Aizawa knew he wouldn’t be able to resist them when he adopted them. His hybrid kittens were too damn cute to not think about Impurely, and on some level he knew that going into the adoption process. Here he was now, about two months into owning Denki and Hitoshi and he had his cock out, lazily stroking his shaft as he watched his kittens play fight in the middle of the living room. Soon enough they would be doing more than this, but he had to figure out how to approach their new training without them getting spooked. He knew he couldn’t just start with Hitoshi. The poor kitten was so skittish. Denki wasn’t that fast of a learner but was always eager to please. Aizawa would have to start off with Denki as the focus. There was one issue with that though. Hitoshi’s attachment to Denki. Aizawa worried that if he made Denki at all afraid that Hitoshi would lash out, hence why he had waited for so long. He loves his kitties. He doesn't want to spook them too bad and break the trust that took these two months to form.

He slowed his strokes and played with his tip, thumb absently fondling the head of his cock as Denki bit Hitoshi’s leg playfully. His head was so close to the cute cock, or even that plush little pussy Hitoshi had! If only Denki would just turn his head and realize what a treat there was right next to his face. How would Hitoshi react to the sandpapery tongue working his sweet little mound? Would he enjoy it? Would he pull away? Would Aizawa get the show of a lifetime?

“Denki. Come here.” Aizawa’s thumb slowed to slowly caress the side of his tip, almost not moving at all. He didn’t want to cum too soon. Not when he was going to finally take action.
His little Denki skittered right up and mewed cutely. Aizawa hadn’t taught them to speak just yet, and maybe he won't ever. Not when their mews are so cute. He doesn't want them to lose their little sounds in replacement of what had become the norm in society.

Standing up from where he landed, having slid a bit and hit the couch, the excited blond kitten’s bell jingled. All he wore was a collar. Same with Hitoshi. Once again this was something against the norm that Aizawa enjoyed about his kitten hybrids. “Be a good boy and climb onto daddy’s lap.”

Aizawa tended to be in full nude with them. Just another part of his perversion that allowed himself to give into.
Denki started climbing the couch and then into his master’s lap, causing Hitoshi to follow up behind Denki and sit next to Aizawa, leaning into him with a hand touching Denki’s leg. It seemed even after a couple months he couldn’t be too far from Denki. This probably has to do with their baths. The first time Denki was bathed Hitoshi had to be separated from Denki as Denki flailed in the water, screaming as if he was being killed when in reality his master was just trying to clean the flour off of him that he got into.

“That’s a good boy.” Aizawa’s hands settled on Denki’s hips. “Now you're gonna learn a new trick today.” He shifted Denki to be straddling a hairy thigh, cute little pussy pressed down on it. Denki didn’t seem to have any complaints about his omega parts being on his owner’s thigh so Aizawa continued while Denki tilted his head in curiosity, ear twitching.

One of the hands on the boy’s hip ran up his flat chest and to his jaw. He held the boy’s jaw fully in one large hand and leaned down, capturing his lips. The boy was confused, feeling daddy’s lips move on his own, but not knowing what else to do. On instinct he nipped at daddy’s bottom lip, thinking he was playing, but he only got a chuckle out of the man, no change. The man pet his hip so Denki began to purr, just happy to have his daddy’s attention. The more he leaned into the kisses he realized he was making daddy happy. His stick that was always between his legs or in daddy’s hand was leaning against Denki’s thigh, something wet beading at the little slit on the top.

Denki could feel this wetness when the thing poked at his side. Somehow that only made this confusing moment even happier for the boy. He was doing so good it seemed! Whenever wet stuff came from Daddy’s stick Daddy was happy!

Hitoshi wasn’t as happy. The adorable little pout he wore showed his irritation about not having Denki to himself. If he is going to be this cute about it, maybe Aizawa should take Denki from him like this more often. He waited, hand still touching Denki’s other thigh, but Denki wasn’t giving him attention. He huffed and watched as daddy’s mouth seemed to eat his brother’s mouth. It freaked the kitten out a bit but he was a brave boy! He could wait! Yeah… He could wait. Though he was getting more nervous the longer this went on. Denki’s purring helped soothe him though, allowing him to lay his head on their master’s side and wait like the good boy he so badly wants to be.

