Baxter, after being flattened, stretched, tied in knots, and generally handled like a rubber balloon, was exhausted, if he breathed anymore he would be panting hard.
'This womans is insane,' he thought to himself, she obvously didn't care about his well being, but at least she didn't seem to be able to cause him more than discomfort, that was something.
"Just a little more testing Baxter, then you will be free to return to your life, with a much healthier bank balance," Sherri grinned at him, making him uneasy.
The woman pushed a button on the wall and suddenly a large panel opened on the wall and a tall, wide dildo slid out on a platform. Sherri moved it closer to Baxter then began spraying it down with yet another unknown chemical until the entire, massive thing was completely covered with the liquid.
Baxter stared wide eyed at the giant faux phallus next to him, it was at least a foot taller than the table he was on, and he only guessed that table was around 3 feet from the floor, but the truly terrifying thing about it, to him, was that it was thick, huge tree trunk thick. it had to be thicker around than he was, it tapered a little, but was still a fairly blunt rounded tip. Fearing that the woman was going to want to insert it in him some how, he tried to move away, which would have been easier if he were not trapped in the room, and exhausted already.
"Now, now, don't be scared, it's only, barely a meter across!" Sherri said as she picked up the young, rubbery boy, he just couldn't seem to find the strength to fight this woman, barely managing to tremble as she effortlessly lifted him off the table and placed his anus on to the wide, round tip of the massive dildo, holding him there a moment to allow the liquid time to start working on his rear entrance.
"Please, please don't," Baxter pleaded, or tried to, his voice was very soft, probably from the lack of breath passing his vocal cords he guessed.
"Don't be silly, you're doing so well, best subject yet!" Sherri gleefully stated as she firmly pushed Baxter down onto the dildo, the substance she applied to it working to ease it into Baxters newly rubbery behind, among other things.
"NNnnnmmmmmnn!" Baxter groaned as loud as he could, which wasn't much, as his ass, and indeed his entire lower body slowly, and somewhat uncomfortably widened over the giant dildo, it had a small but noticable ridge under its tapered head, Baxter noticed when he was examining it, under that ridge the phallus was mostly uniform in size.
"Very good, elasticity is doing very well, proceeding with impalement," Sherri said as she pushed another button, and continued pushing Baxter down on to the dildo.
Baxter could feel not only his body stretching to accomadate this invader, but also a gentle warmth inside himself as the dildo slowly pumped more of the liquid it was covered with into him as he was pressed further onto it. He wasn't sure what it was doing, but he was glad it wasn't painful, if anything it was actually starting to be less uncomfortable, plesant even.
As he continued to be pushed down the smooth dildo, Baxter was feeling better and better, he was starting to moan, signalling to Sherri that the liquid was working, to which she increased the pressure forcing Baxter down faster, not all at once, but fast enough that the inches quickly disappeared into him, passing the ridged head easily.
Baxter stopped making any noise at all after the head of the dildo passed into him, his mouth hung open, his eyes were closed, his face in a silent cringe as he was now being force down at a faster rate, breathing unimportant to him at this moment, all he could feel was the incredible girth of the dildo, the liquid pumping into him, everything else was gone, all he could feel was his ass, no, his body becoming a sleeve to this massive instrument.
He lost track of time, nothing else mattered to Baxter while he was being impaled on that dildo, he could feel every little movement through it, the liquid slowing its push into him until it stopped, the smoothness of its surface, he could feel it spinning around in him, or was he being spun around on it? he wasn't sure, but he felt it turning inside him.
Eventually, he felt no movement, nothing, he knew it was there, but there was absolutely no movement, he opened his eyes, but something was odd, he wasn't looking forward at Sherri, or a wall, he was looking up, at the ceiling, he could feel his rubbery backside on the floor, so he knew he must be sitting down, but he couldn't move his head to look around.
"Elasticity perfect, 100%!" Sherri exclaimed excitedly, Baxter could hear her but not see her, until she pressed another button, making the ceiling into a mirror.
Suddenly he was staring at himself, Sherri was off to his side, but his reflection was a shock, he was sat on the floor or maybe the platform the dildo was on, completely impaled on the huge phallus, he couldn't move his head because the tip of it was exiting his mouth, and the ridge under it had his lips stretched tight around it, making a perfect seal.
Sherri rubbed a hand up and down Baxter's taut body, he would have moaned if he could, all he could do was roll his eyes, feeling like she was giving him the most sensual massage ever, making him leak, but it wasn't his cock leaking, this time it was his cavity, what would be his anal cavity, now his entire body, was leaking some liquid, making the dildo slicker.
"Thats it," Sherri soothed. "Now push up with your legs!" She told him, suddenly he had strength back in his legs, allowing him to push himself up off the dildo, as he did, his body shrunk back to its original size, making a loud slurp as he came off it. "Excellent! Looks like your rubberised body is 100% elastic, and the self lubing agent seems to have taken too, I think we are done testing now, we have your clothes just outside, and we will have your payment transfered by the time you have left the building." Sherri said as she put the dildo back away in its place in the wall, and started to leave the room.
Baxter, for the most part was trembling, he wasn't sure exactly what all had happened, he was frightened, and a bit excited, his strength had returned to him, but he felt, or rather knew, that what they had done to him was going to be permenant, he wasn't sure, but when he got off the dildo, he felt that he could have stretched more, over a thicker object, he wasn't uncomfortable at all, he even felt that he could get use to doing that more often.
Baxter followed the woman out into the change room, quickly dressing in his clothes, which felt odd, not bad, just different, like he could feel each individual fibre of the materials they were made with rubbing on his rubbery skin, it turned him on, luckily his underwear and his rubbery erection held his rock hard cock safely hidden. Overall, Baxter felt he came out of this pretty well, he probably didn't need to have to eat now, he guessed, seeing as he didn't really need to breathe either, he wondered what else he didn't need to do now.
Sherri, grinning at Baxters unfocused gaze, she knew that look, he was curious about what had changed, interrupted the boy, "Here is a list of what we know you do and don't need to do from now on, and what we suspect are the limits of your altered body." She said as she handed him a printed leaflet of the effects of the testing.
"Ah, thanks," He replied, still wondering, and trying not to think about how erotic he was finding his hard cock pressed against his briefs, or that he had a deep ache in his elastic, stretchy ass that was making his new self lubing ability work, he could feel his ass getting slippery, and even taste his personal lube at the back of his throat, it was a pleasntly sweet taste.
"Your payment has been transfered to your account, and that concludes our testing with you," Sherri said as she held the door open for Baxter to leave the examination area.
"That is, unless you want to make some more cash?" She grinned.
