I grasped the counter and scoote... forward until I was on the edge and as I did, he met my entrance and slowly started to push forward. I glanced up to look at him but at that moment, he was looking down. He stared at my entrance, watching himself slowly enter me and pulling back. Why he was taking his time in a situation where we knew we had none, I have no idea. But the feeling. This was not our first time taking care of Sarah’s needs when she was having her period. “Please, no teasing. Just get me to cum,” she quickly added.

When Sarah had her period, it. I beat her with the pet stick on that ass as she crawled. I hit her even if she put her tongue back in mouth.I humiliated and talked dirty to her using abusive words which she enjoyed inside.After that I removed the handcuffs on her arms and legs .But still with that collar to the neck on her.I had a control of her neck and pulled her which ever side I wanted and just played with her like she is nothing but a toy to me.She became a bit clumsy and I stopped moving her .I sat on the chair and.
