Tantus Strapless Slim Vibrating Strap-On Dildo Azure

The Tantus Strapless Slim is a vibrating strapless strap-on: one end is a bulb the wearer holds inside, and the other is a slim 5.5-inch shaft that sits at a natural angle. There are no straps to adjust, so you get skin-on-skin contact.

Tantus made it 10% lighter than its original strapless model, so it is easier to hold and control. A removable waterproof bullet adds vibration for both partners. It is 100% silicone and dishwasher safe. This is the azure colour.

From Tantus’s product description.

1. Use plenty of water-based lube on the bulb.
2. Insert the bulb while lying down, and squeeze your pelvic floor to hold it.
3. Start in positions where your partner moves, not you.
4. Hold the base with a hand until you are confident.
