KISTOY Martin vibration lock ring

KISTOY Martin vibration lock ring（FM052）

Physically locked

By locking the ring tightly, the blood circulation speed is reduced physically, which can reduce the sensitivity of sensitive parts during passion and make the male charm bloom for a longer time.

Tentacles tease soft and comfortable  

The special soft rubber tentacles can gently tease the vagina. While the sperm lock ring squeezes the base of the male lover, the massage point continues to vibrate and stimulate the female vagina to reach a double climax.
