Mom's Perspective: The Experiment
Everything was going according to plan until the State went into lockdown. The laboratory had to be temporarily closed and the research team was ordered to work from home.
The experimental drug made Elizabeth's breasts swollen and filled with milk, since they were now deprived of the industrial strength pumps in the laboratory.
She milked herself twice a day in her bedroom, having been supplied with breast pumps, small sealable bags, and a cooling container for transport. Each sample of her milk was invaluable as they represented gradual changes in her body. Her basement freezer was full of bags which had been carefully marked with the date.
There was just one problem; her milk supply seemed to be associated with heightened sexual activity. Technicians in the labs typically helped her navigate that snafu. Now that she was isolated, it was more of a challenge.
Left without a proper outlet, Elizabeth's hormones were teetering on the brink. She was in constant communication with the team who devised a highly personalized masturbation routine for her. But eventually, even that wasn't enough.
A new plan was created for Elizabeth, which shocked her to the core. At first, she refused to comply with the outrageous regimen. Any mother would. But hormones of this magnitude cannot be ignored forever.
The lead researcher wrote, "You have two, well-educated helpers at home. My professional recommendation is that you train them to provide quality assistance. Remember, this situation is temporary."
Of course, that message was in reference to her adult offspring, who were staying at home with her during the quarantine. Correspondence with the lead researcher had gone on for nearly a week before Elizabeth's estrogen had completely taken over her decision making abilities.
Getting naked in her bedroom, she put on a silk robe, then walked barefoot down the stairs and towards the living room. She had already texted Abby and Ray to meet her there, where they would soon receive the shock of their lives.
Her daughter Abby, a recent college graduate, had already been accepted to dental school. Like mom, Abby was a science-minded woman who wanted a career helping people. And what better way to help people than with this sort of research?
Her son Ray, on the other hand, was still a college student finishing this semester online at home. Like most college guys, he enjoyed sports, video games, and hanging out with friends. Surely he'd be up for an idea like this, because what young man could ever turn down a glorious pair of milk ripened breasts?
Elizabeth struggled with her decision as she approached the living room and saw her beloved adult children. They were a study in contrasts... so adult, yet innocent in many ways.
Her son turned off the television as she entered and both siblings seemed thoroughly amused that she was wearing such a sexy silk robe. It was more appropriate to wear in front of lovers, not offspring. Having always been a traditional mother, she preferred looking respectable at all times.
Nudging between them, Elizabeth sat in the middle of the couch. Leading with small talk, she tried to put them at ease. They joked about her robe and she said there was a perfectly reasonable explanation.
"I should have been open about this from the start," Elizabeth confessed. "But the truth is, I tried to keep it a secret. It's a little embarrassing, and frankly, it's also very personal."
Abby looked upset. "Is something wrong?"
"Is everything okay, mom?" Ray asked, equally worried.
Elizabeth smiled lovingly. "I'm fine. In fact, I'm more than fine. I've volunteered as a test subject for a medical experiment and the results have been spectacular."
The looks on their faces changed and Elizabeth knew she had their full attention. Both of them were smart and captivated by the idea that their mother was involved with a scientific breakthrough.
She continued, "Finances have been tight lately. So when my employer offered $30,000 to join this study, I jumped at the chance, even though my work is focused on a completely different specialty. The team leader is a brilliant physician whom I greatly respect. It's been incredibly convenient that we all work in the same building... well... until the lockdown happened."
Ray nodded in appreciation, "Nice, that's some serious money."
"What kind of experiment?" Abby asked, wide-eyed.
Elizabeth was about to answer, but decided to respond by untying her silk robe and opening it completely. She pulled her arms from the sleeves, exposing her voluptuous, firm breasts to Abby and Ray. Even without looking, she knew the siblings were captivated by her enormous tits. And she was equally certain her big brown nipples had become fully erect. These days, her nipples hardened at even the slightest provocation.
"I'm lactating again," Elizabeth said, in a matter-of-fact way. "I take pills in the morning and night. Thanks to modern science, I feel ten years younger and my body is functioning like it did in my early twenties."
She managed to find the courage to look directly at her adult children. Abby was in awe; Elizabeth instinctively knew it was the academic aspect that captivated her oldest child.
