BBAN-586 — Zero Romantic Experience. A Cheerful Younger Sister Teaches Her Shy, Unassuming Older Sister, Who Is Uncomfortable Around Men, About Sex. A Lesbian Sisters' First Sexual Experience. Yui Hina, Yura Kana

"Shall I help you practice kissing a guy properly, big sister? ///" My younger sister, who had come home from Tokyo after a long time, was more outgoing than me—and I'd always been a little envious of her. "Hey, big sister, do you have a boyfriend??" "Wow, big sister, you have big boobs, and if you changed your makeup, you'd be super popular." My shy and reserved older sister, Hina, is a plain, introverted girl who's not even good at talking to men, let alone romance. "I'll teach you everything, big sister—makeup, fashion... and sex too." Swept away by her younger sister's innocent smile, Hina shares her first kiss with her sister. Zero romantic experience. A lesbian sisters' sex swamp where a plain older sister who's bad with men is awakened to sex and pleasure! Yui and Hina's first lesbian work!
