Ipzum had been preparing to eat a sandwich when a few knocks came to his door. Going to investigate, there was a simple looking package. He would bring it into the house, before opening it up. Inside seemed to be a single diaper. How odd, it must have been a joke from Skydmaz or something. He would put it on, since he felt like wearing one today, and carry on with his sandwich, unaware of the fate he had sealed himself into. Things would go fine for the first hour, but the second past that, the diaper would seemingly come to life, though would keep quiet at first, intent on gauging the reaction of their new host first. It was in the middle of Ipzum taking a stroll through the forest, as he didn’t have much to do these days. When suddenly, he felt his balls being fondled by… well he wasn’t sure to be honest. It was a nice and gentle fondling, sure, but he just wanted to know who was responsible. Though he should have been asking what was responsible, as he looked at his own crotch, and saw what looked like a cartoony face on his diaper smiling back at him. Before he could ask any questions, he felt his cock being tickled now that it was fully hard, and it brought him to his knees, giggling. Ipzum struggled on the ground, gripping at his crotch in some desperate hope to stop the tickling sensation, but it didn’t stop anytime soon. No, this sentient and possibly cursed diaper had him in its grasp, and it wasn’t about to give up that power until it was done testing him. Ipzum was rolling around on the ground, giggling harder now, but it was about to get a whole lot worse. He would only laugh harder, when he felt something going down his urethra and into his bladder. At the same time, although unnoticed to him, something went up his ass a bit, plugging it up. Ipzum thought he knew every place he could be tickled in and had gotten used to them all over the years, but he was proven wrong as he never thought about tickling the inside of his own bladder. His eyes went wide, as he screamed out in laughter. He thrashed about, trying to rip off the cursed diaper, but to no avail. It was as if it was a part of him, which in a way, it now was. As a last-ditch effort, he tried using some of his demonic magic to burn it off, but even that didn’t do anything. Tears filled his eyes, as he was crying from sheer laughter. He could feel his bladder begin to spasm violently. Mercifully, the tickling of his bladder stopped, but it was already too late. He was going to pee himself and there was nothing Ipzum could do to stop it. He just sat there, limp and exhausted, as he began to piss, feeling the diaper easily absorb it. This went on for about a couple minutes before he was done, and it was then when the sentient diaper made itself known. “Wow you have an impressive bladder, quite sensitive too!” Ipzum had to do a double take, just to make sure he wasn’t hallucinating again. Did his diaper just talk? Or did Tanax slip him some of his drugs again. The former would end up being the correct answer as the sentient diaper began speaking again. “Hehe. I’m Tuko, your new sentient diaper parasite!” Parasite? Well, Ipzum had to emit, this was a new one. A sentient, talking diaper, parasitic in nature no less. He sat up against a tree and looked down at the diaper, using his tail to push his belly up a little bit so he could see. The face on the waist band was idly smiling, looking back at him. As they made eye contact, Ipzum felt his cock being stroked gently, a far cry from what he experienced less than five minutes ago. It took the cyan imp a few minutes to think of anything to ask, but once he did, the two of them would chat back and fourth for the better part of an hour. He would learn that while the diaper was semi-permanently attached to him through some sort of magic, it would clean up any waste from either end, which was relieving for him to hear. He would also find out the parasitic nature of this diaper, that it would feed off his cum, and sometime his piss. That was fine for him though, he was always happy to have an orgasm after all. By the end of the talking, Ipzum felt he was teetering on the edge of an orgasm. While they had been talking, Tuko had been pleasuring him slowly. It was barely noticeable to the fluffy imp until now. He danced around, hopping from one leg to the other in order to try and shake away the feeling, but this only pushed him off the edge completely. He felt his legs go wobbly as he came with an accepting sigh. His orgasm lasted only a minute and left him feeling tingly all over. Afterwards, he would make his way back to his house, and stumble inside, feeling Tuko pleasuring him again. He’d just barely make it to his bed before the sentient diaper went all in. It was like being given a hand job by a pillow monster, and Ipzum was all here for it. Sure, he was squirming around due to his cock feeling strangely sensitive now, but he was still enjoying it. If the horny imp had been able to look at the crotch area of his sentient diaper, he would have noticed a meter, and it was steadily rising, until it hit the top and the heart above lit up. At the same time, he would cum again, kicking his legs around as his body went tingly from the second orgasm. These orgasms seemed slightly more powerful than his usual ones, and it may have been from how long the buildup was. While Tuko was certainly pleasuring him a lot, he was still taking his time, having found the perfect amount of stimulation to make this imp spurt like a water hose. It was as fun for him as it was for Ipzum, who was squeezing his diapered crotch. Sure, it didn’t add anything to the pleasure, but he couldn’t help it. It was like trying to scratch an itch in an impossible to reach place. An itch now only Tuko could scratch. The sentient diaper decided to double its pleasure for Ipzum. It would mean a little less cum, but more frequent orgasms for its host, which it could tell he liked a lot. From this point, Ipzum’s mind would become a bit of a blur, orgasm after tingly orgasm left him giggling a bit, his now oversensitive member feeling the best it ever has. He was holding onto a pillow for dear life, humping into the air a little bit. He may be somewhat sad that he wouldn’t be able to stick his dick into anyone, but he wasn’t sure he wanted to anymore. This sentient diaper made him feel just as good, perhaps even better. If his mind wasn’t so broken from all the pleasure, he may have remembered that it was semi-permanent, meaning he might be able to take it off if he convinced it to allow such. Ipzum closed his eyes, continuing to hump the air as he felt a rather large orgasm approaching, one that would likely have him fall asleep afterwards, but one he would enjoy all the same. He clenched the pillow tightly, he was right there at the edge ready to gush, to empty his pent-up balls. All he needed was a little push, and he would cum like a fountain, though the mess be contained. He kicked his legs, thrashing around as his body began to tingle. The sentient could keep him on edge like this forever, but thought he earned it. After all, he had been cooperative after minimal convincing. With a firm but gentle squeeze from Tuko, Ipzum’s eyes rolled to the back of his head as he came hard. White hot pleasure burning throughout his entire body, leaving him limp as he could do nothing but enjoy the intensity of it all. This orgasm would last a solid three minutes thanks to the diapers magic, before it started dying down. By the end of it all, Ipzum was more tired than he thought possible, and just laid there, completely still. The diaper was still massaging his cock, but it was with a gentle care behind it. “Hehe. Goodnight ‘Ippy!” The diaper would say, but he was already fast asleep.
