Featuring incredible suction, an insanely realistic interior texture and a completely discreet casing that makes for fantastic portability, the Perfect Stroke is a patent-perfected male pleasure tool set to work its magic on both erect and flaccid penises. Inside a curvy, comfortably held plastic chamber, an excitingly lifelike mouth waits to suck- the unique Accumulation Technology activates when the chamber is squeezed, external pressure creates a natural inner vacuum that really does suck the penis in, pull the stroker back down and the process repeats. Needless to say, the Perfect Stroke is a great tool for men who sometimes have trouble achieving erection, as the patented suction effect helps draw blood into the penis. Of a soft TPR material along with ABS plastic, the Perfect Stroke cleans easily with warm soapy water- remove the sleeve for a thorough wash. Compatible with water based lubricants.
