The sound of an old timer began to ring in the kitchen as a white female anthropomorphic goat wearing a purple dress began to make her way into the room. This wasn’t any normal goat, this was the queen of the underground world that resided below the surface. She was without a king due to the underworld complications but she definitely was not alone!
A small little anthropomorphic goat was sitting in a plush comfy chair by the fireplace reading away at one of the books he got off the shelf. His eyes stayed glued to the book while his mother came around the corner with a plate in hand.
"Asriel, you must really be enjoying that book if the smell of my butterscotch pie didn't distract you!" She said as the sound of a plate being sat down on a coffee table finally got his attention.
"Oh y-yea, I-I've been catching up on those new books you got a while back." He stated as he finally put the book down. His mother Toriel had a plate of her own as she sat down on the other chair across from him. They sat there quietly and as they both began to enjoy the pie that she made. Asriel sat there eating away while he seemed to be lost in thought and his mother gazed upon him and took notice.
"What's on your mind sweetie?" Toriel asked with a questionable look on her face. Her son looked up while he finished the last piece of his pie.
"Mom, what does Impregnation mean?" He asked as he looked into his mothers eyes. Toriel's eyes got wide and her cheeks began to become flustered and for the pie, well it became obviously hard to swallow!
"W-Where did you h-hear that word!" She exclaimed while forcing the bit of pie she had in her mouth down her throat. 
"I read it in the book right here." He replied as he wondered why his mother looked flustered. 
Toriel looked over at the book that sat on his lap and noticed that the cover of the book showed an egg with a few sperm swimming around it while one single sperm was making its way inside it. Toriel forgot that she even had that book but her mind was racing around to try and give her son an answer. She soon began to get flustered in not just her face but her nether regions as well! The thoughts of the sexual topic made her realize just how lonely she has been and it was making itself known as her nether region became more damp. She crossed her legs and tried to compose herself finally responding to her confused son.
"W-Well son, I have to ask you this before I can answer t-that b-but d-do you know what s-sex is about my child?" Toriel asked as she began to fumble through getting that sentence out.
"I-I read some things about it but I never really got to ask any questions about it." Asriel mentioned as he looked over at his mothers figure as she was setting her plate to the side.
"W-Well tell me son, what all do you know about s-sex?" Toriel asked as her nethers began to twitch producing more arousing juices that began to dampen the chair she was sitting on. She was really starting to focus on keeping her composure for her son's sake.
"Well I know that boys and girls are obviously not the same, and I've never really seen any books that showed more about female parts and male parts." He replied as his eyes darted at his mothers breasts. Toriel noticed where his eyes were looking and it startled her so she stood up and grabbed her empty plate and walked over to Asriel and grabbed his empty plate.
"L-Let me take these to the kitchen real quick and I'll be back to talk to you some more about this sweetheart." She stated real calmly so she wouldn't worry about her son. She moved by him and picked up his plate and then made her way to the kitchen. Asriel sat there quietly and watched his mother go into the kitchen and as he looked over to his mom he noticed a dark spot on her dress that was right below her bottom. He soon noticed a scent in the air but couldn't quite place it but as the scent lingered in the air he noticed a warmth wash over his body. The warmth made him squirm a bit so to distract himself he began to look around the room while awaiting his mothers return. His eyes soon landed on the comfy cushioned chair that his mother was sitting on, he recalled that it was the chair that she would sit on for napping or she would be reading a book but he noticed it was specifically her personal chair. The eyes of the curious goat soon gazed on the dark spot that was imprinted on the cushion. Like a moth to a flame he stood up and made his way over to the chair and as he got closer he noticed that familiar scent was getting stronger. The scent wasn't bad but it soon became pretty enticing and after a few seconds his nostrils got closer and closer to that damp spot on the cushion. A white nose soon rested above the spot where his mothers rump was once sitting and with a light whiff with his curious snout sent a jolt of lightning shooting through his body! The young goat felt dizzy but warm and excited all at the same time causing him to stumble back to his chair.
(A few seconds before)
Toriel made her way inside the kitchen and put the dirty plates she had in the sink. She stood there thinking about what happened and began to reflect on the conversation she just had with her son! The subject on her mind made her heart race and soon her breathing became erratic!
