"Yes, my tiny cum-slut. We will have to find a real cock for you to suck sometime. Tell me how much you would love that."
I didn't protest, or even stop to consider. "I would love that, mistress. I would make his cock big and hard for you to take it. Then after he was done with you, I would lick your juices off of him."
I was still pumping away inside her and this talk was helping me approach another orgasm. I was going faster, getting closer and closer to the edge when she suddenly screamed, "Pull out now! Now, slut! Get that tiny dick out of me!"
I was almost in tears as I followed instructions. I had wanted to finish inside her so badly. I still came, but it was a physical and emotional disappointment. After all the sex I'd had earlier today it was just a dribble of cum that fell on her pussy lips.
She laughed. "Seriously? That's all you can do? It's no wonder I'm finding other dick. You aren't going to cry about it, are you? Go ahead and cry, slut. This is why you're my little lesbian slut in your pink nightie."
I couldn't help it. The tears started flowing. I was physically enjoying the things we were doing, but all the humiliation topped off with a disappointing orgasm was too much. To make up for my shortcomings, I licked her pussy clean of my juices, and kept going until she came too. I was pleased that she came loudly.
Once her breathing returned to normal, she said, "Come back up here, sweetie. Let me comfort you."
She stroked my head as she hugged it to her breasts. I put both arms around her waist and hugged tightly. We were obviously not at the end of this journey, and for some reason, I could hardly wait for whatever would come next.
