September 2025 ~200lbs June 2026 ~305lbs

In just around 9 months I somehow gained 100lbs, I’m not saying like idk how but I didn’t expect it to come this fast and it’s so very exciting. I can’t wait for the next year to see how much fat it will bring me

I can’t believe what I’m doing to myself. 😵‍💫 I’m gonna be chugging heavy cream every day this month (and I doubt I’ll stop after that). I’m not gonna lie I cheated and started a couple days ago and I already feel so fat. Anyways, if anyone wants to watch me blow up this month you know where to find me 😉

I’ve been in a relationship for a couple months now, and my boyfriend has gone up two pants sizes in those two months… He is on the smaller side - his pant size was 28 x 30, but now it’s 32 x 30 and he’s complaining that they’re starting to feel tight. His face has rounded ever so slightly, he has the smallest love handles forming, and the squishiest pooch of a tummy, just slightly hanging over the waistband of his jeans.

He doesn’t know when to say no to food. He just eats and eats, and eats, and eats, and eats some more.

We went to dinner with friends the other day and he cleaned his plate… before finishing off mine and our two friends plates as well. (Imagine the portion sizes if my fat ass couldn’t finish my meal!)

It’s so incredibly hot to see, especially since I didn’t lift a finger… He’s doing it all to himself.

I’m a lucky girl.

Here we are, 4 months later, and he’s gone up another size - 34 x 30… Still eating, eating, overeating, all on his own. He can’t say no to food…

He’s not working out as much, and the most recent time he went, he said he had a hard time getting through the workout he was so out of shape.

His shirts are so tight I see his love handles bellybutton through them.

Ugh, it’s so freaking hot. 🥵🥵🥵

5 months later, and he went up yet another size - 36 x 30… and hit a Wendy’s after getting new jeans to get a Baconator meal. Large.

He’s started wearing larger, looser shirts, but I’ve noticed even his sweatpants are getting a bit snug, not fitting over his belly which has begun to hang the tiniest bit… I saw it hanging out of his shirt *and* coat a few weeks ago, which was essentially the hottest thing ever.

He hasn’t done any kind of workout since the last time I posted about him, and he’s eating the same, if not more… It’s like he’s completely lost control all on his own… and I can’t wait for more.

(Plus he’s added a few inches to my waistline, a few pounds to my scale because he insists on feeding me if he eats… Ughhhhh, I’m so lucky! ❤️‍🔥)

Another 5 months later and I noticed he had a pair of 38 x 30 pants. He didn’t tell me about going up another size. He’s gone up 10 sizes since we met. He’s so soft now.

He’s solidly wearing XL shirts. When he lays down wearing his XL shirts, you see a little belly hanging out.

The shorts that were big on him last summer technically still fit, but the little 1.5 inch slits in the hem no longer shut… They’re spread wide open across his fuller thighs. He can’t get the waistband over his belly. His belly and love handles hang over the waistband. The shorts that fit perfectly last summer no longer fit at all. He can’t button them.

When he wears golf shirts to work and tucks them in, you see how big his belly is. It’s really hot to think about new people being hired that don’t remember him doing push-ups when the store was slow. That all they know is this tubby guy. His super-fit boss is concerned about him because he remembers and has just seen him balloon for the past year.

I think he’s stopped trying to work out. The equipment he bought gathers dust in the corner, going unused. He doesn’t even try going to the gym anymore. (He might have canceled the membership.)

He no longer makes his lunch for work - he orders out.

The other day he literally had fast food for every meal - Wendy’s for breakfast (but not Wendy’s breakfast), Taco Bell for lunch, and McDonald’s for dinner. I’m unsure how often that happens these days… But I’m willing to bet it’s more than I’m aware of.

Having sex has gotten harder for him - he gets out of breath faster, his stamina is starting to slip, and our bellies are starting to get in the way a bit… (please note that I’ve maybe gained, lost, and regained anywhere between 1-10 lbs at any given point during the entirety of our relationship, so I don’t think my tummy is the issue here even if I’m still the bigger one…[for now at least…])

I swear I had nothing to do with it - he’s done this to himself. All I do is let him know I love him the way he is.

