BBAN-586 Yui Hina, Yura Kana - Zero romantic experience. The outgoing younger sister teaches sex to her plain older sister who’s bad with me

The younger sister, who is more outgoing than her older sister and has always been a little envied, returns home from Tokyo after a long time. She offers to help her older sister practice kissing so she can get better with men. The older sister, Hina, is shy and reclusive, with no romantic experience and difficulty even talking to men. The younger sister, noticing Hina's large breasts and suggesting a change in makeup could make her popular, offers to teach her everything about makeup, fashion, and even sex. Swayed by her sister's innocent smile, Hina shares her first kiss with her. This is a story of a lesbian awakening, as the younger sister introduces her inexperienced, man-shy older sister to sex and pleasure.
