Lisa Loud did not have a particularly active sex life.
Well, to say she had a sex life at all was a bit of a stretch. She was an aloof woman after all, with little interest in relationships, physical or otherwise. This wasn't to say Lisa was a virgin; her first time had been at fifteen, with her then-boyfriend David… a lackluster and passionless experience quite frankly, and the couple had split up not long after.
Her second and last experience, if one could even consider it such, had been with none other than her brother Lincoln. A moment of weakness and desperation on her part, though it wasn't as though there were any real risk: unlike her sisters, years of exposure to radiation and chemicals had left the unfortunate woman barren. Besides, at some level, she wanted to see what all the fuss was about… altered hormones or not, there must have been something about her brother that drew so many women to his bed, right?
Well... no. Or rather, if there was, it was beyond her understanding. He had been effortlessly charming, yes, not to mention quite well-endowed… though Lisa could only assume that too was a result of exposure to her experimental compound. And indeed, even she had found herself far more attracted to him than she knew she should be.
And therein laid the problem. For all Lincoln's charisma, for all his unnatural allure, Lisa saw it for what it truly was: a lie. Nothing more than an illusion caused by pheromones and mutated genes. Her brother was simply going through the motions as if controlled by some sort of primal urge, no different than a lizard flaring its dewlap to attract a mate. That man was simply not her brother, and her guilt at having reduced him to such a state, even unintentionally, led her to put a stop to things almost as soon as they'd started.
After that, Lisa had isolated herself as she poured her efforts into curing her brother's affliction. And even once she'd managed to bring Lincoln back to his normal self, she still remained distant, lest she muck up her siblings' lives even more than she already had. It wasn't until the accidental 'birth' of Lulu that she'd reconnected with her family and, quite frankly, she was glad she had.
While she'd sorted out that aspect of her life, one thing that hadn't changed was her love life, or rather lack thereof. And for the most part, Lisa was fine with that. She was married to her work, so to speak, and had little time for relationships or courtship. And even if she did, she simply didn't have the necessary social skills to make it happen… besides, while far from unattractive she was a very plain-looking woman, especially compared to the rest of her sisters. She had little to offer any potential suitors, and likewise they had little to offer her. Still, Lisa was only human, and as such had needs just like anyone else. She would touch herself when the urge arose, sometimes to nothing more than her own thoughts, and sometimes to pornographic material.
Purely for research purposes, of course.
Perhaps it was this curiosity that led her to intrude on her nephews' private business. While once she had been more than willing to invade her family's privacy, the years had brought with them a measure of restraint and decency she'd once lacked. But once it became clear that her nephews were already sexually active at such a young age, she couldn't help but look into the matter herself.
Needless to say, her findings had been… surprising.
While she'd managed to cure the compound's effects on her brother, it seemed his sons had been born with their DNA permanently mutated. All three were disproportionately well-endowed for their age, with an unusually high sex drive to match.
Fortunately, the effects seemed to stop there: all three boys were very much still themselves, and even when engaged in sexual activities they seemed just as invested in their partners' pleasure as their own. And, if said partners' reactions were anything to go by, they seemed to do quite a good job of it. However, the matter was still something of a concern to Lisa. While they were stable now, there was no telling what long-term effects might arise. It was important that she conduct further research to rule anything out. And that led to the current situation. Further research meant she would need to collect data and samples from one of her nephews directly. And, after some thought, she'd settled on the youngest of the three: Bobby.
There were several reasons for this… for one, as the youngest of the three he had only started going through puberty within the last year or so, making him the best choice to observe the ongoing changes to his DNA. Secondly, unlike Lemy and Lyle he was only half Loud, which Lisa theorized would make these changes far more apparent. Lastly, she'd grown quite fond of Bobby as of late. Lulu's quick attachment to him had caught Lisa's interest and she'd made an effort to get to know him better, finding him to be a highly intelligent and inquisitive boy who always seemed interested in what she was working on, even if he didn't fully understand it. Though she hated to pick favorites she couldn't deny that she was closer to him than the others, and hoped that this would make the boy more cooperative.
Now, the child in question nervously sat on the examination table in naught but his boxers. He wrung his hands in his lap, keeping his head downturned and blushing beet-red from his face down to the tips of his toes. Barring some mild protests Lisa had taken hair, skin, and blood samples without much issue… but there was still one more to go.
