In a compact, steam-filled shower, a Japanese couple finds solace in each other's arms, their bodies slick with water. The woman's delicate hands soap her lover's muscular frame, tracing the lines of his tattoos, while he returns the favor, his fingers lingering on her sensitive spots. Their breath hitches as they press against each other, their hips moving in a rhythm as old as time. The shower head rains down on them, its pulsating spray echoing the rhythm of their lovemaking.
