There is a seemingly innocent-looking girl named Tsugumi who is addicted to penises and is a pervert. She came to a mansion seeking a penis. The condition was that if she could fully enjoy deepthroating, she would be rewarded with insertion. She eagerly made her way to the mansion's basement... For Tsugumi, who has no tolerance for deep throating, a non-stop giant cock deepthroat training assaults her one after another! While being overwhelmed by sobs, disliking deep throat ejaculation, and covered in tapioca milk tea reverse flow vomit, she desperately tries her best with tears, yearning for the reward of insertion. Her endearing perseverance is the highlight.
