Everyone loves beautiful women's panties. Brand new ones or ones that have been washed and smell like soap have no value. A man's romance is filled with the dirty and smelly underwear that has been spent half a day, or even more, sleeping, eating, and using the toilet with a beautiful woman. This work focuses on the panties of the neat and Yuki Yukine. She wears them the day before, and the lewd stains that have been left on them from erotic acts and humiliating play. Her shy smile stimulates the man's groin. It's just cloth, but it's still cloth. A gift for underwear enthusiasts.
