Jeff didn't take long to think about what to do next, he thought that maybe he might want his dick back eventually, but also wanted a way to remove it. it then hit him with the idea of making his ass valve inflate his penis back into existence, and if he came, air would should out of his penis until his panty waist fully deflated, and he wouldn't be able to stop cumming air out his piss slit until he had no air in his waist and his rubber skinned ass and crotch were flat on each other, then his penis would go away again and his rubber panty ass would inflate back to normal. He also made the ass valve bigger so and of a dense rubber, so another mans dick would be able to puncture his tight rubber panty ass and if they came inside him, they wouldn't want to stop until they filled him with cum so much that the pressure made his dick pop back into existence and Jeff orgasmed it out. He then typed that just about substance put in his rubber ass would do this as he thought of having another man crawl up his ass and spurt out his dick back into a normal man, or gluing his rubber ass to a water hose and leave himself spurting for days. the possibilities were endless!
Jeff then pressed enter and waited for the changes to give him that sensation again. This time there was a rubbery moan coming from his ass valve as it changed from a pool toy plug to a heavy duty rubber cap plug, like that on an air mattress or a big inflatable. he leaned back and arched his crotch forwards as his anus swelled to about 3/4 an inch wide and the cap in him grew too. Jeff then felt a bulging in his panty crotch and could feel a lump forming, like there was something there but no dick still. it looked like Jeff's boner was struggling to break free of the rubber panties and making a large lump. he was pretty aroused already, and with a loud pop! from his panties the transformation completed.
Jeff was so aroused already so aroused, but he needed to find out how much pressure it would take him to pop a rubber boner out of his rubber lump of a crotch, giggling, Jeff slid his hand down onto his now completely rubberized ass checks and grabbed the rubber plug in his ass and flipped it open expecting himself to deflate, but nothing happened. like there was something else in there that made it a one-way valve. Jeff got up to look at himself in the mirror and could see his ass valve was wide open, there was nothing in the way between the hole in his butt and the other side of his panty crotch, Jeff stared into his anus hungerly wanting to fill it with something, or fist it, or shove another mans meat inside, He gaped into the void of his red rubber butt for a while and then remembered the pump he left at his desk. Jeff gleefully went back to his desk-chair and grabbed the pump, hooking it into his rubber ass and flipped the switch.
The pump whirred into life inflating Jeff's panty ass even more, the pressure making his ass and crotch bulge further and further out, Jeff felt more aroused by the second as his panties inflated, he felt like the crotch was bulging more after about 15 minutes than his ass was as he filled himself with air. He giggled and cried a bit from the increasing tightness in his crotch as he watched gleefully as the lump began to push more and more outwards, forming a shape like a long balloon at a circus, he felt two smaller bulges pushing out underneath of the giant balloon sausage that was his dick becoming his over inflated testicles.
Jeff's vision began to fade as he felt like he was going to pass out from the pressure in his panties as the long balloon began to shape itself into a massive 24" penis about 3 or 4 inches around fully erect and throbbing with balls the size of grapefruits, the pressure felt like it was going to give as the head of his dick formed, Jeff knew he was almost there, a few more pounds of pressure in his ass would be enough to make his balloon dick give way. Jeff's held his breath as the head of his dick fully appeared and formed a piss-slit, his penis was 30" inches long now and then suddenly, Jeff couldn't take it anymore.
His balloon dick hissed with air as his dick throbbed and wobbled, the air in him spraying out of his piss slit like cum. Jeff's eyes rolled back into his head as he felt his dick grow more and more, reaching almost 3 feet before air escaping from his piss-slit was able to keep up with the air from the pump. Jeff just laid there drooling on the floor with the pump in his ass and his dick spraying air like a balloon at a party. This orgasm was the best feeling he had ever felt in his life, and Jeff didn't know if he wanted it stop.
Thoughts raced through his addled mind of shoving other substances up his ass than just air, but for now Jeff just lay there unable to escape from his endless orgasm of air shooting up his ass and then spraying out his dick. Jeff lost track of time as laid there until the batteries of the pump died and Jeff's boner began to shrink, Jeff just lay there drooling as his rubber panty ass and crotch spurted all the air in his waist out of his dick. Is rubber ass and crotch met and went flat on top of each other right as his dick disappeared back into his panties. Jeff started to get up as he felt his rubber ass re inflate back to its original size like the way it was when he rubberized his panties. He then sighed and pulled the dead pump off of him and plugged his butt again. Jeff basked in the afterglow of his crazy out of this world orgasm for a few minutes before thinking about what to do next. After some thought, Jeff decided he wanted to...
