Ren had heard about the clinic in Yongen-Jaya run by the infamous Tae Takemi. He'd been drawn to her after meeting her back at Lablanc a few days ago and wanted to see more of her, and jumped at the opportunity to go visit her clinic for "medicine" when Morgana suggested it.

"You have to make up some excuse okay, some reason for her to give you medicine okay?" Morgana had been sitting on the table in the attic explaining his master plan on how to get the special medicine off of the Doctor. Apparently everything going forward hinged off of what Ren could accomplish today. "Perhaps you could use your exams as a reason?"

"Maybe my sleep?"

"Whatever will get you that medicine okay. Just make sure she believes you and will sell you the medicine, okay? I'll wait here for you until you come back. Don't be too long alright?"

Ren nodded and picked up his bag, walking out of Leblanc. The clinic was only a street away, but even so he'd made sure to double check where it was using a navigation app. The Takemi Clinic was a small and shabby looking place, not one that would draw lots of people to it. In fact Ren wasn't even sure that most people knew about it in Yongen-Jaya. The inside of the clinic was empty too and no one was at the counter either.

Ren took a look around at the magazines that were on display and the chairs that looked like they had only been used very little. The counter was pretty clean as well with a well used chair sitting by the desk. Ren wasn't quite sure what to do, should he wait or should he call out for someone? He was given an answer when a young woman walked in from the back, behind the counter.

She was a young woman, probably in her late 20's or early 30's at least, with short jet black hair. She had a white medical coat over the top of a green dress that was incredibly tight on her body, revealing her nice thighs and curves. Combined with her choker and make up, she looked more like a goth roadie than an actual doctor. Yet Ren was clearly into it.

"Can I help you?" she said, sitting down on the chair behind the counter and pulling out a magazine from the drawer.

"Um, I'm here to see a doctor…"

"Okay, is this your first visit? Have I seen you before?"

"You have, at Leblanc, and yes, this is my first visit."

"Okay and what are you here for?"

"I've uh… I've been having nightmares. Maybe it's because of my exams but um… yeah I need some medicine for it?"

Tae looked at Ren, dead in the eyes for what felt like eternity. "Okay" she said, standing up. "Head into the exam room and sit down, I'll be with you in a moment" and she buzzed open the door for Ren.

"Okay I'll prescribe you some sleeping pills then, that should help you sleep better. Sleep is the best medicine after all. Which would you like, the sweet tasting or the bitter tasting pill?"

"Um, whichever I suppose."

"Okay, how about the stinky one? Just kidding, there's no such thing." She dropped her notebook on the desk in front of her and crossed her legs, looking at Ren. "Okay why don't we stop beating around the bush. You're not sick at all are you?"

"What? Yes I am…"

"I'm not as dumb as I look you know. After all those rumours started getting spread around I've only had patients coming in looking for a good fix."

"Are the rumours true?"

"No, of course not. I have my own license to make my own medicine but I don't make drugs or poison of the sort. I dispense my own original creations okay? Look I'll prescribe you some of it but I want something in return."

"That'll be a great help, what would that be?"

"You're a high schooler, looks like you're healthy enough, I want you to be my little guinea pig." Ren's eyes went wide. "Calm down, everything I'll give you to try will be safe. It's very rare and hard to come by a high schooler to try out these sorts of things, so to have you do it for me would be perfect for me."

Ren thought for a moment. He knew he needed the medicine for the palace infiltration but is it really worth it to try out this strange medicine from the doctor? She did look trustworthy enough, and if the rumours were anything like Ann or himself, they would be far from the truth. He nodded, deciding to go with it.

"Okay great." She stood up and went into the other room for a moment and came back holding a small plastic cup with some coloured liquid inside. "I need you to be completely upfront and honest about any side effects you might have, even if you think it isn't. I will record everything on my notepad and after 15 minutes you should be free to leave."

She handed the cup to Ren and sat back, her notepad ready. She looked at him expectantly, waiting for him. Ren looked at the cup in his hand. It was odorless and was an odd blue colour. Swallowing hard, he threw back his head and emptied the cup into his mouth, downing it in one didn't like the taste of the liquid, it was oddly bitter.

"Wow… I can't believe you actually drank it… You seem to be doing okay, don't look flushed or anything. How are you?"

"I'm okay, I don't feel any different, don't feel any temp- OH!"

He stopped for a moment as he felt warmth rush to his crotch. In his pants he felt them get tighter, as his cock grew between his legs. In a moment it was harder than it had ever been, painfully needing release.