Something wet was pressing on his lips and Denki’s first instinct was to nip it, but it slid right into his mouth, making the kitten whine in surprise. It’s daddy’s tongue! It was so large compared to his itty bitty mouth, but something about it felt so right. His own little tongue licked on it, making the man chuckle into his mouth. Just as this happened, the hand on his jaw slid down to Denki’s little cock and slowly slid over it, cupping it and surprising the kitten yet again.

The cub’s first instinct was to close his legs, but he was a good kitten. He needed to let daddy touch him. Even if it felt weird. Oh gosh… It was moving on his thingy. It felt more than weird. Daddy’s tongue in his mouth and the three fingers that moved to hold the little kitten cock made him buck on the hairy thigh, little pussy rubbing on daddy’s leg and only adding to the overwhelming sensation. There was no slick. Denki was a bit too young to make any just yet, but as he got older, Aizawa looked forward to a slicked up thigh among other things. This got Denki in quite the cycle. He squirmed to try and manage the overwhelming feelings, but it only added to them. Daddy’s kisses got deeper, but Denki’s only got messy.

Hitoshi sat up, worried about his bonded brother, mewing in worry. That’s when Daddy pulled away, looking to Hitoshi for a moment before looking to his blond kitty with the most dazed look he'd ever seen. It caused a chuckle to rise from Shouta. He really did it. He made a move in training them. Finally, the real training is going to begin.

--------------------

“Come on. Show Hitoshi what you learned from daddy.” Aizawa’s cock was painfully hard, but his hands hadn’t gone back to it yet. He was helping Denki sit up in Hitoshi’s lap next to him, watching the kittens nuzzle. Hitoshi was just glad Denki was okay. He tends to be a worry wart when even slightly separated from his Denki.

He waited for a moment, watching them cutely mewl for each other, Shinsou’s fluffy tail wrapping with Denki’s skinner looking one. He got a bit bored of waiting and cleared his throat. “Come on Denki. Show him what Daddy was trying to teach you.”

Repeating his words got Denki in action. Poor Denki was still a little unclear on how this all worked, but after looking to his owner he leaned in and pressed his lips to his brother, mixing in little licks with his kisses, unsure of when to add the tongue, but eventually he melted into it, Hitoshi whining into the other’s mouth as he wasn’t sure what to do. Slowly he figured it out and copied his bondeds movements with a slight delay.

Aizawa sat up, hand unable to stay away from his cock. He was going to cum too fast and he knew this, but he couldn’t help himself as he watched his kittens make out next to him, Denki shifting in his brother’s lap and gasping softly as their little cocks rubbed together.

Poor Hitoshi whined into Denki's mouth, the feeling being too much already. It was barely anything Denki had gotten from their master, but it was already closing in on too much. At least too much for Hitoshi. Denki was actively seeking it out, grinding in the other’s lap, pride filling his chest as he hears their owner’s heavy breath. It didn’t matter to him that his sibling was trying to squirm away from the sensation. Not when he was chasing his own release.

Aizawa can’t hold much longer. He shifts to the side, legs tucking under himself so he can face his cubs, fisting his cock to their horny display. It was only moments until the boys were startled by hot white creamy stuff coating their side. Denki sat up, panting hotly as he looked down at both of their sides, the white dripping down their soft skin.

Shinsou looked at their owner with worry and gave a worried little mew. He was so flushed and still overwhelmed, even with his adoptive brother no longer rutting their groins together.

The poor fluffy tailed Shinsou looked dazed. It took Aizawa a moment to process what the cub was worried about. When he realized it he chuckled and shook his head.
"If you and Denki clean each other off extra good I won't make you guys take a bath."

This got Denki's attention. He stopped poking the warm cream and looked up at their daddy, alarmed for just a moment, terrified that he’s going to be in a tub full of that scary water stuff before he processed the man's words. He relaxed and gave a small rut in his brother's lap, earning a surprised little mew from Shinsou.

Aizawa pet Denki's head and spoke softly. "Make your brother feel good, and then clean each other off with your mouths. I'll go grab a cloth to help clean you down."

Aizawa got up, walking away from his shame that's coating his kittens. A bit of guilt cropped up as he worked on dampening a hand towel, but the sounds of mewls drifted into the kitchen and he couldn't help but feel a stirring in his loins again. He's right to do what he just did. Those cubs are his. They love him. He loves them.

He stood in the doorway soon with a warm washcloth, watching how Denki ruts desperately in his bondeds lap. The poor violet cub's toes curled as he began to sniffle between his mewls. His paws gripped Denki's hips as he tossed his head back, only a soft slick of clear wet trickling from the tip of his tiny cock. This was a bit of a surprise to Aizawa. He didn't know the boy could make anything. It's clear and thin, trickling instead of roping out, but it was so cute. His tiny immature barbs getting shiny with that wet he produced for the first time.

