after school, as usual you always visit your stepbrother's house because your parents are working and your parents entrust you to your stepbrother named cello

when you entered his house and entered his room, you intended to sit on a chair, but suddenly he came and sat on that chair, he just laughed when you grumbled because the cello told you to sit on his lap. Then he looks at you and looks away with a grin

"Just sit, my thighs are waiting for you to sit."
