[antyuumosaku (malcorond)] Meikkousei na Syoujo no Ehon [SquigglesJP]

Miho is a grinning, big-breasted schoolgirl who turns a first date with her shy uncle into a hotel-room lesson he never saw coming. Teasing him for planning to bang her from the very start, she coaxes the blushing virgin through a sloppy first blowjob before climbing on top, riding him until he cums deep inside her again and again while she insists it still isn't enough practice. Between her playful taunts and his overwhelmed gasping, this eager niece makes sure her uncle properly graduates from amateur virgin, one nakadashi at a time.
