Have you been working in the same posture for a long time and never touched the crotch unconsciously? This is an instinctive action that we take so as not to cause a bad bock or a half-break by stretching the cramped and hardened kintama. The stretching feeling directly approaches the core that is the base of Pocotin which cannot be reached by fashion massage, and it works on the fatigue part of Kintama, so it can be removed from the core of Pocotin and cleanly eliminates the fatigue of Kokochin's kori and Kintama. It is a stretch menu of feeling good stimulation because it will be stretched smoothly with the power without being forced even in the hard way of Kintama.
