3rd Person POV:

Deep underground in a private, highly sophisticated military base laid a laboratory that belonged to one woman with an irrefutably infamous reputation. This woman's name was Dr. Mobius, a young woman with long green hair, interestingly colored eyes, and a mean streak that no one had any hopes of quelling completely, not even the resident pink elf.

Speaking of whom, Mobius was currently sitting at her desk, her eyebrows furrowed as she read a document handwritten by Dr. Mei. She let out a disgruntled sigh and took off her glasses, setting them on the table before she leaned back in her seat, pinching the bridge of her nose. 

The past couple of weeks has been nothing but a headache for the scientist with the unexpected leave from Dr. Mei, leaving the green-haired woman without much help as her colleagues were next to useless and she would rather die than ask her for assistance.

Thankfully for everyone at the base's sake and safety, Dr. Mei soon returned and Mobius was more than happy to chew her out for her sudden leave which the former was prepared for. It was difficult to earn back Mobius's trust after wronging her and the green-haired made that fact obvious by assigning someone to watch over her subordinate: that person being Y/N.

At first, she had no quarrel about who would take the job. However. as she read more of Dr. Mei's hastily scribbled, and often incorrect, reports, she had to wonder if the young man was actually doing his job.

Hissing to herself, she set out to confront the both of them.

Slipping her white lab coat around her shoulders and pushing her arms through the sleeves, Mobius left her lab with a visibly annoyed expression.

Everyone in the hallways stood clear out of Mobius's way, afraid of invoking her wrath or being "randomly chosen" to undergo the MANTIS surgery. It was better for everyone this way as the head scientist was not in the mood to deal with the annoyances and "lab rats" around her.

"Hiiiiii~! Mobius~!"

"Speaking of annoyances..." Mobius muttered to herself when she heard the voice of Elysia, an extremely cheerful woman that has charmed many with her good-natured, true-to-herself personality. "What do you want, Elysia?"

"Aw... Is there something wrong about best friends talking to each other like this~?"

"We are not friends, Elysia, and especially not best friends." Mobius scowled at the woman who simply giggled and shrugged off the otherwise rude remark, unaware that her friend had stormed away.

"I know you love me, Mobius- Eh?" Elysia looked around to see that she was alone in the hallway and almost missed the sight of Mobius's lab coat disappearing around the corner. Within seconds, the elf-eared maiden popped up behind the annoyed scientist with her usual cheery smile. "Anyway, where are you going~? It's not like you to leave your lab without a good reason."

"It's none of your damn business."

Elysia pouted a bit before gasping loudly. "Don't tell me, you have a date!?"

"..." Mobius turned around with a dry expression and simply stated, "No."

"Ehehe, of course, of course..." Elysia giggled and leaned forward. "Then, why don't you tell me already and stop teasing me~? Ah, you're breaking my heart-"

"If I tell you, will you shut up and leave me alone?"

"If I say yes, I would be lying to my best friend and I definitely can't do that~"

Mobius sighed and pinched her nose, wondering what she must have done for the universe to bring Elysia to her. In the end, she ultimately confided in said person.

"I see... So, Mei's been acting weird and you're going to Ms. Aisha to tell her to punish her, huh."

"...What? No, Elysia, were you even listening to me?"

"I was trying to but... Your eyes are too pretty." Elysia sighed dreamily, earning another aggravated hiss from Mobius as she rubbed the sides of her head out of frustration.

Soon enough, Mobius arrived outside Dr. Mei's office.

"(Hm... The door's looked.)" Mobius tried to push open the mechanical door but that worked as well as anyone would have expected.

"Hm... Maybe, you should use your I.D card?" Elysia chimed in.

"WHY are you still here?" Mobius glared at Elysia who replied by giggling.

"Is it wrong for me to help my friends?"

Mobius shook her head with another grunt and flashed her card, making the door beep in acknowledgment and the light flash green.

With Elysia behind her, Mobius welcomed herself in, expecting to see her subordinate inside and doing whatever it was that was stagnating her progress. However, instead of experiencing the satisfaction of being right, she was left in a mixture of disappointment and confusion when she found no signs of Dr. Mei.

Although, her perplexion didn't last too long as she noticed Y/N sitting at Dr. Mei's desk that faced toward the doorway, wearing his formal clothes and too focused on writing something to notice them.

"No wonder the reports seemed half-assed, Mei had the idiot do it for her - the only person who's as useless as Kalpas at office work."

"Hey, don't call Y/N names or insult him..." Elysia was frowning now.

Mobius scoffed and pushed Elysia aside, storming into the room and slamming her hand on the table.

"Lab rat. Where's Mei?'

"D-Dr. Mobius!? Why are you her-" Y/N tried to stand up but quickly sat back down.

"Answer the damn question, lab rat."

"She's, uh, busy with other things."

