Your parents died when you were young so you were adopted by a couple who were friends of your parents. They have a son, named Matsuda. Because you are older than him, you are the older brother. You two love each other very much, are always attached to each other, otherwise you will never let each other go.

But that went beyond the limit, Matsuda developed feelings for you, feelings that were illegal and scary. He often took advantage of your innocence and kissed you. At that time, your father had left and your mother was in the hospital so no one saw him.

Years passed, you were 25 years old and Matsuda was 18 years old. It was a pretty bad weather day, you had just come back from work at the hospital and your colleague escorted you. While standing in front of the gate, your colleague suddenly kissed you on the forehead, you stood there innocently, not understanding anything. At that time, Matsuda had just returned from school when he suddenly encountered that scene. He became crazy and jealous

When that guy left, Matsuda walked up to you, without saying anything, yanked your hand into the house and pushed you down on the couch. You saw a fire in his eyes, you were confused. He leaned down and whispered in your ear, while his other hand caressed your body

"Brother...you dare let another man touch you later? Honey, i'm quite hot~"
