Super-stretchy Senso Plus masturbator is hygienically superior. 3 chambers for graduated, increasing tightness! The deeper the penetration, the tighter it gets! Phthalate free.
This is made of some type of super soft, super stretchy rubber, but it is so soft and stretchy that I didn't really feel anything. I found that turning the thing inside out works better, but still I don't think it's worth the money.
