Brunette in hot tub gets playful

A brunette is sitting in a big, round hot tub, water bubbling around her. She’s not wearing anything, legs spread wide, looking down with a surprised or playful expression. The tub is white, and the walls behind her are tiled. The lighting is bright, making the water look clear and the scene feel open. She’s alone in the tub, and the mood feels relaxed but charged. There’s a small purple toy on the edge of the tub. The whole thing feels casual, like she’s just relaxing and something unexpected is about to happen. No one else is in the room, and the focus is entirely on her and the water swirling around her legs.
