:The Succubus Fantasies:

"Take them off and keep eating!" you tell your sister. Neither of you need much encouragement, your outer clothes are uncomfortable now, but the pull of the food is too strong to stop.

Your sister starts to unbutton her shirt. Some of the buttons pop off before she gets a chance to undo them. She breathes a sigh of relief and unclips the bra over which her breasts now spilled out. Wiggling out of her skirt, she struggles to pull it down over her expanded hips, but inch by inch she manages. She strips off her panties and smiles at you, naked. Her figure is now full, rounded and glorious. Melon-sized boobs sit resting on a large round stomach. Her arms and thighs bulge out, her face is rounder than it was before, but that doesn't stop her being undeniably pretty.

You do the same, stripping off your tight shirt that seemed to fit fine a moment before, and popping open the button of your shorts before squeezing them down your rotund lower half. You pull down your pants and look down at your own fattened body. It's certainly obese, but you don't feel unhealthy or self conscious. Whatever charm or magic that is going on with this food is bound to be reversible. East come, easy go. And for now, currently the weight is definitely coming.

Your sister also pauses to assess her new size. "I so fat. Do you think I'm disgusting?"