Ray didn't know how to process the information he had just been given. Elizabeth wasn't even sure he heard what had been said because he appeared completely engrossed with the magnificent set of tits well within his reach.
"Are they painful?" Abby inquired, thinking clinically.
Ray, looking as if he might drool, asked, "Is there a reason you're showing us?"
"There's talk of the lab reopening in two weeks, but that feels like an eternity. You see, before the shutdown, I had been getting my breasts drained by special milking machines. Without access to the lab, I'm ready to explode."
"In what way?" Abby questioned.
Elizabeth took a steadying breath. "My hormones are raging and I can't relieve myself properly. Having to drain my breasts every day is exhausting. And my libido has never been this powerful."
She saw looks of disbelief on their faces, which strangely heightened her arousal, causing her nipples to harden even further.
"You mean..." Ray's voice trailed off.
Elizabeth cupped her round globes with petite hands. "If you're interested -- and believe me, I'm not trying to twist your arms -- both of you can help me. Think of this as a job. The lab has already agreed to pay each of you $5,000 for services rendered. They'll also count this as job experience, so you can both put 'research assistants' on your resumes. What do you think?"
"What will we have to do?" Abby asked, predictably interested in the scientific process.
"I think it's obvious," Elizabeth said, feeling her pussy burn.
Not wanting to speak further, she kept rubbing the undersides of her swollen breasts as the siblings watched the salacious show. They were both mesmerized by the sight. At this point, her aching tits were swollen and small droplets of milk appeared at the tips of her nipples.
Past the point of no return, there was nothing she could do to stop rivulets of milk as they began to trickle down her fleshy orbs. Heavy with sustenance, they were ripe and ready for relief.
Elizabeth closed her eyes and prayed that neither of her adult children would walk out in disgust. However, if they did, she'd understand. This situation was bizarre by any standard. Asking them for this kind of help was engaging in a taboo that was several millennia old. She knew her status as a mother would never be the same, but she had been left with no choice.
Suddenly, Elizabeth felt a warm and wet sensation on her right nipple. It was her daughter Abby who had gone first, which wasn't a surprise. Her daughter's strong sense of empathy and caring nature made her the obvious choice. Looking down, she saw Abby cautiously lick her leaking nipple.
Then licking became sucking, and soon, Elizabeth found herself being nursed by her own daughter. This was something she never could have foreseen only a few weeks ago.
When Ray latched onto her left nipple, Elizabeth was officially nursing both siblings at the same time. Her clever son used the back of his throat to produce a very powerful sucking force. If he continued, her breast would be drained quickly.
Elizabeth knew that her son was eager to outperform his sister and being decisive was Ray's forte. She tried not to moan when Ray continued to deplete her breast milk, with what appeared to be innate talent. His success certainly caught the attention of Abby, who had her eyes fixed on him.
Though Abby's initial attempt was mediocre, she was a quick study. Having observed Ray in his element, she seemed to catch on and mimicked his strategy.
Elizabeth watched Abby get down on her knees, just like her brother. Both siblings nursed on her tits, side by side. They had always been competitive and Elizabeth was thoroughly amused.
As expected, her daughter had a newfound confidence, copying the technique of her son. Now both of their mouths were fully latched onto her hard nipples. Elizabeth's eyes rolled back as milk shot from her breasts. Instead of plastic containers collecting her nutritious fluid, she was glad to share it with Abby and Ray, who took on the task with vigor.
Over the years, she had raised them to work as a cohesive unit. For her, family always came first and they were instilled with that sentiment early on in their lives. There was nothing she wouldn't do for them and knowing they felt the same was more than rewarding, it was life affirming.
Working up courage she didn't know existed, Elizabeth moved both hands to cradle the back of their heads. That made the connection complete. She comforted them as they provided her with a vitally important service.
What was more difficult to reconcile was the imminent explosion building between her legs. Because this new drug had a profound impact on all her female hormones, it was common for her to orgasm in front of the research team which included physicians, both men and women. Though she was initially mortified by the idea that strangers watched her dramatic sexual climaxes, it had become routine.
The magnitude of her orgasms had been shocking when she began the trial. Though fairly conservative, she enjoyed a healthy sex life when in relationships. The climaxes she experienced from the drug made all previous sexual encounters seem like small flickers, compared to a raging wildfire.
