Niizuma Ketsuman Training

The Niizuma Ketsuman Training Onahole (male masturbator) embodies the tight entrance of a back hole! The Ketsuman Ring is a ring developed exclusively for this Onahole, and was made to reproduce the feeling of real tightness and insertion. By placing this ring, you can get closer to the unique feeling of insertion and tightness from behind, and experience the feeling of doggy style. Furthermore, we researched the gimmick of the grooves inside the Onahole, and reproduced the erotic feeling of being pulled by the continuous grooves, from the smooth acceptance feeling to the erotic feeling of being pulled by the continuous grooves. In the end, this feels the best! The continuous grooves from the entrance will melt your body and mind.
