Megumi really didn’t need any more pets in his life, but one day when he was out training in the woods with his demon dog, it caught a scent that caused it to run out of his line of sight. After several minutes of calling out and whistling, Megumi gave up and started to follow it’s trail. When he found the dog feverishly sniffing in front of a large tree trunk, Megumi figured it had found some type of fallen bird nest. But when he walked closer, he saw there was a figure crouched in front of his dog, practically shaking in fear. He determined it was no threat and sent his dog back to its realm, in fear it might start a fight with this helpless creature. But even that couldn’t calm you down as you watched the lanky man approach you. He observed you to see if you had any rabies or a collar on, but there seemed to be no indication that you had an owner, and he knew for a fact that there were no houses in the nearby area.
Although it wasn’t how he wanted to spend his afternoon, he felt like it was his responsibility to bring you to the shelter. A pup as small and fearful as you wouldn’t last another week out here. So with much convincing on his part, he was able to get you to follow him to his car. He tried making you sit in the backseat, but by the time he slipped into the driver side, you had already crawled up to the passenger seat. Your back was pressed against the car door as you looked at him with wide eyes, still contemplating if you could trust this stranger. However, he held a hand out to you to sniff, and once you got familiar with his scent, you were comfortable enough for him to pat your head. It has been so long since anyone has treated you with this much kindness! You couldn't help but to curl into his touch as you settled in the seat. Megumi was taken aback by how cute you could be when receiving affection, but he didn’t let that distract him for long as he reached over and buckled your seat belt.
You must not be very familiar with cars, because once Megumi started accelerating, you were looking around in every direction as if expecting something bad to happen. He figured it’d be safe to roll down the window to relieve some of your anxiety, and you immediately stuck your head out to take in all the sights and smells that passed by you. The first time he looked over, he could see your hair flying in the wind in all different directions, and when a strand got caught in your mouth, he had to suppress a laugh. But a few minutes later when he was at a red light, he looked over to see your head leaned against the windowsill with your eyes closed and a calm smile on your face.
‘ Well that didn’t take long, ’ he thought. You seemed to really enjoy the sunlight against your skin. And Megumi couldn’t help but to think that he was about to take that away from you by dumping you off at the cold enclosed shelter, with its cement floors and chain linked doors. But there was no way he could take you in. He already had his own set of animals to take care of, even if they weren’t really of the companionship kind. You would just be another set of chores on his hands, and he definitely didn’t have time for that. So when he pulled up to the shelter and parked the car, he had to shake you awake to get you to open your eyes. At first you were stunned, whipping your head towards him as a lock of your hair fell to the middle of your face. All he intended to do was push it to the side, but you must've assumed this was him petting you again, and tilted your face till it rested in his palm. Megumi was once again stunned by your sweet smile as you looked up at him like he was some guardian angel, completely oblivious of what he was about to do.
‘ Goddamnit, ’ he thought, and pulled out of the parking lot to start heading home.

When the two of you arrived home, Megumi gave you time to explore the house and become familiar with your new surroundings before cleaning you up. You were absolutely filthy, and he figured that you must've been out in the woods for at least a few days before he found you. But after getting you dried up, you seemed to be more than comfortable in one of his sweatshirts, which fit very big on you. The best he could do for now was lending you a pair of boxer briefs, and soon enough you were already following him to the kitchen as he prepared dinner. You couldn’t seem to care less, but Megumi felt a little awkward by the silence in the room as you stared up at him in curiosity as he stirred his edamame. While his food was cooling down, he figured now would be the time to properly introduce himself. Pointing at his chest, he said, “I’m Megumi.”
When you tilted your head to the side in confusion, he repeated his name a few more times before something seemed to click in that small brain of yours. But when you spoke, all you said was, “My Gumi?”
He tried to correct you, but you just kept repeating those two words over and over till you had a self satisfied look on your face, happy with yourself for learning more about your new owner. Gumi gave up and dealt with the nickname, and the rest of the evening was spent with you sitting on the floor in front of the couch with your arms wrapped around your legs as you mindlessly looked at the tv screen in front of you. After some time, you seemed comfortable enough to curl up by his feet, and by the time he was ready for bed, you were already fast asleep atop his plush carpet. Gently slipping out from under you, he found a spare blanket to throw around you and headed off to bed.
---
More of your true personality started to show in the weeks following up to Megumi rescuing you. You were sweet. So, so sweet. But you could also be a real pain in his ass sometimes. Like the way you had to be near him at all times, nearly making him trip over you because you were walking so close beside him. Or scratching at the bathroom door as if you thought he was imprisoned. But still, all of that was nothing compared to the joy of coming home to an adorable puppygirl who acted like seeing his face was the best thing that’s ever happened to her. Sometimes when he’d enter the front door after a long day, you’d already be waiting just a few feet away, tail excitedly thumping on the ground. Or on days when Megumi was gone for what felt like forever in your dumb puppybrain, you would paw at his chest till he agreed to pick you up and take you to the living room where he could scratch the back of your ears.