(Drip)
"W-What was that?" Toriel thought as she looked upon the floor. She backed up and what revealed from under her dress was a droplet of her own arousal that was leaking from her now wet nethers.
"O-oh my..." Toriel whispered to herself while trying to calm down. She couldn't come to terms with what was really going on through her own mind and being the only female with no mate and unsatisfied urges, she began to find the only other male in the house pretty attractive, but the only problem with that is the other male in the house was her own son! Confused and arousing thoughts went through head but the single mother knew that she had to go back out there and answer those questions! 
"Calm down Toriel, he's your son and you'll go back out there and answer any questions he has about s-sex..." She mumbled that little pep-talk to herself while walking out of the kitchen. What she saw next made her stop right in her tracks! Toriel was watching her son bending over and sniffing the cushion of her chair that she was just sitting in! Her mind went blank but her body was on autopilot and without realizing it she was rubbing herself through her own dress as she watched the erotic scene play out in front of her. The damp spot on her purple dress was no longer damp but now soaking wet! Once she watched Asriel sit back down, she pulled her fingers from her soaking nethers and soon after her brain kicked back in.
"D-Did he j-just..." Toriel stuttered to herself while making her way back to the chair. Before she sat back down she quickly grabbed the extra back pillow on her chair and sat it on top of her lap as she sat down so she could hide the mess she made on her dress. Once back in her chair she looked at her son and noticed that he was blushing at her.
"W-Welcome back m-mom!" Asriel spoke first while not knowing what his mother just witnessed him do. Toriel also noticed the book was resting back on his lap.
"Th-Thank you dear! S-Sorry I took so long! N-Now where were we?" Toriel replied while getting her thoughts in order.
"W-What I was saying is that I've read some stuff about males and females but never have seen anything on what makes them different." Asriel stated as he started squirming in his seat. What the poor boy didn't know was that his mothers scent was now stronger than ever and it soon started to slowly make itself known through his own body. Toriel watched in shock as the book on his lap started to lift itself up on its own. Asriel hissed at the sudden reaction of his own member coming to life for the very first time! His mother watched the scene play out before her lost in a trance.
"A-Ah! W-What's going on with m-my thingy!" Asriel yelped in pain as he lifted the book off his lap the member in his shorts started to throb with every beat of his heart. Toriel's mother instincts kicked in as she stood up and rushed to her son's side, getting on her knees.
"A-Are you okay, my child?" Toriel asked as she put her hand on her son's arm making sure he didn't injure himself.
"Y-Yea its j-just I don't know what's happening to my thingy?" Asriel replied while putting the book back on the coffee table. Toriel looked at her son's tent in his shorts and while doing so she took a deep breath and recollected her thoughts on what she must now do as a mother.
"Sw-Sweetie, Mommy's going to explain to you what your thingy is, okay?" She stated with a soft and loving tone that seemed to relax him a bit more. Asriel's thing still hurt  but mostly because of the amount of restraint that his shorts were causing.
"Ah! M-My shorts are hurting it mom!" Asriel yelped as he tried to grab it only to be stopped by his mothers hand.
"Don't touch it sweetie! I'll take care of your shorts, okay? Just sit there and let mommy know if it starts bugging you." She stated while slowly setting her son's arm back down by his side. Toriel took a deep breath and started to slowly put her fingers inside her son's shorts. The strained fabric was slowly being pulled down and as much as the loving mother tried she couldn't avoid brushing her fingers against her son's shaft.
"A-Ah M-Mom!" Asriel moaned in pain while his shaft throbbed against his mothers fingers.
"I-I'm sorry dear, they're almost off!" Toriel exclaimed as she started to pull a little faster. What felt like forever finally came to an end and once she pulled the last bit down her son's member sprung to life and when it did a thick rope of pre-cum shot out from the tip and landed right across his mothers face going over her mouth, nose and almost her eye. Asriel moaned in relief with his eyes closed as his member was finally free so it could throb freely for the first time. Toriel without Asriel noticing instinctively wiped her son's precum from her face and licked off what was around her mouth with her tongue. Her nethers soon became a faucet after getting the sweet taste of a young male in her mouth. 
