Chisato Shoda, my stepmother, returned home drenched from an unexpected downpour. Her clothes clung tightly to her voluptuous figure, her lingerie completely soaked and transparent, revealing her ample curves. Losing all self-control, I couldn't resist and pulled her into my arms. With her parents away, it was just the two of us alone in the house. Her dripping wet body stirred something deep inside me, shattering the delicate boundary we'd always maintained. That rainy night, overwhelmed by desire, I could no longer hold back.
