This is the fourth work featuring 22-year-old, I-cup beauty Yuu Sasamoto (pseudonym), who is set to marry in a few months. While her fiance is away at work for seven hours, she has a 5-person orgy at her home with local men she found online. This takes place in her cherished family home, where her grandparents also reside. Four penises successively enter Yuu's vagina, ultimately sullying the couple's love nest with copious amounts of precum and semen.
