Chapter 1 - But Not A Bad One

Akira knew getting into a relationship with Tae Takemi would lead to interesting things. After all, It was one of the main attractions he had to her when he first met her. Whether it'd be the punk clothes or the fact that she called him her little guinea pig, to say that she was hard to resist would've been quite the understatement to make.

However, one thing he didn't quite expect was to be bent over and feel his asshole as it was slowly fingered back and forth by his girlfriend/doctor as she applied a steady amount of lubricant to his inner walls.

It started off like any normal check-up. Tae was giving him some stuff to test and so on before she suggested they try something else out. Something that would require Morgana to not be in the room with them.

Thinking that he understood what she meant, he quickly placed his bag outside in the waiting room and turned around to see Tae prepping the examination table and a bottle of lube, nothing too out of the ordinary until she said two words that caused his nerves to stand on edge. "Bend over."

It was embarrassing, the noises that climbed their way out of his mouth as Tae slowly teased his prostate with her fingers. Akira was usually a relatively quiet person. However, the sensations going through him as he felt Tae's fingers travel deeper inside him was something he had trouble maintaining some sort of calm over.

"Ngh.... Nmmmph...." Akira mumbles to himself, face burning hot red as he feels Tae's fingers travel inside him all the way down to her knuckle and even beyond that. It wasn't like he wasn't consenting or anything like that. Tae always had a somewhat wild side to her, so whether he intended to or not, Akira wasn't as taken aback by this as some might've been. Still, after a long day at school and talking phantom thief stuff with the gang, he wasn't really expecting to end up in this position.

"Oh!...." Akira jumps slightly as he feels Tae's fingers press down firmly on a random part of his asshole, which causes him to stand on edge as his already rock-hard cock begins to ooze out a small stream pre-down the inner side of his thigh. In response, though, Tae only let out one of her usual chuckles as she brushed a hand across his rear.

"You ok, guinea pig? I'm not going too hard, am I?" Tae asks. The nickname she gave him rang through his ears as sweat beaded down his forehead and fogged up his glasses.

"N-No, you're fine." Akira choked out, trying to remain cool, calm, and collected; he was the leader of the Phantom Thieves, after all. But with someone as sly as Tae, she could see through him like a window.

"Ok, then." Tae responds casually, amused by her boyfriend's behavior to sound tough while she double-fingered his rear. "It's fine if I am, though. You can tell me." Tae adds on, leaning in close to whisper that last part into his ear and watch as he slowly shivered in place.

Everything seemed set. Beyond the relatively normal health of his asshole, Tae figured he was ready for what she had in store as she climbed up onto the medical examination table behind him.

It was no secret that she liked to experiment with certain things. Some on her guinea pig and some, surprisingly, on herself. And in this case, it was no different, just a little something something to tighten herself up a bit for when she and Akira went at it again. However, after applying the ointment, it led to a surprisingly fruitful discovery.

Something that she began to fiddle with as she steadied Akira to stay still as she reached down and undid her coat, letting her massive member pop free. All the while, her boyfriend remained completely unaware until she slapped her cock across his plump ass.

"Suprise!" Tae says playfully as she watches Akira slowly turn back to look at her newfound member. His face, what was already a burning shade of red, burned even more as a look of shock, yet also surprised excitement graced his face, exactly the reaction she was looking for. "To cut a long and boring story short, I was playing around with some stuff, and then this happened. I don't know the exact details of how long it'll last. It shouldn't be long, I think. But I figured a little pervert like you wouldn't want this to go to waste. As long as you're up for it, that is." Tae asks, despite holding the dominant postion over him, she knew better than to put things in places without asking.

The first thought that crossed Akira's mind was to say no. This was all coming at him fast, and he'd need some time to think about it. But at the exact same time, what was the worst that might happen here? He was already courageous enough to have her put her fingers inside him. And in a world of personas and talking cats, this wouldn't exactly be the weirdest thing for him to go through. And so, after mulling it over, Akira slowly looks up at Tae and says, albeit quietly, "Yeah, go for it."

Oh, shit, he actually said yes. Tae was slightly taken aback. She was hoping he'd be up for this. But one to ten, she was expecting a much different reaction than what she got. Still, if he was up for it, who was she to be the one to stop things now?

"Ok, then." Tae says, trying to hide the slight tremble in her voice as she turns her gaze down toward Akira's rear and her massive member lying between his cheeks. It was still pretty weird to see a cock coming from her, and now she was going to put it up her boyfriend's asshole.

Reaching down, Tae grabbed hold of it and pulled her hips back, giving herself enough room to slowly push the head of it up against Akira's lubricated rear hole. While a part of her wanted to, she knew better than to just shove herself right in. Past experiences with not-so-considerate partners had taught her all she needed to know. Still, the temptation was there as she began to slowly sink her hips forward, applying more and more pressure to Akira's rear in the process and causing him to take in a short breath of air through gritted teeth.

Slowly though, after easing herself forward hard enough, it didn't take long for Tae to finally penetrate, popping the head of her cock into Akira's asshole and causing him to stifle a quick moan that tried to claw its way out of his lips. An honestly adorable reaction if Tae herself was being completely honest, but she'd keep that to herself for as long as she was going along with this whole 'dommy mommy' routine Akira was into. 

