LULU-433 She taught her shut-in, introverted, nerdy, big-assed, J-pop idol-type younger sister how to do lewd masturbation poses, then immediately reformed her into a submissive, squirting sex doll through piston-like thrusting. - Hinako Matsui

When I first met her younger sister, she turned out to be a shut-in, introverted, NEET girl. Wanting to admire her defenseless big ass with zero caution, I paid her and had her strike a cock-flirting pose. Unable to resist her incredibly arousing position that emphasized her pussy lips, I thrust my dick straight into her slit! I made her cum over and over again with rapid-fire thrusts, giving her no choice but to cum! I transformed the arrogant, cocky otaku little sister into an obedient slutty sex toy and cummed inside her countless times!