"Oh, my child! You are quite endowed down t-there! I-I should tell you that your thingy is called a p-penis, my son." Toriel stated as she began to finally give her son some answers. Asriel finally opened his eyes only to see his mother pulling off the rest of his shorts so he wouldn't have to worry about them anymore.
"Th-That's my p-penis? It's really hard than it normally is and I feel really funny!" Asriel stated and out of pure curiosity he instinctively moved his hand to touch it but was soon met with his mothers who stopped it.
"Don't touch it sweetie, let it rest for a few, okay? This is your first time getting aroused and you have to let it grow." She explained while her eyes stayed glued to her son's pulsing rod she couldn't help it when it came to her own needs and with the one free hand she had disappeared under her dress. Toriel had her hand on her son's thigh while her face got closer and closer to her son's hypnotizing pulsating shaft and soon he felt his mothers warm breath blow over his shaft.
"O-oh m-mom, that f-feels g-good." Asriel moaned for the first time but not in pain but in pleasure and his mother noticed his change in demeanor. Toriel watched her son's balls start to drop and as they did another shot of precum left from her Childs tip but she instinctively caught most of it in her mouth while her son watched in shock.
"OH, W-What was that m-mom?!" Asriel asked as he watched his mother lick around her lips to clean them.
"That was called precum my dear, your balls right here just dropped and are now producing fresh sperm and because of that you also produce precum that helps your sperm get out of your testicles and through your penis when you have an orgasm." She explained while her son was in a hazy state of arousal. Toriel couldn't take her eyes away from her sons convulsing little orbs that began to swell little by little. The musk from her son became too apparent and with a lustful gaze she wanted to make sure her son was a health boy.
"Don't be scared my child, mommy's going to make sure you're a healthy young man." She reassured her own child and with one swift motion she ran her snout right against Asriel's now fertile baby makers. Asriel could feel his mothers nose inhaling the wonderful musky scent he was now giving off as a virile male. He looked into his mothers lustful motherly eyes as he experienced his first sexual encounter and then all the sudden he moaned out in pleasure as his mothers tongue enveloped his balls. His penis began to leak out more as Toriel used her tongue to guide her son's tasteful orbs inside her mouth. Asriel's eyes rolled into the back of his head while his balls were getting massaged by his mothers warm wet mouth and gentle tongue. Lustful instinct kicked in as he moved his hand alongside his mom's muzzle and that encouraged her to try something new. A humming noise could be heard in the room as Toriel began to hum causing Asriel to let out a long moan in pure pleasure. The vibration on his balls and shaft was causing a ton of precum to leak down onto his mothers muzzle. Asriel could feel his heart racing and something was starting to build up but he didn't know what it was.
"Ooooh Moooommy, S-Something's h-happening! I-I f-feel like I g-got to p-pee!" Asriel explained as his mother soon took a moment to get some fresh air.
"What you're feeling build up is called an orgasm, my child. It'll feel like you gotta pee but it's just your sperm and precum leaving your balls. Just let it happen my son, don't be afraid of it." Toriel coaxed as she ran her tongue down from her son's balls all the way up his shaft collecting all the precum along the way savoring the sweet taste of her own offspring and then swallowing it afterwards. Asriel watched his mother open her mouth wide open and with her tongue she guided her Childs lovely penis into her maw which rested on top of her tongue while his mom's hot breath and saliva drooled over his shaft.
"M-mom, I-I feel like I'm gonna explode!" Asriel shouted and with a smooth motion Toriel pulled her fingers out of the same birth canal her son came out of and with her soaked hand she guided it towards her son's face. Asriel's vision was starting to get blurry but it became clearer as he could smell something so sweet and musky near his face and he remembered the scent from before but it was more potent and enticing than ever before! He looked at the source of the wonderful smell and it was his mothers two fingers that were soaking wet with her orgasmic fluids and just like nature intended, he shoved his nose right against his mothers hand but his mom had other plans as she shoved her two drenched fingers into her son's mouth! Asriel was shocked at first but he soon closed his eyes and tasted the sweet love of the place that birthed him! With half-lidded eyes, Asriel ran his tongue all around his mothers fingers making sure they were clean but something else was off while he drank in his mothers juices he became more harder and more sensitive and as he made eye contact with his mother whose eyes were filled with the look of a loving mom and the lust of a female that he didn't know from the taste of her orgasmic fluids was in heat!
