I start out looking uncomfortable, like I'm trying to hide something under my dress. I ask you if I can show you my secret. You're astonished when you see my enormous dick popping out from underneath my dress! You've never seen a fat chick with such a big dick! I show you how hard it is to hide my huge cock. I can see your dick is getting hard so I ask you if you want to see more. I show you how I like to touch it, and tell you about the perils of having a huge dick. I eventually lube it up and use it on you! Now we have a secret :) you'd better hope I don't tell!
