Gainer house part 3: the air inflation room
Added 2025-10-26 15:30:49 +0000 UTC
You barely arrived at the Gainer house and you were already larger than you could ever imagined. Bob & Oscar fed you 3 breakfast, each one being several dozen times bigger than your normal meals. Youâve grow so big that youâve filled the entire bed with your round body. Youâre so stuffed that you canât even move. Is that the end of your stay? How could you enjoy everything else that the Gainer House has to offer if you canât even get up?
Thatâs when the two big bears answered your question by grabbing the bedhead and pulling simultaneously: the bed had wheel and they were starting to move you around. "What a relief!", you thought, happy that you wouldnât spend the entire visit locked in your room. They wheeled the bed through the double doors, and your journey began.
Oscar looked at you with excitement, knowing that we was about to proudly show his creation.
O: "Itâs a good thing that your room is the closest to the entrance, so youâll get to see almost everything while I roll you to the pool!"
"Oh the pool! Sounds nice to take a sun bath to relax after this immense feeding", you thought.
O: "To your right, you can see the supply room. Itâs not an ordinary room⌠You might not believe me, but thereâs an infinite amount of anything you can imagine in there. But hey, you donât have to believe me. Although, after your week here, you might start to believe me when I say that everything is possible here! (He winked.) If itâs food you want, you just open the door to one of of the many cupboard or fridges, and the thing you were looking for will be there, magically. You can also wished for any accessory, object, sex toy, or even brand new inventions. A-N-Y-T-H-I-N-G. Think about that."
He was correct; you couldn't bring yourself to believe him. Yet, the vision of a crate overflowing with every type of chocolate bar you know flashed in your mind. How could you still think about food while being so big that you canât even walk?
O: "And now we are entering the "Corridor of kinks".
As if your day wasnât kinky enough already.
O: "We all like to stuff ourselves here, but some people are looking for something more specific⌠you know? The first room is Richardâs favorite room. In fact, he took control of it as soon as he saw it. The guy was almost in tears when he saw everything he could do in it! He he he. Itâs the air inflation room! I think heâs in there right now. Wanna see?"
You offered a timid nod, but you were extremely eager to see what was going on. To your surprise, those kinky rooms had floor-to-ceiling windows, letting outsiders watch the inflatee in actionâa free live-gaining event! But for the more reserved guests, there were also heavy curtains, offering privacy for their most intimate moments. They roll you near the window, you could finally take a peek inside.
A man was reclined on an oversized chair, arms and legs extended in a starfish position, his body tilted back. His limbs hovered in the air, pushed outward by a massive spherical belly. You were so captivated by his enormous midsection that it took a few seconds to notice the tubes extending from his mouth and rear, connected to what resembled a fitness step. When the big Richard eagerly jumped onto it, you realizedâit was actually an oversized foot pump, sturdy enough to accommodate a 350-pound man. Needless to say that the amount of air it produced was enough to instantly blow the inflated man a notch further. His arms and legs bounced slightly with each expansion wave.
O: "The pumps are Richard mastery. Nothing delights him more than a belly inflated taut like a tire. He wonât stop until youâre on the verge of blowing up. And the balloon-man is Sergey, a regular of the inflation room. He seem to get bigger every time I see him inflated."
Richard was caressing the immense belly of his inflatee while talking to him. You couldnât hear the conversation, but you could see that despite looking about to blow up, the ballon man was nodding. More and more violently. He had slipped into his deepest fantasy, and wonât stop despite his entire body creaking and gurgling out of protestation. The pain was muted by his desire to grow. Bigger.
Thatâs when Richard started to jump again and again on the pump, blowing up the man at an alarming rate. Every part of his body was swelling up, rounded out, resembling more and more like a balloon.

"Oh my god! He should stop right now!! Heâs about to BLOW!"
While the poor guy expanded like a blimp on the verge of exploding, Richard stopped for a second and walked in front of the window, winked at you, and closed the curtain shut. This extreme air inflation will linger endlessly in your mind, resurfacing in your thoughts while you jerk off for years to come.
O: "Donât worry, he canât be harmed while in here. Magnus developed a powerful protection spell that assure us that there would be no tragedy in our house. If someone crosses the limit, he would wake up at his own house, back at the weight he was when he came here, wondering forever if it was all only a dream. Itâs some kind of "Game over", a disqualification preventing you from doing more gaining sessions here."
"But then", you replied, "Why would anyone ever stop?"
O: "Because you might not die when you pop, but even if your body reset after the fact, youâll still remember how it felt when your body exploded. Is this something you would want to experience?"
"Oh god! No!!"
O: "Haha! Well, thatâs the most exciting thing around here: reaching the absolute limit that your body can endure without exceeding it. Playing with fire, battling to stay in control⌠You know what I mean? And trust me, your limit while in Bear Valley is way further than might think. Just look at your breakfast belly!"
SLAP!!!
He slapped your belly, sending a shockwave rippling through your body like an ultrasound, making you acutely aware of just how much space you took up on the bed. He made his point.
Even tho the air inflation room what kind of worrying, you were hard from imagine your entire body blimping out like that man. "Holy shit, that must be something.", you thought.
O: "This afternoon, youâll get to make a choice. Youâll select which one of our stuffing room you want to use. Inside it, one of our friends is gonna offer you a challenge. If you complete it without blowing up, youâll be the king of the day, and all of the visitor will treat you like one. You can also quit at anytime. If you decide to stop, and youâll get a second chance tomorrow, and every subsequent day. Letâs show you the other rooms."
The bed started to roll again as Oscar and Bob pushed you further down the kinky corridor.