"I-I'm gonna-!" Asriel didn't finish his sentence as he clamped down on his mothers fingers and began to suck, he opened his eyes and looked at his mother's who never closed her maw and with one final humming breathe she looked at her son who never lost eye contact with her and soon after Toriel could feel her sons balls pull up on her tongue and then the sensation of his seed could be felt traveling from his sack through his shaft and his mothers tongue could feel the first pure white rope of sperm begin to shoot into the back of her throat.
"MOMMY!" Asriel yelled as he watched rope after rope of virile seed spill into his mothers maw. He looks back into his mothers eyes which have never left him and something else begins to form within his stomach like the sensation of butterflies as the saying goes. He starts to see his mother in a different light than before. A little spark shines in each of their eyes as they begin the true nature of marking each other spiritually. Unknown to the both of them a supernatural thing in the realm of the underground world that rarely happens is when two beings are in the act of true love can be forever binding and inseparable unbeknownst to them of what is taking place they continue to finish the passion of a mother and son bonding for eternity.
"Mmmmm." Toriel moans as the seed of her child begins to pool into her mouth. She winks at her son as she closes her maw and begins to swallow the wonderful sweet seed of the child she gave birth to. Asriel moans out in pleasure as his mother sucks his member of everything his little orbs could give! The sensation of his mothers warm wet mouth fully closed around his shaft finally over stimulated him causing the young child to drift away in sleep with a smile on his face. Toriel watched her child slowly fade into a sweet sleep as his member began to go soft inside her mouth she then slowly let her child’s member slide out of her mouth with an audible plop as it smacked against his lovely sac finally resting from its first ejaculation. Toriel eyed over her beautiful sleeping son who had a sweet smile across his face while he sucked away on his mother’s fingers like a pacifier. Toriel was so relieved that her son trusted her so much with what he just experienced for the first time!
“Sleep now my sweet child, I’ll teach you more of what you wish to learn.” Toriel whispered as she stood back up in front of her child as he sucked away at her fingers in peace. She watched her son with a sweet loving smile of a mother who just rocked a baby to sleep but there was something making itself more known. Toriel looked down at her robe and noticed that the bottom half of the dress was a darker shade of purple than the rest of the top. The free hand she had that wasn’t occupied in her son’s mouth slowly started to pull up her dress slowly exposing her legs little by little until she had her gown scrunched up to her waist exposing her dripping wet sex.
“O-Oh m-my.” The goat mom huffed as she watched her engorged clit twitch as the cool air brushed over her steaming sex. The female goat started to breathe heavier as the sensation of her fingers getting sucked became more apparently aggressive. Soon a thick clear strand of her arousal made its to the floor and all those years of sexual neglect came into fruition. Her mind became hazy as the visible steam of hot musk could be seen enveloping around the chair. She looked at her son whose nostrils could be seen flaring up taking in the scent of his lovely mother who was in fact starting her ovulation cycle.
“Y-You love the sweet smell and taste of your musky mother, don’t you?” Toriel softly spoke as her son hummed in a positive response like a mother singing a lullaby to her child as they slept. She couldn’t explain why she was no longer second guessing herself or worrying about what was going on; she was just filled with motherly love and lust that needed to be sated. Another thick string of liquid arousal made its existence known once more while it ran down from inside her thigh and as it glistened in the light a motherly idea began to form inside her mind. She looked at her swollen clit and it reminded her of a nipple that Asriel used to have as a pacifier when he was just a baby. Toriel trembled of the idea but she was just the right height and her son was positioned on that comfy chair just perfectly! She slowly pulled her fingers out of her sons mouth and then she gently positioned herself on the chair where her knees where beside her son and her hot wet nethers rested right above his face. The strong musky scent was like a magnet for Asriel as he unconsciously moved his snout straight to his birthplace.