There was one day where Megumi came home after fighting off a nasty special grade curse. He wasn’t able to exercise it, and the feeling of defeat was only amplified by the fact that his clothes were completely tattered. When he walked through the front door, he didn’t even have the energy to greet you, and instead trudged over to the couch to slump down and take what felt like the first breath of fresh air he’s had in hours. He could hear you whine lightly from the lack of attention, but something seemed to silence you when he peeled off his ruined shirt to reveal his sweat covered torso underneath. He looked down to see you sitting in front of his legs on the floor, shamelessly staring at his glistening chest with large black pupils. It was like you were in some kind of trance, and Megumi bent down to pat your head to break you out of it. However, the closeness only encouraged you to sniff feverishly at his chest, which he allowed for a few seconds before sitting back up. You crawled closer till your legs were between one of his and your chin was resting on his knee. He had his eyes closed as he languidly stroked your head, and all you could think about is how much you liked your Gumi like this. Of course, you liked him when he had more energy to pay attention to you. But you also like this version of him a lot. It was so effortlessly masculine, and the absence of his shirt only heightened the features you loved about him. Like his long lashes, sloped nose, delicate collarbone, long fingers. Long fingers that you wanted to feel in more places than just the top of your head. It was like there was this burning sensation crawling up to your chest at just the thought of him touching you more, but you didn’t know exactly where or how. You just knew you wanted more of him, and when the apex of your thighs met his shin, a sudden jolt ran up your body as you finally found the source of where this ache was coming from. Without even thinking, you pushed closer to it and started to move your hips against him. The tense but pleasant feeling it caused only lasted for a few seconds until your owner tapped the top of your head.
“Hey, stop that,” he said sternly with a furrowed brow. You pouted but ultimately moved so you were sitting besides his legs again. But still you wanted more.

Later that evening when Megumi was showering, he was too exhausted to realize he didn’t close the bathroom door all the way, and while the sounds of it creaking open were being drowned out by his music and the water running over his sudsy hair, you sniffed around till you found what you were looking for. Grabbing the towel between your teeth, you tore it off the towel rack before scampering to the bedroom. Gumi didn’t let you sleep on his bed, but on days when you really missed him, you couldn’t help but to curl up in his pillows and imagine if he was there to pet you with that soft smile he showed from time to time. Presently, you were hopping onto the bed, dragging the towel with you, and pushing it around with your puppynose till it felt like it was spread out to your liking. Holding down one end with your legs that were curled under you, you bent over and squished your cheeks into the cloth, feeling like Gumi was here to hold you. It started to bring back that one feeling from earlier, but that was put to a halt by a noise from across the room.
“Seriously? Give that back, pup,” Gumi said, but you were just excited to see him again. And this time his chest was even more wet, covered in water droplets from his shower. You wanted to lick it off.
Megumi stomped forward and reached for the other end of the towel that was nearly hanging off the bed, but his movement was stopped and he realized you were sitting on the other end. He tried pulling his side up at an angle, but your dumb puppybrain interpretted that as playtime, and you bit down on the cloth to start yanking with your teeth.
“Stop that,” he scolded, getting increasingly annoyed by this game he didn’t want to participate in anymore. You lost your grip on your mouth but that only caused the towel to be pressed more firmly between your legs as he continued to try to pull it out from under you. You didn’t realize how sensitive that spot was until you felt the towel being rubbed against it over your underwear. It was like electricity traveling from between your legs all over your body, and just when Megumi was about to give up, he was shocked to see your back curve up and your eyes roll to the back of your head. There were maybe a few seconds where he could’ve decided to stop this, but later he’d tell himself it was just the shock of seeing you react this way that made him keep the cloth pressed between your legs. In a matter of seconds you were whimpering into the air as you ground against the towel and felt a gush of wetness stain your panties, causing a damp spot on the towel that wasn’t there before. The feeling of your first orgasm was overwhelming, and you fell sideways onto the bed and passed out asleep, leaving Megumi utterly shocked from what he just witnessed.
---
He let you sleep on the bed that night while still keeping a respectable distance away from you. However, he spent a long moment looking at your sleeping form, your puppyears curled in front of your face and the shallow breaths you took. The sweatshirt you were wearing exposed your bare legs, and with one tucked over the other, it accentuated your natural curves. But he wouldn’t allow himself to travel down that line of thinking, and turned the opposite way and went to sleep.