Somehow Denki didn't notice. He was lost in his own world. Denki’s head lolling back, pleasure being the only thing he can feel at the moment. His sibling is struggling with his first orgasm didn't alarm him. It just seemed like play fighting. This was something Denki was all in for, especially if it meant he could feel this way.

Aizawa walked over and began cleaning Hitoshi’s side, telling him he was doing so good letting his brother play in his lap. He watched as one of Hitoshi’s tiny hands moved between the barbed cocks, covering his own from being rubbed on anymore. The small barbs on Denki’s cock lightly scraped his bonded’s hand, but it didn’t hurt Hitoshi at all. It was just an odd feeling. Though what he just went through made it so that he didn’t really care. It was the least of his worries.

Aizawa bit his own bottom lip, washing up Denki’s side. Denki wasn’t even pulling away from the cloth. He just sat there humping his brother’s hand and trying to kiss him more but Hitoshi was too overwhelmed to kiss back anymore.

Giving a click with his tongue to get Denki’s attention, Aizawa took his lips in his own again, making out hotly with his blond kitten as Hitoshi recovers from his dazed state. Denki didn’t have long left, thighs shaking when he mewled hotly into his daddy’s mouth, hips bucking as he came dry, only a bead of clear leaving his tip.

--------------------

Pride was probably not what he was supposed to feel, but it’s what was there. Pride and arousal. Not just that he found them making out and with hands fumbling to try and find out what made them feel so good again, but that Hitoshi was the one who initiated it. At least that’s what it looked like.

Aizawa had just gotten home from a long day of teaching. He was looking forward to trying to train his kitties to kiss again, not expecting to see his babies on their livingroom kitty perch, Hitoshi on top with his hand between them, kissing Denki who seemed more than excited, actively bucking into the other’s hand. He had only gotten them to do this a few more times, so to find this waiting for him when he got home was one of the best gifts he thinks he could ever get from his babies.

Aizawa walked over, dropping his bag beside the couch, shoes having already come off at the door. “Such good kitties.” He reached up on the perch, petting Shinsou behind the ear as he praised him and gave a kiss to Denki’s cheek. “Want Daddy to help you boy’s out?”

He didn’t wait, lifting the omega Hitoshi up and off of his brother, his body moving before he could decide what he was doing. He set the cub beside Denki and moved Denki onto his belly, both of them panting and watching curiously. “Present, baby.”

Denki was confused, but when their master lifted Denki’s rump he kept it lifted, tail swaying and swirling around excitedly. He was such a good boy, behaving for daddy. Aizawa looked to Hitoshi and smirked, hoping this would work, cock stirring excitedly in his pants.. “Give Denki his kisses here.”

Hitoshi’s eyes followed to where daddy pat, the plump pussy his omega sibling owned. “It’s going to make Denki very happy and give him that feeling you both really like.”

To Aizawa’s disappointment, Hitoshi looked unsure. Aizawa wondered what he could do to convince him. Sweet little Denki was kneading the perch in anticipation. He likes it when daddy’s leg and hand rubs on his pussy, so maybe kisses there will feel just as nice!

Aizawa knew he should have shaved. The stubble was going to spook Denki, or so he thought. He leaned in, licking slowly over Denki’s omegan hole, loving the way the kitten shivered and whined. For a moment Aizawa was glad that Hitoshi hadn’t gone for it. He loved the taste and pondered keeping it to himself as he began to eat at Denki’s too tiny hole. Aizawa hasn’t been able to get anything in there just yet, though he has thought about testing out a pen cap.

Hitoshi nudged his owner’s cheek, growing jealous over how much the man seemed to be enjoying himself. The moment Aizawa lifted his face away from the mewling Denki’s plush pussy the other dove right in, lapping and kissing at the entrance with vigor, causing Denki’s mewls to grow loud. Aizawa had worried about whether Denki would enjoy the sandpapery tongue or not. Obviously the answer is a resounding yes.

Pulling back to watch and fondle himself through his pants he let his free hand slide under Denki to play with that tiny barbed cock. The poor boy didn’t know which way to press. Does he press back on Hitoshi’s face, or does he press down into daddy’s hand? The poor thing can’t make up his mind.