"Ooo-oh, My d-dear c-child, h-help yourself." Toriel shivered as she felt her son's nose rub against her clit and as she watched her son feel the sensation of what felt like a nipple on his muzzle he instinctively latched on it like an infant feeding from a mothers breast. Her body went limp at the sudden sensation so she dropped her gown that she was holding up so she could catch herself by grabbing the top of the chair. The purple gown covered her son completely and the only thing that could be seen was two little pairs of white legs that hung out from over the chair. Toriel was grabbing the chair extremely hard as son suckled away at her clit and with the sounds of heavy breathing were also the sounds of heavy gulping. Asriel was drinking in his mothers orgasmic juices that was running down his gullet while his mothers love tunnel kept convulsing around his maw from the assault of the milking her clit was receiving. Toriel didn't know but her love nectar was more than just arousal juice it was something more potent because she was also ovulating. She never questioned why she was getting so wet unlike normal times it was just pure loving instinct.
"D-Drink up to your heart's content, my son." Toriel moaned while her young boy tried his best but her desires were manifesting into liquid form as it ran down Asriel's maw and his chest. Asriel's eyes were barely open as he tried to make out what he was looking at. The goat child was hot but not burning hot, he could only make out a light purple haze from the outside light shining onto the purple gown making the inside slightly visible. Hot musky steam filled up the small space of where he resided inside only being able to breathe in his mothers steaming hot musky scent that was even more intoxicating because she was now in heat. Light visible musk could be seen seeping out from the small open gaps that her gown was not able to cover up which was between her son's legs. Toriel's eyes began to roll in the back of her head and her claws were digging into the back of the chair clearly showing signs that it was about time.
"A-Azzy, M-Mommy's going to c-c-cu!" Toriel couldn't finish talking as her head shot back and her eyes grew wide and became white as she temporarily blacked out from the start of a powerful orgasm. Sounds of what sounded like splashing water could be heard from underneath her gown as the overflow of orgmasic liquid filled and soon overflowed Asriels mouth causing his stomach to swell as it forced its way into his mouth and down his throat. The poor child's brain was being overloaded with all kinds of sensations that finally broke his mind causing his whole body to go limp and go back to sleep. Toriel felt the sudden release of pressure from her nethers and began to regain her senses once more. Her claws pierced the chair from how hard she gripped the back and it ended up taking a second to pull them out so she could try and stand back up. Once free, she wobbled her way back to her chair and sat down so she could recollect her senses. The shock came upon her face once she laid her eyes on her child who was peacefully sound asleep but that wasn't why she was shocked. Her son's member was three times the size it was before and the same thing could be said for his testicles that showed great detail from how much they've grown. Toriel could not look away from those swollen orbs of his that convulsed and twitched due to the rapid process of all the sperm they were making.
"I-I did th-that?" She thought to herself while still recovering from a few seconds ago. The whole chair and her son was completely soaked and the bulge in his stomach made her feel proud knowing that all of it was from her. Toriel slowly began to go back into mother mode once she realized just how messy everything was.
"I need to get all this cleaned up and get you washed up and put to bed." She stated while regaining her posture and footing. Toriel managed to keep calm while tending to her child by getting him washed up all the while avoiding contact with his sensitive member. Once everything was nice and clean and she changed into some new nightly attire, she then began the process of putting her child to bed.
"There we go my dear child, all washed up, cleaned and ready for bed even though you've been asleep the whole time." She whispered, trying not to wake him up or startle him. Once her son was laying in bed, she gave him a kiss on the cheek and once she stood straight her eyes made contact with his semi flaccid member and still steadily growing sac that was swelling up with his life giving seed. Toriel made her back down towards her childs twitching sack and like a father kissing the pregnant belly of his wife she gave a little peck to his round sack causing it to convulse which made a little bit of precum dribble from the tip of his member.
"Sleep well my little sweet tadpoles, you'll be reunited with mommy real soon." She coaxed while inhaling her son's freshly washed musk that still smelled pretty strong still. Her nethers twitched but she was wearing some light purple colored cotton panties that were known on the surface as "granny panties" so she wouldn't be making a mess on the floor given her current situation. Toriel wanted to sleep with her child but knew she wouldn't be able to restrain herself so she decided to leave something behind so her child could know that she was still there in heart. The pair of panties she was wearing hit the floor and with a noticable dark purple spot on the thin part that covered her soakin sex. The kinky mother laid the damp part of her panties on top of Asriel's snout and just like that the sound and sight of her son's nostrils flaring up, intaking his mothers beautiful scent and with a smile on his face no doubt!
