XISE

Xise is a narrow shelf, but what is on it covers several uses at once: a realistic vibrating dildo at around 25 cm, built from silicone over a TPE body, with a suction cup base that is also harness-compatible. That base is what gives it range, since it can be fixed to a smooth surface for solo use, worn in a harness with a partner, or simply held. It is waterproof and charges over USB. The length puts it firmly at the larger end of the realistic category, so this is not a first purchase and is better worked up to than started with. Use a water-based gel given the silicone surface. Shorter versions of the same idea sit under realistic vibrators.
