LULU-420 - Newlywed husband, excessive lingering feelings leading to a break-in, sexual activity involving arousal marking with ejaculation, resulting in being soaked in urine, unstable mental state, large-buttocks lover, Tenma Yui.

I had a lover with a large buttocks and strong jealousy who was mentally unstable until a few months ago. I had been secretly dating her before marriage, but her presence became too much, so we broke up. I thought she agreed to the breakup, but one day, horrifyingly, my lover moved in next door to my house. And suddenly, the lover came to my house and marked the entire interior with arousal markings, covering it in urine...! The furniture I chose with my wife and the commemorative wedding photos were all soaked! From that day on, avoiding my wife's eyes, she would sneak into the house and meticulously mark even my genitals with incontinence.
