Tri-Volver is a strapless strap-on which can be worn without a harness or straps. This strap-on is ideal for couples and can be inserted into the vagina. Insert the short section while tensing your pelvic floor muscles. This ensures that the Slim Rider will remain in place. The wearer of the strap-on can penetrate their partner anally as well as vaginally. The wearer will be stimulated simultaneously. The clitoris is also stimulated through the vibrations of the small clitoris stimulator. The Tri-Volver is operated via the button on the side of the vibrator. The two motors work in harmony to create amazing stimulation for you and your partner. You will quickly discover its many functions and enjoy the three speeds and four vibration settings. The Tri-Volver is completely watertight which enables use under the shower or in the bath. This vibrator can be charged using the USB-cable provided. The vibrator can be cleaned with toy cleaner and lukewarm water after use.
