It's his son!?

"Morning, Beastie," You holler as you approach Harry. He blushes very quickly and lowers his head out of embarrassment and you laugh at how silly he looks thinking he can hide when he's nearly 5000 pounds of sweaty, musky fat.

"Maybe not while we're on campus," He says quietly. "But good morning handsome." He stomps into the lecture hall with you following shortly behind. Your giant sweaty bodies fill in the aisles going down and cover the seats and other students who were daring enough to sit in the aisle seats in your musky sweat.

You take your seat at the bottom of the lecture hall right in front of Harry and take up dozens of seats with your enormous ass. You sit there calmly and enjoy the lecture and learn. You begin to have a strong boner realizing you really enjoy watching your professor work with his amazingly hot body. The sweat stains grow more and more as he can't help but be his old thin self and walk around pacing back and forth and using his hands a lot. His flabby arms wobble and shake wildly as he gets very evocative with his teaching.

Eventually, the bell rings and the rest of the class quickly shuffles out leaving you and Harry alone at the bottom of the hall.

"How are you feeling?" You ask him as he packs up his things.

"Good, good," he says with a bit of a sigh. "I- I knew we shouldn't be, you know."

"Fucking?"

"Together," he blushes at your bluntness and quickly tries to correct you. "So I kept it as secret as I could from the other faculty. But I couldn't lie about it anymore. I spoke with the dean about our relationship."

"Oh," you say a bit surprised. "What did he say?"

"I was told to end our relationship," Harry says. You feel the wind get knocked out of you as your heart sinks deep into your fat chest. You even feel yourself sink into your fat as if the reality of your tonnage finally kicked in.

"Oh, okay," You struggle to find the words to say before Harry begins stomping over to you and pushes against you taking your hand.

"No, no, Don't worry. I told him I couldn't do that." Harry explains quickly to comfort you. "I made arrangements with the dean instead. You may continue to attend my class, but I will have your assignments and essays graded by another professor. And we can make this official."

"You mean?"

"I would like to ask you to be my boyfriend," Harry beams with a smile at you. His handsome face was framed by his gorgeous white beard as his fat cheeks dimpled in delight. You tighten your grip on his hand.

"I would love that," you say relieved.

"Sorry, I should have explained that better," Harry says as he just looks at you happily. "Uh, please. Let me treat you to lunch. We could go to that buffet again."

"No," You tell him a bit mischievously. "Let's go to the food court."

"Oh, okay," he blushes and nervously agrees. He grabs his bag and the two of you stomp up the stairs and out of the lecture hall. You hold hands as you waddle across campus and enter the food court. It was a spacious place easily able to sit hundreds of students as it was connected to the main building where all of the student services were. It was like a student hub where everything you needed was.

Everyone stared at the two behemoths holding hands as they stomped to an open 8-top table in the middle of the room. Harry looked at you and you nodded with a smug grin, so he took his seat. The two of you dominated the table and pushed away the chairs as you just sat on your fat asses for chairs. Eventually, and specifically for you two, a student manager who was working the food court came up to both of you.

"Afternoon, are we eating here today?" He says apprehensively. You grin knowing you were about to swamp each and every kitchen in the food court.

"Five of everything on every menu please," you say. The manager looks concerned before Harry corrects you.

"Make it eight. Me and my boyfriend are quite hungry." The manager nods before running between each and every kitchen to give them your order. You and Harry just smile at each other as you wait for your food. It begins to come out one at a time trickling in as you and Harry grab everything in your hands shoveling it all into your gullets. Burgers, fries, pizza, pretzels, tacos, you have a good variety to eat as the food court watches in horror and wonder. You and Harry have no shame in hiding it anymore as you share food with each other and groan in orgasm as your bodies react to how good the food is and how much of it you are eating.

It doesn't take long before the food is done and Harry puts it all on his card. You both happily and proudly leave the food court to go to the park nearby. You sit on the grass and unashamedly lick the food debris off each other and make out.

"I could get used to that," Harry says happily after your finish another long and passionate kiss. You finally separate and allow your obese bodies to settle.

"Me too," You say. "I think I'll like having a sugar daddy who can pay for my appetite."