"Robert, there's no need to be so nervous." Lisa rolled her chair over to the examination table, setting an empty petri dish beside Bobby before sitting down with her clipboard in hand. "I'm not the first person to see you without clothing."
"I-I know…" Bobby stammered, fidgeting in place awkwardly. "I-it's just… I don't… I-I-I can't… do it with someone watching…"
"It's crucial that I observe the process firsthand, Robert," The scientist said in a calm, gentle tone. "As I explained, your biology is-"
"Different… I know…" The chubby boy said with a sigh. "B-but… why the cameras, then…?" Lisa averted her eyes and pushed up her glasses.
"...It's important to document these things, Robert." She muttered, clearing her throat before continuing. "Now then, if you would be so kind as to remove your undergarments, we can begin." Bobby mumbled something indecipherable, giving a small nod.
"Um… c-can you… look away, then?" He asked.
"I… don't see how that will make a difference, but very well." Lisa swiveled away from him, hearing the gentle rustling of fabric from behind her. "I'll still need to observe the act itself, however."
"...I know…" The boy said quietly. "U-um… okay. Y-you can look…" Lisa turned back around to find her nephew sitting nude and covering himself with his hands. The woman cleared her throat again.
"Robert. Your hands, please."
"R-r-right…" Bobby hesitated a moment before removing his hands from his lap and uncovering his…
...Rather ordinary-looking penis, if larger than one would expect for such a young boy.
"Er…" Lisa's eyes narrowed and she leaned forward, adjusting her glasses as she took a closer look. "...I'm sorry, Robert, but is it too cold in here for you…?"
"N-n-no…" The boy said, his voice coming out as a raspy squeak. "Um… L-Lemy says we're 'growers, n-not show-ers'..."
"Ah, yes. I see." The scientist said with a nod of understanding. It made sense… surely, such a large organ would be an inconvenience to one's daily life otherwise. She drew a small plastic bottle filled with a clear substance from her coat and handed it to Bobby, then leaned back and crossed one leg over the other, readying her clipboard. "Very well. You may proceed."
"Y-yeah, I, um… yeah…" Bobby swallowed and squirted some of the lubricant into his palm. He gently grasped his flaccid member with a trembling hand, slowly beginning to work it up and down along the shaft. He kept his eyes squeezed shut, doing his best to pretend that his aunt wasn't watching him, but to no avail… he could practically feel her gaze on him, and the sterile environment did little to steady his nerves. Lisa watched intently for well over a minute, frowning at the lack of apparent change; finally, the boy sighed and shook his head. "I, um… I-I can't. S-s-sorry…"
"I see… perhaps I should have known better than to assume you could 'perform' without some means of external stimuli. One moment, please." Lisa rolled back her left sleeve, revealing what appeared to be some sort of watch or smart device; she pressed a button on the side and, a moment later, what appeared to be a holographic screen and keyboard formed midair. "Now then… Robert, do you have any preferences as far as sexual fetishes?"
"I… huh…?"
"Amateur? Anal? Bondage, perhaps?" She rattled off kinks as she scrolled through the available offerings, her nephew's blush growing by the second. "Given your romantic inclinations, perhaps interra-"
"I-I-I don't look at that kind of stuff!" Bobby sputtered. His aunt cocked an eyebrow.
"No? Very well… perhaps this would suffice," Lisa said. She 'tapped' a few keys on her nonexistent keyboard, then, with a swipe of her hand the holographic screen floated in front of Bobby. To his horror, he was met with a video of his first time having sex with Gwen… several videos in fact, displaying the act in multiple angles with crystal-clear audio. Bobby let out a stream of flustered gibberish and desperately flailed at the screen, as though he could somehow dissipate the image before him.
"TURN IT OFF! TURN IT OFF!" The young boy sputtered. Lisa frowned but nonetheless complied, ending the playback and powering down the device. The woman sighed and leaned back in her chair, massaging her temples. She'd expected her nephew to be somewhat reluctant about the situation, but she'd never had thought he would make things this difficult.
"Robert, please. I'm trying to make this as easy for you as-"
"E-EASY for me?! Th-that was… why do you have that?! How did you get that?!" Bobby still looked somewhat frantic; he was breathing heavily and his eyes were practically bulging out of their sockets.
"As I said, Robert," She began calmly, "Thorough documentation is important. Besides… it seems to have worked as intended." Lisa looked down at the boy's engorged member with a small smirk; he let out a small yelp and covered himself with his hands again, not that it did much good. She cleared her throat and Bobby swallowed, giving a small nod of his head and reluctantly withdrawing his hands.
