A nurse, her body glistening with sweat and water, lets out a soft moan as her hands roam over her generous curves. The onsen's steamy atmosphere has her inhibitions at a low, and she's taken over by her desires. She pinches her nipples, feeling the electricity shoot straight to her core. She slides a hand between her thighs, finding her clit already engorged and ready. She rubs herself, her moans echoing in the tiled room, when she suddenly freezes, sensing a presence. She's not alone, and the thought sends a shiver down her spine, fueling her lust.
