For some time Luna has been indulging in her new Inflatables fetish, and one day she decides to expand on this with something new after spotting an ad in a fetish magazine: inflatable diapers.

Do I even have to put warnings for this?

Luna's Inflatable Fun

Luna was a princess, which meant she did not sneak around like some filly secretly attempting to steal from the cookie jar. And yet, Luna was currently walking down the halls as stealthily as she could manage, excitement welling up inside her as she trotted to her bed chambers with a recently delivered package tucked beneath her wing.

Luna couldn’t recall exactly where or how she had discovered this, but for some time she had been inthralled by a new fetish, that of inflatables. She had started with balloons before moving onto pool toys and other such inflatables, discovering very quickly that there was just something indescribably intoxicating about the feeling of the rubber rubbing up against her body as it grew bigger and bigger, squeaking with each movement as she rocked back and forth again and again… Just thinking about it even now was causing a stirring to grow in her loins, one that would have to wait until she was safely in her chambers with her newly acquired toy.

For about a week ago, Luna had been browsing the latest issue of Fetish Monthly (a magazine that she would fervently deny having a subscription to if ever discovered) when she had been drawn to an advertisement for a new product for inflatable enthusiasts: inflatable diapers, or “InflataDiapers” as the ad called them. While Luna had been aware of the existence of a diaper fetish, she had never considered engaging in it herself… until now that is, as the allure of the inflatable garment had been too much for her to resist and within the hour her order form had been mailed out. She had waited with building anticipation for it to arrive all week, and now the day had finally arrived.

Finally arriving at her bedchambers, Luna had dashed inside before slamming the door shut behind her, making extra sure that is was locked to avoid being discovered. Her guards had been strictly instructed that she was not to be disturbed under any reason, and a quick soundproofing spell ensured that any noises she made would be muffled to any passing ponies that happened to walk by her room. Once she was certainly she wouldn’t be disturbed, she licked her lips with anticipation as she removed the package from beneath her wing and practically tore into it with her magic to retrieve the treasure held within.

Just like the image in the ad, the garment did indeed look like an oversized white diaper, though it lacked any form of tapes and simply had holes for her legs, tail, and body. It was also made out of a rubber similar to that of a pool toy and had a valve on the front for a pump hose. Unable to contain herself a moment longer, Luna hurriedly pulled the garment up her legs and onto her rear end, carefully threading her tail through the back with a bit of magic as the bands sealed themselves around her waist, thighs, and tail.

Immediately Luna noticed that the diaper had a noticeable bulk to it even deflated, almost like she was wearing a rubbery pillow on her butt. Taking a few experimental steps, she was overjoyed to hear the diaper squeak with even the slightest movement, the bulky feeling already stimulating her aching crotch and tempting her towards an early release. The fun was only just beginning however, so Luna resisted the sensations in her loins for a moment longer as she retrieved the small air pump that had been included in the package. Plugging it into the little valve on the front, she flipped on the pump and waited for the moment of truth.

She didn’t have to wait long, as the diaper ballooned outward almost instantly, the feeling of the rubber expanding beneath her driving Luna absolutely wild as the tingling in her loins increased to a level she had previously though impossible, her wings shooting out and extending out to their full length in an unconscious response to such pleasure. Unable to hold herself back any longer, Luna plopped down onto her rapidly expanding rear as she thrust both hooves into her rapidly inflating diaper and began to rub herself to orgasm. The diaper continued to expand beneath her, soon lifting the princess up as it reached the size of a large beach ball and just continued to inflate more and more. Luna knew in the back of her mind that the diaper had been enchanted to keep from popping due to overinflation, but in the moment she didn’t care as she continued to rub herself silly, sheer pleasure filling her very being as she pushed herself closer and closer to orgasm.

With a thunderous cry that probably would have echoed throughout the castle if not for the soundproofing spell around her room, Luna came hard into the diaper, flopping over onto her back as the diaper filled with her juices and the lasting aftershocks of such a monuments orgasm rocked her to her very core. Panting for breath, Luna reached for the pump to shut it off, feeling that now was an ideal time to end her little fun time.

However, in her excitement, Luna had accidentally kicked the pump aside, and the long hose meant that it was now well out of her reach. She tried igniting her horn with magic to bring it closer, but the feeling of the soft rubber pressing against her marehood broke any concentration she could muster almost immediately. She attempted then to crawl towards the pump, but even the slightest movement caused the still expanding diaper to rub up against her, helpless to stop herself as she pressed her hooves into her diaper again and proceeded to rub herself to orgasm once more.

Hours passed as Luna became locked in cycle of orgasmic pleasure as she rubbed herself to cumming again and again and again, her sexual juices beginning to drip through the leg holes as the diaper reached its limit. And yet, Luna was far too overcome with sheer pleasure to even care. Eventually her seemingly never-ending cycle of orgasms proved exhausting enough that Luna finally passed out, her dreams filled with images of inflatable diapers as the short lived battery in the pump finally ran out, freeing Luna from her prison as the diaper began to deflate.

By the time Luna awoke, the diaper had shrank back down to its original size, but already that was causing a tingling sensation to build up in Luna’s crotch. Quickly removing the diaper, Luna realized that her numerous orgasms had pretty much destroyed the diaper and left her a mess, both it and her now coat below the waist soaked with cum. Discreetly disposing of the now ruined InflataDiaper in the trash, Luna sauntered off to the bathroom to have a very long shower before returning to her royal duties once more.

During all this, she was already making plans to order even more InflataDiapers and have another go with what had quickly become her new favourite toy. Perhaps she would even “accidentally” put the pump out of reach again and see just how long she could last…
