As a respected older sister, Hinata Natsumi is a completely submissive M-type pet in front of me. A hot spring training camp where she's manipulated and played with in a 180-degree reversal of roles. (CAWD-722)

'Sister Xia' is called 'senpai' (senior). She's a senior who's proud and considerate, but no one knows her introverted side. She's a submissive, obedient masochist, but her attitude completely changes when you're alone with her. She becomes a woman. During the trip, she immediately performed deep throat oral sex upon entering the hotel, ejaculating once and then it was over. There were no other activities; I simply pretended to be sick and arranged for myself to be alone with Sister Xia, engaging in BDSM sex until Nakama returned. In the men's bathroom, she wore a transparent uniform and had sex with me fully clothed. The teacher and Nakama were both drunk, and I made her endure the noise while engaging in stimulating and immoral sex. In any case, she would never refuse me. My personal masochistic pet.