However, the following day you were sitting out in the living room as you watched him from a distance as he got ready to leave the house. He noticed you didn’t follow him to the door this time, but focused on making sure he had everything he needed before going. He had opened the door, only to realize he left his wallet in yesterdays pants that were still sitting on the floor of his bedroom. The sound of the door closing was interpreted by you as him leaving for the day, and you paced towards the bathroom with a purpose. Grabbing what you were looking for, you made your way over to the bedroom and pounced on the bed, letting the towel drape over your entire body. You wished that your Gumi was here to pull on it like before, but you settled for curling it between your legs as you gripped tightly onto the other end. Intoxicated by the scent it gave off, you started to pull and grind against the towel till you could feel that same electric feeling between your legs. It felt so nice to be surrounded by something that was his. The only thing that could make this better is if it were actually him here, touching you in the places the towel was. So you closed your eyes as all of your thoughts clouded with just him, and the words slipped naturally out of your mouth.
“Gumi, mmmmm, gumi. My gumi, my gumi, my gumi, my-” your voice broke a little as you started to feel that high feeling from before. You continued to moan his nickname over and over until your voice could no longer keep up and your body writhed under the towel.
Megumi knew you were seconds away from cumming, and although a dark part of him wanted to stay exactly where he was in the hallway to keep watching your perverted act, he had enough of a moral compass to know that that was wrong. So with his fists clenched on either side of him and his cock sporting a raging erection, he quickly made his way to the front door and tried to forget about everything he just saw.

That following weekend, Itadori and Kugisaki insisted on coming over to Megumi’s place to meet his puppygirl. It was also an excuse for them to drink, but Megumi figured he could use the distraction. With the boys on the couch and Kugisaki pulled up next to it in a lounge chair, they proceeded to argue over every single trivia question that came up while you sat silently in the corner of the room watching. It took you some time to warm up to new people, but Megumi figured it wouldn’t be long till you were comfortable around his friends. But when Kugisaki spilt some of her wine onto Itadori’s hoodie due to her tipsy state, Megumi noticed your eyes became more alert as you stared at his friend who was currently peeling his stained clothes off to reveal his bare chest.
“Ew, you weren’t wearing a shirt under that?” Kugisaki grimaced, no longer feeling as apologetic.
“Well I didn’t expect it to get covered in grape juice tonight!” Itadori argued back before turning to his other friend. “Hey, do you mind if I borrow one of your shirts?”
Itadori asked that with an easy laugh but noticed that Megumi seemed to be focused on something else across the room. But before he could say anything, he curtly nodded his head and got up to walk to his bedroom. When he was gone, you started to crawl over towards Itadori’s direction. With your wide eyed expression and wagging tail, Itadori couldn’t help the blush that rose up his face as you made your way over to him.
Giggling like the drunken fool she currently was, Kugisaki said, “I think she has a crush on you, Yuuji.”
“She is really cute,” he couldn’t help to add, and he reached out a hand to pat your head. You melted into the touch, before putting one hand on the couch between Itadori’s legs to smell him more closely. The pink haired man looked down at you, feeling a bit intimidated by how close you suddenly had gotten. But with a smile on a pretty little face like that, he couldn’t help but to continue to pet you as you inched closer and closer to him, nearly stroking your cheek against his pectoral muscles.
“Stop that,” came Megumi’s voice from the hallway entrance. It sounded more serious than other times he had scolded you, and everyone in the room froze to look up at him. A few awkward seconds of silence passed before you got down and made your way over to sit on the side of Kugisaki’s chair. She ran her much smaller hand over your head as she shot Megumi a dirty look.
“She was finally warming up to us and you ruined it!”
Itadori felt a bit confused and flustered, but accepted the shirt that Megumi tossed at him before they continued their game.

When it was late and Megumi’s friends made their leave, he was still feeling some of the effects of the alcohol as he made his way over to his bedroom. You were already on his bed, sitting up expectantly with your tail wagging as you waited for him to settle in. However, he only looked at you from the doorway for a long moment, and you started to shift nervously in place before he started to make his way over to you. When he was standing in front of you, you leaned into him for a hug but one of his hands shot out to grab your shoulder and stop you. Your brows tilted down as you wondered if you made him mad somehow, but his other hand reached up to grip your waist. His thumb grazed over you as his hand traveled down the side of your body, stopping at your hips. He seemed to hesitate for a moment before putting it under your sweatshirt and shrugging it up to reveal the side of your panties. You looked down at his hand, anxious of what he would do next but instead it stayed in place as he said, “Do you like Itadori?”
You didn’t fully understand what he was saying, but you knew he said ‘like’ and ‘Itadori’, and you wanted to assure him that you liked his friends and he could invite them over whenever he wanted. So you nodded your head with a small smile, but that seemed to upset him even more. He had a pained look on his face as he looked down at the hand that was touching your skin, “No, you don’t get it.”
His fingers slowly grazed over the cloth of your panties that was covering your mound. Every nerve in your body was shot but you didn’t move an inch as his fingers traveled down to your cloth covered cunt. Two of his fingertips ghosted over an area that was now throbbing but you held back your whine to let him speak.
