All purple

Every single balloons in the room, including the one you're resting upon, are now a deep opaque purple, the light shining off the stretchy latex. They float around you, sometimes bumping and sliding off your skin, their stretched latex gliding effortlessly and sending goosebumps crawling up your arms and legs.

The huge balloon you're impaled onto slowly drifts towards the bed, gently landing on the mattress before it begins shrinking, slowly dropping you on the bed. The toy lays flat and deflated on the furniture and you rise up on your knees, still looking at the spectacle and wondering what Ava has in store for you. The remaining party balloons doesn't seem to follow any pattern in particular.

Eventually, Ava makes her move, every balloon converging on your position. You can't fight them as they begin pressing their somewhat tight bodies against yours, squeezing you sensuously all over and under. You can feel some of the toys accessing your hard sensitive penis, the joy rod pinned between two balloons. One from above, the other from below. Before you know it, you're tightly trapped in a cocoon of purple balloons, the toys slowly lifting you off the bed once again.

Try as you might to shove them off, to at least give yourself a bit more breathing space, they simply overpower you as if you were nothing. Your shoves simply temporarily indented the balloons slightly, and nothing more. After rising for a bit, the balloons reverse course and you feel yourself descending back down. The impact is light, but you know your rubber cloud collided with the mattress.

Look at you, Ava's voice echoes all around the room, completely defenseless against those fragile toys. I can't believe a strong man like you can't get the better of a bunch of balloons. Is that really the best my strong boyfriend can do?

"If you give me no chance, of course I can't win!" But God do you wish this doesn't stop.

Your girlfriend giggles. Oh, I WAS giving you a chance, big boy. Here's what 'no chance' looks like.

With no further warning than this, the balloons surrounding you hisses loudly, the toys expanding half a foot in an instant. Which was followed by another hiss, and another, each time the balloons squeaks and creaks one against another as their rubbery hugs increases drastically, your male body getting hugged deeper and harder in their embrace. You half-scream, half-moan with each burst of expansion, once again trying to shove the encroaching latex away.

Huff, puff and surge, every balloons are over four feet wide, and there doesn't seem to be an end to it. Your hands seems to be sinking easier in the expanding rubber as time goes on, contrary to what you thought would happen from a balloon massively expanding. The way they cradle you in their squishy latex is pure bliss, your penis and your balls are trapped in what you can call a perfect latex sleeve, and still the balloons expands. You can't even imagine how two dozens balloons of those gargantuan size can fit in your bedroom, but this is Ava we're talking about. Obviously, she can make it happens.

At long last, the successive rapid burst of air and expansion ends, and you assume every single purple balloons around you are beyond eight feet wide each. You can barely move, the latex wobbles your body back into a neutral but very comfortable position whenever you try.

There. Isn't that better, sweetie?

"T-this is so wild... I can't b-believe I haven't orgasmed from all that..."

Ah, that's my doing. I wanted you to feel it all from start to finish. And since this IS the finish~

The balloons begins to wobble and the one around your penis and your testicles begins to gently vibrate. You throw your head back as, at long last, a new wave of orgasmic bliss consumes you. You feel your seeds ejaculating in the perfect latex cock sleeve sensuously milking you, releasing powerful moan with each strong volley. You don't even remember what orgasm number this is for the day, but just like your divine girlfriend promised, you can have as many as you wish, for as long as you wish, as strong as you wish.

After who knows how much time, you calm down, your penis spent for the time being, and a few of the balloons pressing against your face and your stomach retreats, leaving you slouched backwards on the comfortable wobbly balloon cloud. One of the balloons begins twisting and molding itself into an humanoid shape and, in a soft poof, your perfect girlfriend in her human form hovers a few feet in front of you.

"How was that, big guy, did I do good for my first time?"
