That bitch Sylvia just never learns! She owed me $20 so I confronted her when we were sunbathing. Making a huge mistake, she denied it and called me a bitch, plus I had to get even with her. I got on her down on her back and sat right on her belly. She yelled at me to get off but instead I pinned her arms with my knees. Now that I had her full attention, I bitched her out for not paying. I’d sit upright and shift my weight around to have the maximum impact on her stomach. I could tell that she was really struggling with ass sinking into her stomach. I love feeling her uselessly squirm beneath me!
