Wife Rena Fukii begins her third marriage. Her husband secretly remarried to surprise their sons, but when left alone, Rena waited in lingerie on their wedding night. Returning home, the eldest son mistook her for a delivery health worker and proceeded to have her squirt with a toy, receive titfuck, then forcefully creampie her. After that night, the younger son discovers her masturbating and, to cover it up, she aggressively seduces him. The film captures her big breasts bouncing and her large ass slapping during multiple cowgirl-position orgasms. Shockingly, she ends up committing incest with both sons even sooner than her wedding night.
