Ruka Kisaragi, an alias used by a 22-year-old wife, and her 40-year-old husband are an age-gap couple who enjoy filming their sex life. Eager to show off the wife he adores, the husband sends in one of their very explicit homemade videos, and the pair are interviewed about their close relationship. They say they always have sex, sometimes several times in one day. Ruka first gives a rare masturbation performance and gets incredibly wet. During sex, her dominant husband repeatedly makes her suck him and asks how she likes her own taste. Their affectionate but clearly dominant-and-submissive chemistry is the heart of the footage.
