家出少女・高邑緋雪の秘蜜 〜恥辱にまみれ快楽墜ちさせられていく彼女の純愛〜

あらすじ

One day, a girl in a school uniform came to the office of a salaryman, Watase, asking to stay over.

Her name was Takamura Hiyuki. Hiyuki's divorced mother has found a new boyfriend, but the boyfriend was abusive and tormenting her, so she came to rely on Watase, a distant relative.

Feeling that she has no one else to turn to, Watase reluctantly agrees to let her stay, despite the obvious risk if others find out that he's living with a schoolgirl.

As time passes, they grow closer, and Hiyuki develops strong feelings of love and gratitude towards Watase. However, she also feels a sense of guilt for relying on him so much.

At that time, she won a large amount of money from sugar dating and gave Watase a present for the first time. She couldn't forget the happy look on his face at that time, and she began to get more and more involved in sugar dating.

Then one day, she met Sakaide Homare, a self-proclaimed influencer who is the son of a rich man. A scumbag who is famous for ruining women sets his sights on Hiyuki, and upon noticing the relationship between Hiyuki and Watase, he comes up with a plan for a "game".