"What? What's wrong?" Tae looked at him with curiosity and worriedness.

Ren's face went red in embarrassment. "Um, nothing… everythings okay…"

"Ren, you need to tell me everything that you're feeling okay. I can't let you walk out of here until I'm sure you're okay."

"It's fine, it's just um…" He went through all of the possibilities in his head of what he could respond with. Tae looked him straight in the eyes. She would have seen through his lies. "Um, I think the medicine gave me an erection…"

Taes eyes went wide. "An erection…? How is it, like a normal one or…?"

"It's really hard, like painfully hard…"

Tae chewed her lip. "Okay, open up your pants, let me get a look at it. Oh calm down, this is purely clinical. I just need to make sure the penis is okay, nothing more."

Ren was a bit shocked. He was getting more and more comfortable since spending more time with Ann but this was something new for him. Despite his embarrassment, he unbuckled his pants and opened them, pulling out his cock. The pair were shocked by the sight, it was harder and longer then Ren had seen it before. Tae looked in awe at the rod, struggling to believe that it belonged to a high schooler.

"Wow… Um, okay. I'm just going to do some small tests and write some notes. And I'll ask you a few questions, okay?"

Ren nodded, his face burning in embarrassment. Tae slightly touched the shaft and looked around at it, making notes and comments. Ren wasn't sure why but every touch from Tae felt like a shock of electricity through his body. Even a slight caress felt better than anything he'd felt before. He couldn't help but let out a groan at her touch.

"Is it… sensitive? I'll try to be more gentle in that case." She continued to write notes and touch Ren's cock. Unknowingly at some point she had wrapped her whole hand around Ren's shaft and started to jerk him. When she realised what she was doing she froze and looked up at Ren. The teen was just as confused as she was but had the look of lust in his eyes. "Oh um… sorry I think it might be a habit…."

"It's fine. You can continue if you like, would help me lose the erection before I leave."

"Oh… yes that sounds like a good idea, actually…"

She started moving her hand up and down, stroking the thick cock. She was firmer now with her grip and started to stroke with a slight twist of her wrist. Ren felt amazing, the added stimulation from the drug and Tae's technique sent jolts of pleasure through his body. His moans were more frequent now as the pleasure built up inside him.

Tae couldn't focus on her notes now, she was starting to become turned on by Ren's moans and the thoughts of his cock. The potential for this new drug of Tae's was unfathomable for Tae. She had originally made it as a drug designed to treat insomnia but somehow it looked to be doing the opposite and making the patient incredibly horny. Tae had to test out all the possibilities and try to refine it further and perhaps even market it.

She decided to finish off Ren as quickly as she could so she could get back to work. She was excited about the possibilities and candidates she could use… Perhaps she already could use some of her patients that worked down at the batting field down the street.

Ren's moans became louder and constant until his hips jerked upwards. Tae only had a moment to process what was happening before Ren came. White spunk erupted from his tip faster than normal. It coated Taes hand, spilling onto his pants and onto the floor. Ren came more than he ever had before feeling like he was in heaven the entire time. When he finally stopped he was a panting mess and Tae slowly removed her hand.

"Wow, that was a large volume. Do you normally cum that much? No? Well I suppose that must be another side effect of the drug. When you've sufficiently softened up you can clean yourself and head off. Thank you for today."

"Um, Tae? It's not getting any softer…"

Tae looked back at Ren's cock. It was still standing at attention and now covered in the creamy substance. Tae was in shock and instinctively grabbed the cock again and looked over it. "Does it hurt at all? Do you feel tired? Empty?"

"Nope. I feel fine, energised maybe. This drug is incredible."

"It really is…" Tae muttered.

"Hey Doc, you should try it out, see what it's like."

"I'm not sure it's ethical to experiment on myself with my own drug."

"And jerking off your patient is?"

Tae stopped for a moment. Ren was right, it was unethical what she had been doing and she would be lying if she said she didn't want to try it. It had been months since she had last been laid or even got a worthwhile orgasm, so after seeing what happened to Ren, she was more than a little excited to try it. The boy was now looking at her with an aura of confidence. The shyness and embarrassment was completely gone now, replaced by lust. She knew what he wanted, but she wasn't sure how much of it was affected by the drug.

She stood up and went into the back room and grabbed some tissues for her hand. Before she wiped the substance off she looked at it and gave a lick of it. The semen was sweeter than normal, and it was a lot more pleasant than the previous men she'd been with.

