The roommates in the share house where protagonist Sota lives are none other than three succubus sisters—!
The eldest sister, Misa, is the doting type.
The second sister, Rin, is cool and quiet.
The youngest sister, Mei, has a masochistic streak.
Sota, assigned as the cook (!?), gets milked dry by the three girls every day.
But during Golden Week, Misa and Mei go on a trip, leaving him alone with Rin.
Lynn, who had secretly been interested in Sota all along, invites him to have sex out of curiosity.
With the irresistible Lynn making the first move, he couldn't possibly refuse, and their holiday of nonstop sex began...!
Then, on the final day of Golden Week.
Misa and Mei return home and crash the party, escalating things into an even bigger orgy—!
