Make everyone bigger and start fucking!

You can't help it. The idea had been floating in your head all day and now was a perfect time to do it. You pull up your moob and grab the wishing powder. You take a generous scoop of your sweat your dump it into your mouth and add a pinch of the wishing powder. You swallow and wish in your mind. "I wish everyone was even fatter!"

The thought finished and you felt your entire body be overwhelmed by a different kind of heat than the sauna. You grabbed your mattress moobs as you felt yourself begin to grow. All of the guys began to moan with you as your cocks and balls also grew with your fat bodies. Your fat began to push the guys on your sides away as you became the main attraction of the room. Everyone noticed your guttural moaning and began to pile onto you not realizing all of you were growing. Everyone just grew and grew. Your belly oozed outward consuming more and more space. Your thighs and ass were becoming indistinguishable as the rolls melded together. Your hips were beginning to rival the width of a bus's length. But your cock, oh god, your cock was so enormous. If your ass was that wide your cock was that long. It reached the other end of the sauna and pushed into the fattening Yusuke. Your cock continued to thicken and grow but despite that Yusuke rubbed, licked, and pleasured your enormous cock head. You could feel all of the other guys massive cocks growing and pushing deep into your fat folds.

Finally, the men began to release one by one. Their guttural moans of orgasm delighted you and you could feel the pressure of their cum blasting into your folds of fat. Your own orgasm was building in your cock and it finally came as you shrieked in pleasure. Within seconds your tsunami of cum caked Yusuke and the entire wall in your cum as a torrential downpour of cum came forth from your cock.

"Come on, boys!" You shouted as your monolith cock bucked in continued orgasm. "Let's fuck!"

They didn't need you to say a word. The sumo team humped and fucked fold after fold of your fat. Yusuke continued to keep you in a constant state of euphoria as you came over and over again drenching the entire room in your cum. How long your orgy lasted you have no idea, but eventually you all began stumbling out of the sauna. You watched everyone's fat asses shake and wobble as they all appeared to be at least twice as big as before, Yusuke even more. You, however, had to be at least 5 times bigger. You leviathan ass touched every wall and went from floor to ceiling. Your belly was close too but if it weren't for your red wood cock it wouldn't be touching the ceiling.

"I hope that was satisfying for you, mayor," one of the sumos said. You stood there delighted to feel so massive and enjoying the sweat and grime rolling off your body. But also, the cum pouring from dozens of your folds of fat like they were pockets of cum.

"More than satisfying!" you say happily. "Good luck to you all with your championship!"

The team thanks you and you say goodbye to your love, Yusuke. You stomp through the stadium looking at everyone twice as big as before. If their bellies didn't drag on the floor before, they do now. You step outside to find your assistant larger too and with an even larger vehicle.

"Welcome back, sir!" he says happily. "What would you like to do next? Bigger Burger's new octo-fried menu, Jumbo Jake's and their new 100-gallon lard shake, or whatever else you would like to do!"
