More than Bargained For

I had moved into my new home about 6 months ago, I found the ad on Facebook asking for a roommate. I had been trying to move out of my parent's place for the last year, and had finally had my chance.
I had met with the guy who would soon become me roommate; he was in his early 30s, just a few years older than myself, he had nearly trimmed hair and a full trimmed beard, he was well built, his biceps were nearly the size of my head, and he looked as though he had been a linebacker in college football. I couldn't help but find him extremely attractive.
He introduced himself as Tyson, and gave me a quick tour; his room was the biggest, mine was across from his and was about 2/3rd of the size, both with our own private bathrooms. Along with the living room, and a third room that acted as the home gym. The kitchen surprised me though, as it contained more food than I had seen in four homes combined. After seeing my astonishment Tyson stated that he was working on bulking up for a body building competition at the end of the year, and if I moved in I would be expected to keep him bulking. I didn't hesitate to say yes.
Now, nearly 6 months later, I had Tyson sprawled on the couch in front of me, his handsome bearded face had plumped up a little, his cheeks having gotten thicker and his neck showing signs of a double chin beginning to curve out. His arms, legs and chest were still mighty and powerful, even his ass had become more swollen in the last few months. But my favorite part was the gut he now had bulging out from his middle and swelling into his lap. His shirts had all been tight around his arms and chest and they had grown slightly tighter, but his middle had suffered the most damage (well, the most bulking 😈) and no longer could fit within his shirt, nor really any of his shirts anymore. Instead, his shirts had grown so snug over his middle and had began to rise up, exposing more and more of his hairy middle, until now they all stopped a several inches above his deep cavernous navel.
Several empty burger wrappers and fries boxes were strewn around abs next to him. He was so bloated at this moment that his jeans had even lost their top button and the zipper gave way to his expanding girth, that now his jeans sat wide open and hugged against his gut, a small tent in his black underwear peeked out and was barely visible from the opening of his jeans and under his gut.
He groaned from his stupor, with a hand on his swollen gut, as he saw me enter the room with another bag of three quarter pound double bacon cheese burgers.
"No, please," he mumbled, weakly trying to wave me off, "I - uuuUUURRRRRRP! Oh, I can't eat anymor-UUUURRRRRRP!"
I just smirked at his belching and groans. "But we gotta bulk you up even more, you only have 6 months remaining before the competition. You have a lot more growing to do before you even stand a chance of winning."
"No, please, UUUURRRRPP! Ohhh!" I watched as he clutched his gut and tried to pull himself up off the couch, but he was weighed back down by his bulbous hairy belly. "Please, I'm already so huge, this is much mo-UUUUUURRRR than I bargained for. I don't want anymore. You need to get out."
"Like hell," I said as I set the food on the floor next to him. I then put a hand on the lower side of his gut and pushed it back, causing him to groan and belch again as I reached under with my free hand and pulled down his underwear to reveal his swollen dripping cock that was just beginning to sink into the start of a plump fat pad. I took hold of his cock and make him gasp. "This tells me you love all of this. All those previous nights tell me the same thing, the countless times I've seen you jerking off as you played with your fat self. I know you like it, in fact you love it. You're just scared that I've been able to pack so much fat onto you in such a short time, and it scares you that you're losing yourself to it."
"No I don't! I-"
"Yes you do," I exclaimed as I let his gut flop back down onto his cock and grabbed at his fat underbelly. "You love this. I know you do. And I'm going to give you more. Got it?"
There was a long pause as he stared at me, then he glanced down at his gut and cradled his belly with both hands with a worried look on his face, before he looked back into my eyes.
"Yes."
"Yes what?" I raised a brow as I undid my pants, revealing my own hard cock and slapped it against his tight swollen belly. His eyes grew hungry and I knew he was now mine. He reached down and grabbed a burger from the back before he answered.
"Yes, sir." He unwrapped the burger and began eating. It was slow, but he was eating.
"Good," I smirked as I aimed my cock into his belly button and plunged into its depths. He whimpered in response as he came all over his jeans and belly, belching as he did.
The next hour was spent by him whimpering, moaning, belching, and crying out in pleasure while I fucked his belly good and hard. After I came in his navel twice, I had to feed him the last couple burgers, but I didn't care, I was going to make sure my hog ate every last piece. I even got creative on the last one and managed to maneuver him to kneel over the back of the couch while I buried my dick in his ass and forced him to eat the last burger. He came four more times while I drilled him, how cries of pleasured pain threw me over the edge, twice.
He didn't know that I had withdrawn him from the body building contest and signed him up for a different one. I had 6 months, and my hog was going to grow huge and be biggest in show.
