JUR-149 Drugged by a bad friend with an aphrodisiac, she goes through repeated spasms, anguish, and overwhelming climaxes. His beloved mother, transformed into a beast. Oshima Yuka

Yuka lived alone with her son, and the two of them shared happy days together. Her son was shy but kind. One day, he brought home his friend Yano. Unlike her son, Yano had a somewhat flashy, carefree air about him, and Yuka wondered whether they were really close friends. Still, she found him surprisingly easy to talk to.

They all had dinner together, but after the meal, Yuka began to feel an unusual warmth and could no longer hold back, giving in to private self-pleasure. Yano, her son’s friend, secretly watched her from hiding.
