What Makes Me Hard?

I’m going to use your wetness to gently rub you. And once I’ve awoken all those wonderful nerve endings, I’ll apply just the slightest bit of pressure, letting your body tell me when it is ready to be entered. The harder you grind and the wetter you become, my thumb is naturally drawn inside, making you cum so hard I can feel your muscles spasm on my cock.