“What I mean is, do you like him?” he asked and time seemed to freeze in that moment as he hoped that you understood what he meant. Hoped that he wasn’t going too far and he would wake up in the morning hating himself for the way he’s acted. You were so sweet and naive sometimes, it’s like you had no clue the effect you had on him. The effect you had on men in general. It stirred his insides with a mixture of rage and insecurity, which he knew wasn’t a good combination. You were too innocent to deal with his stupid jealousy, and he was starting to feel like it was a mistake for ever letting you walk into his life.
His eyes shot open when he felt your hand wrap around his wrist. For a second, he was afraid you would push him away, but instead you gripped it lightly as you looked up at him with the most tender eyes.
“My...Gumi…,” you said with such certainty that Megumi almost felt like he had walked into a dream. But you held his hand close to your sex with your wide saucers staring up at him like he was sunlight itself. He couldn’t hold back any longer as his arms wrapped around you and your lips met his. It was sloppy and wet, but his mouth guided yours till your tongues started to slip in each other's mouths. His fingers grazed over your soft flesh underneath your sweatshirt, and soon it was being lifted over your head to reveal your bare chest. Megumi’s hands almost immediately went down to start massaging them as he started to kiss over your collarbone. Your reactions were so cute, and it encouraged him to keep going till he had you laying back with your legs hanging off the bed. He knelt down to the floor between your legs till his mouth was hovering over your clothed cunt, which had a wet spot in the middle. Without pause, his mouth hugged onto your covered clit and you writhed from the sensation it brought you. This was so much more than when you would hump his towel or pillow. It was the real him and you wanted so so much more.
But he could tell from this position that it was making your tail uncomfortable, so when he pulled away, he hushed your whining as he got onto the bed and sat with his back against the headboard. He leaned over to grab your hips and you squealed as he pulled your backside close to him. He maneuvered your legs so they were on either side of his hips and positioned your ass right in front of his heated face before he started to pull your panties down. You shivered slightly as the cool air made contact with your wet cunt, and Megumi was completely enamored by how much some kissing and heavy petting affected you.
The noises you made when he pushed your hips to his face were heavenly, and he gauged your every reaction to find out what you liked. Your face was hovering over his crotch, and you could see a bulge forming in his pants with every moan that passed over your lips. You nudge your nose at it curiously, and soon started pawing at his waistband to get a better look. Megumi pulled back and with a heavy breath he said, “You don’t need to worry about th-”
But you were already crawling down to him just to turn around and sit on his upper thighs. Megumi laughed at your insistence before shrugging his pants and underwear down to reveal his hard cock. You were drawn in from how wet the tip was, and before he could stop you, you started to suck on the pulsing tip.
“Fuck, pup,” he groaned as he rested a hand gently over the top of your head. You were slobbering all over him as you tried to catch every bead of precum that was dripping out of him. Megumi could watch this scene forever, but he wanted to please you as well. So with much effort on his part, he said, “Okay, okay that’s enough. Come over here, girl.”
You excitedly crawled onto his lap and the both of you jolted when your cunt glided over his shaft. Looking as if some type of fever took over your body, your arms circled around his neck as you started to press and grind your cunt onto him. Megumi felt like he could get lost in the feeling of you on him, and he whispered praises in your ear that encouraged you to keep going. “That’s it… right there… so good, so good for me… such a cute girl.” Soon, both of you were breathing too heavily to kiss and he was guiding your hips with his hands so that your clit could rub against the head of his cock at the perfect angle. He could feel himself getting close, but luckily your body was showing the telltale signs of climaxing as you moaned his nickname over and over. At one point you stopped and Megumi could spot a line of drool traveling down the corner of your lip. He grazed the pad of his thumb to pick it up and guided it into your mouth, which you sucked obediently. The last shutter your body gave before you came on him was all the encouragement he needed to push himself over the edge, spurting out cum all across his stomach. Your hips were moving sporadically, but just the sight of your Gumi’s blissed out face was the last thing you could coherently see before your eyes shut and you came hard on his lap. You both took a moment to catch your breaths before he noticed one of your ears perk up. Before he knew it, you were crawling down his lap and sticking your pink tongue out to taste his release.
“You don’t- I-” he was taken aback by how much you seemed to be enjoying the taste, lapping up every last drop and going over twice to make sure you didn’t miss a spot. When you were done, you looked up at him with wet lips and gleeful eyes.
“Good job, girl.”

“I don’t think she knows how to pronounce your name correctly,” Kugisaki said a few days later, watching you stare out the window before taking a sip of her soda.
“Yeah, I’ve gotten used to it,” said Megumi in his usual emotionless tone, but inside the very thought of you bloomed warmth in his chest.
“Can we call you My Gumi?” Itadori poked his head between his two friends as he reached for another chip.
“Absolutely not.”