"Come to Mommy's bedroom once you wake my son, I'll show you all about what the word Impregnation means." Toriel whispered in her son's ear and then she began to make her way out of his bedroom. Asriel was unconscious, but he could make out the voice of his mother being heard and then soon the night continued as the young goat continued to have vivid dreams into the night. Flashes of light raced through the child's mind as he dreamed of what he could make out to be of white tadpoles swimming in the night sky and the stars were in the shape of round pink spheres with transparent outer edges with a solid pink colored center. He watched the white tadpoles swim into these pink like spheres and once they made their way inside the tails of the tadpoles would fall off and soon the sphere would start moving and changing colors on the inside. He would get closer to one of these pink spheres and in the reflection of one, he noticed that he himself was one of those white tadpoles and as he got closer to his reflection he soon made contact with the sphere which began pulling him inside. Asriel didn't feel scared once he was inside the sphere he actually felt a nice warm blanket lay over his body and soon everything began to get dark once again as he closed his eyes once more. A bright sharp oval light began to envelope his vision as he opened his eyes once more. The bright oval shape began to get wider but it would change its shape by getting wider and smaller but as he got closer to the oval shape it would get wider and wider until he pushed through the white now rounded barrier.
"There's my sweet baby boy!" A voice rang out in a blurry bright white room which began to become clearer for the eyes of a newly born infant. A sweet voice could be heard from a newly made mother who is finally being greeted with her newborn for the first time.
"Hey there my sweet dear baby, Mommy finally got you out of there! You've been so eager to get out of there just to meet me. Oh dear, I almost forgot to tell you your name! Welcome home Asriel!" Toriel cooed at her new born child while he reached to touch her face. Asriel soon closed his eyes as the wonderful dream continued to play out. And the other bedroom Toriel was sound asleep having a vivid dream as well.
"Don't be afraid mother, I'm never gonna leave your side for all eternity." The voice echoed into a starry night as a bed floated through the midnight space. Toriel opened her eyes and was met with the sight of her son kissing her but it wasn't a kiss of a son, it was the kiss of a lover. Toriel closed her eyes again while the both of them continued to play with each other's tongues but soon the child pulled away and Toriel opened her eyes once again. Asriel was slowly getting on the bed and he positioned his face against the very place he left years ago. Toriel grabbed the sheets as she watched her son begin to taste the comforts of his old place he used to call home. The sounds of moaning could be heard through the infinite space they floated in but what the mother truly desired once more came to light.
"I'm ready for you, my child." Toriel moaned as she looked down at her son who was now positioning his member right at her entrance. They both looked at each other in the heat of passion knowing what was next.
"I'm coming home mother." Asriel moaned as he went to push his member in, Toriel watched as her son's whole body morphed into a white sperm cell roughly a little smaller than he was. She watched the sperm swim up to her face as if it wanted a hug and she happily obliged as it wrapped its tail around her arm and nestled its head against hers. After a minute passed the sperm pulled away and swam its way down Toriel's body right down her thigh and soon it floated right above the entrance of her soaked womanhood.
"Please." Toriel moaned as the sperm looked up at her and then all the sudden it dove its head right inside her causing her to instantly have an orgasm which sprayed her juices all around the head of the sperm as it wiggled and made its way deeper and deeper into where it belonged. Toriel screamed in bliss as she watched the head of the sperm disappear inside her vagina and soon all that was showing outside was its tail that wiggled in a circular motion as it got deeper and deeper finally reaching her Cervix, it pushed through stretching it wide open and the last bit of the sperm's tail started rubbing against Toriel's clit which finally made her back arch up as the powerful orgasm took over her whole body which finally made her cervix open wider and soon the sperm was inside her womb. Toriel watched her belly get bigger once the sperm was inside and soon her breasts became larger than before and her motherly hips got wider than before. Toriel felt the sperm's tail slide out of her vagina now confirming that she was now pregnant. A smile washed over her face knowing well that her son was now back where he belonged. Meanwhile back in the other bedroom a sleepy goat child was starting to wake up from his lovingly vivid dream. Asriel awoke seeing the light color purple that filtered his vision and as he lifted himself up a pair of panties fell off his face onto his lap.
