[Bernin] Chubby Onee-san's Shrinking Experiment [Full Color]

A voluptuous, dominant onee‑san discovers a tiny, shy miniguy and invites him into her secret laboratory. She implants a remote‑controlled needle on his collar and administers a destabilizing drug that forces his body to shrink, turning his once‑normal form into a miniature plaything under her massive, femdom control. As his shrinking intensifies, she revels in the power dynamic, promising repeated pleasure once the medicine fades, leaving the audience eager for the next twist.
