The simple setup of tutor Yui Hatano gently guiding a male student suffering from premature ejaculation is incredibly erotic! The busty, sexy, and kind teacher hesitantly asks 'Is it okay with an aunt?' in a sweet tone, stimulating his penis for premature ejaculation improvement play. Excited by his penis not going soft even after ejaculation, it escalates to practical sex guidance. The hot scenes of repeated creampies had me glued to the screen. The cast, including Yui Hatano, Sayuri Hayama, and Yuki Yoshizawa, all have large breasts and no misses. The simple style highlights the essence of eros, making it endlessly rewatchable. The blend of the teacher's kindness and erotic guidance is packed with charm that captivates the innocent boy.