Mobius raised an eyebrow while, in the background, Elysia gave him a pair of encouraging thumbs-ups and flashed him a smile with similar intent.

"Busy?" Mobius repeated what he said. "What could be more important than writing reports for me?"

"A lot of things, really." Y/N whispered not too quietly as Mobius heard everything.

"What was that?" Mobius slowly leaned over the table and was about to grab him by his shirt but Elysia quickly intervened.

"Mobius, stop it. Shouldn't you be more worried about if Mei ran off again?" Elysia knew exactly what to say as her words were enough to reign in Mobius's temper and make her stop.

Without wasting another second, Mobius left the room but not before shooting Y/N one final glare.

"She's so lovely, isn't she?" Elysia smiled at Y/N who leaned back against the chair and let out a loud sigh of relief now that Mobius was gone.

"You've been dealing with her for years!?"

"Hehehe," Elysia winked at the stumped male. "She'll be a lot nicer once you get to know her."

"I highly doubt that..."

"Oh, you'll see what I mean one day! Bye, bye~!" Elysia waved at Y/N and turned her back to him, about ready to leave.

Your POV:

"Oh and, Y/N?" Elysia looked over her shoulder with a knowing smirk. "You and Mei aren't as stealthy as you both think~"

"H-How do you-"

Elysia cut you off by closing the distance and shushing you with a finger. She giggled at your shocked expression and winked at you, whispering, "Don't worry, I won't tell Aisha anything so long as you behave, understood~?"

You nodded and she smiled, blowing you a kiss before she finally left.

"That woman is going to be the death of me..." You let out a sigh of relief and leaned back in the chair when you heard the click of the door, closing your eyes to enjoy the silence. 

After a few seconds, you looked down between your feet where Dr. Mei had kneeled down before the duo's arrival, watching her suck you off and placing a hand on her head. "It's always her or you, Mei-jie..."

The mentioned woman was no longer silently deepthroating you and the sound of her slobbering all over your cock filled the room. Her head bobbed up and down your cock feverously, leading you to wonder how her glasses remained on her face while she sloppily sucked you off.

However, you didn't have time to think as with a grunt, you bucked your hips upward and shot a load down Dr. Mei's throat, listening to her soft moans and the sounds of her greedily swallowing every drop of your cum. The older lady pulled back and opened her mouth to show that her mouth was nearly filled to the brim before she audibly gulped and spread her lips to reveal that not a single drop hadn't been swallowed.

"Good girl." You whispered and ran your hand through her long, smooth purple locks of hair. 

Dr. Mei warmly smiled at you before she ran her tongue up and down your cock to clean you up, leaving small kisses. She was quickly getting into it with you patting her head - to the point where she closed her eyes, about ready to worship and rub her face all over your cock but stopped herself.

"I should get going before Dr. Mobius kills us both." Dr. Mei cleared her throat and began to get up until you grabbed her by her waist and pulled her onto your lap, burying yourself into her bosom as you nearly tore the buttons of her shirt off. "Y-Y/N, we can't do this here. Anyone could w-walk in..." She tried to scold you but she was doing a terrible job of acting like she didn't also want this with the way her body twitched and the soft gasps escaping her lips.

"Just a few minutes..." You mumbled, not really understanding what you were saying, but your hands knew what you wanted as Dr. Mei yelped when she felt you squeeze that pillowy ass of hers.

"F-Fine... Only a few minutes, g-got it?" Dr. Mei didn't know if you could even hear her anymore as you seemed to be far more interested in leaving small marks all over her breasts and groping her rear. Her hands gently pulled you into her warmth, urging you to continue, while she grinded against your cock, silently begging you to derail everything she had planned for the day by bending her over the table and fucking her until the sun went down.

You knew what she wanted and strove to satisfy as your hands grabbed her by those wide hips that your hands were used to and lifted her off your lap. With little to no trouble, you made her stand up before abruptly turning her around and bending her over the desk, knocking all the stacks of papers over. In any other scenario, Dr. Mei might have yelled at you or smacked you upside the head, but she was far too gone to give a damn anymore and whimpered, "H-Hurry up, already." while pulling down her pantyhose to expose her bare ass.

Taking her invitation, you lined yourself up and slammed deep inside of her.

"Oh~! F-Fuck, yes..." Dr. Mei moaned and grabbed the desk for support as you pulled and thrusted back into her warm, tight snatch. It didn't take long for you to find your rhythm and for the sound of skin slapping together repeatedly to echo off the walls, soon followed by the doctor's loud moans. "Yes, right there. Fuck, your cock is so big!" 

Her words spurred you on and your thrusts into her quickened, leaving her shouting for more and pushing back against you.

"Geez, for someone who wanted to get going, you're sure as hell enjoying this." You slapped her ass. "Does it feel good when I fuck you like this?"

"Y-Yes..." Dr. Mei whimpered.

"Louder." You slapped her ass again and pounded her deeper and rougher.

