O is for Overinflation

How do I get myself into these situations? Well, okay... if I'm being honest, I know exactly how. Like so many other guys, via my cock.

There she is, waiting for me just like she promised she would. Ada is pretty damn gorgeous, and much more importantly than that, she's a whole lot of fun to hang out with. We've been chatting for weeks now, hanging out and talking about her interests. One in particular kept coming up, so I asked about it more. And more. And now... now I'm here. Driving out into the countryside to meet a beautiful woman, so she can do goodness knows what with me, and to me.

She's dressed in a beautiful black gown, like we're going out ballroom dancing rather than hanging out and doing potentially lewd stuff to one another in the woods. She greets me, surprisingly formal in her manner. She curtseys, and only afterwards extends her hand to shake mine. I think she sees how shocked I am, because as soon as our hands touch, she grins. I watch as she steps back and starts to take off her dress, right there in front of me. She giggles as I realise it was all a game, and I laugh too, watching as she strips down to a beautiful set of lacy black lingerie. She leads me away from my car, into the clearing where her camper van and supplies are all set up. There's a wooden bench, and she guides me to sit on it.

My eyes widen as she straddles me. My cock starts to harden as she begins to sway and dance, breasts in front of my face, crotch grinding down against my own, still dressed only in that skimpy underwear. The look in her eyes tells me she knows exactly what she's doing, so I don't press for answers. She'll tell me what she wants, and what she wants to give me in return. And sure enough, barely half a minute later, she begins to whisper as she grinds and humps against me in that intimate excuse for a lap-dance.

She explains, and my eyes widen. My cock only gets harder though, and my heart races, thundering against the inside of my chest. I know what she's into, and I kinda thought that she was going to have me do it to her. But... to hear that she wants to do it to me? That she wants to inflate me, oh god. Oh god, I can't deny that it makes me nervous. But at the same time, how bad can it be? It's just some air, and she's done it countless times before. I've seen the pictures. The videos. They were... surprisingly erotic. Besides, it'll make her happy if I say yes. I like making people happy, and, I definitely like what Ada does with me when I make her in particular happy.

A few minutes later, I'm naked in the woods. Better to do it naked than to risk tearing my clothes if I get inflated too much, that's what Ada told me. Maybe she's right, maybe she just wanted to see me naked. Either way, she takes a long look at me, eyes lingering on my hard cock as she sets up the compressed air pump. Soon, she's ready. We're both ready, and she slips out of her own underwear before approaching me with the tube and mask in hand. Why does she need to be naked for this? Honestly, I don't think she does. But as she lets me put the mask on myself, a sort of harness to hold the air nozzle in place within my mouth, one of her hands is between her legs, and the other is between mine. Her clawed fingertips stroke my cock and her clit all at once, and we shudder, we moan together in anticipation of all that is going to follow.

She leads me into the centre of the clearing, large enough that I should have more than enough space to grow. She walks back to the pump itself, attached to a generator which is itself attached to the camper van she drove out here in, and turns it on at what I've been assured is the lowest setting. Oh god. Oh god, that's a strange feeling. I'm being filled with air, but it's not going into my lungs. I can still breathe normally, but everything else... my arms, my legs, my torso, even my cock, I can feel them swelling. Stretching. Getting lighter as the air fills them up like a beach ball. Oh, wow. This is actually kind of fun, and I can even see the appeal from a more intimate side. It's like that feeling when you're in a car and go over a bump too fast, or when you're a kid and you push so hard on the swing set that you feel like you've left your stomach behind. That kind of light-headed rush, except rather than being centred in your torso or indeed your head itself, it's tingling through every last little bit of you.

Soon enough, I can't move. I'm a ball, a big fluffy ball with a head, and little stubs of arms and legs wiggling out from my sides. I can feel my cock pressing rather deliciously against my swollen belly, the shaft itself already twice its normal size and girth thanks to the air filling it. Looking over as best I can towards Ada, she's touching herself. Rubbing her pussy while she watches me grow, glancing back and forth between my swelling form and the pump upon which her other hand is still resting. She whimpers. She shudders. Did she just cum? Or, is she on the edge. Oh god. Her eyes widen. Her back arches as she clamps her thighs down around her paw, and... and she hits the compressor pump, kicking it up a gear and sending me swelling far larger and far faster than I already was.

I'm as big as a house now, my face stretching out over my upper body as it grows and grows, my ears and cheeks bulging out, stretched so thin I'll bet you can see through them like a real balloon. My balls and cock feel so swollen now, and as they rub against my body or the ground below, I feel like crying out in pleasure with how sensitive, how good it feels. I can't really see how big I'm getting now because I can't move my head, so all I can do is stare at Ada. Watch as she touches herself more and more greedily, working two desperately eager fingers in and out of her already soaking wet pussy like she can't get enough, staring at me all the while.

