in my parents' home we had a foot pump made of red rubber. we used it mainly on holiday to inflate air mattresses.

one night i dreamt that a young teacher of mine, whom i admired very much, was pumping me up into a big round balloon with this pump. i think i had a valve in my navel through which she was pumping the air directly into my belly. this seemed completely normal to me in the dream. the dream was very strange. but it felt incredibly good, and i was very happy in this dream.

for the next few days i couldn't get the dream out of my head. so i looked for the pump and took it with me to my room. when i was sure that everyone was asleep, i started my experiments. of course, the belly button thing was nonsense - that only works in dreams. so i tried to pump air into my mouth first. but that didn't work either. putting the tube into my vagina didn't even come into my mind those days. i would never have done that in my younger days! so the only possibility left was putting it into my butt hole. hesitantly i tried that. at first the plastic nozzle at the end of the tube scratched me, so i pulled it out of the tube. then i managed to stuff the tube into the butt hole.

i pushed the pump down, but the hose immediately popped out of my bottom. i put it right back in, which was easy by now. to prevent it slipping out again, i pushed it in deeper. it felt strangely pleasant. when i was finally ready to pump, the section of the hose outside my bowels had become very short. so i spread my legs and sat with my pussy on the pump. as i lowered my body onto the pump, my pussy pressed into the soft rubber of the pump. at the same moment, i felt the air enter my colon and inflate it. this startled me briefly, but at the same time i was totally happy that the pumping was now working. it also felt kind of good, so i repeated the process.

it got even better with each pumping. at some point i had to stop because the pressure in my bloated colon was simply unbearable. i also had to fart an incredible amount afterwards. but at least air doesn't stink. so that we don't misunderstand each other: i have an aversion to dirt and i now always clean myself with an enema from the shower hose before pumping. although i didn't have an orgasm while pumping the first time, i found it incredibly nice and repeated the whole thing immediately the next evening and then every night after that. i got more and more confident each time i rode the pump and inflated myself. already after a few days i humped the pump like a bouncy ball. at the same time i inflated my colon like a balloon. my colon tingled nicely from being overstretched and my pussy juices lubricated the surface of the rubber pump while i rode it. at some point i had my first orgasm and it was wonderful. my orgasm seemed to emerge from the center of my overinflated hyper-sensitive belly and rolled in waves through my mind and my spasming body. since then i have tried many sexual games, but no sex partner compares to my old rubber air pump.