The scientist leaned forward, adjusting her glasses so she could take a closer look. She'd known he was big for his age, but seeing it up close like this was jarring nonetheless. It was shorter than either of his brothers', but midway down the shaft it widened out before tapering off again near the base. Even without a direct comparison, Lisa was almost certain that at its widest point it was even thicker than Lemy's.
"Interesting…" She muttered. It was an unusual shape, to be sure… she couldn't help but be reminded of a canine's knot, and could only imagine that it served a similar function during copulation. By chance, of course; Lisa doubted that the compound's effects would be so precise as to specifically reshape his anatomy to facilitate reproduction.
Probably.
"A-aunt Lisa…? What're-" Bobby gasped as his aunt gingerly took hold of his cock. She examined the appendage with notable interest, gently turning and manipulating it in her gloved hand. The young boy squeezed his eyes shut and bit his lip, shuddering at Lisa's touch… something the woman was able to pick up on.
"Robert… is it more pleasurable for you if another does it?" She asked; Bobby hesitated a moment, then gave a small nod. "...I see. Very well, then." Lisa released him and slid off her glove, setting it aside before taking hold of her nephew's member again, eliciting another gasp.
"W-wait… y-y-you don't have to-"
"It's fine. If this facilitates the process, I have no qualms in helping you along." Bobby was about to protest, only for his voice to crack as she began slowing pumping her hand up and down his length. Her hand was surprisingly soft, and thanks to the lubricant slid along his member with little effort. "Is this alright?"
"...Huh…?" Bobby opened his eyes to find his aunt looking at him with a questioning gaze. "Um… y-yeah… it's… nice," He assured her. She was somewhat clumsy in her technique, yes… but it still felt good.
"Good." Lisa gave a satisfied nod and continued working the young boy's shaft. "I only ask tgat you give me a warning before you ejaculate."
"Um… I-I'll try…" Bobby stammered between breaths. He'd never been particularly good at giving warning; his climax always hit hard and sudden, which had resulted in an unfortunate partner receiving an eyeful of spunk on more than one occasion. Glasses or not, he'd rather spare his aunt the same fate, especially considering how closely she was observing the appendage. Lisa, however, was not quite as stoic as she appeared. It had been a very long time since she'd seen a phallus in person, let alone one so large… altered genetic structure or not, for a boy his age to be so well-endowed seemed almost ridiculous. She could feel it throbbing in her hand, and her cheeks grew hot as Bobby's pleasured moans and whimpers filled her ears.
The scientist couldn't help but bite her lower lip slightly as a bead of pre-cum formed at the tip, feeling a tingling in her nethers that she hadn't felt in quite some time. Usually she was able to keep her more primal urges at bay, on the rare occasions she felt them at all. But there was something about her nephew that was stirring her arousal; perhaps it was the blissful sounds escaping his throat, or the way he bashfully covered his reddened face with his hands, or how his girthy member both intimidated and excited the petite woman.
"Um… a-aunt Lisa...?"
"Hm?" Lisa snapped out of her daze to find her nephew staring at her, seemingly surprised and flustered by something. She followed his gaze down to find, to her shock, that she had reflexively slid her other hand between her legs. Even through the fabric of her pants she could feel the heat radiating from her crotch. She withdrew her hand with a gasp, her cheeks turning a light pink. "O-oh… er…" The woman averted her eyes and coughed into her fist. "...Just... scratching an itch."
"Oh, right…" Bobby mumbled sheepishly. Lisa sighed and paused a moment to push up her glasses. She mentally kicked herself for losing her composure… she was supposed to be above such things. She assumed she was simply too pent-up for her own good. It had been quite some time since she'd last pleasured herself after all, so perhaps she shouldn't have been surprised that such an exceptional bit of anatomy would rile her up a bit. But no matter; she'd simply finish up the task at hand and 'take care' of herself once the boy had gone home.
Or…
Lisa furrowed her brow as she looked down at the engorged member in her hand, weighing her options. She knew that she should simply finish the job, collect the sample, and be done with it. Why, the mere fact that her young nephew was having such an effect on her filled her with a deep sense of shame and guilt. He was just a child, after all.
But on the other hand, what would the harm be? This wasn't the same as the situation with Lincoln years prior… Bobby still had his wits about him, he was already sexually active, and it wasn't as though she could get pregnant. Besides, what better way could there be to gauge the effects of the boy's mutations than to experience them firsthand?
