Christina, her body glistening under the shower's pulsating spray, indulges in a secret moment of self-pleasure. Her fingers trace the contours of her breasts, pinching her hardened nipples, as her mind wanders to a taboo liaison. She leans against the cool tiles, her other hand venturing between her thighs, parting her slick folds. Her breath hitches as she imagines a stranger's touch, her body responding with a surge of wetness.
