JUL-558 Can't control Kanatani Uno's chubby body

A somewhat famous female chess player with a passion for challenging other masters. One time she received a challenging letter from an unknown person, the winning reward would be a large amount of money, but if you lose, you must agree to do what he asks. Of course she agreed. The day of the confrontation finally came, after a fierce battle, Kanatani Uno finally accepted defeat because of his subjectivity and arrogance. The conditions that the other guy gave were not too difficult to fulfill, as long as she was naked and obediently served, helping him satisfy his sexual needs, that was enough.