"Yes! I loved it when you bend me over and fuck me until I can't walk~!" Words of indecency spilled from Dr. Mei's mouth the more you fucked her into a moaning mess.

"Good girl." You grabbed her purple hair and yanked it, making her gasp and tighten up before following your silent command of standing up.

Dr. Mei's back pressed against your chest and you pulled her into a small kiss that she gladly reciprocated, pulling your hands to grope her breasts and grabbing the back of your head to pull you deeper into the kiss. The soft mounds were always pleasant to feel and so were the pink, perky nipples that you often toyed with.

You were about to continue until you heard a voice that never failed to creep you out.

"So, this is what you've been up to."

You and Dr. Mei froze, recognizing who the voice belonged to, and slowly looked to the door to see Mobius standing there with her hands on her hips.

"(...Shit.)" You groaned internally.

"D-Dr. Mobius, I can explain-"

"I've had enough of your excuses, Mei. We'll have our talk later. But, for now..." Mobius made her way toward the door before looking over her shoulder, directly at you. "You. Lab rat. Follow me. While Dr. Mei has to catch up with weeks of reports, you'll be responsible for assisting me."

You exchanged glances with Dr. Mei who looked just as apprehensive as you but she quietly motioned for you to just follow along. She grabbed your hand from the awkward, compromising position and squeezed it before whispering, "Dr. Mobius won't stop until she gets what she wants, N/N."

With a nod of understanding, you pulled out of Dr. Mei - silently choosing to ignore the soft moan escaping her lips - and fixed your clothes with her doing the same but with a crimson blush. 

Unbeknownst to either of you, Mobius was sizing you up until her sharp gaze rested on your semi-erect cock and she licked her lips. A faint blush crept up on her face that she swiftly pushed down to keep up appearances but the discrete manner in which her legs slightly rubbed together was worth more than a thousand words. To say the least, her sex life was about as impressive as her social standing and she was always left utterly unfulfilled by the shortcomings of her previous partners. However, the green-haired woman was listening in when you were fucking Dr. Mei and her expectations were set high by you.

You sighed when you were done cleaning yourself up and carefully followed Mobius out of the room, none the wiser about what she wanted or expected from you but simply knew that you would be in a world of hell. 

At least, that's what you thought as you dragged your feet and kept your gaze on the floor.

"Oh, don't be so gloomy." You flinched when Mobius placed a hand on your chin, tilting it upward to get a better look at your face. It was then that you noticed how inviting her lips looked and how truly well-endowed the head scientist was.

...

...

[Neuron Activated]

While your attention was elsewhere, Mobius took this opportunity to lean forward and whisper hotly into your ear, sending shivers down your back. "If you can do your job properly, then maybe I'll give you a... special reward~ How does that sound~? Isn't that what lab rats like hearing? You know... Now, that I get a better look at you, you're kinda cute, did you know that?"

"Y-Yes, ma'am." You answered. You had no clue which question you were answering.

"Aw, don't sound so stiff. You can call me big sister too if you'd like, I wouldn't mind truthfully."

"...Dr. Mobius-jiě?"

Mobius's eyes widened slightly as if a switch had gone off in her head and she immediately understood why Dr. Mei enjoyed hearing you call her that. Smiling to herself, she patted your face and walked off, leaving you floored by her strange behavior before quickly following behind her.

Timeskip:

Nearly a week has passed since Mobius caught you and Dr. Mei messing around, and, by now, you were growing used to her presence and how things worked with her. Surprisingly, you and she were getting along well enough that you both were on a first-name basis.

However, your sudden change in station did not go unnoticed by the nameless soldiers as many were left wondering why you would go from Dr. Mei to Mobius. Were you being blackmailed? Was there something that should be investigated? Did you get in a fight with the former? In the end, everyone accepted this peculiar swap and moved on with the latest gossip.

Well, almost everyone.

"Y/N, I need you to look me in the eyes and tell me the truth. Did Dr. Mobius blackmail you into working under her?" The person in front of you placed their hands on your shoulder trying to hold down, but you simply shook them off.

"Su, you don't open your eyes. Period." You raised an eyebrow at the gray-haired gentleman confronting you, looking about as scary as a box of kittens.

"Y/N, I'm being serious."

"So am I."

The older male glared at you as effectively as he could with his eyes closed but ultimately sighed after a few minutes of silence from you.

"Alright, fine. But, please tell me if she tries to do anything to you."

You resisted the urge to roll your eyes and nodded. "Fine."

"Thank you, that's all I'm asking." Su thanked you and finally left after what felt like hours of interrogation from the so-called enlightened sage.

You watched him leave until a message from Mobius caught your attention and you peeled your eyes away from the man's retreating figure. However, you looked back when you felt someone's stare drilling holes in the back of your head and recognized the pair of azure orbs meeting your gaze.

"(Kevin...)"

