So I’ve written some fapfics in the past. Been a while since I tried my hand at it, but I got my skills together and wrote up this little fic. I’ll post the warnings first, and then the story’s under the ‘Read More’ break.

[Undertale] A kind monster saves a boy who falls into the underground where the monsters are sealed. As the two get closer, their conversations get more interesting… [Anthro, COMPLETE, Footjob, M/F, Oneshot, Other, Phone Sex, Pseudo-Incest, Solo, Unknown Age Minor]

——————–

Mt. Ebott, 201X. Legends say that those who climb the mountain never return. A boy climbs the mountain, but trips on a vine, falling into a massive hole, deep underground. Cushioned by a bed of flowers that saved his life, the child explores the place he’s found.

Unfortunately, the boy meets someone who seems very friendly at first, but then turns out to be much less of a friend. Only by the appearance and power of another monster, different from the flower that attacked, was he saved. The goatlike monster, Toriel, sought to calm him down after the experience.

She protected the child, and sought to teach them how to live in the underground without being in any danger. Another monster was seeking the souls of humans, and she had seen others pass through and meet a grim fate.

She was determined to do all that she could to save this boy from that fate. She had taught him what she could, just like the others, but she didn’t want to bore the child too much either, so she sought to surprise him with a nice treat and some fun things to do. She left him a cell phone that he could use to call her…

—————————————————————————————————————————-

“…huh? Did you just call me… 'mom’?”

Toriel couldn’t help but blush. She had always wanted to be a teacher, but this child, he saw her as more? She had cared for the others before him just the same, but they never seemed to feel that strongly. Had she made more of an impact this time?

“Y-yes… is that okay?”

“Well… I suppose… Would that make you happy? To call me… 'Mother’?”

“Yes, it would!”

She still blushed as she heard how happy it made him. She wanted to keep him safe from Asgore’s plot, and if this helped out, then…

“Well then, call me whatever you want!” Toriel hung up shortly after that, hearing the child’s relief.

—————————————————————————————————————————-

*RIIIIING*

'Oh dear, it has been a little while…’

Toriel picked up her phone, and answered it.

“You’re really pretty…”

“…huh?”

She hadn’t expected the child to speak first, he usually let her go first. Wait, was he flirting with her?

“Oh, heh.. heh… Ha ha ha!” she giggled.

It was adorable, he thought she was pretty! Best to let the child down gently though.

“How adorable… I could pinch your cheek!” With a fond smile, she added, “You can certainly find better than an old woman like me.”

She didn’t want to make him feel bad, after all. Not that she was really old, at least for a monster like herself. But she definitely had a few years on the child in relative terms.

—————————————————————————————————————————-

About an hour later, Toriel realized it had taken such a long time to get the surprise ready. She’d better let him know she was coming for him… only to hear the phone ring right there! How had he…

“How did you get here, my child? Are you hurt?”

One quick glance, and she saw a few bruises. Much to her amazement and relief though, it appeared that her words had reached him; the stick he was carrying didn’t seem to have used much, if at all, and there certainly was no blood on it. She drew the child close, not noticing his blush as she treated the wounds.

“There there, I will heal you. I should not have left you alone for so long. It was irresponsible to try to surprise you like this.”

She blushed as she realized she was giving away the entire reason this had happened, letting the boy go after treating him.

“Well, I suppose I cannot hide it any longer,” she continued on, smiling. “Come, small one!”

She walked ahead, into the house in front of them, looking back to make sure he was alright. She was sure he would be surprised in a good way, with this comfortable house to live in.

“Do you smell that? Surprise! It is a butterscotch-cinnamon pie,” she said after he had walked in the door, the scent of the pie having permeated throughout the house since she baked it.

“Wow.. thank you!” he said, smiling again now since he had managed to make it through the ruins.

“I thought we might celebrate your arrival. I want you to have a nice time living here.”

“Living…” he murmured. “Living here, with you?” he asked, still looking happy, though a little confused.

She nodded, continuing, “So I will hold off on snail pie for tonight.”

Already moving on to the next surprise, she missed the small grimace he made at the mention of snail pie.

“Here, I have something else to show you,” she said as she walked into a small hallway.

She looked back to see him walking behind, and took his hand once more.

“This is it… A room of your own. I hope you like it!”

As they stood in front of the door, she reached down, rubbing his head gently. She did notice a bit of a blush, and a bit of a glance at her, but soon she smelled…

“Is something burning…? Um, make yourself at home!”