...For science, of course.
"...Robert…" Lisa said as she withdrew her hand from Bobby's shaft, to his visible disappointment. "I have… something of a proposition for you." Bobby frowned and tilted his head slightly.
"A proposition…?" Bobby muttered. His aunt gave a small nod.
"Given your sexual experience, I suppose this might not be enough to properly satisfy you," The scientist explained. "Would you… that is…" Lisa trailed off, her cheeks reddening slightly. Bobby couldn't help but notice the shift in his aunt's demeanor. "...Would you prefer we take the direct approach?"
"Direct approach?" Bobby asked, cocking an eyebrow in confusion. Lisa sighed as she lowered her glasses and rubbed the bridge of her nose.
"I'm asking if you wish to partake in sexual intercourse with me, Robert," She said in a quiet, almost hesitant tone. The boy blinked, and for a few moments said nothing as his brain processed his aunt's offer. Soon, his eyes slowly widened as his cheeks turned a deep shade of red.
"U-um… w-with you…?" Bobby mumbled. He averted his eyes from his aunt and anxiously wrung his hands in his lap.
"It's alright if you say no," Lisa clarified. "I… I simply feel it would be beneficial for my research."
"I-I see…" Bobby muttered. He was somewhat surprised Lisa was giving him a choice at all… though he supposed even she knew when to draw the line. Still, he was torn: on the one hand, despite his earlier reservations the boy was hard as a rock and eager to finish… and quite frankly, he'd prefer sex to a handjob any day. But on the other hand, he wasn't all too keen on doing for the sake of research. Sure, he enjoyed sex as much as anyone, but he prefered for it to mean something.
Bobby looked up from his lap to meet his aunt's eyes, only to find her looking away at nothing in particular. He loved Lisa, to be sure… she was his aunt after all, and beyond that he'd grown to feel a unique sense of kinship with the fellow social outcast. That said, he'd never found himself attracted to her like he was to some of his other aunts. It wasn't that she was unattractive per se; he'd just never really thought about her that way, nor had he ever felt any sort of indication that she may be interested in him. But the way she kept her gaze trained away from him, red-faced and drumming her fingers against her knee anxiously…
He had to admit, it was kind of cute.
"U-um… are you…" The flustered boy stammered, pausing to wet his lips. "A-are you sure that's okay…?"
"I assure you, I am quite sterile," The woman stated plainly. "There is no risk of pregnancy."
"No, I mean… are you sure you're okay with it?" He asked in a sincere tone. "Doing… y-y'know… with me?" Lisa raised her eyebrows in surprise, then shook her head and chuckled.
"You're a good boy, Robert." She said. "But you need not worry. I wouldn't have offered if I were unsure." Lisa gently patted her nephew's head, earning her a small smile from the boy. His concern set her somewhat at ease... of course, his kind-hearted nature was in part what drew her to him in the first place. Bobby looked away again, biting his lip in thought, and then gave a small nod.
"...O-okay, then." He said softly. With that, Lisa got to her feet and, to his confusion, began walking to her desk. "Where're you-"
"I hope you don't mind if I take notes on the experience," Lisa said as she removed her lab coat, folding it and setting it down on the desk. "Come, Robert. No sense in waiting, seeing as how I appear to have… left you hanging, so to speak."
Bobby cocked an eyebrow but nonetheless complied, hopping down from the exam table and joining his aunt by her desk. The young woman glanced down at him, finding the boy's cock staring back at her, swollen and raring to go. Lisa swallowed, shutting her eyes and taking a deep breath. Too late for second thoughts. She exhaled and, after a moment's hesitation, began to unbuckle her belt. To her amusement Bobby sheepishly turned away as she lowered her pants, followed by her plain white panties; as though he weren't about to see everything regardless. Still, if nothing else, his antics at least helped to take some of the edge off.
"Right, then…" The scientist stammered, clearing her throat. "...I suppose… I'll leave the matter to you, then." Bobby gave a nervous nod and Lisa bent over the desk, using her folded lab coat as a sort of cushion for her elbows. As she took up her pen and clipboard Bobby finally ventured a look, turning beet red as he found himself staring at his aunt's bare rear end. Even at twenty-nine years of age, Lisa was a petite woman… slight of frame and short in stature, it was almost as though she simply stopped aging in her late teens. Whether this was due to radiation exposure or simple genetics, Bobby couldn't say, nor did he see fit to ask. In any case, it came as little surprise that the rest of her was similarly youthful in appearance; beneath her smooth cheeks was a clean, hairless mound and surprisingly small slit. She may not have had the most stunning figure, but Bobby certainly couldn't deny it was an enticing sight. "Robert?" Lisa asked, snapping the boy to his senses. "...Whenever you're ready."