She knew she had to try this now. She grabbed a plastic cup, measured out the right dosage of the blue liquid and walked back into the examination room. She downed it in one gulp like Ren, who was now sitting back with his arms folded and a smug smile on his face. Tae sat there for a moment, slightly disappointed that she had no reaction until it hit her. Her folds became wet immediately and her nipples felt like daggers, pointing through her dress. She let out a loud gasp at the new sensations. Every slight movement sent pleasure down her spine. She took off her coat and tried to sit still, shifting in her seat.

She eyed Ren's cock again, standing straight up into the air. Ren was still sitting back, waiting for her to move in. She felt herself start to salivate when looking at and moved in fast. She licked up the entirety of the shaft, from his scrotum to the tip before plunging her mouth down on it. She sucked on the shaft with an animalistic urge, a need to have the cock as far down her throat as she could.

Ren grabbed her head and gripped her head, watching her do her job. She desperately needed his dick and he was more than happy to provide it to her. Needing more she lifted up her dress and started to play with herself with her left hand. She moaned around his cock which made Ren moan as well. This spurred her on even more, his rod now coated in her saliva, giving the sloppiest blowjob she'd ever given.

The drug was sending Taes mind into overdrive, she wasn't thinking straight, in fact she couldn't think straight. The only thing she could think of was the smell of Ren's sex and her desires. The taste of the leftover cum on Ren's dick and the salty taste of his bulbous head turned her on more than anything had ever turned her on before. She rubbed her clit and started to moan louder, her whole body started to shake and quiver. Her moans were suppressed by the dick in her mouth.

Her orgasm washed through her whole body, making her shake and cry out. Ren gripped her head even harder and thrust her down, refusing to let her up for breath while she came. When her orgasm subsided, Ren finally let her come up for breath. She breathed heavily, struggling to regain her breath. Her body felt like it was on fire and she needed more. Her makeup was a mess now, her mascara running down her cheeks and spit smeared around her lips and chin.

"Tae, I'm almost finished…"

Tae jumped back on the cock, eagerly devouring the rod of meat. Like Ren, her first orgasm had done nothing to slow the feelings she was going through. Ren grew more eager too, thrusting his hips up into her mouth. Tae took the facefucking perfectly, with no resistance at all. It wasn't long before Ren let out one final groan and shoved Taes face down into his crotch.

Ren blew everything he had into Taes waiting mouth. He coated the inside of her mouth with his cum. Tae did her best to swallow all of it but gagged at the volume. She forced herself up, catching multiple spurts of cum onto her face. She coughed and spat out some of the cum she couldn't swallow as Ren jerked the remaining cum onto her face. Tae's face was dripping onto her clothes and floor as she continued to regain her breath. Both of them were hot and sweaty, Ren now having cum twice and Tae once, yet neither of them were close to being done.

"I'm.. amazed. This drug is… I didn't expect such results…" Tae said through ragged breaths.

"I don't know about you Doc, but I can still keep going."

Tae stood up and unzipped her dress, letting it fall down to her ankles. Ren only realised now that she wasn't wearing any panties or a bra. The Doctor stood there, completely naked in front of Ren. Her chest wasn't as large as Ann's, yet still looked nice and shapely. Both of her nipples stood out and looked as hard as ice, and were complete with two piercings on each, matching the rest of her goth aesthetic. She had a small landing strip above her pussy that was glistening with her own juices.

She moved forwards and crouched down over Ren, grabbing his dick and lining it up with her entrance. She moved down a little more until the tip slipped inside, earning a small moan from Tae. She slipped further and further down, her warm snatch engulfing Ren's cock. Her juices spilled out onto the base of Ren's rod. He moved up his hands and gripped her tight asscheeks.

She leaned down and kissed Ren sloppily before pulling back and looking him straight in the eyes. "Fuck me" was all she said and Ren obliged. He slammed his hips up to meet hers. Tae rolled her hips back and forth, getting into a nice rhythm atop of Ren. She gripped onto his shoulders, surprised at the muscles she felt beneath his shirt.

The pair moaned in ecstasy as Tae brought herself up and down on top of Ren. Her warm snatch gripping Rens cock as tightly as it could. Ren moved forward and took her left nipple into his mouth. Tae moaned and grabbed his head, pressing it into her chest. She gripped his dark locks and moved up and down, doing her best to keep her pace.

Ren swirled the nipple around in his mouth, using his tongue to play with it. He definitely had a thing for piercings now. "Mm, isn't that a good little guinea pig? Do you like playing with my tits?"

