It turned out that Untan Shiokawa, the No. 1 M woman ranking in 2022, writhes when she applies violence to her nipples, so she tried training specializing in nipple torture. Sure enough, when a total of 1 kg of weight is tied to the nipple and pistoned from the back, it is super agony! When I pulled it so hard that it seemed to tear off and continued to thrust it in the back of my throat, I shed tears of emotion and was happy.