Aizawa watches how Hitoshi’s beautiful fluffy tail sways quickly. He’s not being touched, but his cock is leaking slowly, it’s wet marking the perch under him. If there was an alpha in the house, it would go right for him. No matter the age of the alpha. Hitoshi’s wetness isn’t just on his cock. His pussy is slick. The boy is developing quite early. Aizawa wonder’s how he can help the boy feel good, though he supposes Denki’s body will be good for that as Hitoshi matures.

In another jealous act, Hitoshi’s hand tries to push Aizawa’s from Denki’s cock, so Aizawa lets go. The poor blond whines at the loss but quickly shifts back into mewls, Hitoshi doing his best to fondle Denki’s cock as he gives his pussy ‘kisses’. It’s the most beautiful scene Aizawa had ever seen. He contemplates on taking a photo or video, but he knows if anyone finds such evidence he would be in a world of hurt and separated from his kittens. Despite being a sexual deviant, he loves his babies. Fully and truly. He just happens to be a near constantly horny man with needs that only his kittens can fill. Who could blame him? They are the most gorgeous creatures on the planet.

Pretty soon though, he could tell by the puff of Hitoshi’s tail and his little sounds that he was getting irritated. He was horny and wanted to feel good. It was an easy guess for Aizawa. This is when he bit his bottom lip, trying to hold back from making things worse, but he had to. He gave in. After he shed his coat and shirt, letting the purple cub lap at Denki’s exposed cunt as Denki keens and whines, so close to cumming.

“Need to feel good, Toshi?” Aizawa asked, fondling his bulge. He knows what he's about to do might be a bit too much for one of them. It's not like anything would fit in Denki’s hole though, so that wasn’t really a risk. Thinking about it got him riled up though, pants coming off and being stepped out of, left on the floor for now as he pulled Hitoshi off of Denki. Toshi hissed at first, wanting to be put back, but as soon as Aizawa positioned him with his cock on the plush lips of the boy’s pussy, nature seemed to take hold. Hitoshi sought out friction, humping Denki frantically. Denki wasn’t mewling as loud as he just had been, but his kneading seemed to intensify.

Aizawa moved to the couch, pushing his coat out of the way for him to sprawl back and watch the show. He spit in his hand before stroking his cock with it, proud of the show they were putting on. His breathing quickened as he focused on the franticness of Hitoshi. How he seemed to be trying to orgasm as fast as possible. Such a cute kitten.

Aizawa sat up fast in alarm as a sharp pained yowl rang out from Denki, said kitten looking incredibly upset, but panting in a way like he couldn’t catch his breath. Hitoshi didn’t stop humping. If anything he grinded on to him harder… Wait.

Hitoshi wasn’t grinding anymore. He was fucking him. He was fucking Denki! Aizawa almost separated the two, but Denki’s inability to keep a steady voice as he is frantically fucked only aroused him more. Aizawa laid back, fisting his cock faster as he watched Hitoshi lean in and bite the back of Denki’s neck to keep him still. It works, calming the yowling kitten down. Soon those yowls shifted into broken moans and mewls, tail that had curled in pain slowly relaxing against the kitten behind hims chest.

Denki’s claws no longer kneaded the perch. They clung onto it for dear life as he takes a barbed kitten cock much too big for his tiny slick incapable hole. It’s a good thing Hitoshi’s cock leaks more than enough to lube him up. Sure the cock itself was small, it belongs to a kitten, but in comparison to Denki’s love tunnel, it’s much too big to think about getting inside of there, but somehow Hitoshi did it.

Hot ropes of cum shot out, splattering Aizawa’s stomach and chest as his vision blackened for a quick second, his orgasm intense as he watched his kittens ‘play’. He could only hope they would take to doing this as they did kissing.

Slick pools of not yet fertile kitten cum spooled into Denki’s hot kitty hole, dripping out around the invading cock and spilling onto their carpeted perch, sure to leave a stain. That was more than okay in Aizawa’s books. He hoped they would stain the perch to the point it looked like it came in a different color.

The dazed look on Denki’s face as Hitoshi pulled out told their owner that Denki had cum quite some time before Hitoshi. Even possibly around when he entered Denki. The blonde panted, seeming glad to get some air and have a break, but that didn’t last for long. The violet kitten’s tongue went back to work, eating Denki’s now filled cunt out since Hitoshi was curious about this fluid and hadn’t gotten a chance to try it before. Even through the overstimulation though, Denki kept his ass raised, ready to be used.
