Akiho Ishibashi, seeking solace, finds herself drawn to the dimly lit stairway. She begins to undress, her silken skin glistening with sweat as she ascends each step. Her fingers dance along her inner thighs, teasing her wet slit, as she leans against the cool wall. Each stair she climbs brings new heights of pleasure, her moans echoing in the empty staircase. She reaches the top, her body trembling, her orgasm washing over her like a waterfall.
