Ebina Tsukushi was just a normal high school guy who didn't stand out in his class at all.
He wished that - despite being distanced from his childhood friend Fujikawa Himawari - he would have hope for his love life in the future.
But even when he tried inviting her to walk together from school, she only told him that "It would be embarrassing if there was rumors spread about us being close," slightly crumbling his heart. Even when he confessed to her, he got utterly shot down and became very depressed.

However, on that same day he got rejected, his very confident and popular older sister Nadeshiko, who had been studying abroad, returned home!
Wanting to be as confident as she was and live a fulfilling high school life, Nadeshiko, who was also huge brocon, just told him: "Leave it all to me!" A couple of days later, he found out that she had planned something up together with the school's haraguro nurse, Ayame --

With the power of his big and powerful cock, he would conquer the hearts of his schoolmates (including a teacher's) and create himself a harem. With the help of both Nadeshiko and Ayame, Tsukushi's unexpected harem life began!

Weakness: Being kissed gently. Gets turned on especially when her partner gently whispers in her ear while kissing her.

The school's nurse with a very haraguro personality. She is the daughter of the previous principal who had managed to build a harem around him, and a child of one of the women in his harem. It's implied that Ayame has also had sex with her sisters. She wants to recreate the feeling of family she had being raised in her father's harem.

Because she is knowledgeable (as well as her body is) about sex, she likes teasing others about it and just playing with others' minds.

Since she has always been treated in a "special" way because of her position, Ayame has never experienced what it feels like to be gently kissed, and deep inside her wishes to be kissed like that.

"You need to have more faith in your dick's potential and power."

Since Nadeshiko has returned to school, Suzuran has been losing popularity and in an effort to spite her, she tries to make Tsukushi her pet by seducing him.
