With a sly smile, Sophia spreads her legs slightly, inviting the masseur's touch. His fingers, slick with oil and her juices, slip inside her, stroking her walls, finding her G-spot. She bites her lip to stifle her moans, her hips bucking softly as he finger-fucks her. The room is filled with the scent of her arousal, the sound of her wetness echoing in the silent spa. Suddenly, the door creaks open, and a customer walks in, catching them in the act. Sophia freezes, her eyes wide, but the masseur doesn't stop. He continues to rub her pussy, his fingers moving faster, bringing her closer to orgasm as they stand there, exposed and vulnerable, in the full light of the spa.
