BBAN-586 · Zero Romance Experience. An Extroverted Younger Sister Teaches Sex to Her Plain, Male-Shy Older Sister. First-Time Sister Lesbian Sex. Hina Yui & Kana Yura

"Let me help you practice so you can kiss guys better... okay? ///"
My younger sister, returning from Tokyo after a long time, is the opposite of me—she's active and outgoing. I've always been a little envious of her.
"Hey, big sister, do you have a boyfriend??"
"Huh~ you have big boobs, and if you changed your makeup, you'd be super popular."
The older sister, Hina, is shy and socially awkward, a plain introvert who is bad at everything from romance to even talking to men.
"I'll teach you everything... makeup, fashion... and even sex."
Swept away by her sister's innocent smile, Hina shares her first kiss with her.
Zero romance experience. A lesbian sister sex session that awakens a plain older sister who is bad with men to the world of sex and pleasure! Hina Yui's first lesbian work!
