[Sister Mytory (Miginohito Mitsuru)] Submission! Loser senpai gets trained! [QuarantineScans]

A dominant schoolgirl takes control of a hapless senpai, turning his desires against him in a game of power and submission. Bound by a collar and leash, the male subject finds himself at the mercy of her playful yet firm training, where every sensation is controlled to keep him on the brink. As she teases and dominates, the tension rises between the strict authority of her gaze and his desperate need for release, forcing him to choose between his pride and his surrender.