"Oh god yes. Everything feels so good, your whole body, I need more of it." Ren put pressure on the nipple in his mouth, carefully teasing it with his teeth. Tae gripped Ren's hair tighter, signalling the sweet spot. Ren combined his teeth with the teasing of the nipple, adding extra stimulation to Tae's chest. Ren was starting to feel pressure from below, now close enough to cum but enough to know that if Tae kept trying to milk his cock for everything he had, he might not last much longer.

But Ren needed more, Tae was good at riding him but he wanted to rail Tae before he came again. He gripped Taes asscheeks tighter than before, digging his hands into her and stood up, holding her against him. Tae yelped at the sudden change, having had no warning at all. Tae wrapped her legs around Ren and held on as tight as she could. Ren moved over to the examination bed and placed down Tae on her back, Ren pulled out until just the tip and grabbed Taes pale thighs.

Ren slammed in again at full force into Tae, earning a loud yelp. He battered away at Taes pussy, making her scream and writhe in pleasure. Ren had no care for Tae anymore, as far as he could see, she was just a bit of fuckable meat, a means to give him the release he craved so badly.

Tae's whole body shook on the bed beneath her, her tits shaking, her ass clapping every time Ren slammed himself into her. Tae started to pinch one of her nipples, twisting the piercing in her had her legs wrapped tight around Ren's waist, begging Ren to keep his length inside of her.

Tae's back arched in pleasure she'd never felt before. She enjoyed this position with other men she'd been with, they always enjoyed playing with her piercings and watching them move, and it was a great way to make her cum. But something about this time turned Tae on to no end. Ren's vigorous fucking, treating her like an object and the combined effects of the drug she was on. Tae knew that there was no coming back from this, no other man would be able to bring her such a release like this ever again.

"Fuck me harder Ren, I need you all inside of me!" Ren's hands gripped so tight into Tae she screamed in more pleasure. She was sure to get a noise complaint from one of the residents near her and she was lucky if she didn't have a patient in the waiting room at that moment, but in the bliss that Tae felt in that moment she didn't care. The whole world could hear her fucking and she wouldn't have cared.

"You've got such a good pussy Doc, I could fuck this all day!"

"Yes, fuck it, fuck me all day Ren!" Tae started to get louder, her moans deafening in the small room. Her entire body shook and her eyes rolled into the back of her head as another orgasm claimed her. This one was more violent and powerful then the rest, making any noise she made indecipherable.

Ren laughed and ramped up the speed and intensity while the woman shook beneath him. He leant forwards and gripped her right breast tightly, using his index finger and thumb to grab the nipple and twist hard. Tae screamed again, arching her back before collapsing back down on the bed. She was barely functioning, instead just giving her entire body to Ren, letting him use anything he wanted of her. Ren looked and sounded like an animal at this point, slamming as hard and as fast as he could, his grunts sounding less and less human each thrust he forced into tae's snatch.

The pressure inside Ren's balls was building up. At the pace he was fucking in he wouldn't last much longer. "Tae, I'm close, fuck I'm gonna cum inside you…" he groaned as he got ready, Tae feeling even tighter as he spoke.

"Yes, fuck cum inside me baby…" Tae started to play with her breasts again and rub her clit, still delirious from her last orgasm.

Ren started to get closer, now apparent on his face. His movements becoming more erratic, more violent. "I'm gonna cum for you Tae, scream for me okay?" Tae could only nod in response, her eyes closed, now kneading her breast hard and vigorously rubbing her clit.

Ren's moans grew to shouts and with one final groan as he erupted inside of Tae's pussy. He slowed down as he filled up her womb, the warm liquid beginning to leak out as Ren adjusted himself inside. He pulled out when he was close to finishing, catching a few spurts onto Tae's midsection. He exited with a pop and Tae moaned when she felt the warm goo splash across her pale skin.

Breathing hard, Ren looked down at the sweaty, spit and cum covered figure of the pale goth doctor beneath him. She had a slight smile on her lips, her eyes still closed. It was the look of someone incredibly satisfied, completely in bliss.

"Ren… I've never been fucked like that before…" She slightly rubbed her folds, causing a bit of cum to drip out and onto the bed.

"That is one hell of a wonder drug… You look amazing…"

"Do you like me laying here, covered in your cum? I liked being covered in it. I like it leaking out of my nicly fucked and raw pussy?"

"Mm I love it. But I think I need more of you. Do you think you can go again?"

