Sleepless ~A Midsummer Night's Dream~ / 眠れぬ〜真夏の夜の夢

A Western-style building that stands quietly in the mountains, the Black Rose Museum ...
Ryohei Takamiya, a university student who will stay there for a week as a tutor, triumphantly visits the museum.
There lived three women in the hall: Marie Mamiya, a bewitching mature woman, her daughter Maria, and the maid Aira who serves her hall.

Takamiya, who was entrusted with the tutor of Maria, a beautiful and selfish girl, is invited by them one after another to be tempted by nasty temptations while spending time in the hall.
And while being tossed by three sexually hungry women, the gears of fate are gradually derailed in the days of drowning in pleasure with them ...

What lies ahead is a rosy future or a nightmare reality ...
The door of the Black Rose Museum is now open ...
