The protagonist is a student attending a private school.
Somehow, many girls at this school already have lovers, which makes him constantly miserable.

However, he has one particular talent.
He is actually very good at sex.

He discovered his talent by mere chance when he assaulted a girl he'd known since childhood.

Thus, he came to this conclusion...

"Hey, perhaps there's nothing wrong with raping a girl as long as it satisfies her?"

Having awakened his talent, the protagonist begins to sleep with all the boyfriend-having girls he'd been admiring with bated breath and make them cum fiercely!
