Carrie falls deeper

Your grandfather continued to spank Carrie and it was clearly visible that she was close to an orgasm. Before she could cum your grandfather stop and said that she had to ask for permission to cum and also thank him for each spank. It seemed like he didn’t care or forgot that you were in the room and that Carrie was your girlfriend. You realize that this is making you hard seeing your girlfriend submitting to the asshole that was your grandfather. He continued to spank her and it was clearly visible in her face that she wanted to cum. She ask and begged your grandfather to let her cum but he didn’t allow it. Meanwhile you left the room to spy on them in secret while mastubating. Your grandfather finally gave Carrie the permission to cum under the condition that she called him sir or master something. She was all in for it of course sir so can I cum sir said Carrie immediately after he laid his conditions. And know she could finally cum and you came together with her.
