In plushy, squeezable silicone, this vibe bends and flexes for perfect positioning, but it's absolutely firm enough to satisfy. Which shaft you choose to use where is entirely up to you - play with one at a time, or take advantage of both for that true DP experience.  
Cue up twelve super-star modes of deep, throbbing vibration with a simple button below the base. 
In silicone and ABS plastic, the Over & Under Power Stud is phthalate free, body safe and super-easy to clean. Before and after playtime, wash Curvy well with lots of warm soapy water or a good toy care fluid/foam. This vibe can be safely enjoyed with any favourite water based lube. USB rechargeable (cold included). Waterproof.