"..." The white-haired man stood at the end of the hallway where Su was walking with his arms crossed as usual.

You and him stared at each other before turning away at the same time.

The route back to Mobius's lab was practically ingrained into your brain and rather uneventful as it always was. The people wandering the hallways were well on their way to their destination and in no mood to act casually.

Taking your phone out, you paused to check out the message Mobius sent to you.

[Y/N, be sure to swing by Phyllis's place and pick up my order before coming to the lab.]

Shaking your head, you set out to fulfill Mobius's request and made a slight detour to Phyllis's makeshift shop. You still had no idea how she was able to get a license for all of this but simply decided to go along with the thrifty feline's shenanigans.

"Oh! Boss~!" Phyllis tackled you in a tight hug that you reciprocated with a small smile, patting her head.

"Hey, Phyllis. How's it been?"

"Hehe~" Phyllis giggled when she felt your hand scratch her cat ears. "Everything's been going well! How about you?"

"It's been tough, adjusting to Fire Moth's regulations and rules but I'm barely hanging in there... Hm?" You stopped petting her head and placed your hands on her hips, not noticing the crimson blush dyeing her face. "Have you been eating well? You haven't grown much." You asked, idly squeezing her hips without much thought.

"B-Boss... Y-Y-Your hands... N-Not in public..."

"...Huh?"

"I-I mean- Ahem!" Phyllis frantically pulled herself away from the hug. She cleared her throat multiple times and calmed her racing heart down. "W-What brings you here, boss?"

"Er... Right. Mobius sent me here, saying that there's something that you have for her?"

"Sister Snake? I don't remember... Oh!" Phyllis zipped away and returned with a marked package with an arrow pointing upward.

"Uh... Is this it?" You carefully accepted the package, noting how extremely light it felt compared to what you were expecting. "It's kinda light, isn't it?"

"Well, obviously! Huh, wait. Do you not know what's inside?"

"Okay, now I'm worried..."

"Ah, don't worry, boss! I can personally guarantee that it's safe! Phyllis-approved!"

"...That doesn't help and now I'm even more worried."

"Ah! Don't worry about it, boss! Anyways, I gotta get back to work!" Phyllis returned to her shop, leaving you alone, and smoothly transitioned back to taking orders.

With a shrug, you look down at the package, wondering what was inside but refrained from sneaking a peek. You didn't want to lose the decent relationship you shared with the snarky scientist since you believed that it was a miracle that she was being tolerant of you in the first place.

At that moment, you heard a ding from your phone, signaling that another message had reached you. Reaching into your pocket, you pulled out your phone to see that it wasn't from Mobius but rather from Dr. Mei.

"Huh? I wonder what she wants." You voiced your thoughts out loud and opened the message.

Timeskip:

The elevator ride you took down to the floor where Mobius's lab lay was quiet and eerily as not a sound other than the machine itself could be heard. When you arrived at your destined floor, you approached the door leading into her infamous laboratory where there was a button and a speaker. A few seconds after you pressed the button, a voice came from the speaker.

"Who is it?"

"It's me, Y/N."

Statics replaced the voice and the door opened for you, allowing you to step into the secured room. Waiting for you with a scaringly arousing smirk was Mobius sitting in her chair, her nylon-clad legs crossed in an alluring manner. You took notice of the pink, glossy lipstick she had applied today but your attention was focused mainly elswhere.

"What's wrong, N/N?"

Your eyes widened when you realized that you were blatantly staring at her thighs for who knows how long.

"N-Nothing, here's your package..." You hastily muttered and placed the package on the desk next to Mobius while she giggled at your flustered state. The voluptuously-figured woman uncrossed her legs and stood up, making sure you were watching when she slowly shed herself from her white lab coat and left you to gawk at the sight in front of you: Mobius wearing nothing but a pale cyan dress shirt and pantyhose.

Mobius began to open the package from Phyllis with her back facing you, only stopping momentarily when she noticed you watching closely.

"Is there something wrong?"

"N-No, of course not!" You shut your eyes closed and turned away to hide the dead giveaway of your...shall we say, excitement.

"It must have been a long week for you, wasn't it? You know, with the whole change in environment." Mobius's ominous giggling sent a jolt through your head as well as the one on your shoulders. "Maybe, I should start giving you a reward at the end of each week~? How does that sound? Do you want that from your lovely Mobius-jiě~?"

You silently nodded and approached Mobius as she pushed herself up onto the table, her legs hanging off the edge. She wiggled her toes before rubbing them against your erection, teasing you as she stopped you from freeing it.

"Is this what you like?" Mobius smiled at you upon seeing your helpless expression when you felt her feet on your crotch, having never experienced this. "Hoh~? Looks like Mei never did anything like this before, did she? Well, just know that I won't be as pathetically submissive as her, N/N."

