I always have a thing for bondage. When my sister's friend came over, I took the opportunity to show her the ropes. I started by blindfolding her, making her feel helpless and vulnerable. Then, I bound her hands and legs, leaving her at my mercy. I teased her, running my hands over her body, feeling her shudder under my touch. I took my time, enjoying the power I had over her. I could do anything I wanted to her and she couldn't do a thing to stop me. I was rough with her, showing her just how much I enjoyed this. She squirmed and moaned, but I didn't let up. I pushed her limits, taking her to places she never thought she could go. By the end, we were both breathless, spent. It was a perfect way to spend an afternoon.