Tae opened her eyes again and made eye contact with Ren. She gave him a lustful smile and slid herself forwards, closer to Ren. Ren chuckled and shook his head. "Not what I'm after." Tae opened her mouth to question him but instead yelped as Ren gripped her thighs and flipped her over on the bed.

Tae was flat on her stomach on the examination bed, spreading the cum that was still remaining on her face and stomach all over the smooth foam mattress. Ren gave her a slap on each cheek which Tae returned with a moan. Tae knew what Ren's plans were now. Normally she doesn't partake in anal, despite her looks, she actually doesn't partake too much in kinks such as that. However with the drug still running through her system, Tae couldn't only grow wetter at the prospect. The idea of Ren's cock filling her up again, violating her insides turned her on to no end.

Ren pulled her ass cheeks apart and leaned down, spitting a large glob of his saliva into Tae's waiting hole. With his thumb he pressed inside gently, slightly lubricating the hole. When he was satisfied he gripped the base of his shaft and moved in close to Tae, pressing against the hole with his head.

Tae let out a loud and deep groan as Ren pushed himself inside, letting just the tip inside. Unlike Tae's pussy, her ass was tight, almost too tight for Ren's length. Tae gripped the end of the bed tightly, wincing slightly at the intrusion of Ren's meat. The leftover cum and Tae's juices gave Ren a natural lubrication as he pressed in, getting a third of the way inside.

He started slow, pulling almost the whole way out before plunging back in, pushing further and further inside each time. Tae hissed and gripped the end of the bed. She was tight, tighter than anything Ren had ever been in before. He struggled to fit himself inside as Tae gripped him tightly. "I'm almost in, shit you're tight"

"Oh fuck, go slowly. You're really fucking big." Ren eased himself in and out, going slowly while still pushing himself further in. After a few more thrusts, Ren had pushed himself entirely inside of her. "Wait, give me a moment." Tae took a few deep breaths and adjusted slightly, getting used to Ren filling her up entirely. She hadn't had anyone as big as him inside her ass before, it was a whole new sensation for her. She looked back at Ren and nodded, giving him the go ahead.

Ren started slowly but pulling out to just keep his tip inside before trusting fully inside. Tae called out each time he thrust in, her body jolting forward away from Ren's grip. He gripped her cheeks tightly, spreading them apart as he fucked her. He felt the drug starting to affect his mind again, the horniness edging him on. Now that he could access Tae's ass he didn't care about easing in. All he could focus on was his release.

He sped up, forcing his way inside of her. Tae screamed, her whole body shaking as she was slammed into. Ren became animalistic, he fucked Tae roughly, bringing himself closer and closer to release. Soon Taes screams turned into moans. She continued to grip the bed as tightly as she could. A part of her felt like she was going to break the bed if this kept up, but another part of her wondered whether Ren would break her first. He treated her like she was his plaything again, another toy to fuck until it broke. All rational thoughts left his mind as he pounded away at her.

"Oh fuck Ren, keep going. Fuck, fuck, fuck, fuck, fuck, oooooh fuck Ren…" Tae screamed. Ren pounded away, giving the occasional slap to Tae's cheeks. A bright red hand print was clear on each side. Tae's cheeks burned from the repeated abuse, yet her body craved more. She begged Ren to fuck her harder until he leant forward and gripped her hair. He bent over her and called out, his voice echoing all over the walls. He pumped the last of his seed into her.

Tae moaned as he filled her up a second time, before he collapsed on top of her. Ren struggled to regain his breath after his last orgasm, his whole body drained of everything he had, cum and energy. He pulled out of Ren, his cock finally going soft, and collapsed back onto the chair behind him. Tae took a few moments before she stood up and leaned against the bed.

"That was… some kind of drug…" Ren managed to get out.

"It certainly was. It wasn't what I had designed it for, but this looks to be a happy little side effect."

"Are you going to make more of it?"

Tae smiled, almost sinisterly. "Well of course. I have to refine it of course, see what else I can do with it. And you'll be happy to help me with that right?" She leaned forward, her face only inches from Ren's. "Isn't that right, my little guinea pig?"

Ren grinned and couldn't agree fast enough.

"Good. You'll have to use the bathhouse down the street to wash up unfortunately but make sure you come back at some point. I'll make sure to let you know when I've made improvements for it, perhaps I'll even give you some to take home for… personal use."

"Of course Doctor."

"And one other thing, next time, try and bring a friend." Tae said with a wink.