She grew increasingly conflicted, wondering if she should speak up and ask the siblings to stop, or try to weather the growing storm of a potential orgasm. Unable to control her own body, her hips squirmed.
Amazingly, she was able to keep the top half of her body immobile. Perhaps this method could work, she reasoned. Ray and Abby need never know the extent of her sexual desire.
She was both proud and mortified when Ray detached from her breast and peered into her face, seeming far more in tune with her current need than Abby. Looking at her with an inquisitive expression on his face, it seemed like Ray was about to speak, but reconsidered. Was he going to say something about her need for an orgasm, but shied away? Ray was a very good son.
For over fifteen minutes, they fed on their mother's breast milk. By her estimate and experience, several ounces had been drained from each tit. Just before finishing, Elizabeth found her secret moment of completion as she orgasmed from her movements on the couch.
Biting her lower lip, she managed to avoid making a fool of herself with a big orgasm, like she did in the lab. If either sibling had noticed her tremors, they kept that observation quiet. Ray and Abby finished at the same time and withdrew from Elizabeth's nurturing grasp as they let go of her nipples.
No words were exchanged between the mother and her adult children. This was strictly a family matter and the trio appeared to be in perfect sync with each other. Maternal pride prompted Elizabeth to look from one sibling to the other and as she saw a small trickle of milk on the side of Abby's mouth, she wiped it clean with her thumb. Old habits die hard.
Son's Point of View: The Education
It was our first time going to the lab together as a family. By now, our tight-knit family had almost become accustomed to twice-a-day nursing on mom's voluptuous breasts.
It always stayed 'professional,' as strange as that may sound. Mom was adamant that everything be done by the books, properly. I could tell how conflicted she was about the feeding. Each time she'd have the same tense expression on her face. But afterwards, it was followed by a look of immense relief.
My sister and I could tell that mom had orgasms, but we avoided conversation about that detail to spare ourselves the awkwardness.
Finally, the lab partially opened with only 'essential' employees present. It was quiet and we headed straight to the doctor's office.
Reaching our destination, Dr. Kravchenko greeted us warmly with a strange expression of delight on her face. She was a middle-aged Ukrainian woman who looked incredibly professional and spoke graciously. Plaques and awards decorated her wall, so she was clearly involved in important work.
Mom handed the doctor small storage bags full of chilled milk she had collected before Abby and I helped with lactation. The doctor immediately had an assistant take them away, putting them into an industrial grade laboratory refrigeration unit.
"Thank you for the milk," Dr. Kravchenko said with her lovely Eastern European accent. "You look glowing and radiant, even more since the last we met."
Blushing, mom appreciated the comment and we were all formally introduced.
After spending a moment getting to know each other, we went inside the doctor's office (at her insistence) and she closed the door for privacy. My sister and I sat on the seats. Meanwhile, mom sat on the exam table while the doctor prepared to conduct a medical examination.
"You're very lucky having these helpers," Dr. Kravchenko smiled, washing her hands with soap, then drying them with a paper towel.
Mom returned the smile, "Well, I'm very blessed in that regard. It's been quite a journey to say the least."
The doctor stood in front of mom and stared deeply into her eyes. It felt oddly intimate.
"It's time for your exam, Elizabeth. Based on everything you've told me, I'm sure you must feel comfortable exposing your breasts in front of Ray and Abby. Do you mind if we begin?"
"Go right ahead," my mother said quietly.
This time we had an audience and even though Dr. Kravchenko was a medical professional, it still felt awkward.
"Excellent. Now, tell me how your breasts are feeling?"
As Dr. Kravchenko spoke, she casually unbuttoned mom's blouse, as if nudity amongst family was so natural. Mom's bra was exposed and she seemed to breathe a little faster.
"They feel constantly swollen," mom admitted. "Your advice on having Ray and Abby becoming my assistants was extremely helpful. At-home breast pumps are practically useless; but their mouths are very efficient."
The doctor nodded before removing mom's bra and revealing her milk-filled breasts. She then reached into her pocket and removed a small measuring tape.
"Let's see if there have been any changes in your dimensions, since your last visit."
Dr. Kravchenko held the free end of the tape to one side of mom's left nipple and measured the size of her dusky nub. She then repeated the process on the right.
