he Sweet Sensation is, in (totally unique) form, a smooth triangle topped by a spiral-textured swell. In function, it's the absolute perfect vibe for treating sweet spots (the clitoris is an obvious target, but it's perfect for nipples, head of the penis, ears, toes, anything goes) to 15 modes of deep, resonating vibration. You can hold it in your hand, have a partner hold it in theirs, or, like the name suggests, lay on it. The Dark Desire is IPX7 waterproof, and is safe for submersion up to about 3.2' (1 meter) for no longer than 30 minutes. Material: Silicone USB rechargeable, cord included. 3.5 hour charge time for 50 minutes of play. Length: 3.6" Girth: 6.9" at largest point Width: 2.1" at largest point
