Sylveon stood in the driveway, a beaming smile on his face as we haved goodbye to the car that vanished in the horizon. The vehicle out of sight, Sylveon pranced happily to the front door of the cozy house. He gently nudged the door shut behind him with a hind paw as one of his ribbons extended to the knob and clicked the locks shut. The fairy type hummed to himself, approaching the sofa on the other end of the living room. Raising his ribbons onto the sofa, he grabbed something. Extracting the baby boy that slept on the cusions, Sylveon lowered him to the floor. "Wake up, my little sunshine!" Sylveon sang out, using a paw to prod at the cushiony front of the little human's diaper. The baby let out a little yawn, clenching his fists and blinking the water from his sleepy eyes. He did not cry from having his nap disturbed, the pretty pink pokemon's presence always soothing to him. "Mom and dad are gone for the entire week!" Sylveon said with excitement in his voice. He walked circles around the infant who lay on a blanket on the floor. "Just as I predicted, they saw what a good job I did taking care of you last time they left and now they're off on their first vacation since you were born." Sylveon began to daydream. "It hasn't even been a year since the day they brought you home, but it feels like a lifetime. Since I saw you for the first time, I haven't been able to stop thinking about you and your perfect little body..." Sylveon looked back at the infant and licked drool from his lips. "Well, we may have a lot of time but I have even more ideas. So I think I should just go ahead and get started!"

Sylveon planted his butt on the ground, sitting right above the baby's head that rested on the floor. He stood over the child, staring down at him with a hungry smile. With two ribbons, Sylveon slipped off the baby's shirt leaving him in only his diaper with a Wooloo printed on the front. Sylveon stood back up and stepped forward, his body now over the baby's. His throbbing cock dragged across the infant's face who attempted to suckle instinctively on its pointy tip. "Ah ah ah~<3!" Sylveon said teasingly looking back. "There will be plenty of milk for you in the future, but today we're gonna try something different." Sylveon, finally having guaged the right distance now began to slowly lower his behind down. The baby watched it approach: the pink tail raised, the balls between his legs and most importantly, the puckered pink anus between them. Sylveon planted his rear end firmly onto the infant's face, his butthole in contact with the suckling's lips. Sylveon gave his butt a wiggle, nestling the human's face into his ass as good as was allowed. The baby felt the soft pink skin against his lips and attempted to suckle at it as best he could. His lips massaged away and his little tongue tickled Sylveon's sensitive hole. Sylveon was bright red in the face, raising a paw to his mouth with a giggle. "My my... What a useful reflex you have..." Maintaining his squat, Sylveon looked around the room. He merely vibed for a moment, smile on his face as he savored the sensations. He looked down at the diaper the baby wore. He had really grown to appreciate them. Their fluffy and white appearance as they wrapped around a youngling's delicates were aesthetically pleasing The adorable prints they often featured were a nice bonus as well. He kneeled down closer to it, carefuly not to break his hole's contact with his little partner. He nuzzled his nose on the front of the diaper before giving it a few deep whiffs. The smell of urine and baby powder graced his nostrils and he continued savoring the aroma. The baby suddenly turned his head away fron Sylveon's tailhole and began to fuss. Disappointed by the lack of any milk, he gave up his suckling.

"Ok, ok. Shhhhh... we'll get you a bottle when I'm all done ok?" Sylveon said soothingly in the aby's direction. The sound of his voice seemed to calm him for the moment. "Now... let's try this." Sylveon thought aloud, moving forward slightly as he felt a breeze on his drool covered butthole. His member rested on the baby's diaper, which sank slightly inward under its weight like a pillow. He shifted his hips back, his cock now on the infant's bloated belly. Carefully, Sylveon managed to get his tip under the waistline of the human's diaper and pushed his way in. His cock was now sheathed into the padding, a slight bulge poking out between the child's legs. To Sylveon's surprise, it felt pretty nice. His member was comfortably sandwiched between the soggy, warm interior padding and the baby's smooth and chubby nether region. He could make out the spot where the infant's tiny genitals lie against his, the tiny little thing safely under his own. The urine left everything moist and oily, so Sylveon's next action came with ease as he began to thrust his hips. As his cock slid in and out of the diaper, Sylveon held a paw to his chest as he became washed with pleasure. He sped up, moaning at the slick sensation. He rode away as his balls dragged back and forth against the baby's navel and finally got to the part he had been waiting for. Sylveon's ribbons clutched the infant's legs like handlebars as he let his own body go. He could feel his dick pulse within the diaper as a generous load of cum squirted from within him. Spurt after spurt, Sylveon squeezed out everything he could.

He dismounted the boy, his member having retracted to its barely noticable default state. The baby seemed just as casual as ever, minding his own business. Sylveon couldn't help but feel amazed at the quality of the diaper. Despite the abuse it took, it looked just as good as it did before. Sylveon gripped its waistline with a ribbon, pulling it outward and moving close to peek inside. He was surpsied by the size of the goopy mess he made within. He couldn't even see the baby's penis, smothered and drown under the sticky semen. Many strands clung from the glob to the absorbant interior of the diaper, a thinner layer having smeared to it. Sylveon released his grip and the diaper quickly closed back into place. "Alright, little guy. Time to get you that bottle!" Sylveon said, happily making his way to the kitchen. He was happy to know the first of many bonding experiences went so well.
