[RKI-088] Older sister is a virgin, younger sister is a slut ~Real sisters~ (Censored)

These sisters have cute smiles and are very close. The slutty younger sister, who has had sex with over 90 people, teaches her naive and virgin older sister the pleasure of sex and they synchronize! This is a work that is full of charm in every way, from the shyness that only sisters can have, to the naive sex of losing one's virginity, to the FUCK that makes them squirt and cum!