He’s so hot 🥵 ❤️‍🔥 .

I’m so freaking lucky! 💗

It’s 9 months later and I think he’s still wearing his 38 x 30 pants, but now his belly definitely hangs over his waistband. A lot. Everything is bigger - his thighs, his chest, his arms, his cheeks, his back, his butt, his belly. If he were to shave his beard, I’m sure I’d see a double chin. I even see the back of his head is chubbier.

The coat that he wore earlier this year - the one his belly hung out of momentarily- no longer closes. The zipper would need a good four inches around his chest alone to have any hopes of zipping… I’m guessing his belly would need at least 5. His belly sticks out a couple inches from the rest of him.

His XL shirts cling to his stomach - you see his belly button through them, you see his nipples through them, you see his love handles and belly bulging over his waistband through them. If he were to lift his arms high enough, you’d see some soft, delicious belly. They ride up even more than they used to when he lays down.

He’s been drinking liquor more… not enough to become a problem, but enough to take a real toll on his waistline… He doesn’t have a night cap everyday, but I’d be willing to bet he has more than one a few nights a week.

I think his mind wanders to food first these days… We were in the car talking about stupid things teenagers do, and I asked him if he had ever done a donut (meaning the kind a teenager would do in their car), and he replied with “I’ve had a donut… I’d eat a donut for you.” That was so hot, because it was completely unprompted - I maybe fed him a few donut holes one time, more than two years ago. It took everything I had not to ask if he’d eat a dozen in one sitting for me. Later we napped together and I turned myself on thinking about feeding him a dozen donuts and how big he could possibly get for me if I was actually pushing any of this… while giving him belly rubs and feeling up every inch of soft, squishy goodness around his middle.

His belly has gotten even more in the way while having sex… I feel it pressed against mine even when he isn’t breathing heavy, thrusting into me, trying to get off. It’s just there, making things harder for him. It’s so hot to see him struggle.

I let him know I think he’s still hot. He asks for belly rubs every time I see him.

Goodness… He’s such a fatass now… 🐽🥵🐖

How did I get so lucky? 💗💗💗

It’s been about 4 months since my last post and I think he’s finally starting to realize that he’s out of shape…

For the holidays, I got him some new XL sweatpants and some dress shirts. His belly was 51 inches around when I measured him for the pants back in December - only two inches less than me. His old large sweatpants were getting very tight, and the new ones I got him are starting to get a bit snug. His belly is starting to gently strain the buttons on the new dress shirts… Not enough to get a peek between buttonholes, but enough to tell his belly has gotten bigger. His XL t-shirts have been riding up and exposing the tiniest sliver of underbelly… I think he finally got himself some 42 x 30 jeans, but he hasn’t been wearing them… I wonder if he outgrew them too.

It shouldn’t come as a surprise as he was eating fast food or take out for breakfast, lunch, and dinner almost every day for three months straight. The daily Big Macs, double fries, and soda will do that to you… As well as the breakfast sandwiches, and burritos.

He parks his car on the street outside of his office instead of in the parking lot a block away where he used to go because “The walk was getting long.”

Over the past couple months, he’s been breathing heavier doing simple, everyday things. Sometimes he’s just sitting down, breathing so heavy it sounds like he’s snoring, and I have to look over to make sure he hasn’t fallen asleep. He’s had to catch his breath for a few moments after climbing a single flight of stairs (stairs I handle everyday, breathing normally.) But what made him catch on to his declining fitness was the last time we had sex… While he was thrusting, he actually worked up a sweat and huffed and puffed for 15 minutes after finishing, trying to catch his breath. That’s what made him notice…

But it wasn’t enough to stop him from getting a snack once he caught his breath and asking me for belly rubs. 💖🐖🐽

I think he’s going to slow down a bit… but we’ll have to wait and see.