"Wh-What's this?" Asriel questioned as his blurry vision began to become clear and a pair of light purple panties came into focus. He soon realized what happened last night and soon he felt a twitch down in his nethers. Asriel looked in shock as his member and balls were incredibly larger than before! The young goat boy began to worry until the scent of his mothers musk wafted from her panties which caught the attention of his nose which calmed him down a little. He got out of bed and when his foot touched the ground he noticed he was standing in something wet and as he looked at the ground he noticed a trail of wet droplets that let out of his room. Asriel remembered something but he couldn't quite place it but all he knew was that he needed to go see his mother after he woke up! The door to bedroom was cracked open and he soon made his way out into the hallway. All the young goat boy had to do was follow the trail of his mothers juices that stained the ground that obviously led to her bedroom door. Once at his mothers bedroom door he noticed that it was cracked and as he slowly pushed it open he was met with a strong musky odor that embraced his whole being. At the foot of the bed laid his mother who had her legs spread apart and the edge of the bed was completely drenched in her juices. Asriel looked in shock as he watched his mother cry his name in orgasmic ecstasy as her juices shot across the room to the front of the door where he stood. Toriel looked up at her child with motherly lust and jumped up in embarrassment.
"A-Asriel! I-I'm so-sorry!" Toriel yelped as she tried to compose herself, but her son was not at all scared or upset.
"Don't be sorry mom, you don't have to cry anymore now that I'm here!" Asriel replied and with that his mother relaxed but the heated musk of a female that's well ovulated and in heat filled the air and soon it began to bring her son's member to life. Asriel was always a smart kid so after recalling his dream he managed to get an idea of what to do.
"Hey mom, I think I now know what Impregnation means now!" He stated with excitement, which invoked a moan out of his mother.
"D-Do you sweetie? C-Can you please show mommy how Impregnation works!" Toriel asked in an aroused tone as more of her thick juices squirted out a little from her remark. She watched her son walk up to her about a couple feet away from the edge of the bed and her eyes could not look away from her son's hard shaft that had a thick rope of precum that was hanging halfway down to the floor! Without hesitation she spread her legs apart revealing her brutally wet and swollen labia that had a light constant stream of her thick orgasmic juices oozing out of her folds. Asriel got closer to his mom and soon his member could feel the heat radiating from his mother’s folds that brought him here. Toriel could see just how close her son's cock was and the sight of those baby bearing balls of his made her imagination go wild causing her to go into another orgasmic fit which she ended up squirting her juices all over her son's member. The sight and smell of this invoked the lust inside of Asriel for the first time as he got closer to his mothers entrance his own member began to shoot a string of precum straight down the center of her folds that instantly squirted some more once it felt his precum. Toriel looked at her son with the pleading eyes of a loving mother and she was trying her best not to lose control but she wanted her baby boy to take the lead.
"A-As-Asriel, Wh-Whatever happens please don't pull out of mommy!" Toriel said pleadingly while trying her best not to cry and after that statement she witnessed her son place his member right on top of her belly which showed just how perfect of a fit he was for this mother. Asriel instinctively put both his hands on his mothers waist and just that physical touch made his mother spray more of her juices all over his swollen testicles. Toriel looked in her son's eyes as a tear ran down her cheek.
"Pl-Please s-son, Im-Impregnate me." Toriel whimpered and as she watched her son rear himself back she prepared herself by grabbing the edge of her bed tightly.
"I'm coming home, mother." Asriel said as he proceeded to shove his whole entire length inside his mother. Her birth canal easily welcomed back her son as he hilted inside of her as if it was waiting for him this whole entire time. Both Asriel and Toriel's mouth and eyes both shot opened wide and both of their eyes faded to white as they both were finally reunited. Asriel's penis was pressed against his mothers Cervix and like a mother greeting her son who just arrived home, Toriel's Cervix opened up and enveloped the head of her son's cock that rested inside her empty womb. On pure primal mating instinct Toriel wrapped her legs around her son which kept him in place and like a vice grip she managed to get more of his member deeper inside her womb. Toriel could feel her son's testicles begin to pull up as they dragged across her plump buttox closer to where they belong.
