Beautiful girl and college cheerleader Azusa Misaki, on a senior's advice, asks university alum Hana Kano for training guidance. Hana sharply criticizes Azusa's lack of sex appeal, then gradually begins teasing her body as Azusa stands shocked. With a wicked smile, Hana slips her hand into Azusa's underwear and slowly entwines her snake-like tongue, tormenting Azusa's pink nipples. This intense lesson marks the beginning of unlocking Azusa's virgin lesbian desires.