"R-right, um…" Bobby took a shaky step forward, before something dawned on him. "I, uh… I-I can't reach," He said bashfully.
"...Oh." An awkward silence fell between the two, and after a few moments Lisa cleared her throat. "There's… there's a step-stool under the desk," She said quietly. "It should be tall enough for our purposes."
"O-okay." As Bobby retrieved the stool, Lisa sighed and massaged her temples. The fact that he needed a step-stool just to reach her brought the reality of the situation back in full force: she was about to have sex with a child. Her own nephew, no less. Lisa had done many questionable things over the course of her research, but this was extreme even by her standards.
It's fine, Lisa told herself. This is for science, after all. Bobby set down the stool behind her and stepped up, placing his hands on the woman's hips to steady himself. Lisa jumped slightly at his touch, to her chagrin. She was on edge again... She needed to compose herself.
"Okay, uh… are you ready…?" Bobby asked. Lisa hesitated a moment, then gave a nod.
"...Yes. You may begin." She shut her eyes, bracing herself for what was to come. Her nephew's cock stood at full mast as he got himself into position, taking one hand from his aunt's hips to guide it to her wet slit. She jumped again, taking a deep intake of air as his head pressed against her entrance. Come on, Lisa… you're being ridiculous, she thought. She exhaled and steeled herself for what was to come, bringing her pen to her clipboard in preparation of taking notes. But as Bobby's cock pierced her folds she yelped in surprise and instinctively jerked away from the intrusion.
Bobby's brow furrowed in confusion. He may not have had the most expansive set of partners, but he'd been with enough older women to know that this was somewhat unusual. Her reactions, her tightness, the resistance he'd felt as he pushed in… it reminded him more of Gwen or Reina than a grown woman, especially in their family.
Wait…
"Um… aunt Lisa…" Bobby frowned and leaned to the side just enough to see her face. "H-have you… never done this before…?"
"I… o-of course I have…!" Lisa sputtered, her cheeks turning a deep red in indignation. "Just… i-it's been quite some time, that's all…"
"Should we stop?"
"...No," Lisa said with a sigh. "No, I'll be fine. Just… go slow, if you would."
"O-okay," Bobby muttered. He was a bit surprised that his aunt was so inexperienced, but he supposed it made sense… like himself, she'd always had difficulty connecting with others, and as far as he knew aside from their family and Darcy she didn't have much of a social life to speak of. Even Bobby himself never actively sought out sex, it just seemed to happen to him.
Case in point.
Still, this changed things. If Lisa was this jumpy, Bobby doubted that having sex would be an easy task for her… and research purposes or not, he wanted to be sure she felt good too.
"Robert? Are you-" The woman let out a sharp gasp as something hot and wet slid along her entrance before dipping into her, gently probing and exploring her warm folds. She looked over her shoulder to find her nephew with his face buried in her rear, eagerly lapping at her womanhood. "R-Robert, there's n-no need for… ah…!" Lisa let out a moan as Bobby's tongue flicked across her clit. She tried to speak again, only for her voice to die in her throat as another flick of the boy's tongue nearly made her legs buckle. She hadn't expected foreplay to factor into this little 'experiment', but perhaps it was best to simply leave the boy to his work… besides, she couldn't deny it felt very good. "V-very well…" She muttered under her breath, turning her focus to the clipboard and unsteadily writing down notes on the experience. 'Subject shows an impressive degree of oral dexterity,' she wrote, 'indicating substantial experience in the act of cunnilingus, if not-' Lisa gasped again as a roll of Bobby's tongue sent another shiver of delight through her body. '-a natural talent for it. Nature of the act suggests a desire to please his partner as well as himself.'
Bobby licked up a few beads of Lisa's juices as they dripped down her thigh, then wiped his mouth with the back of his hand and got into position. As much as he enjoyed his aunt's taste, he figured that it would be best to move things along now; judging by the way she was fidgeting in anticipation, it seemed that she was more than ready for him now. Lisa shuddered and tensed up as she felt Bobby's cock pressing against her awaiting slit. She took another deep breath and braced herself as he slowly pushed in, her moist walls parting to grant him entrance. Though her body was now far more willing to accept his, her lack of experience and the sheer girth of her nephew's manhood meant that there was still some resistance, especially as it neared the thickest point. Lisa winced and clenched her teeth as her tight walls stretched to accommodate him, finally letting out a gasp of pain as the bulge slipped in.
