In a lavish hotel suite, Rei Kitajima, the seductive maid, is on duty. Her tight, revealing uniform leaves little to the imagination. As she tidies up, she notices signs of a recent tryst - rumpled sheets, a used condom. Intrigued, she slips a hand beneath her skirt, rubbing herself through her panties. Her touch grows bolder, fingers delving into her wetness, her breaths coming in ragged gasps. The room fills with her scent, her sounds, her desire, as she leaves her own mark on the room.
