There lies a town at the edge of the woods. The town was fairly populated by people, and the woods had its fair share of wild pokemon as well. The humans we kind to the wild pokemon population and so the pokemon and humans got along well. It was thanks to these good relations that the children of the village could very frequently play in the woods without the parents having to worry. Though large in size, the woods had plenty of trails and landmarks so it was difficult to get lost. Even then, the pokemon knew better than to let the younger kids wander off on their own, so there was always supervision. The youngest of the kids would stick to a clearing within sight of town, playing games with each other and the pokemon. Sometimes these games might bring them deeper into the woods, in which each child would be accompanied by at least one pokemon. Hide and seek was there favorite game to play by far.

There was no better pair at hide and seek than a small boy and his best friend, an Umbreon. The two of them were fast friends as soon as the child was old enough to walk and play outside. They'd do everything together, eating lunch or play wrestling on the ground. The boy was too little to speak, but was pretty mobile for his size. His head was covered in wavy black hair and he typically was dressed basic, today he wore brown T-Shirt, a simple pattern of an Eevee's smiling face took most of the front. It was a particularly hot day, so he was pantsless, save for the diaper he would typically wear underneath them. It was generously thick, putting a fair waddle in his step. Smooth on the surface, they were built to maintain this shape no matter how soiled. His was clean however, having been changed recently by Gardevoir after a big mess. Protecting the toddler's feet was a simple pair of white socks and velcro shoes.

Umbreon and the boy were on the move, having just begun a round of hide and seek, everyone was scrambling off to their hiding places throughout the woods. This time it was a Sylveon's turn to search. Umbreon and his friend hurried to their yet-to-be discovered hiding spot. Near a stream was a bed of ivy surrounded by trees. A playful tackle from Umbreon one day had the both of them tumble down through the ivy where they both discovered an abandoned den had been concealed. The ivy hung over them like a canopy, concealing them from the seeker while giving them plenty of room to play around while they wait for the game to end. The floor of the den was composed of very fine and soft grass, so it was hard to get uncormfortable.

The two of them sat in silence for a moment, resting from their short journey. Though the two of them were friends, Umbreon's feelings for the boy never stopped at friendship. He cared for him a lot and wanted to be by his side as often as possible and just thinking about him made Umbreon feel warm inside. Within a year of know him, Umbreon was sure he was falling in love. He knew the child was young for a human, but he couldn't help his feelings. Their adventures and laughs together meant a lot to Umbreon. Umbreon walked up to the boy and kissed him on the mouth. He'd began doing this at least once when the two of them were alone. The toddler was shy about it at first but quickly warmed up over time, eventually coming to respond with a quick kiss to Umbreon's cheek. This time Umbreon struggle to break away from his kiss, and he knew that this time he needed to go further while they were alone.

The sudden sound of leaves rustling cause the boy to break away to crawl towards their den's entryway. He peered through the hole in the ivy, looking around for Sylveon who may have finally come close to their hiding spot. Umbreon knew this was a false alarm, as his ears didn't pick up the sound of any footsteps. He didn't let out a call to notify his little partner, however as he was too focused on the view. Umbreon stared at his little love in front of him, who continued watching through the ivy on sll fours. His butt extended behind him, the smooth and soft diaper enhancing its form. Umbreon really grew to enjoy this sight and admiring it now cause his heart to beat faster. Feeling the warmth rise to his face, the Umbreon could do nothing to stop his member from becoming fully erect. It throbbed and pulsed with every heartbeat and once it got to this point, there was only one way to deal with it. The boy was in the perfect position, Umbreon just needed to try not to disturb it. For once in his life, someone other than himself was going to bring him to an orgasm.

He gently and quietly creeped behind the child, a stealthy tactic their games had gotten him good at. On all fours, the child was a little smaller than Umbreon. He leaned his head down, giving his butt a few sniffs. The scent of only baby powder was a good sign that his diaper was fortunately still clean, which would make things much more simple. Umbreon opened his mouth and sank his teeth into the soft butt of the diaper to get a grip. He gently pulled at it just to pull it down enough, but it would not budge. He tried again a little hard, but the diaper's grip refused to give in. Finally becoming aware of the force tugging back on him, the boy looked back at Umbreon confused. Umbreon closed his eyes and smiled in embarassment, but he hadn't given up yet. With a few more aggressive tugs, Umbreon got a more than he bargained for as the audible ripping sound of tapes unfastening hit his eardrums. He fell back, the unfastened diaper flying out of his mouth and hitting the ground with a gentle thud behind him. The boy maintained his four legged position, the boy looked at Umbreon in silence. Even he knew his diaper only came off for a change, and Umbreon wasn't capable of giving one. Something like this would typically have the kid running, but he had nothing but trust for Umbreon and stayed put in submission for his best friend.

Umbreon took a moment to admire his new view. It was the first time he got to take a good look at his naked lower half. His butt stuck out behind him still, covered in powder. Beneath it was a set of balls that looked more like half a walnut shell, and his tiny uncut cocklet that was barely visible peeking out from behind them. Most importantly, was the little pink hole between his cheeks. It looked like a tight squeeze, but Umbreon was confident he could make it through. His cock was admittedly not too big for a pokemon his size and a pokemon's precum was amazingly slick. He got back on his feet and re-approached the boy, keeping his gaze on the sensitive butthole. Being his first time, Umbreon was excited but also nervous. He swallowed to quench his dry throat with a bit of drool. If his little love showed any sign of pain or discomfort, he'd stop and never try this again. Taking a deep breath, he finally mounted up and supported himself on the boy's back.

