Booma gets up, barely, and before your eyes, he Sumo Sizes!
His arms get more muscular, his pecs triple in size and muscle mass, even his very ass gets bigger!
"Alright, lets have another match, but this time whoever wins gets the other to be their slave for a month!"
You can't possibly go with it, but you also can't think straight with your mind full of his gas. So anything to get out of it seems great at the moment.
"YES!! I agree!!" you respond.
Booma gets off you, and after a short countdown, you charge. Needles to say, you have absolutely no affect on the giant in front of you, especially Sumo Sized. He pushes out his belly and knocks you down with what appears to be no effort whatsoever. As you get back up, you get the terrible idea of charging again, thinking he wouldn't see the same attack coming. When you do so, he turns around, pulls his thong up his ass, bends over, and flexes his ass cheeks.
You smack right into his huge ass. As you do, he reaches his hand and grabs your head to keep it still, followed by starting to push it in. The act is followed by a bottom thrust, leaving you flat on your back. Booma then comes over and hits you with yet another Gluteous Maximus,
"GLUTEOUS MAXIMUS!!!" He shouts as he jumps high into the air and onto your whole body. You feelt the pain as Booma grinds his butt on you, slowly, but with great force. When he finishes, your entire body ends up perfectly aligned with his butt crack, including the lower portions of your head (your mouth and nose). Seeing yourself in such a vulnerable position, you scream "I GIVE UP!!" in his ass. Feeling the vibrations, Booma is able to pick up the translation as a surrender.
"Hahaha, awesome! But my first rule as your master is for you to stay there and enjoy it!"
"WHAT!?" you scream into his ass.
Just at the moment, your body begins to feel very warm, and you smell a foul stench reminiscent of a fart. It doesn't take long to realize what Booma just did, and you begin to squirm under his heavy body,
"Hey, I order you to enjoy this!" Booma yells, much to your displeasure, "You will from this day, willingly endure and enjoy my awesome farts, haha!" Booma yells, scratching his huge butt...