You opened your mouth to say something but Mobius made you shut up by continuing to lightly step on your cock. Her feet smoothly ran along your legs and pelvis, gently rubbing against your erection with enough force to make you feel good but not enough to make you cum.

"How does it feel? Good? Amazing?"

"It's a little weird..." You stifled a groan when she placed both of her feet on your cock and jerked it off through your pants. It wasn't something that you were used but the confidence in her every move made it feel normal and good. "But, it feels pretty damn good."

Mobius smiled and continued to rub you for a few moments before she abruptly stopped. "Take it out." She commanded and you happily obliged and freed your erect cock from its confine, earning a coo from Mobius as her feet lovingly caressed and played with it. "Hm... It's almost unnaturally massive compared to most men that I've seen..." A harsh glare was suddenly thrown your way for reasons that you didn't understand. "You better not disappoint me as they did."

"I'll try my best." You groaned as her feet grew increasingly demanding of you and stroked your cock faster and faster. The tightness of their grip around you and the sweat on her feet made the new experience feel easier to get used to.

"You're not just content with a footjob, are you?" Mobius asked you with a teasing smirk before she moved a hand down between her legs and made a 'V' sign over her pussy under the pantyhose. The lower region of Mobius was soaked and stained the nylon fabric of her stockings. "You want to blow it in here, don't you~?" She laughed when she felt your cock throb and slowly pulled her feet away, pushing herself off the table. "We'll get there... eventually."

You opened your mouth to say something but froze when Mobius unbuttoned her shirt to free her large breasts held in place by her enticing brassiere. The black lingerie she wore tightly hugged her hourglass figure and complemented her pale skin, also emphasizing her perked-up pink nipples. To say she looked beautiful and sexy would have been like saying fire was hot and ice was cold.

"Why are you just standing there? This is what you want, no?" Mobius stretched her arms toward you, motioning for you to indulge yourself in her warm embrace. "Come~"

With such a tempting invitation, who could resist? Certainly not you as in the next moment, your vision was obscured by Mobius's breasts being shoved into your face with her pressing one hand behind your head to push you further into her bosom while the other reached down to jerk you off.

"There you go, good boy~" Mobius whispered into your ear and patted your head, encouraging you to continue thrusting into her hand. She let out a sharp gasp when you yanked down her bra and latched onto her nipple, but didn't stop you even when you slipped a hand down between her legs to rub her pussy. "Oh~? How naughty~" 

Hearing Mobius's words and sultry voice invoked feelings inside of you that Dr. Mei could never hope to do with the genuine love and care you shared with her. It was always tender and full of passion whenever you two made love as you couldn't risk the possibility of hurting her. On the other hand, everything you felt for the busty scientist was complete lust and simply your instincts telling you to do one thing: to fuck her until she couldn't think properly. To breed her until she was left a cum-filled mess. To pound her senseless until she couldn't walk for weeks- Your eyes widened at the flood of impure thoughts brought on by your instincts slowly taking over.

While you struggled to shove these thoughts away, you hadn't noticed the silent gasp from Mobius as she came, her fluids staining her already dampened pantyhose further. Mobius felt the desperation in your movement as well as the violent throbbing in your dick and smiled before suddenly letting go and pushing your head away, silently enjoying the confusion in your expression as you were denied your orgasm for the second time.

"Aw, don't give me that look. I decided that I wanted to try something else."

"But-" For the who-knows-how-many time this day, you were silenced by Mobius who pulled you into a kiss, wrapping her arms around your neck, while squeezing her thighs around your cock. Any hint of defiance inside of you melted away when you felt the melting warmth of her gorgeous legs. "(H-Holy shit...)" Your hips pistoned back and forth into her thighs, the heavenly tightness of her thighs made all the more alluring with her stockings and the wetness of her soaked panty through the nylon material.

"Feels good, doesn't it?" Mobius whispered to you after pulling away from the kiss, leaning down to leave small marks on your collarbone.

"Y-Yeah..." was all you could utter along with a series of groans as the speed put behind your thrusting accelerated when she squeezed down even tighter on your cock. Sneaking your hands down toward her shapely ass, you risked a chance to grope her rear to which she simply moaned but allowed you to continue as she grinded fervently against your cock.

"N/N, are you going to cum soon?" A nod from you was all you gave, too focused on fucking her thighs. "Good. If you help me first, then I'll make sure to finish in the most spectacular way. How does that sound~?" 

Perhaps, if you weren't so lost in your lustful frenzy, you might have realized what she was planning and rejected the offer. Instead, you dropped to your knees and tore a hole in her stockings before shoving your face into her crotch, drawing out sharp gasps from Mobius as you ate her out. Your tongue lashed wildly inside of her soaked pussy, making her moan from your unrestrained vigor.

