Dream Machine/Cynthia/Return
You hadn't expected to pay fat Cynthia a return visit, but there is something about her that makes you want more.
This time, she is laying on top of the covers of her bed, completely naked. Her mouth is open and she is making snoring, snuffling noises. You can see a dribble of spunk leaking out of her cunt into a wet patch. There is what you guess to be dried jizz in her hair as well. Pretty obviously she has just been fucked.
Without any preliminaries you push her knees up, kneel in place and bury your cock into her well-used spunk filled cunt. After a few strokes you pull out and sit back on your heels. She hasn't even woken up. "I wish I had a bigger cock," you think, and to your surprise, it grows another inch longer and wider too. "Wow!" you think. "I didn't know I can do that."
This time you get a reaction as you push in, but it still feels loose. "Bigger still," you think, and you feel it swell up inside her.
"Uh... Uncle Peter," she mumbles and her chubby legs reach around your ass. Your cock must be a good eight inches long and an inch across now, but she can still take it all inside her six-year-old body.
"Make it thicker," you think and now it's being tightly gripped.
"Wha! You're not Uncle Peter," she says as her eyes open wide and she sees that instead of a full grown man, it's a boy with a massive cock on top of her.
The sensation of her spunky cunt gripping your cock and the sight of her fat belly wobbling about as you thrust into her is getting you off. "Thicker," you think and the look on her face changes from lust to shock as you stretch her beyond anything she has experienced before. Your balls begin to tighten and as you start to cum, you add one final thought. "Lots and lots of spunk."
As it starts to pump, you see her belly swelling and realise that with her cunt firmly plugged the jizz has nowhere else to go but into her immature womb. Afraid that you might damage her, you pull out, still pumping and shooting sticky white goo over her body. When it begins to tail off, you shuffle forward, sit on her chest, and shove your wilting cock into her mouth.
"Thinner," you think and you are able to force your now long slim cock down the six year old's throat, filling her belly with the last of your copious spunk.
