary items designed for partnered play, letting you explore power exchange scenarios with matched tools. Bondage restraints or collars can heighten the psychological intensity of the power dynamic, while blindfolds add sensory focus. Communication and comfort matter most—discuss limits and safewords before you start.