For now he’s still growing (not on purpose), and this has been the hottest thing to watch him do to himself.

He’s so hot. 🥵❤️‍🔥🥵

How did I get so lucky? 🥰🥰🥰

It’s been about 5 months since my last update, and tbh, I’m not sure if he’s gained anything or lost anything. He is mostly wearing 2X t-shirts now that ride-up some, but don’t expose anything. He got new shorts since the ones he’s had the past two summers no longer fit over his butt.

However, when we had sex the other day, he literally tuckered himself out and didn’t finish. He was sweaty, breathing heavy, and clearly exhausted himself before giving up completely, stopping, and taking a nap. (Let’s just say that wasn’t an issue for me because that display was more than enough to get me going.)

After the nap, he tried again, and with some effort, he managed to finish. Sweaty, struggling to catch his breath, but he did it.

(Is it messed up that while I’ve never actively done anything to get him this big and out of shape, I kind of want to make it even harder for him to have sex with me, not by making him bigger, but by making *my* belly even bigger, resulting in it being harder for him to get inside me?)

I love my round, soft baby.💖🫃🏻💖

He gets me going in ways he didn’t even know were possible. 🥵❤️‍🔥🥵

How did I get so lucky?🥰🥰🥰

It’s been about 3 months since my last update, and I definitely think he has gained. He’s still wearing 2XLs that ride up, but my confirmation is that we went to a Christmas party last night and he wore his most recently purchased suit jacket (from earlier this year, around the end of January)… It fit around his shoulders okay, but there was no way that it could reach to button across the expanse of his belly. There was a good 4 inch gap between the buttons and the button holes. They wouldn’t meet. The dress shirts he got around the same time still button (they weren’t as snug in the fitting room), but a few are strained, with the tiniest slivers of belly peeking through.

He definitely ate at party’s buffet, but I know I ate more 😅… They had a photo booth that we took some pictures at and I looked enormous… (and I’m not that much bigger than him measurement-wise.)

Holiday season is here! 🎄🍩🎅🏼 🍪 🎉 🍫 I’m hoping that he indulges so much that we need to go on another work clothes shopping trip because his button-ups won’t button around his belly… or that he pops one. (Preferably around me.)

Happy Holidays to you all, I’m wishing you all tasty food, lots of love, that you all reach your goals, and that you get as lucky as me in the love department! ❤️💚❤️💚❤️💚❤️

Almost 3 months since my last update, and my fiancé might have gotten a little bigger… or I just noticed that his belly is too big for his frame?

After revolving sushi (between the two of us, we demolished 30 plates, including tempura and multiple desserts; I was painfully full walking to the car), we went back to his… and there were sexy times.

While he was on top, flat against me, I felt how his belly sort of folded over his sides a bit and could feel the hardness of his muscle maybe three inches from where his belly folded? I’m not sure this makes much sense, but the softness was APPARENT to me. I don’t think it’s really been apparent to me like that before?

Also, I should mention, my mom has mentioned he needs a new coat because she saw him struggle to fit and zip it over his belly… and the seams by the pockets seem to be giving some… one pocket has started to tear. (And I think suede is a difficult fabric to tear at the seams, unless it’s well worn.) I saw his belly effortlessly peeking out the bottom of a work shirt that he used to be able to tuck in (but no longer can) and the fleece they gave him the other day too, and was a little feral over it… 😳😅

I keep asking myself, how did I get so lucky? 🥰🥰🥰

I’m so thankful he’s my fiancé! ❤️❤️❤️❤️❤️

will I make the cut?

Hey dude, those gains are insaneeee. Can I ask how you started gaining? I’m about the weight you were before you blew up

Thank you and yea the answer may upset you but I cheated by using Boost VHC, got myself like 6 cases of it and chugged over 5 a day for a couple months, went from 156lbs to 191lbs in 3 months.

Ofc I was eating big too but liquid calories were my cheat code for blowing up. They don’t taste great so I’d recommend just making a gainer shake at home- much cheaper and easier on the stomach.