"Hmm, your nipples have grown in size."
Then the tape was used to measure the size of mom's areolas.
"Oh my. This could be a very interesting turn of events."
The excited Ukrainian woman walked over to a storage cabinet and removed a device that looked a lot like a typical kitchen scale. She went back to mom and lifted my mother's right breast and put it on the scale. The weight was recorded on a ledger, then the left breast was weighed.
"This might be a major breakthrough. Your breasts are much heavier. Perhaps human saliva on the nipple augments the medication. The question is, does it need to be genetically compatible saliva?"
"I know it's plausible. Since I started breastfeeding, there have been more changes with my body."
Dr. Kravchenko tapped her right index finger against her chin, while deep in thought. She seemed to settle on a new theory, which made us all uncomfortable.
"How about sexually? Has breastfeeding helped with the increased sexual needs you experienced?"
Mom fidgeted before answering. "Nothing has changed in that regard. I still have these strong urges, but I've been able to keep everything under control for the sake of Ray and Abby."
"I disagree. It's fundamentally important to our research that your hormones lead the way, because we also need to understand your mental/physical connection. You agreed to that when signing on for the study. Now, tell me the truth, Elizabeth. Did you climax while your son and daughter drank from your breasts?"
Mom nervously looked at Abby and me. "I think I was able to hide it. I doubt they even noticed what I was doing at the time. But yes, it happened on several occasions."
At that moment, I wondered if mom was living in a hormonal fog to think I hadn't noticed her orgasm on the couch twice a day. It wasn't just the smell of her needy pussy that caught my attention. Her body practically convulsed every time she came. Sometimes, she had two or even three climaxes per breastfeeding session.
Mom was pretty unsettled and I felt sorry for her. Unfortunately, Dr. Kravchenko was just getting started with this line of questioning.
"Ray, let's start with you. Tell me, did you notice your mother having orgasms while you fed from her breasts?"
Feeling embarrassed, I managed to mumble, "Uh, no..?"
Dr. Kravchenko's face reflected skepticism and she continued to probe.
"I'll take that as a 'yes.' Now be completely honest, did you become aroused when breastfeeding from your mother?"
How could I admit that when I finished suckling on her tits, I'd go back to my room and masturbate? I don't know if it was the taste of her breast milk, watching her give into strong sexual urges, or the aroma of pussy juice that worked like a powerful aphrodisiac, but I jacked off thinking about all three. Hopefully, she hadn't seen the bulge in my pants that appeared every time she bared her titties.
"No, I've never done that," I fibbed. "It was always professional."
I briefly glanced at mom and noticed she was rolling her eyes. Had she noticed my erections?
"Ray, honey, it's important to be honest," mom gently chided. "Scientific research depends on good data. If I can do this, so can you. Go ahead and tell Dr. Kravchenko that you masturbated after every session."
"Mom, that's private," I gasped.
She huffed, "You were practically bursting out of your pants every single time. That's hardly private. Plus you scurried to your room after feeding and closed the door. What else would you be doing?"
"Ok, fine... I got hard from drinking mom's breast milk. What else could I do? Mom's nipples are epic."
Dr. Kravchenko was busy recording the conversation in a notebook. Thankfully, she didn't even glance my way during the exchange.
Then, the doctor turned her attention to Abby, who seemed overly interested in the diplomas displayed on the wall during my interrogation.
"How about your daughter?" the doctor asked. "Does she get aroused during the feedings? Does she masturbate like her brother?"
Abby's head jerked up and she grimaced in shame. I sat back in a chair, ready to watch the show continue now that I was off the hot seat. Mom seemed more uneasy with that question.
"Yes, Abby also gets aroused," mom said. "She's just better at hiding it."
My sister looked like a deer in the headlights. "Mom, how do you know?"
"Sweetie, you finger yourself every time your mouth latches onto my nipple. I'm your mother; I know these things. It's natural. Don't be embarrassed by your sexual urges."
Dr. Kravchenko smiled, "My thoughts exactly. All it means is that they are healthy and vibrant."
One part of me was embarrassed that they were so openly discussing my accidental erections and Abby's arousal during all the breastfeeding sessions. We had never talked about sex or anything remotely close. We're a normal, everyday family. I guess that's why the doctor seemed so interested.
