A fair-skinned young married woman with translucent skin goes on a hot spring trip with her first affair partner. Still not fully grasping the reality of their infidelity, she innocently places the man's underwear into her small mouth with a pure smile. She hesitates slightly at his massive cock, too large to fit, and a trace of anxiety flickers in her eyes. Worried someone might walk in, she obediently stimulates her own clitoris as instructed, growing increasingly sensitive. The sound of water fills the air as the man thrusts his shaft deep inside her. Gradually, she begins swaying her hips, surrendering her body completely as she moans passionately. That fleeting moment of release marks the end of her first forbidden affair.