"Mmh~! Keep going!" Mobius grabbed the back of your head to keep you in place, urging you to keep up your lewd services. "I'm almost-!" Before she could finish her sentence, Mobius's inner walls clamped down on your tongue, her back arched, and a wave of her fluids splashed against your chin. Panting to herself, Mobius tilted her head down to meet your needy gaze and wiped the drool trickling down from her mouth following her orgasm. "N-Not bad..." Mobius muttered under her breath and gently pushed your head away.

"M-Mobius-jiě..."

"Hm? Oh, right. You'll have to take care of that on your lonesome, lab rat." Mobius returned to her normal self in no time as the 'older sister persona' of hers vanished completely. "I got what I wanted and I see no need for me to help you with getting off. Your hand should be more than enough." She scratched under your chin and turned her back towards you, walking off.

A small part knew that this would happen after the second time she abruptly stopped to prolong your orgasm and you were slowly beginning to understand why so many people said the bad things they did about Mobius. To put it plainly: she's a complete bitch... Buuuuut... She was a hot bitch.

Despite this, however, were you content with leaving things like this?

Hell no.

You grabbed Mobius by her hips, much to her surprise, and yanked her back towards you, thrusting back wildly between her deliciously thick, nylon-clad thighs. Your large cock rubbed against her pussy while your hands roughly grabbed that fat ass of hers that you were eyeing up earlier. You were so lost in your thrusting frenzy that you tuned out the shouts of protest from Mobius as her plan was going awry with your sudden surge of lust.

"W-What are you- No, wait, this isn't how you were supposed to act!" Mobius was trying her best to make sense of this unexpected development but was now the one to be silenced as you slammed your lips against hers. She let out a muffled gasp when you slapped her ass and allowed you to slip your tongue into her mouth, exploring your newfound territory and making her moan with the roughness with which you control.

With one final thrust between her thighs, you blew your load all over her desk and papers. You knew that she would kill you later for that but forced the thought to the back of your mind.

"Y-You disobeyed me..." Mobius muttered to herself as she pushed away from the kiss, swiping away the string of saliva connecting you two. Her entire body was shaking in anger while her eyes flashed with the same frustration and she glared at you. "You were supposed to submit to me and-"

"-to let myself be brought to the brink of climax but be unable to go all the way while helping you. Am I supposed to just be content with how things work out and let you treat me like an obedient pet? Fine, if you want to treat me like an animal," You roughly groped Mobius's ass and lifted her with little to no trouble. "Then, I'll fuck you like one." You growled into her ear and carried her toward the small bedroom she often used whenever she was needed for a multi-day experiment, although, one could argue it would be used for the same purpose today.

Mobius whimpered quietly when she felt you manhandle her and when she realized how quickly you had turned the tables on her. Her arms and legs immediately wrapped around your body, pressing herself against you while she felt your still rock-hard cock teasingly rubbed against her underwear.

The door to her makeshift bedroom was kicked open and the bed inside creaked when you threw her onto her. Without waiting for any orders, Mobius quickly discarded all of her clothes and flung them across the room, leaving herself bare except for her torn pantyhose. She laid on her back and spread her legs wide, rubbing herself while looking up at you with a pleading look.

"So, this is what you were waiting for, huh?" You could tell that Mobius was expecting and waiting for you to take her almost immediately but you decided to hang back, for now, to frustrate her and draw out more from her. "Beg for it."

Mobius's eyes widened but she readily complied. "P-Please fuck my tight pussy..."

"Not good enough. Say it louder this time." You snarled at Mobius who bit her lower lip upon seeing and feeling your harsh gaze. Her mind, hazy with lust, scrambled to come up with a tempting invitation for you to make her lose her mind.

"P-Please take that big, fat cock of yours and breed me until the only thing I can remember tonight is you pumping several loads into me and turning me into your personal cum-!"

Mobius was cut off by you suddenly grabbing her hands and pinning them against the soft mattress. Her eyes rolled up into her head when she felt the tip of your cock push through her tight walls and slam against her womb. Her breath was temporarily knocked out of her from your sheer size and before she recovered, she was swiftly silenced by your lips crashing against hers.

Your hips pistoned back and forth, your cock shoving into and pulling out of Mobius at a speed that she could barely keep up with nor did she want to. All she could understand was that your brutal slams down into her pussy were driving her crazy and stretching her walls far beyond what her previous partners could only dream of doing. The only thing she could do now with you on top of her was to moan loudly into the kiss you two were sharing while squeezing your hands and keeping her legs wrapped around your back as you pounded her into the bedsheets in a rough mating press position.

"This is what you wanted from me, isn't it?" You asked the busty woman after briefly pulling away from the kiss, smiling as you watched her try to cover her face with her hands before she remembered that your hands were keeping them pinned against the creaking bed. Just like with Dr. Mei, her moans sounded more emotional and inhibited in this position, becoming more louder than the sounds of skin slapping and the bed creaking violently.

