[Pop Machine-gun (Kaho Ren)] Boyish no Ane ni Renshuudai to Shite Shiborareta

An eager, pixie‑cut sister, eager to dominate, forces her brother onto a bed where she uses her ample, soft breasts as a training dummy, teasing him with relentless pressure and wet, slick sounds. The brother gasps, overwhelmed by the intensity, while the sister revels in her control, declaring she’ll squeeze him dry again despite his desperate pleas. Their intimate, incestuous encounter escalates with rough, forceful actions, culminating in a climactic, breathless finish.
