Online Lessons Turn Into Sex Session!

I signed up for an online drawing class. It's supposed to be about drawing naked women. I sat down in the living room with my drawing utensils and started the online lecture just in time for class. But you only have nonsense in your head. Instead of letting me draw, you color on my body with the colored wet brush. Now that my sweater is dirty, I take it off and want to continue drawing in my underwear and follow the lessons. You distract me by continuing to draw on my half-naked body. The wet color drips over my skinny body. I notice how horny you are. Then now I have an idea. If you want to color then draw me. I pose for you as your naked model and you can draw me. But your fingers don't stay on the piece of paper. You like my body more and it is getting dirty. I'm already quite colorful. Now it's your turn to get your penis out of your pants. I colored with the brush on your stiff penis....