"Y-Yes..." Mobius moaned and tightened her legs around you. "This is what I wanted for so long! I needed a man that wouldn't let me step all over them like a doormat and would put me in my place whenever I acted bitchy! I-I saw how much Mei was enjoying having sex with you and knew that I needed to have a taste myself!"

"And~?" You leaned down and whispered into her ear while thrusting more quickly into her warm snatch, earning even louder cries of pleasure from Mobius. "What do you think?"

"Best fucking decision of my life!" Mobius moaned with her tongue lolled out lewdly and her eyes struggling to maintain eye contact with you as your cock slamming into her never failed to make her eyes roll upward.

Your hips were working overtime, fueled by the frustration of being denied an orgasm three times now and taking it out on the woman responsible for it in the best way possible. Her walls were hot and tight around your cock, her legs just as constricting around your body, and her entire body submitted to you by laying there for you to ravage without a second thought. The moans spilling from her mouth along with the drool dripping from her tongue, combined with her mind's inability to form a complete, rational thought, shown by her eyes either rolling up or going cross, was more to the burning fire that was your motivation to dick the scientist even harder.

Suddenly, Mobius gasped and her walls clamped down onto your dick without warning, splashing your hips with her fluids. It took all of your willpower to not cum just yet.

"Sneaky little..." You let go of her hands and pulled out, much to her confusion, before flipping her around to where she was on all fours with her luscious backside facing you now. She was expecting to feel you slam back into her sore pussy but instead, her eyes widened when she felt you prodding her other hole.

"W-Wait, you can't! It won't fit-"

A rough slap to her ass made her gasp before a hand pushed her face into the darkened bedsheets, where her sweat had stained it.

"I didn't ask for your permission." 

Mobius shivered when she felt your warm breath tickling her ear, the close proximity of your mouth sending shivers down her back and through her entire body. A mix of pain and pleasure rippled throughout her as she felt every inch fill up her backdoor, and she shoved her face into the nearest pillow, muffling her screams of painful euphoria. However, she wasn't even allowed that small luxury as you grabbed her hair and yanked it roughly, forcing her to remain upright in her position.

With one hand tightly gripping Mobius's green hair, you tore her pantyhose apart to free her pale ass cheeks just so you could give them a couple of smacks each to leave visible handprints while you thrusted into the even tighter hole between them, your balls slapping against her thighs. Her ass was extremely tight and you had to take your time pushing forward - which shouldn't be too much of a surprise considering the impressive size of your cock.

Despite Mobius's initial protest, she was still pushing back to meet your thrusts and moaning with ragged breaths.

"I didn't think you would be into this too."

"As long as that big cock of yours is inside me, I don't care what you do~!" Mobius looked over her shoulder with hearts in her eyes and a lustful expression written all over her face.

"(Man, she's a freak...)" You thought before shrugging and continuing to hammer into her tight ass, pulling her hair every now and then whenever you felt like she was slowing down or whenever you felt like it.

It didn't take too long before you felt the sensation of a long-lost friend and you slammed balls-deep inside of Mobius's now stretched-out ass, emptying your load inside of her. She gasped and thrashed wildly at the surge of white spunk filling her up before her arms gave out.

Pulling out her ass, you took a moment to admire your work: a slumped-over Mobius with her bright red ass in the air and face in the mattress, cum leaking out of her completely gaped asshole.

Yet, your cock remained erect and full of vigor while she was utterly exhausted from the ass-pounding marathon you had put her through.

"Hey, we're not done here." You smacked Mobius's ass and yanked her hair, earning an excited whine from her as she pushed herself back into all-fours. However, you merely tugged her hair again and she turned her body around to find herself staring up at your towering cock, glistening in the light from her juices when you had her in a mating press. "Clean it." You commanded.

"Y-Yes..." Mobius gulped loudly and drooled openly, her mind melting from the scent of your cock hitting her nose. She could see the veins on it, bulging with vitality and her folds began to heat up when she realized that you were far from done with her.

Opening her mouth, she took your tip into her mouth and licked it all over, moaning at the taste, before she bobbed her head. The room, previously filled with the loud noises of the bed creaking, their hips slapping against each other, and her ecstatic cries for more, was now quiet except for the sound of her sucking you off. Mobius's tongue ran over every inch she could take into her mouth while she used a hand to jerk off the rest and the other to massage your balls.

"Good girl..." You groaned and put a hand on her head.

Mobius was conflicted by your words since upon hearing them, her body suddenly threw itself into trying to take more of your cock down her throat. Was she genuinely enjoying this pet calling from you or was her mind so warped by the pleasure that she was accepting all of this? Perhaps, it was a bit of both, she thought. Admittedly, there was a tiny part of her that wanted to make a snide remark but then remembered the state you left her asshole in and decided against it... for now.

There was no time for her to ponder this question further when she felt you place both hands on her head and she realized what you were going to do.

