My city-dwelling niece (Mina) returned home to the countryside after a long absence, and I was shocked. She'd transformed into a flashy J-style gyaru, her body now voluptuous and mature. Arrogant and lazy, she mocked me as a useless NEET, bragging, "In the city, I get allowance from sugar daddies!" while showing off her gonzo sex videos. Though teased by this bratty girl, I gave in to pleasure—how dare she look down on adults? I'll make her sassy pussy understand!
