Utimi Vacuum Penis Enlargement with Erection and Postpone Ejaculation Shrink-ring

This style of vacuum masturbation cup is made for male's penis enlargement. Like many other masturbation cups in our store, this product works via vacuum pumping to increase the penis' pressure. As a result, in the condition of vacuum pressure, the sponge cells will expand. However, what makes this one different from others is the shrink-ring entry in shape of female's vulva, soft, elastica and comfortable. Good Quality and Manual Control!