"I think I'll enjoy having a young boy toy around to help this old man get even fatter."

"How much weight have you put on since you got infected?" you ask.

"When I first got weighed I was 4878 pounds," He says. "Since then I reached 4937 and it's only been about a month since I got infected. So about 60 pounds in a month. Probably more as well since I last weighed myself a week ago, and I've had some encouragement." He smiles happily at you. "How much do you weigh?"

"I actually don't know, we haven't gotten an official weight 'cause I haven't found a scale big enough for me. The doctor said I was probably over 8000 at least."

"Well, I know where we can get weighed. Perhaps we make a date of it?"

"I'd love that-"

Your calm moment in the sun is interrupted by the guttural moaning of someone nearby. You and Harry look to find another student who has the genital infection. The guy was a much more average build than your brother, and his genitals were a bit smaller. Only a bit though. His testicles reached his shoulders and spread out wider than he was tall. His cock was thicker than himself and was probably eight feet long. The guy was already cumming hard as a jetstream of cum blasted from his cock and splattered all over the park.

You saw firsthand again just how powerful the orgasms were. The guy tried desperately to stand through his orgasm but his entire body was in orgasm convulsing and throbbing. His knees gave out and he fell over his cock and quickly submitted to it grinding it against the grass in an effort to orgasm more.

"Ah, Danny," Harry says. "He got infected a few months ago. It happened right in my class." So that's who's infected that he knows. Well, now it's just a matter of time which one of you gets infected.

"And he's already that big?" You say. "My brother's only a little bigger than him and he's had it for five years."

"Your brother has that infection?"

"Yeah, he got it right after high school. As I said, he's just a bit bigger than that guy. Although my brother is much fatter than him, and buffer."

"Well, it is quite the workout. In time Danny will have quite the muscles from his orgasming alone," Harry explains as Danny continues to howl in orgasm over the two of you. The white cum covering the park grows more and more as he still is pumping his cock for more.

"Could you imagine if one of us got that?" You tease him to see what he thinks.

"It is a wonder I never did," he says.

"Why?"

"Well, my son has it." You are taken aback and stunned.

"Wait, you have a son?!" You nearly shout.

"Oh, I'm so sorry!" Harry says as he realizes that he never told you. "I should have told you that before we moved forward! Yes, I do. His name is Brian. He's 47. He was from my marriage when I was younger, before I realized, well." and he looks to you. You realize how awkward it is having this conversation as Danny is still howling in orgasm just 20 feet away and the splashing of his cum in the park is only growing louder.

"Oh, before you came out as gay?" He nods.

"I hope that doesn't change anything, but I understand-"

"No, no. I just didn't know!" You say. Wait? You realize he said his son has the infection. "But, you said Brian is infected?" He nods.

"Yes, he has had it for over 20 years now." 20 years!? "That's why I'm shocked I never got it. Long-term exposure to these infections usually, and exponentially, increase the chances of catching it as the virus wears down the immune system. But I never seemed to catch it from him."

"How big is he?"

"Now? His penis is about 73 feet long. His testicles are about the size of that building," and he nods to the Arts building that's three stories tall and at least a hundred feet wide, or more.

"Wow!" you say surprised. "I'm, sorry to hear that about him." Harry starts shaking his head.

"Oh no, don't be sorry for him," Harry says. "He's like us, he loves it. If he had some way to make himself bigger he would take it. He wouldn't trade that infection for anything in the world."

"Well that's good, my brother's the same way. He's almost immobile from his dick and he's excited about it."

"That's good. You know, we are more alike than I thought." A beeping started coming from your professor and he pulled his phone out from his sweaty shirt pocket. "Ah, I need to get going. My next class is in 15 minutes."

You both haul yourselves up and just admire the still-growing pond of cum that Danny is expelling from his cock. Harry tells you that the first few months of the genital infection are much worse than the fat injection as yours is only the ravenous hunger on day one. The genital infection is months of adapting to the hypersensitivity of the enlarged genitals.

You say your goodbye and stomp to your next classes separately. You grow excited in anticipation of this coming infection. Which one of you is going to catch it? How big are you or your professor going to grow? When is it going to happen!? The questions brew in your mind as you wait for the fateful moment.
