Thin String

As the afternoon breeze passes by, you muffle another moan of pleasure. Tethered to the ground only by the string around your ankle, you lay atop your helium-filled cock and balls, aroused beyond belief. Below you, sitting in the shade provided by your ballooned bulk, I lounge nude on a towel, my curves on full display to the world. I don’t care if a passerby might see us, if one would even be out here so far into the countryside. Besides, you have much more pressing concerns than potential spectators. The pressure within your pneumatic penis incessantly teases you, the buoyancy makes you shiver in pleasure, but the pair of scissors off to our left is a clear reminder of the danger you’re in.

“One word, one moan out of you,” I had said, “and up you go.”

And so, with a twist of a valve, the game of the past half-hour had commenced. So far, you had kept it together under pressure, nothing more than rubbery squeaks and creaks had pierced the silence between us. But over time, the pleasure was becoming unbearable. Having one’s fantasy be fulfilled alongside having a dick permanently stretched out and sensitive was like a bomb of ecstasy waiting to go off. You wondered how much longer I was going to keep you out here like this, tied to a block, the infinite sky above waiting to swallow you up at a moments notice.

A sudden yank on the string from below, and you felt a shiver of fear, and anticipation, run down your body. “Feeling alright up there balloon?” I ask, fake innocence dripping from my voice. It’s obvious I know full well how pent up you must feel right now. Yet you maintain your silence, despite how desperately you wish to let loose with a shudder and cry. More jerking on the string, and you find yourself being pulled down, a hand wrapping around your ankle. For a moment, you think it’s over, that I’m going to take you inside where you’ll be safe. But that changes when you feel my hand reach up and stroke along your inflated cock. Burning pleasure jolts across your body and only through a miracle of willpower do you keep quiet as I stroke your penis. My hand finds its way to an inflated testicle, pressing into its side to test the pressure. I can hardly make an indentation, the pressure of the helium pressing back against my touch.

To your horror, you find me reaching up and pulling myself atop your blimp cock, swinging a leg over and straddling it. Despite my weight pressing you down onto the ground, I can’t touch the ground with my toes. Your inflated girth is simply too large, too pumped up to allow that. By this point, stars dance across your vision as your cock engages your brain in a battle for release. It only worsens as I begin to bounce up and down, pleasuring myself against the biggest balloon I’ve ever played with. You can only listen in agony as I moan in delight, the pressure, the pleasure, the need for release all rising.

You aren’t quite aware of what happens next, as your world went black as the largest orgasm imaginable rocked your world upside-down. All you could hear was a roar in your ears, your brain evidently was too busy in the heat of the moment to properly process little things like sight or sound. Just the climax. When everything came back into focus, you saw me covered in perspiration, clearly having hit my own peak, with a grin across my face. The grin told you everything you needed to know. Your moment of lost control had cost you.

“Well Mr. Balloon Cock, time to go up.”

I dismounted from you, grabbing onto your ankle as you rose back up. You felt a cold chill roll across you as I picked up the scissors. Part of you fears being left to drift up and away, but yet you know this was inevitable. You wanted this, you wanted this bad. Otherwise, you would have never said yes so brazenly. There’s a snip from below. You can’t bear to look but you know now that the string is gone. All that stands between you and buoyancy is my hand on your ankle.

For a few agonizing seconds, you wait.

But rather that the feeling of rising upwards through the air, you hear a hiss from below as you’re pulled down again. You wonder what plan I have in mind before you see, and certainly feel, me climbing aboard your dick again. In my navel is a hose, trailing to a helium canister I kept hidden beneath you. My curvaceous figure is swelling even larger, breasts and ass inflating to make me go from hourglass figure to sex balloon. I slide up against you, my chest inflating against your body, my swelling thighs squeezing into your cock. The sound of rubber sliding against rubber joins the hissing. Already, you feel our weight dropping as I become lighter and bigger. You explore my body with your hands, drinking in my filling form as you enjoy the sensation of me pressing my legs into your blimp dick. You can feel my skin lightly vibrating in tune with the helium’s flow, goosebumps covering my arms as I’m enraptured by gaseous delight.

You feel yourself leave the ground as the tank empties, my tits and ass now making me too light to ballast you. We float slowly off the ground, inches at a time. The earth is close, but held out of reach by our buoyancy. You stare into my eyes and see the same thrill in them as you feel inside of you. The thrill of being lighter than air, drifting up helplessly into the sky above. You ask me why, why did I decide to ride up with you? I giggle softly as I press harder against you, my tits squeaking as they’re compressed between our bodies.

“Well, I said you’d go up. I never said anything about doing it alone.”