She quickly rushed off to the kitchen. She thought she hadn’t left the pie that hot! Luckily, she was able to save the pie before it was burnt. Figuring that it would be a little while before the pie cooled down, and that he would probably rest after coming through the ruins, Toriel went back to the living room, pulled out her glasses, and picked a book from the shelf. She had a curriculum in mind for the boy, and…

“Oh, hello there little one!” she said, somewhat surprised that he wasn’t taking a nap. “The pie has not cooled down yet. Perhaps you should take a nap.”

“I’m still… getting used to this I guess. But, thank you, I will.”

She smiled, looking back to the book “72 Uses for Snails”. She knew the book cover to cover, but it never hurt to brush up on her knowledge.

—————————————————————————————————————————-

'I guess the poor child was more tired than I thought,’ Toriel thought with a smile, glancing at the cell phone and seeing well over an hour had passed.

She set the book back on the shelf, and put her glasses away. Going back through the entrance and the hall, she took a peek in. She giggled softly at the sight. The poor child still must have had a bit of energy, because he was laid haphazardly on the bed, and a couple of the toys were strewn across the bed. But he was sleeping now, and the light was still on. She quietly crept past him, and turned the light off. Since he was probably going to sleep for a while, it wouldn’t hurt to get some sleep herself.

She headed out of his room, and into her own bedroom right next door. She placed the cell phone on the table by the foot of her bed, and pulled the robe off of her body. Being the only garment that she wore, her soft white fur was exposed in full. She sighed gently, smiling. The robe wasn’t really a burden, but she felt more comfortable in her sleep without it. She looked around the room to make sure nothing was out of place, doing a full rotation before lifting the blankets up and sliding her bare body between the covers. She closed her eyes…

—————————————————————————————————————————-

*RIIIIING*

Toriel quickly shot up from her bed, hearing the phone ring again. A quick glance showed that a couple more hours had passed… maybe she had miscalculated? Not that it mattered, her child needed something. Holding the blanket over her chest with one hand, she grabbed the phone and answered it.

“Toriel… m-mom… I really do think you’re hot…”

Hot was one way to describe the blush that crossed her face, the heat spreading from her cheeks down to her chest, as she tried to keep her cool. The boy was adorable… and… no, not especially after he called her 'mom’!

“O-oh dear, are you serious…? And after you said you wanted to call me 'mother'…” she trailed off, the words hard to find, but she had to straighten him out, right? “You are an… 'interesting’ child!”

“I… mom… I mean it…”

“But… my child… it isn’t right…”

“Why not…? I like you, you like me, and I want to be happy with you…”

It wasn’t like she could tell him he could find another girl. The chances of anyone else falling down were not very good, and she certainly was hoping he wouldn’t leave. He needed to be safe, and she needed… she needed someone to love.

“My child…? How… how do you feel right now?”

“I… mom… I feel scared, but somewhat excited. I’m shaking, and I feel really warm.”

“That, er, that is normal,” she whispered now, no longer holding the blanket over her chest. Her fluffy bosom was now exposed to the air, and while the breasts probably would have seemed large to the child, they weren’t massive.

“Are you okay, mom?” the child asked, now a bit calmer.

“Yes, sweetie… I’m just very warm myself. You should…” she trailed off, blushing again.

This was hardly appropriate, but that line was probably crossed long ago.

“You should take off your clothes while you’re in bed.”

She heard him set the phone down, and then the sound of his clothes hitting the floor, one after the other.

“I’m n-naked.. now what mom?”

“Oh my..” she cooed softly.

She was starting to get more flustered, but more excited as well, scooting back a bit as she parted her legs. Her soft, fuzzy slit was damp, a bit to her surprise, guilt, and excitement.

“I am too… if that makes you feel better.”

A sharp gasp from his end, and a soft groan of delight. She smiled lightly. Maybe she wasn’t as much of an old lady to him as she thought…

“Yes… it does mom.”

“Good…” she moaned softly.

Her free hand was softly playing with one of her breasts, as she focused.

“I bet you feel stiff down between your legs, mm?”

“Ye-yeah…”

“Mm.. put your hand around it, and pull back and forth a little bit.”

After a bit of heavier breathing, she continued.

“Feels nice, doesn’t it? Now imagine it’s my soft, fluffy hand, gently holding it as soft and carefully as I do the rest of you, Mother’s hand slowly pulling up and down your length.”

A louder groan came from the phone as her words slowly filled his head and sparked the naughty thoughts she was describing in detail.

“M-mother, yesss.”

