My balls are already empty... I'm an unpopular guy who lost my virginity to a sex-crazed plain Jane childhood friend who used me as a substitute vibrator, Yui Hina
Returning to my hometown to seek local employment, I reunite with my childhood friend, Hina-chan, who is now older than me. She has become a reclusive, lonely woman, wearing loose clothing, eating sweet snacks while watching live streams, living a decadent, idle life. When I visited her room on the day we met again, I caught her masturbating alone. From that day on, I became her substitute for a vibrator, repeatedly used to relieve her sexually charged body.
