Elegant first-time spa guest Mai Seta has her erogenous zones stimulated without warning by the esthetician. Wearing only revealing underwear, she is coated in lotion, has her breasts massaged, and soon finds fingers sliding inside her. Her body responds until she can no longer suppress her moans. When the esthetician fucks her from behind on all fours, the pleasure takes over and she climbs on top to ride him herself, exposing a lustful side hidden beneath her refined image.
