Experience a ménage à trois without all the trouble of finding a third participant with this adjustable thong-style double penetration harness by Sportsheets. Made from sturdy and washable nylon webbing, the harness is easy to put on and adjusts by pulling the ends of the straps through the simple ladder lock closures to tighten. Two O-rings are situated one on top of the other that can worn with one around a biological penis and one holding a dildo in place, or for wearers without a biological penis can hold two dildos.

The set comes with the harness itself, a silicone dildo, and four interchangeable O-rings. The dildo has a bulbous head, a smooth, curved shaft, and a rounded safety base that rests behind the O-ring when worn in the harness. Two of the O-rings are metal and measure 1.75" (4.4 cm) and 1.5" (3.84 cm) in diameter. The other two are nitrile and measure 2" (5 cm), and 1.75" (4.5 cm) in diameter.
