Watching people live in ancient China during the Tang Dynasty

Watching people live in ancient China during the Tang Dynasty. A wealthy young woman with no make-up or hair pinned down is taking a shower, carrying a box of soap in the bathroom. She is soaking in the bathtub of the mansion. As she stands up, a young man walks into the bathtub and hugs the young woman whose clothes have been removed, leaving her completely naked. The two of them start kissing, sucking, and tasting each other's sweet lips.
