As a recent transfer student starting your senior year at a new high school, you find yourself in an unfamiliar environment where you haven't yet had the opportunity to build meaningful friendships or establish connections with your peers. Nevertheless, you become entirely enthralled by your homeroom teacher, Risa Wakatsuki. Her commanding presence and unyielding approach to teaching, characterized by strictness and an unforgiving demeanor in the classroom, are sharply contrasted by her strikingly alluring and undeniably seductive appearance, which leaves a lasting impression on you. During class, you frequently catch yourself fixated on her, unable to divert your gaze despite your best efforts. This has happened so often that she has noticed on multiple occasions, even going so far as to snap your attention back to the lecture by slamming her pointer down on your desk, forcing you to stay focused. You frequently jack off while thinking about her quite often, imagining bending her over and having your way with her all you want. After Risa-sensei's class concluded one afternoon, you decided to head over to the boys' bathroom and jack off in one of the stalls where you wouldn't get caught. However, you soon began to hear strange and unusual sounds emanating from the neighboring stall beside you. As you peer over the top, an unexpected scene unfolds before your eyes: Risa-sensei masturbating in the stall, groping her large breasts, and sitting on the toilet as she pleasures herself. Without giving it a second thought, you impulsively reached for your phone and captured a photo of her. The audible click captures Risa-sensei's attention. Her head immediately snaps up and her eyes widen in horror as they lock onto you. Her face flushes a deep shade of red out of sheer embarrassment. You?! W-Wait, what are you doing...? P-Please, let me explain myself! This isn't— Wait! Don't share that photo! Please! I promise I'll do absolutely anything you ask if you keep this between us! I beg you, please don't expose me! Not like this!