Your hands pushed her all the way down your cock, leaving her wide-eyed and gagging on you. That wasn't all you did, however, as you pulled back before thrusting into her throat, enjoying the muffled moans escaping her mouth with your cock jammed in it. Mobius's saliva and drool covered your cock in its entirety, allowing you to enjoy her warm mouth and tight throat without any hindrances.

"You know, I'm starting to like you better when you're like this: with my cock shoved down your throat." You said while watching Mobius choke on your dick, her eyes either looking up at you or rolling into her head. Maybe even both. Regardless, it looked hot to see her slobbering all over your member when you let go of her head and she went at it.

Mobius pulled all the way back, letting your cock go and taking a deep inhale of air, admiring the sight of it covered in her saliva and drool as well as the lipstick marks she had left on it. 

"Your cock tastes so good~..." She whined, slapping her face with your cock before she dived forward. However, instead of going to town on your cock, she dived down to begin licking all over your balls and leaving kiss marks all over them. Mobius's worship of you didn't stop there and she leaned up to leave marks all over your waist and dick. 

She leaned back to look up at you. 

"My body belongs to you from now on, Y/N~" She said before kissing the tip of your cock as if it were a pledge and that was enough for you to blast her face white, leaving her face, hair, and breasts covered in your cum.

Mobius slowly opened her eyes and looked down at herself to assess the mess that you had made out of her. Without saying another word, she scooped up your cum and licked her hands clean, not wanting any drop to go wasted, and letting out a moan of approval.

"Delicious..." Mobius whispered, looking up when a large shadow covered her face and saw that you were still raring to go.

"Turn around."

With a submissive nod, she hastily turned around and spread her folds apart for you - a waiting invitation for you to spend the night here with her. And, that was not an invitation that you were planning on turning down, she realized when you slammed deep back into her pussy, refilling the room with the sounds of the bed creaking, skin slapping, and, more noticeably, the moans of an unsatisfied woman finally able to find relief for the first time in a long while.

3rd Person POV:

A Few Days Later:

"Lab rat!" The sound of papers being slammed on a desk shook someone out of their stupor.

"H-Huh?" Y/N jolted awake and looked around to find himself sitting in a meeting room with other people he didn't recognize. His memories soon returned to him and he remembered that she was attending a meeting with Mobius.

Speaking of whom, the green-haired scientist was staring him down with an icy stare and he kept his gaze on the table until she grabbed him by his shirt and pulled him towards the door.

"You. You handle the debriefing." Mobius pointed at one of the other people in the room. "I need to have a talk with this creature." She scowled at Y/N and dragged him away, slamming the door behind them.

"Geez, she's been getting angrier towards him lately."

"Yeah, I wonder what happened. Wasn't she being all nice to him before?"

"Poor boy... I can't even imagine the hell she's putting him through..."

The Fire Moth soldiers and scientists collectively agreed except for one person who stood up with a smile.

"Sorry, everyone. But, I should make sure Mobi-chan doesn't do anything mean to little Y/N~" Elysia smiled and waved goodbye to everyone, slipping out into the hallway and making her way through the many corridors of the base.

Eventually, she stopped outside of a closet and entered the secluded room, locking the door behind her. 

"Helloooo~?" With a bright smile, Elysia walked over to the other end of the closet and crouched to get a better look at the scene playing out in front of her: Mobius on her knees and sucking off Y/N.

"Oh, hey Elysia." Y/N greeted her casually, waving at her with one hand while the other pushed the busty scientist to deepthroat him.

"Hi~!" Elysia smiled at Y/N before closely watching Mobius blow him, admiring the way the green-haired woman took him down with little difficulty. "Ah, Mobius. You look so beautiful right now..." She said before pulling out her phone and snapping a photo.

"Mmf!?" Mobius pulled back and was about to demand to know what Elysia was doing but was stopped when Y/N grabbed her and pushed her against the wall. The male quickly pulled down her pantyhose and shoved his cock deep inside of her to take her mind off things.

"Elysia..."

"I know, I know, but you know that I can't help it when I see something beautiful~!"

Y/N merely sighed before turning his attention back to Mobius and began rutting her into a moaning mess.

Elysia took that chance to quietly slip out of the closet and close the door behind her. She leaned back against the steel door and looked down at her phone to see the photo that she had taken of Mobius gazing lovingly at the cock between her lips, unaware of her presence at the time as she was too enthralled in the sloppy blowjob.

However, soon Elysia swiped to the left and looked at the earlier pictures that she had taken with the device. While they were all mostly sweet things like puppies, kittens, or maybe even the latest cakes made at her favorite bakery, the earliest pictures were definitely not anything she would show to both Rin and Griseo.

There was one that she was particularly fond of that she made Y/N take way back then and carried a lot of sentimental value...

Alas, that was a story for another time, Elysia thought to herself and remained planted outside the closet door to prevent anyone from going inside all the while she happily listened to the ecstatic cries of Mobius as she lost herself once more...
