HBAD-198 Fucking my sister-in-law feels so good

Because he was preparing for the university entrance exam, his younger brother was invited by his older brother's family to live with him to facilitate exam preparation and travel. Here, he was cared for very thoughtfully and enthusiastically by his sister-in-law Hatano, but because of this, both of them gradually developed feelings for each other. The times when the husband goes to work are also the times when secret love affairs happen between them. The only crime is that the husband still works hard every day to earn money to take care of his wife and younger brother without knowing that they both have a huge horn stuck on his head.
