Momoka, the sultry office executive, slips into the restroom after a long day, still in her suit. She notices her pantyhose, damp with sweat, and decides to remove them for some relief.

She leans against the wall, her breath quickening as she pleasures herself, her mind filled with taboo thoughts.
