Holly's Folly, Part 2 (Patreon)

Holly and her sister Skylar have been getting picked on by their mama since they were kids. Holly less so, because she's... well, she's Holly. 

Big chested, pretty faced, not-quite-bright but certainly more palatable in the eyes of her mother than big dumpy "smartass" Skylar.  One day, Holly decides that she can help her sister in the way that nobody else can - by taking some of the heat off of her until she can graduate. 

And the best way to do that is to put on some weight.  Yeah, it's a dumb plan. 

Holly's kind of a dumb gal. As you can probably guess, it very quickly spirals out of control.