Eventually, she can't take it any more. She twists the power up again, and I feel myself swelling way, way faster than before as she abandons the pump. I know I should be worried as she leaves me to grow and grow without any control over how to stop when the time comes, but so eager for what I think she's about to do that I don't even care. Sure enough, she rushes over to me and leaps upon my spherical form. She rolls me until I'm on my back, until my huge inflated cock is beneath her as she straddles and rides me like I'm a bouncy toy, and she wraps her thighs around my huge, air-enlarged erection. It feels so good, so incredibly good as she humps me. I can feel the heat and the wetness of her pussy rubbing up and down my length, her whole furred body grinding up and down the length of my shaft. Over the hissing of the air I couldn't hear her when she was by the pump, but now I can listen out and just catch the frantic whimpers and gasps of her own pleasure.

I don't know exactly how many times she cums while she's humping me. More than five, less than infinity, somewhere in that range I'd be willing to bet. Sometimes I feel the gush of her juices, sometimes I feel the quivering of her thighs growing more intense. Other times it's her shrieking cries that can only be orgasmic as she rocks and rubs her pussy against my huge and still growing form. Up until recently I was so excited by her neediness that I barely paid any attention to my own growth beyond the general awareness that I was constantly getting bigger, now towering over the treetops around us. But, I can hear something else now above the hissing of air and the whimpering of my eagerly humping, hungrily pleasure-seeking friend. Creaking. The sort of creaking that comes with rubber being stretched too far, or in this case, my own skin. I'm still growing as fast as ever, but even with the prep Ada put me through to get me ready for today, I'm getting bigger than my body can handle.

That's when I feel it. My body pressing against something on the ground, and then knocking it over. A second later I know its the pump I've damaged, because all of a sudden the amount of air surging in through my muzzle goes into overdrive. My eyes bulge, not because I'm shocked but because all of a sudden they're inflating beyond the limits of their sockets, swelling and stretching out as I wriggle and gurgle and try to let Ada know that something is wrong. I get bigger and bigger so quickly that soon Ada can barely hump at my cock as it's just too wide, but that fact only seems to make her more determined, more desperate to succeed at her efforts. She screams again. Cums again, and as I feel her face bury itself in my cock to muffle her cries, I wonder if she can see through me. I wonder if she'll realise just how thinly my body is being stretched, and wonder if she actually intended to push me this far.

"O-oh my god, Jeeves!"

Finally I hear it, her gasp of shock as she pulls herself free from her pleasurable reverie long enough to see the truth of the situation she's gotten me into. I feel her sliding down my body and trying to wriggle underneath me, to get to the pump and shut it off. Even as she tries though, I know it's too late. I'm too big, and she can't get to it without risking popping me. She can't crawl underneath me, she can't push me aside. All she can do is drag herself back up onto my quivering form as I feel myself stretched thinner than strands of cotton candy, and up to my face.

This is it. She's going to look me in my bulging eyes and tell me she's sorry. That there's nothing she can do.

I hope she knows I don't blame her. I hope she knows that even though I didn't want it to turn out like this, I had so much fun making her feel good.

I...

Oh.

Oh!

I feel her hands on my muzzle, the one part of me that hasn't been inflated as it's bound by the mask and the tube pressed into my mouth. I feel her tugging at the clasp, held so tightly by the flesh and fur being inflated beneath and all around it. She's trying to pull the hose free. To stop me growing manually, even if it means she won't be able to reverse the pump and shrink me back down as she originally intended.

I'm creaking and groaning so much, I know that one misplaced finger, one movement too quickly upon me from her even as she fights to save me, and I'll pop. I know it's a long shot, but I put my trust in her. I put my faith in her to do this, to save me.

About five seconds later I feel the tube wiggle between my lips, and a moment after that I feel it slide loose, and free.

Letting out a gasp, the air from that exclamation continues to rush out of me. Slowly, not nearly as fast as if it was being pumped out, but enough to reduce the pressure. To let my body know that it's not being stretched any further than it already has been.

I look around as best I can, sky above, horizon way off in the distance, trees far below me. It's going to take me quite a while to deflate from this size, and until then I can't move. I can't really do anything.

Thankfully, I think Ada has a plan for how to help me pass the time, not to mention how to keep me hydrated while I'm stuck like this.

I feel her straddle my now unbound muzzle, and begin to grind her wet pussy against my face. Her clit rubs against my nose, and I can smell her deliciously intoxicating aroma of desire. Her juices drool between my lips, wetting them, soothing my throat with their tangy moisture. She leans forward, cuddling against my hugely stretched and swollen features, and starts to hump me all over again with a giddy, lustful moan.

I'm glad I'm not inflating any more, glad I'm not still growing. But... if it takes me a while to deflate again, even if it is happening because I was dangerously _over_inflated to begin with? I think I'm actually okay with that.

"Oh... ohh Jeeves, I... I'm gonna cum! Oh god. Oh! Oh!! Yes!"

Yeah.

So long as Ada is here and still having fun, I'm definitely okay with taking my time.