“Hee-hee. I can imagine how eager you are… I did notice you looking at me, after all. Well… like I said before, I’m just as naked as you are. Other than a few spots, I’m covered all over in the same soft fur. The bottom of my feet are tough enough to walk these ruins without any need for shoes, but soft enough to enjoy the right touch.”

With a smile, she continued to tell him about her body, explaining anything she felt he didn’t know about, but keeping the excitement high. Her moderate breasts, topped of by the hard nipples from the excitement… Her plump rear, fuller and larger than the chest she had talked about… And her wet slit, glistening with her arousal.

“Now, my child,” she moaned softly between his grunts of pleasure, “I know you’ve been imagining my hand, playing with your hard cock. But mother is hungry… I’m kneeling at your bedside, pulling you closer, as I gently lick your tip. I can taste it, you’re so close already.” She licked her lips enough for him to hear, continuing, “Mmm… it’s salty, and I want more… Now I’m sucking the head into my mouth.”

She heard him grunt a bit more, tweaking her nipple and moaning, rocking back and forth a bit to alleviate her growing lust.

“Mmm.. hold on just a bit longer, my child. I’m sucking and licking that part, but I think the whole length needs mother’s loving care. That’s right, push it all the way in so I can make your whole cock feel good. That’s a good boy. Can you feel mommy’s tongue licking up and down every bit of it? Teasing the tip, caressing the shaft, as I suck on it all to make you feel so good? Now… don’t hold back. Let it go.”

Finally, a louder cry of pleasure, followed by heavier breathing.

“M-mom… I just…”

“Shh… that’s normal. I imagine you haven’t had pleasure like this before, so you weren’t expecting to have an orgasm like that. I’ll just have to wash the bedding is all.” She gave a small giggle, before laying back and continuing, “Most boys have to relax before they’re ready to go again. So now, I’m laid back on my bed. What would you like to do, my child?”

“Mmhh, um,” he mumbled, not sure of how to make her happy, like she did for him, though she expected this. “I want to make you happy… I’ll rub your feet.”

“Oh?” she cooed, smiling gently. “Do go on, tell me what you’d do.”

“O-okay. I’m at your feet, rubbing them gently to start with.”

“Mmm… Your hands feel nice, sweetie.”

“Ah, good. Um, I’m rubbing a bit firmer, up and down those tough feet of yours. I want to help you relax and feel good.”

“That’s a good boy, you’re definitely helping.”

“Hehe…” he chuckled. “I’m rubbing up your legs now, up to your knees.”

“Oooh, someone’s curious!” she teased him, smiling. “Go on, explore my body.”

“Alright! I’m rubbing up your thighs, and up to your belly. I can’t believe how soft you feel…”

Toriel shivered lightly, smiling.

“It’s nice, isn’t it, young one?”

“Yeah. Ah… your chest is even softer. I want to kiss you, mom.”

“Then do it, mmm…”

A soft smack of kissing sounds could be heard, and she smiled. He certainly was enthusiastic, and learned fairly quickly.

“I’m kissing down your neck, down to your chest, rubbing your tummy again. This feels so nice.”

“Ohhh, it feels great,” she moaned, playing with her breasts as he talked about kissing them.

“It’s so soft here, kissing your breasts all over. Your waist and your butt are soft too.”

She wiggled a bit at the thoughts, continuing to work with her tits. “Bring your hands around front sweetie…” she sighed in pleasure.

“Between your legs? Mmm, it feels really soft there too, and a bit damp..”

“Ah!” she gasped, moving her other hand to brush against her slit, holding the phone to her head with her shoulder. “Yes, that’s a good boy…”

“That must have felt really good,” he said, sounding happier at that. “I’m rubbing a bit more down there, and it’s even wetter. I’m still kissing your chest too, and I can feel you breathing a bit harder as I do.”

“Ohh… yesss my child…” Toriel gasped, rubbing and fondling herself a bit more. “That’s really good!”

“Kissing more and more, rubbing a bit harder, to make you feel good mom. Mmm…”

“Keep going-ah! I’m close!”

“Mm, I’m rubbing lower, and I felt a finger slip in. You’re so warm and wet there!”

As she plunged the finger in, the goat monster felt herself go over the edge, crying out in pleasure as she had an orgasm of her own.

“Ahhhnnn yes…” she cooed, her release short but strong.

“Are you okay mom?”

“Much… whew… better, my child. You did really good. Come into my room,” she teased him, still feeling lusty as she sat up a bit, legs spread.

