DASS-161 I’ll make that little sister who provokes me with a worthless dick understand with my penis. Natsu Tojo

Unpopular college student Akira gets a new sister-in-law, Natsu, when her parents remarry. Natsu has a foul mouth, but in front of her parents, she was a serious and cute girl. She thoroughly incites her brother, saying, “You’re not popular with your brother.” She is irritated by such an attitude and she attacks Natsu.
