A double penetration kit that lets you live out your group sex or get-it-from-every-angle fantasies comfortably and easilyeven if it's just the two of you. A penis or a dildo slide through one of three included ring sizes (1-1/2", 1-3/4" and 2" in diameter), while the other sports a Tantus silicone dildo (5" x 1-1/8"). As easily as strapping on the ultra-expandable harness, you'll be ready for simultaneous vaginal and anal penetration while leaving your hands free. To fully appreciate the charms of the Menage a Trois, we recommend the doggy-style position.