"IMPREGNATE YOUR MOTHER, MY CHILD!" Toriel screamed as the first fat load of virile sperm made its way through her son's shaft and she could feel every single detail as it pumped its way inside. The first shot built up right before her cervix due to how tight she was squeezing down on his member so she could ensure that not even one bit of her son's seed goes to waste! Soon the pressure gave way and the flared tip of Asriel's penis finally shot the first rope of pure white sperm that impacted the back of his mother’s womb.
"I'M DOING IT MOTHER! I'M IMPREGNATING YOU!" Asriel yelled as rope after rope of sperm continued to fill the very same place that he once resided inside of all those years ago. Toriel continued to have the most extreme climax of her life as she continued to spray her juices all over her child which ended up marking him with her scent meaning he now belonged to her. The feeling of her son's balls constantly convulsing against her bottom ended up driving her wild because of what it truly meant was happening inside her. Asriel moved his hand over his mothers womb as he could feel every single rope of seed pool inside his mother but what he didn't realize is just how tight his mothers cervix really was! Soon Toriel's womb was beginning to become full as every empty space was being filled with her son's liquid children. Another hand met Asriels as his mother put hers over his as they both felt the expansion of her belly as they grew and filled with his seed. Toriel's belly continued to grow and grow as shot after shot of sperm kept getting pumped into her womb. 
"Keep pumping them inside me, my child! Make sure you don't leave any of your sperm babies inside those balls! I want them all to Impregnate me so I can give birth to every single one of them!" Toriel yelled as she reached her other hand behind her son's head and then she pulled him into a passionate kiss. Toriel's tongue invaded her son's mouth and soon he invaded her mouth as well exchanging saliva while both their tongues wrestled with each other in a loving dance as a mother and son. Toriel opened her eyes and looked into her sons eyes as she watch them roll into the back of his head and right after that an audible slap of his sac lifting up and slapping against his mothers butt could be heard and soon her eyes rolled into the back her head as more ropes of sperm could be felt one after another being deposited into her bloating womb. The passionate kiss suddenly broke as her belly continued to grow and right soon after the sound of a pop could be heard between them as Toriel's belly button popped out. Asriel and Toriel were both holding each other's hands because the only thing separating them was that extremely Impregnated belly of hers.
"I think this is the last one mother!" Asriel yelped as he squeezed his mothers hands. Toriel noticed her son's balls jolted up really high and with one last pump Asriel's sac impacted his mother's butt one last time sending her juices everywhere showering them both with her love nectar. One fat glob of sperm made its way inside the same womb that created it which finally pushed Asriel's member out and as it popped out Toriel's Cervix never gave in and it sealed shut making sure not even one single bit of her child’s sperm leaked out.
"I never want this belly of mine to go back to normal ever again my son. Please make sure of that." Toriel stated with serious intent. Asriel laid on the bed next to his mother as they both admired their work by rubbing their hands all over her belly.
"Just think of all the sperm attacking my eggs son. A sons sweet sperm making love to a mothers beautiful egg ensuring complete Impregnation." Toriel lustfully explained as a white stream of white liquid shot out from the swollen nipple catching the attention of both of their eyes.
"I-I'm already lactating! Your sperm is going to make my body look so plump and beautiful, my child." Toriel stated with joy and excitement while her son was already passed out sucking away at her nipple as her breasts started to fill with milk.
"Sleep my son, and let your baby's settle in Mommy's Womb." Toriel whispered as she too soon began to fade into a deep sleep. Both mother and son laid beside each other in a warming embrace as Asriel continued to unconsciously breastfeed from his mother once more but now in a much more different light. Toriel drifted her hand to cradle her son’s head as he milked from her now enlarged breasts once more and as the night went on she fell asleep with dreams of bliss knowing now that she found a mate for life and from now on her needs will be forever sated by her own son, Asriel.
