Male inf story of my own creation.
>You stared at that tank, and the other end of the hose you had connected to it.
>"Is this really a good idea?" You asked to yourself. You lived alone so its not like anyone would walk in on you.
>After one final moment of deliberation you took the hose and pushed it into a pair of cheap underwear until you felt it go between your cheeks and into your asshole.
>You couldnt help but let out a moan as a tent began to rise in your underwear, and it felt so good you just HAD to push it a little deeper.
>With a groooan you pushed it far enough to feel it was secure, and with one hand fondling the fabric that held your dick, which was rock hard and throbbing against the fabric, your other hand shot out, grabbing the valve and jerking it wide open.
>You were barely able to hold back when the hose started jiggling, but once the cool gas started blasting in, there was a wet spot on yout underwear.
>You couldnt see them though. Your eyes were drawn to your gut as it ballooned outwards fast! Already you looked heavily pregnant and it wasn't looking like it would slow down.
>Your hands were shaking, unintentionally opening the tank as far as it would go, accelating the growth further!
>Your mind was starting to cloud with bliss, so it was hard to notice your gut suprassing any size a woman's pregnancy could reach, looking more like a rapidly expanding beachball.
>3 feet, 4 feet, 5 feet. The gas seemed almost eager to fill you up, but you could feel something more, a tightness in your hips, finally moving your hand off your dick for a moment you could feel them inflating too!
>You tried to fool around with your underwear, to pull them off, but your hips had already grown so wide the eleastic couldnt stretch over them. So you went back to trying to fondle yourself, but now you had to work to reach them as your hips grew and started to squeeze your dick out of your reach.
>You had to swap to groping your own sensitive gut, and that immediately rewarded you with pins of pleasure across your stretched gut. It was so wide you couldn't even touch both hands in front of it.
>A soft sh-rii-riiiiiip filled the air only for a moment, and a billowing FWOOSHMP could be heard, but you could feel a tightness on your hips. Were you full? You didnt wanna be yet you still had a lot of tank to take! Or you hoped you did.
>If any onlookers could see you, they'd see a massive gut first, easily 10 feet across, with uncovered hips that were slowly starting to peek out aroubd them, underwear in shreds but barely holding on by the elastic.
>You could feel the elastic waistband down there, and even used a hand to test its stretch, it had very little to give, pressing that hand into your hip and the other one into your gut, they still squished, you could take faaar more.
>Before long a TWANG, followed by a soft smack could be heard as the remains of your underwear were launched off.
>Carefully you tried to walk towards the glass doors to loom at your reflection, and had no luck, you had to end up waddling over to them to see your ridiculously huge pear shape.
>Neither your gut nor hips would fit out that door anyway. And with your gut taking most of the gas your hips were only partially visible, but turning to the side you got to see.
>Your butt had grown to the point where each cheek would take up an entire couch cushion, and you groped at what you could reach to admire your own body.
>As you watched your reflection copy you, you saw it, and by extention yourself, start to rise off the floor. You kicked your feet ss they rose for what little that would do to help, but you couldn't control the rise from the helium within you.
>Slowly your body rotated as it rose, until it gently and silently bumped against the ceiling, but that touch released a flurry of horny noises from you.
>As you looked from your angle you couldnt see or even do much, you were squarely stuck, the gas continuing to pour in and making youe gut grooan in peotest as it further stretched.
>You wish you could do more to sate the burning lust within you but you couldnt reach anything, not your dick, not the hose, not the tank, nothing!
>But you did have one 'lucky' break, the contant gas flowing into you had finally stopped, the tank must have run empty, leaving you a massive pear shaped balloom of a guy on the ceiling, entirely unable to move and struggling to do more than hump at the air and moan. At least for as long as this lasted~