But another part of me was sorry I missed out on watching Abby as she tried to get off on mom's titties. If I had noticed at the time, I'd probably have cum instantaneously while breastfeeding from our mother.
Dr. Kravchenko contemplated everything. "How interesting that all of you were similarly affected in terms of your sex drive. It sounds like none of you had control over your urges."
The three of us looked at each other. Instead of shame, we all seemed relieved by a shared excuse from the medical professional. At least we were in it together. And the idea that it had been 'out of our control' was highly convenient.
"Though we haven't yet discussed this, I think we should move forward and explore this fascinating new development. It could be fun... errr... educational for your family."
Mom slowly nodded. "I brought Ray and Abby here so they could learn. What did you have in mind?"
"Nobody is in the lab right now and I think it's best if we finished today's research over there. Elizabeth, leave your top off. You'll be getting naked soon."
The look on mom's face was priceless. I'm sure this was the first time she had ever been asked to walk topless around her workplace. She seemed even more dazed by the fact that the doctor wanted her to be completely naked. Just thinking about it made my cock stir in anticipation. At that point, I knew trouble was around the corner.
Looking at Abby, I knew she felt the same.
Daughter's Perspective: The Breasts
Like most college graduates, Abby had some experience with sex. Over the last four years, she had three partners and most of her sexual trysts happened in a dorm room. Sex was no longer awkward for her, but she knew her limitations and that there was a lot to learn.
During their 'sessions' at home, mom would only expose her breasts and usually placed a towel on her lap to avoid a mess. Abby wasn't sure why her arousal was so affected by feeding from her mother's breast. But the effects were undeniable. Her lactating mom made her pussy wetter than any guy from her past.
Now, watching her mother's current state in the lab caused an even more dramatic reaction between her legs. Sure, sucking on her mom's tits always made her incredibly horny, but that was in the privacy of her own home (and later in her bedroom). Now, she was sopping wet from watching her topless mom parade through an empty research facility, while a physician watched!
Several lab stations occupied the large research facility. Abby was impressed with the way her mother proudly made her way through the laboratory, past the desks littered with bunsen burners and glass beakers. It was clinical, yet immensely sexual at the same time.
Over the years, there had been several times when she caught glimpses of mom in various states of undress. Typically, it was when mom had been in a rush and left her bedroom door ajar. Those instances had always been brief, but Abby couldn't help notice that mom seemed pretty fit for a middle-aged woman.
However, this was a completely different situation. Mom was a test subject and Abby almost felt sorry for her. Despite mom's stoic look, she must have been embarrassed. Any normal person would be.
Dr. Kravchenko led the way to the back of the room, where another exam table was located. This particular device was equipped with stirrups, like those found in ob-gyn offices. After covering the table with a clean sheet, the doctor asked mom to lay down and put her feet up.
As instructed, mom hopped up on the table and then laid back. The doctor prompted mom to lift her legs and place her heels in the stirrups, which were off to each side of the table. Mom finally did as she was asked, and as a result, her pussy was on full display for anyone to see.
"Ray, please stand over here," the doctor said, gesturing towards a view typically reserved for a medical professional. "Do you like what you see? Be honest."
Abby watched her brother squirm, looking at the pussy of their obviously embarrassed mom with her legs spread open because of the device. The doctor displayed genuine curiosity, but this seemed a bit over the top for normal research.
"Mom's beautiful. I've always thought that."
"Do you want to fuck her?"
Ray's jaw dropped and mom had the same reaction. Nobody was prepared for the doctor to use that kind of language, let alone suggest sexual intercourse. It was shockingly unprofessional!
"I'd... I... if it's necessary," Ray stammered, clearly confused and conflicted.
The doctor nodded. "But it is. We know definitively that your mother's sex drive has increased from this study drug. Now, it seems that you and your sister are experiencing the same reaction. It would help to document the extent to which you have been affected. So the question is; has the drug impacted your mother's milk, or have you always been attracted to your mother?"
Ray wasn't even looking at Dr. Kravchenko. His eyes were riveted on mom, as she lay on display. Like a man on the prowl, he gazed at the exposed pussy with lustful intent.
"I...I..." He could barely say the words.
