Bestvibe 10-Speed Manual&Electric Masturbation Cup with Penis Ring

Description:

Like a huge black butterfly with its body curled up and wings folded, it can be easily controlled by one hand. 4 ridges line on the outer side of the wings, adding beauty and special grip. The inner side is also arranged with a circle of threads to increase the roughness.
In this case, your penis will get more pleasure from thrusting. Due to the softness and mobility of the wings, this toy can accommodate dicks of most sizes. 

Before you start enjoying, please place the cock ring correctly on the base of the penis, the meaning of whose existence is to improve the erection of the penis and premature ejaculation, and to extend the time of pleasure-enjoying. Then just shove your dick into the cup and adjust the vibration frequency among the 10 vibrating speeds according to your mood.
The pleasure can be promoted by increasing the squeezing against the outer wings and manually moving the cup back and forth.
What's more, it is waterproof and USB rechargeable.
