Arriving at Kendra's sister's house but seeing the door open, the brother was curious to see and stumbled upon her taking a shower without locking the door of the room. It wouldn't have been a big deal if she hadn't done a very crazy thing: shaving her pubic hair. The razor had just touched the first hair when the brother outside the door shouted to stop it. Too surprised and embarrassed because her brother saw it, she could only quickly wrap the towel and explain to him. Because he was a sexually active person, he took this opportunity to use the excuse to punish her and the punishment was that the two of them had to commit incest with each other. It's the right person at the right time.