But as she became accustomed to the immense tightness of Akira's ass, Tae slowly began to slide herself deeper inside of him, going inch by inch as she felt her boyfriend's rear tighten around her fierce and long length, nearly causing her to moan in the process before she managed to keep it trapped behind her lips as her hips finally came to rest up against Akira's plump own. 

"Fuck, you ready for this?" Tae asks, checking one more time to make sure her boyfriend was all for what was about to happen. And sure enough, much to her joy, he slowly nodded his head, giving her the go-ahead to slowly pull her hips back and slowly drag her cock back out from his ass until the head only remained trapped inside him. Then, without further notice, Tae suddenly and quickly slammed herself back inside, pushing some of her weight down on him in the process. Enough weight, as a matter of fact, that his arms soon went out under him, causing him to fall face-first onto the examination table. Luckily, though, Tae managed to catch herself by pressing a hand down onto Akira's head, a position that she was initially going to move out of, but after getting a look at everything, she figured it'd be best to just go with it.

But after she got herself settled in her new position, Tae began to slowly slide herself back out before repeating the same process all over again, slamming her hips back harshly as soon as the head of her member remained trapped inside of Akira. However, over time, she began to slowly speed herself up, going from a slow and steady pace to a much more rapid one in a matter of what felt like slow dragging on minutes. Not that either of them minded. It was a new experience for both of them. For Tae, it was the fact that she was actually fucking someone with a cock, and for Akira, it was the fact that he was taking it up the ass.

Although, between the two of them, Tae was having a much easier time having to only contend with the tightness of Akira's ass as it wrapped around her cock, while Akira himself struggled with the powerful rod of meat slamming itself all the way into him and bumping harshly up against places he never thought would be teased in the process, nearly edging him to his limit a couple of times as Tae's thick, cum filled balls came into contact with his in thick repeated motions of movement. The sound resonated out of the room as a result, ringing louder and louder as his ability to keep himself quiet became a rather quick losing battle.

"Ngh! Oh! God! Ngh! Ngh!" Akira moans as his body lurches back and forth, his already tight grip on the examination table nearly turned into a white knuckle hold that seemed fit to tear through the cloth beneath him if it wasn't for the fact that he was trying quite hard to keep himself calm. Although, it wouldn't take a genius to see how aroused he was.

"That's right, guinea pig! You like that? You like taking it up your slutty ass?!" Tae grunts, the flow of arousal going into her brain causing her to act almost more sadistic as she even went so far as to raise a hand above her head and reign it down across Akira's rear, spanking him hard enough to cause him to cry out slightly as his cock continued to bob back and forth. "Say it! Say it, guinea pig! Say that you like taking my cock!" Tae snarls, voice dripping with venom as it finally pushed Akira over the final edge.

"Y-Yes! I love it!" Akira admits, a little bit louder than he usually would've liked. But his orgasm just about to shoot out from his cock, he wasn't really thinking like he would've, espically as Tae sped up her thrusting even more in responce to his whorish moans.

"Fucking take it then!" Tae says as she slams her hips downward one more time, the final push she herself needs before her cock explodes into a hot and heavy orgasm that begins to coat the inside of Akira's guts with a gooey layer of sperm. A truly fascinating and enjoyable experience for the woman as she finally comprehended the sensations that came from a cock's orgasm.

At the exact same time, though, Akira's cock finally cums, spraying some final loads across the examination table beneath him as his face is pressed firmly against it.

Slowly though, the both of them began to calm down, with Akira's eyes slowly rolling into the back of her head while Tae began to slowly extract her cock free from his ass. Looking down, she felt a change begin to occur as she watched the sight of her member slowly disappearing in what could've only been described as a puff of smoke. "Huh, fascinating." Tae chuckles before turning back to Akira. "Hey, you don't mind if we try this again, do you?" She asks, hoping for a certain answer and getting it as Akira slowly lifts his hand up in a thumbs up.

"Well, guinea pig. I think you look pretty good, health-wise." Tae says as she helps a limping Akira out of her office. "Just, uh, make sure to get some rest and make sure to come by tomorrow with a follow-up." Tae adds as she watches as Akira nods to her and reaches down to pick up his bag, the cute little head of his cat poking out to meow at him as they then depart.

"It was nothing. Just another check up." Tae could hear Akira mutter under his breath, presumably toward his cat, causing her to chuckle to herself as she turned back into her office. What a weird kid. A cute one, but still pretty weird. 

Sitting down, though, Tae peered out a nearby and watched as Akira walked around a corner, still limping after everything that they had done. Perhaps they'd use more lube next time. In any case, just as she was about to turn away, Tae's eyes caught the sight of a bobbing blond pigtails following after him.

Wasn't that Akira's friend? Ann, right? Watching her walk down the street, a smile began to grow across Tae's face as she quickly opened the window and poked her head out. "Hey, wait up a second!" She calls out to the girl, who stops to turn around and face her.
