They press their lips together violently and intertwine their tongues, not caring that their saliva mixes. The relationship between the two, who are completely absorbed in sex, is the senior's wife and the senior's junior...a secret relationship that must never be revealed. My senior's wife, Nanami, has a good relationship with her senior, Kota, and her senior's junior, Shinichi, is also married and living a happy life. The two have excellent physical compatibility and have no intention of stopping their relationship.
