Tenga Crystal Masturbator
It's almost a shame to use it for masturbation!
The masturbator is transparent and has a stimulating texture inside the canal that intensely stimulates the penis. A further level of stimulation can be created by squeezing the sides because this adds more pressure to the 3D elements and can lead to explosive orgasms.
The masturbator is also easy to clean after use. Not only does the drying stand mean that it can dry quickly and in a hygienic way, but it also means that the masturbator can be put on display as well.
