Susan and Mary test chef hat 10
Johnny walked into the lab and his jaw drop when he saw his sisters, he knew that his ice cream was addictive and fattening, but he didn't think It'd work so well. Anyway, he quietly snuck past the two fatties that were his sisters and pulled out an old clothes shrinking ray they had, but it didn't make clothes shrink, it made them bigger, the girls planned to smash it for its failure, but johnny hid it in the lab before they could (what better place to hide one of his sisters inventions than right under their noses). He then proceded to sneak out without being noticed. He returned to sissys house to look at his fat cuite, who was in her white panties and training bra.
Johnny: ok I got the clothes enlarger.
Sissy: and I got an extra set of clothes.
Johnny shot sissys extra clothers and they grew to fit her now wide frame. Johnny helped sissy into her new clothes and gave her butt a light smack, making it jiggle, which made sissy blush.
Sissy: h-hey! Not cool test!
Johnny: sorry. anyway, how about we go to the mall?
Sissy: are you nuts?! People will laugh at me!
Johnny: not if I blame it on my sisters.
Susan and Mary have made lots of inventions that end up embaressing people and people knew that if something lame happened to johnny, it was his sisters fault, so he could do anything he wanted, and if it didn't work out, he blamed it on his sisters.
Sissy: well... ok, but if they laugh at me, I sware I'm eatting you.
Johnny: ok, eat me, but good luck finding another boy who likes the new fat you and will feed you.
sissy: you're good.
Sissy grabbed her purse from upstairs and got in a wheel barrel. Johnny, who had been given super strength 2 days ago by one of his sisters inventions, began to pull sissy to the mall.
