My sister-in-law's sexual harassment and blackmail on WhatsApp leads to an erotic encounter

I was walking around the house when I saw my sister-in-law on her phone, sending naughty messages to some random guy on WhatsApp. I couldn't believe it! She was trying to get money from him by using her sexual favors. I knew I had to do something about it. So, I decided to confront her about it. I told her that if she kept doing this, I would tell my husband. She got scared and started begging me not to say anything. But I didn't want to let her off the hook that easily. I wanted to teach her a lesson. So, I made her get on her knees and beg for my forgiveness. Then, I took off her clothes and had my way with her. It was a wild ride, but it was worth it. Now, she knows not to mess with me again.