"Don't forget, we're paying a lot of money for this research. You and your mother have an ethical obligation to fulfill the agreement she signed. Just remember, it's for the good of society."
He took a deep breath. "Maybe it's both. I've always, you know, been attracted to her. And since I started sucking on her breasts... it's all I could think about."
"Do you want to fuck?"
"Yes, I do."
The doctor smiled. "Well then, don't tell me. Tell your mother."
Turning to look mom in the eyes, Ray whispered, "Mom, I want to fuck you so badly."
Mom didn't look upset or nervous. Actually, she looked at him with understanding, as if she was experiencing the same level of deviant desire. At that moment, Abby knew their family was about to enter new territory.
"Go on, do it. Remember your obligations to this study."
Hesitantly dropping his pants, Ray didn't even bother to remove them completely, letting them pool at his ankles. He stepped forward and used both hands to caress mom's crotch and thighs. Surprisingly - or not - mom didn't resist.
Abby noticed Ray must have decided their mom was ready for action, because he lined his cock up with mom's open pussy and lurched forward, impaling her roughly. Both mom and Ray groaned in unison when deep penetration had been achieved. They sounded relieved, yet anxious for more.
She had expected Ray to go easy on mom, since mom hadn't dated in a while. But no... he pounded her pussy with vigor, as if mom was a seasoned porn star. It looked like he wasn't holding back in the least. For better traction, he clenched mom's ass and pulled her to him with every thrust.
Mom's arms started above her head, but quickly grabbed onto the table for support and she encouraged Ray to keep fucking her pussy. Neither of them seemed to care that they were being closely observed.
Watching her younger brother -- who always felt more like a twin -- fuck their mother was startling. Abby tried to look away, but her mom's groans, grunts and shouts of "Oh YES!" brought her attention back to the obscene display. She was particularly struck by the force of her brother's lovemaking, causing mom's big breasts to firmly rock back and forth.
"Abby, your assistance is needed," Dr. Kravchenko said while taking notes.
She gulped, still looking on. "Me? I don't think I'm needed. Ray is... ummm... has everything under control."
"Your mother's breasts are ripe. The poor woman needs to be drained, especially now that your talented brother is pushing her to the brink. Go, relieve her plump, swollen mammary glands. Don't forget about your obligations."
Looking down at her mom's tits, Abby had never felt so torn. She wished she could blame her feelings on the study drug, but that would be a lie. Down deep, she knew the truth. She'd secretly been attracted to both her mother and brother long before this study began.
With every fiber of her being, Abby wanted to suckle on mom while her brother continued to ravage her pussy. And while she drained those tits, Abby planned to finger herself. The idea of them all climaxing together had her feeling weak in the knees.
As if in a trace, Abby approached her mother, drawn to jiggling breasts like a moth to flame. Finally, standing next to her mom, she extended her hand in an attempt to catch one of the fleshy globes as it bounced to and fro.
Her eyes roamed her mother's naked body, which was starting to sweat profusely from the hot incestuous sex. Then their eyes locked when mom looked at her, attempting to speak in between grunts and moans.
"Ugh! Abby... Oh God!... It's ok, sweetheart. OH! Follow your... heart. We're under contract to... ohh... give honest results... go ahead, my love. Ray! Please don't stop!!"
Unable to hold back any longer, Abby bent down and grabbed one of her mother's sweaty tits. It was almost like an erotic game to capture the elusive nipple into her mouth, since mom's boob was in a constant state of motion. She took her time getting it in, almost fearful of the sexual repercussion of taking things too far. After several seconds, Abby prevailed and latched on to the prize. A steady stream of milk immediately gushed into her mouth after the first suck.
Abby knew her panties were saturated, not just from watching her brother fuck their mom, but also from participating in this illicit and highly taboo act.
She felt mom's body pulsating while her brother continued to fuck with abandon. Remarkably, Abby managed to nurse steadily, giving mom continuous relief. Abby undid her own pants and dove deep into her underwear, finding her target. Round and round, her fingers circled her clit while she became increasingly aroused.
It took Abby by surprise when her mom spoke again.
"Abby, lower your pants and... UGH! Let me help you find release, GOD!"
Her mother was definitely in the throes of ecstasy. Following the suggestion of her mom, Abby managed to shimmy her pants down past her hips. Then she returned to fingering herself, unsure of what to expect next.
