[Choukasha Doujin (Nakamura Rohane)] Gyakuen ～A Devilish Little Kouhai Plays with Fire～ [ShinyTL]

Sayoko, a devilish kouhai with a crescent-moon choker and a phone full of embarrassing pics, has her flustered virgin senpai Sakai exactly where she wants him — teased breathless, locked up, and squirming under her every touch. Between head pats, 'good boy' praise, and kisses that leave him humiliated and aching, she dangles a cruel wager: survive until the Empress Hunting Ground event without masturbating even once, and she'll delete everything. Calling him her little puppy while he wonders how she keeps finding weakpoints he never knew he had, Sayoko turns every nibble and whisper into a game of fire only she knows how to play.
