"Hmmm", you thought, gotta make them gassy first. you closed your eyes and sure enough, a banquet of baked beans, sprouts, cabbage, cheesy burritos hot wings, curry and pints of beer appeared.
"Oy mate, check it out", said Ryan
"aww sick bruv" said Curtis, as the three began to gorge themselves on food. Soon, once they had ate and drank it all, they lounged on some chairs that had appeared. All three's belly where stuffed and slightly bulging. So much so they had to undo there belts and zippers, as they lay there, food smeared around there mouths.
"aw mate, i am stuffed said Luke"
"yeah mate" replied Curtis, belching then patting his belly.
Then you brought in the next stage of your plan. Ryan, let out a huge long stinky fart, but as he did his belly swelled underneath his shirt, until he had a firm basketball sized belly
"What the fuck is happening" said Ryan
"I dunno mate, looks hot though" said look, palming himself through is pants.
"guess it does, feels good too bruv" agreed Ryan.
"Yo do it again man" said Curtis, pulling out his cock to wank.
Ryan let out another fart, his belly swelling further.
