Tied up by her wrists, Maimi Tokiwa offers herself to Akari Niimura, whose natural S-side has exploded! While training Tokiwa in her first lesbian experience with harsh words and caresses, she exposes her deviant nature... As punishment for squirting uncontrollably during handjobs, Tokiwa gets slapped on her pussy, her nipples hardening as she becomes completely infatuated with Niimura! With each orgasm, her body convulses as she loses herself in pleasure, and she begins to accept the training for her transformation into a bitch. Encouraged by Niimura's genuine advances, Tokiwa licks Niimura's entire body, even her toes! She sucks Niimura's pussy while simultaneously licking her anus, and manages to climax even while being pinned down and suffocated by Niimura's ass. Through Niimura's training, Tokiwa starts to enjoy her first lesbian experience, riding the highs and lows like a seesaw. Like a naive child, she entrusts her body without reservation, and as they reach orgasm after orgasm, the distance between them shrinks. In the end, they share the most intense and erotic time, dominating each other's bodies and minds with pain and pleasure.