The boy was just as confused as ever. Was this a new game? Why did Umbreon need to take his diaper off? Suddenly he started to feel something poking around on his bare butt. It was wet and felt a little odd, but it was poking as if looking for something. Umbreon was leaned down, licking the back of the boy's ear in a reassuring manner. It kept him calm, but he still felt a little silly about what was going on. Finally, Umbreon's cock found its mark. The child let out a curious gasp as he could now feel the object poking right at his little hole. Umbreon gently prodded at it, letting his fluids wetten things up as he gradually attempted to work his way in. His pointy tip kissed away at the boy's entryway for a bit before it was finally coaxed into opening enough. A rush of excitement washed over Umbreon and he had to resist the temptation to try and immediately force his way in. The boy gasped in surprise, knowing full well something was going inside of his behind but he remained still. Whatever it was Umbreon wanted to do, the boy trusted his friend knew what he was doing. Once the tip was in, it didn't take much poking and prodding for the shaft to enter. That was until the girthiest part met his hole. Umbreon kept prodding, hoping the boy's anus would give in. After a minute, it was clear Umbreon would need to give it a bit of force. He held is breath, hoping this wouldn't hurt his delicate little lover. In an instant, he thrusted with a fair amount of force. The resistance his cock met had completely vanished, he had finally popped his shaft in down to the hilt.

The kid gave out another gasp. the sudden stretching of his little boy hole was a massive surprise. It didn't hurt, but he was left with a powerful cramping sensation as his anus remained forcefully open to its limit. Umbreon sat still a moment, knowing the boy's body would need a little time to adjust to its new guest. He savored the feeling of the toddler's insides against his member. Wet, warm and incredibly soft, the feeling was more than he ever hoped for. He could even feel the boy's pulse around his cock. Umbreon finally decided to test things out. Slowly, he began to pull out. The stretched mouth of the young anus gripped at his shaft as he slowly unsheathed until only the head remained inside. Now in reverse, Umbreon pushed, his penis slid back in to the hilt with significantly less force this time around. He redid the motions, slowly picking up the pace with each pump. The boy with his shrill little voice began to moan in his high pitched voice. He had no control over the sounds he made. Umbreon's loving was leaving him with an overwhelming sense of pressure in his body. He could feel warmth pushing out from his face as his eyes began to feel watery. He could no longer support himself with his arms and so his upper body slumped into the ground, his ass remaining hiked up. He began to drool, and urine would seep from his little cocklet it quick but frequent spurts. The air forced its way out his lungs in constant, audible moans and his tiny balls were being gently pelted by Umbreon's sack.

Umbreon continued his sex, fucking the boy's tight love hole at the maximum pace he would allow himself. He didn't want too much friction out of fear of hurting his lover. He was too far into it now and there was no stopping. He thrusted away, him and the boy's hips dancing together, rocking back and forth with every thrust. His tail waved up and down as he went. The air in the den stank with the churning of their sex, but Umbreon didn't care. He was finally united with his little partner and showing him just how much he loved him. All of these feelings and factors got to Umbreon a little to quick and within minutes, he could feel he was ready. With his final and hardest thrust, he pushed himself as deep as he could manage. He cried out as he began to unleash his best orgasm ever, moaning with every spurt as he cummed a generous amount deep inside the toddler. The boy could feel Umbreon's cock pulsing in him, as the hot and sticky contents of Umbreon's balls began to spill out into him. Umbreon breathed deeply, as his member slowly became flaccid. He pulled himself completely out of the boy, who fell over on his side, exausted and out of breath. Surprisingly, the child's hole closed fairly quickly, only a small amount of pokemon seed oozing out beforehand. The grass below the scene was visibly soiled with the frothy mixture they had produced during their sex. Fortunately the child's close remained clean, and his bare legs minorly dirtied.

Umbreon lied down next to his lover, smiling. Still red in the face and catching his breath, the boy was finally snapping out of the trance he had been in. He wasn't sure what that game was suppsoed to be. It didn't feel bad, but it was definitely nothing he had felt before. If Umbreon likes it though, the boy was sure he could do it again for his sake. Umbreon leaned down and licked the toddler on the nose. He smiled and quickly kissed Umbreon on the cheek, to return the favor he had forgotten to when they kissed before. Umbreon was happy it all worked out. He licked the boy's legs clean, and brought the discarded diaper over. The boy was smart and cooperated with Umbreon, allowing the pokemon to fasten the diaper onto him as best as he could with his teeth. He could only hope the sloppy mess he left inside his lover stayed inside for awhile. Humans might not pick up on the smell of pokemon semen, but the other pokemon in the woods would definitely begin to wonder why he smelled of it.

The hour had passed and the game was over. The pair begain to journey back to the clearing to meet with the others. Umbron was happy the hiding spot remained undiscovered, because he was certain the two of them would be spending much more playtime there.
