Des:It turned out that Shiokawa Uni, who is No. 1 in the 2022 Masochist womens ranking, writhes in agony if you rough up her nipples, so we trained her to specialize in nipple torture. As expected, when I tied weights totaling 1 kg to her nipples and pistoned her from behind, she was in agony! As I continued to thrust deep into her throat, I pulled her as hard as I could, and she cried tears of joy.
