This new adaptation of the dual insertable vibe to be used during partner penetration conveniently works with a remote control for hands-free fun for both partners. The narrow “fold” in the middle easily hooks into the vulva, with the unique, heart-shaped clitoral stimulator covering the most important bits of clit, clit hood and inner labia. The 3 ½" by 1 3/8" internal vibe has a slight scoop on the back to add some comfort for penetrative penis pleasure. I found it pretty comfortable to insert and wear when I experienced this action-packed accessory, and my partner shared that the size of it wasn’t too big to interfere with his pleasure. It certainly added a lot to mine!
