The brother is giving Kaede advice on her love life. She can't sleep at night because she likes a guy from the same club. The brother goes to the convenience store to get some food, asking if she's hungry. When he comes back, his sister is asleep. He can't help but look at her panties under her uniform, and touch her body a little, and suddenly, she gives him a deep kiss. I think I like you, brother! I've fallen in love with you, not with our classmate! You told me to be more proactive, didn't you? I'm going to be more proactive from now on! And she gives him a blowjob. She makes him lick her pussy and cums. She inserts it raw herself, and when her brother tries to pull it out, she locks him in a crab position and doesn't let him get away!