"A-are you okay?!" Bobby asked, halting his efforts out of concern for his aunt.
"...Yes… y-yes, I'm fine," She assured him. "Just… startled, more than anything." Bobby frowned, but nonetheless nodded in understanding. It wasn't a complete lie… what small amount of pain she did feel faded quickly, replaced by a sense of fullness as her nephew bottomed out within her. She took a moment to jot down her notes on the penetration. "You may proceed when you wish."
"O-okay, then." The boy said quietly. "Just let me know if it's too much." Gently gripping his aunt's waist, he began to slowly move his hips, shutting his eyes and letting out a soft moan at her tightness. Lisa bit her lip, squeezing her pen tightly as she continued writing.
'Initial discomfort passed within a few moments,' The scientist wrote in a shaky hand. 'Subject started slow; whether for his benefit or mine, I do not know. In any case, the pleasure is s-' Lisa's hand jerked, leaving a long line across the page as Bobby pulled out nearly entirely before quickly pushing back in. Lisa had to stifle a cry of pleasure as she felt the head of her nephew's cock hit her cervix, before the boy returned to a moderate pace. '-significant,' Lisa wrote, 'and, despite my prior observations, unexpected.'
Bobby was panting, the step-stool wobbling slightly beneath his feet as he thrusted into his aunt. Thankfully, her short stature made this easier than it would be otherwise. Her walls were gripping his shaft tightly, and he could see her shuddering each time he pushed into her. It was clear to him that she was enjoying this far more than she was trying to let on. More so than his endowment, it was his adaptability that made him such a good lover… his ability to pick up on his partner's needs and adjust his approach accordingly. He took notice of each subtle movement, each gasp, each stifled whimper as he plowed her.
"A-ah…" Lisa let out a shuddering breath as her nephew picked up the pace. Her body was gradually becoming accustomed to his cock, her muscles loosening up and allowing him to pound her freely. She furrowed her brow and tried to keep her wits about her. 'Subject has increased efforts expnentialy. Sensaton can only b dsscrib as inttens and-' As the boy's cock bumped against her cervix again, the pen slipped from her sweaty hand and rolled across the table. Not that it mattered… Lisa's handwriting had grown so sloppy and erratic that it was quite literally unreadable, and she could barely even see what she was doing through her fogged-up glasses anyway. Lisa lowered her head, giving up on the notes entirely. She hadn't been ready for this. It was nothing like her first experience with David, nor her uncomfortable attempt with Lincoln… she'd never felt anything quite like this, and any semblance of composure she had left was quickly pushed aside. She glanced over her shoulder, her hazy eyes briefly meeting those of her nephew. She wanted more, and the small smirk that crossed his flushed face told her he got the message.
Bobby was moving faster now, his hips slapping against her ass with each thrust. Her notes, already stained with droplets of sweat, were crumpled into a ball as she reflexively clenched her fist. Lisa didn't care. Nor did she care that her glasses lay askew, or that there was a bead of drool trickling down her chin, or that her immodest moans were echoing throughout the lab. At that moment, all she cared about was the thick cock slamming into her womanhood. She'd ceased her passive involvement and had begun fucking him back, moving her own hips to meet his with each thrust and gasping each time he struck her womb. She could feel herself nearing the edge, and her nephew's increasingly ragged breaths told her that he was almost there as well. And then, the boy reached under her and began to rub the woman's sensitive clit. Lisa cried out in shock and pleasure, her walls clamping down around Bobby's cock.
"A-aunt Lisa…!" Bobby whined as her pussy tightened around him, begging for his cum… and he was all too happy to oblige. He bucked his hips and hilted within her, and Lisa's eyes going wide as his cock swelled inside of her. She felt a sudden warmth as a blast of cum hit the back of her womb, sending the woman over the edge. She arched her back, crying out in ecstasy at the most intense orgasm of her life; she could feel rope after rope of her nephew's hot seed pumping into her, her abdomen swelling slightly as the boy's throbbing member prevented any cum from escaping.