Taken by surprise, she felt her mother's hand wrap around her leg and work its way up into her most intimate area. As Abby worked her own clit, two of her mother's fingers pressed their way into her sopping channel.
Abby mentally took a moment to appreciate what was happening here. She was being fingered by her mother, from whom she was breastfeeding, while her brother fucked their mom's pussy. It was a circle that would change their family forever.
Sucking like her life depended on it, Abby continued devouring the breast milk while her pussy was being stuffed with two of her mother's digits. Far from feeling uncomfortable, she reveled in the erotic moment. Their family bond had never felt so strong.
"I'm going to cum," Ray moaned, as if on cue.
Mom winced and tried to make a quick decision. "Do it... on my..."
"In your mother's vaginal canal," Dr. Kravchenko interjected. "I'd like to study the effects of incestuous insemination."
Looking at her mother's contorted face, Abby saw an internal conflict after having been blindsided by the doctor's request. Ray kept on thrusting, fucking mom deeply and without a hint of caution.
She watched her brother focusing intently on the doctor's suggestion. Ray was positioned over their mom, thrusting with everything he had. When she heard her brother whimper, she knew he was already filling mom's pussy with warm cum.
And when she saw mom's toes curl on the stirrups, while her sweat covered body trembled, she knew mom was cumming at the exact same time. Abby sucked mom's nipple throughout the ferocious mom/son orgasm, which made mom cry loudly from the overwhelming full-body stimulation.
Like a trooper, mom continued to thrust her fingers into Abby's pussy. As her mother climaxed from Ray's forceful fucking, Abby also succumbed to an orgasm of epic proportions. It was like an incestual chain reaction had been triggered and it was mind-blowing.
Sensing the job was done, Abby gave a final suck and pulled her mouth away, licking the leftover milk that was pooled on mom's nipple, and using her hand to wipe her mouth clean.
She saw her brother, who looked like he had just finished a marathon, slowly pull his cock out. Ray's once engorged penis was spent, left dangling and soft. It was completely covered in a cum and squirt mixture, and a trail of sex fluids connected Ray's cock to mom's pussy.
In the end, she saw her previously traditional mother laying there exhausted, covered in family sexual fluids. Sweat dripped from all of mom's pores and excess milk pooled between mom's chest. When mom let out a small moan, a trail of leftover fluids gushed from mom's vaginal canal and onto the floor, courtesy of Ray's handiwork.
"Bravo," Dr. Kravchenko said with a deviant smile. "My masterpiece."
"I'll never be the same again," mom said in a low voice, as if she had just been resurrected.
The doctor smiled, "You're better than you ever were. Think of the contributions you've just made in the field of human sexuality."
It was true. Abby had read all of the documents that mom had been given regarding this experiment. Mom was a part of a game-changer, and Abby was thrilled to be along for the ride.
Looking at her brother's wet cock, she knew he agreed. Mom was still in a puddle of her own making. As a tight-knit family, they smiled at each other as mom looked for their reactions.
Not only were they all part of a groundbreaking research program, their bond as a family had become unbreakable. She watched their naked mother smile and hold her arms open, signaling for them to come closer and embrace.
Abby was a young woman who loved giving hugs, so she tended to hug mom more than Ray did. She was the first to hug their naked and sweaty mother, as mom continued to lay on the medical bed with her feet still in the stirrups.
Nuzzling her face next to mom's, Abby didn't care that her clothes were wet from mom's milk and sweat. Ray came over and hugged mom on the other side.
When their mother puckered her lips, Abby was the first to plant a kiss. It was their first time kissing each other on the lips and it was tender, like the kind you'd see on family friendly sitcoms. Mom turned her head and extended the same kiss to Ray, who accepted it and kissed her back.
Mom stuck her tongue out and returned to Abby. They shared a wet tongue kiss, which was something that was never intended to be part of this clinical study. But there it was. Not wanting to be left out, Ray joined the sensual moment, sticking his tongue in between theirs.
The three-way kiss was loud and sloppy, filling the lab with lewd sounds. Abby was positive she heard Dr. Kravchenko masturbating in the background, but her attention was completely focused on her mother and brother as they all enjoyed the benefits of a loving family.
