Clearly, Master Series' Double Boner Bikini looked at regular strap-ons and said “what if everybody got more out of this situation?” Thanks for that!

Inside these stretchy silicone panties, an inner (penis-shaped) dildo takes care of whoever's wearing them, while they thrust with the outer (also penis-shaped) penetrator. The result? Hands-free fun for everyone.

Double Boner's built-in anal opening adds butt play potential to the mix, turning it into a seriously sensation-packed setup without adding extra straps or gear. And because everything’s built directly into the brief-style design, there’s way less shifting, adjusting, and “hang on, let me fix this” energy mid-session.

The Double Boner Bikini’s body-friendly silicone build is phthalate-free, easy to clean, and safe with all your favorite water-based lubes. Harness fits 22-50"/55.9-127cm.

*Inner penetrator: 5"/12.7cm insertable, 1.6"/4cm wide. Outer penetrator: 6.1"/15.5cm insertable, 2"/5cm wide.
