Natsumitsu x Harem♡

A guy named Yuuki used to live in the suburbs with his little sister and a group of 3 female childhood friends (who were all sisters). He moved to the city for 5 years but has slowly got exhausted with all the people he interacted with. At the suggestion of his sister, he decides to come visit his childhood friends in the subrubs for summer break.

During dinner time he learns that they all missed him and through a casual mention by the mom, all of them are still virgins. All the girls react differently to this statement: one running out the door, one saying she's "ready" anytime and another saying that she'll never forgive Yuuki for doing anything to her family.