Once the door opened, she hung up the phone, reaching over to put it on the table again, and sitting back once more as the boy came into the room. He was blushing a bit, but smiling too, as he set his phone on the other end. He was also erect, with a fine length for his age. Of course, it wouldn’t need to be big, he’d just need a good guide on how to use it…

“Come here, young one,” she said fondly, patting the bed, her moderate breasts wiggling a little from the motion.

He definitely seemed a little slackjawed, but obeyed with a smile, sitting at the foot of the bed.

Toriel giggled lightly, speaking again, “You seem to be surprised, and I’m happy to see that. I’m also happy to see that you’re a bit more grown-up than I expected myself.”

“Th-thanks mom…”

She smiled, rubbing his head fondly. “Not a problem sweetie. Now, since you did so good without knowing too much, let me teach you.”

She smiled eagerly at him, as her large feet reached and wrapped around his hard cock.

“Since you talked about making my feet feel good, I figured I could use them to make you feel good too,” Toriel giggled, slowly working her feet up and down along the child’s length.

She watched his face twist with the pleasure, as her firm, but tender touch brought him even more pleasure than he had gotten from his hands; so much so that he even humped at the feet eagerly for a couple moments.

“Hehe, easy now dear. We’ve still got the best part to get to,” she told the boy, smiling as she worked him a little bit harder.

“Oh, sorry mom…” he mumbled with a blush.

“Don’t be! There’s nothing wrong with a little enthusiasm.” She smiled as she soon stopped with her feet, motioning and telling him, “Come closer, my child.”

He obeyed with a small smile, seeming disappointed that she stopped like that all of a sudden. That didn’t last long though, as he felt her lips pressing against his, the goat monster kissing the boy lovingly as they embraced.

“Wow…” he mumbled after they parted, smiling.

As she lay back, Toriel had him lay down atop him, still with her smile. His stiff cock was pressed against her wet entrance, as he cuddled his head against her breasts.

“Mm… you’re such a good child,” she cooed, adjusting herself a bit. “Now, I need you to push your cock into me. And that bit you did, pushing against my feet? You want to do that here.”

Both of them looked down between her legs, as he slowly but surely positioned himself to fill her wet cunt. He nodded lightly, and then pushed in, moaning out as the warmth, the slick sensation of being within her… as good as everything before this was, this was on another level of pleasure, as he soon pushed his whole cock into her in his excitement.

“Ahhh! Yes, that’s the way…” Toriel gasped, shivering in delight.

Her moans only grew as the boy started to thrust in and out. He wasn’t too strong so he could only do so much, but she helped out, her pussy lightly squeezing around his shaft as he thrusted in, eager to give him as much pleasure as she could. Even after working out that first orgasm from him over the phone, she knew he probably wouldn’t last long.

“Mom! I’m almost…!”

“Hold on sweetie, stop for a moment,” she moaned, trying to see if she could work a little more from the eager boy. “Hold on to me,” she added, before rolling, now seated atop the child, her pussy still clenching his length.

She smiled down at him, her breasts looking larger from his new vantage point with the benefit of gravity. He watched as she started riding him nice and steady, not too hard, but enough to keep him close to the edge of orgasm without finishing the job. She was so close herself, she just wanted to share the moment with him…

“Nnn… Ahhh, my child…”

“Mom… I’m gonna do it!”

“Me too!”

She brought herself down a few more times, moaning in delight as his small load spurted within her. She gasped as her own orgasm overtook her, quivering with pleasure as they shared the moment. Finally exhausted, Toriel lay on her side next to the boy, who was almost asleep.

“I… love you mom.”

“I love you too… my child.”

Slowly they closed their eyes, falling into a slumber.

—————————————————————————————————————————-

The boy woke with a start, and looked around. This was his room.. he was dressed. Had it been a dream? A bit uneasy, he hopped out of bed. The pie scent was even stronger than before…? He looked down, and saw a slice of it waiting for him, still nice and warm.

Picking up the plate, he walked over to Toriel’s room, looking in. Her bed was perfectly made, and everything seemed as it had before.

“Maybe I’ll call her…?” he mumbled, reaching in his pocket, but it wasn’t there.

His eyes widened as he heard his phone ringing, right there on the table. After a couple rings, and with a brighter smile, he picked up the phone.

“Hi mom!”

“Hi sweetie, I was worried you were going to sleep for too long, so I just wanted to make sure you were awake.”

“Thanks mom! I just got up. I forgot which pocket I left my phone in.”

“Oh that’s okay sweetie, it happens. When you’re ready, I have a book I want to share with you,” Toriel replied.

“Okay, I’ll be right out!”