Bobby stood on shaky legs, his hips spasming as his aunt's walls squeezed and wrung him out, coaxing out every drop of cum they could. With a feeble moan Lisa's legs gave out, and without his aunt's waist to support him the boy felt the step-stool wobbling beneath his feet; he let out a yelp as he fell back, his cock slipping free with a soft 'pop' as he fell flat on his rear end.
"...I'm okay…" Bobby grunted, wincing and rubbing his sore bottom. But Lisa didn't appear to notice; the woman was slumped over her desk in exhaustion, panting heavily as a torrent of her nephew's cum poured from her well-fucked cunt. Bobby frowned in concern, unsteadily getting to his feet. "A-are you alright…?" For a few moments, Lisa didn't respond… she was in a daze, still coming down from an orgasm so powerful she was practically dead to the world. "...A-aunt-"
"Yes… I-I'm… I'm fine." Lisa managed to murmur to her nephew's relief. She re-adjusted her glasses and then slowly, unsteadily, she managed to find her footing and turned towards Bobby, bracing herself against the desk as she looked down at the steady flow of cum in awe. There was so much that she could still feel its warmth deep inside, and once she got her wits about her she snatched a vial off the desk and filled it with the viscous discharge.
"Um… s-sorry." Bobby mumbled sheepishly. "I-I probably overdid it a bit…" Lisa cocked an eyebrow, then shook her head and chuckled.
"Not at all. You did… well." The woman said, averting her eyes and scratching her reddened cheek. "Remarkably so, in fact…" She muttered under her breath. Bobby tilted his head in confusion.
"What was that?"
"...Nothing," Lisa said, clearing her throat before smirking at the boy. "In any case, it would seem I've obtained the required sample. Thank you for your cooperation, Robert. It was… very enlightening." The young boy smiled and looked away, bashfully kicking at the floor.
"O-oh, uh… i-it was no problem…" He said with a grin. Lisa raised the vial to take a closer look at the opaque substance within. Though it wasn't quite 'sterile' anymore, she supposed it would be fine for her purposes… besides, she certainly had plenty of it to work with. Bobby watched as his aunt staggered off towards a rectangular unit similar to a filing cabinet, leaving a trail of cum behind her. "Um… aunt Lisa…? Y-you're making a mess…"
"It's quite alright," Lisa assured him. "I have automated sterilization procedures in place… they should activate within a few moments." She typed something on a keypad on one of the 'drawers' and opened it only for a haze of fog to escape from within; Bobby could only assume it was some sort of freezer unit. Lisa shut the drawer and entered the code again to lock it. "There… now then," She said, turning to face her nephew. "I suppose that's that."
"Yeah…" There was a heavy silence between the two, now that the moment had passed… somewhere over the course of their coitus, Lisa had all but forgotten that the boy ravishing her was her own nephew… a child. Granted, he certainly hadn't felt like such. But the boy seemed no worse for wear, and in fact seemed to be recovering quite easily compared to herself. She supposed that boiled down to the sheer gap in sexual experience between them. "Aunt Lisa…?" It was Bobby that broke the silence; the still-naked little boy shuffled up to her, twiddling his thumbs and chewing his lip anxiously. Lisa frowned.
"Yes, Robert?" The boy furrowed his brow, wringing his hands and looking up at his aunt with an uncertain gaze.
"Um… did you… did you like it…?" He asked. Lisa raised her eyebrows in surprise.
"I…" Lisa coughed, her cheeks reddening as she adjusted her glasses. "I, er… that is…" She stammered, before letting out a sigh. "...I did." She admitted, a flustered smirk crossing her face. Her nephew lowered his face and gave a small nod, mumbling something that sounded like 'me, too'.
There was another awkward pause, broken only by the mechanical revving of an automated cleaner-bot as it got to work wiping up their mess. Lisa pursed her lips and studied the boy before her: though sweaty and a bit worn from his efforts, he otherwise seemed just fine. And as her eyes wandered lower, she noticed he was still semi-erect. The scientist quickly averted her eyes, biting her lip as she once again felt that tingling down below. For crying out loud, they had just finished… and surely the boy needed his rest, right? Though, thinking about what she'd observed in the past, it dawned on her that the boy often lasted multiple rounds… it wasn't rare for he and his partners to go again after a short rest, even up to three times on at least one occasion. And, seeing as how her notes on the experience had been ruined… well, the day was young, and she had little doubt that her nephew would be willing to endure some further experimentation before returning home.
In her private quarters, this time.
...For research purposes, of course.
