[Contamination (eigetu)] My Little Brother's Girlfriend

When her little brother's girlfriend Yukina shyly asks Ayaka for advice about sex, it seems like an innocent heart-to-heart—until the silver-haired cutie pulls out a cock 'made to destroy girls' and coaxes her boyfriend's sister into stroking it. One overwhelming load later, the sweet girlfriend has Ayaka pinned and pounding, vowing to keep claiming her until she's addicted while admitting her victims stay silent because they're hooked on futanari seed. Sweaty, relentless and dripping with nakadashi, this netorare turnabout turns the doting girlfriend into the family's secret apex predator.
