Animate this high-quality anime style scene, maintaining the exact still image composition: [Core Animation: Physical Connection] The man behind Riko performs a steady, deep rhythmic thrusting motion (vaginal penetration). The visual focus is on the subtle back-and-forth movement of their hips and the point of intimate contact. [Riko's Expression & Subtle Reactions] Riko's dazed and intoxicated flushed face remains largely stable, but her teary eyes show very subtle blinks and slight changes in focus. Her slightly parted lips occasionally release faint, steamy white breaths. Her body shows very subtle, almost imperceptible trembling with pleasure. [Man's Interaction] The man's slender hands are firmly gripping and subtly moving on Riko's hips, emphasizing the rhythmic action. [Environment & Atmosphere] The overall steamy atmosphere of the laundromat is drifting slowly across the frame. Soft cinematic fluorescent lights flicker very subtly, creating gentle, dynamic shadows. [Technical] Smooth 2D animation, high frame rate, focus on the stability of the characters and the core rhythmic action.
