///Story///
Your old place far above is now unreachable... Alone in the underworld, this kind monster named Toriel decides to take care of you. Given the chance of a new beginning, she takes you into her house, This place is awesome! With a warm bed, tasty food and it's lovely atmosphere complements your new momma's radiant personality, after a couple days you're already calling this place home, don't you?
"You're such a cute dude... are you gonna eat that?" Toriel says looking at the XL-sized slice of pie you just took a bite of.
It's caramel-ish taste is so damn good, this was the last slice but she's been so nice your heart compels you give it to her.
If it hadn't happened in front of your eyes you wouldn't believe she engulfed it whole, the bulge in her cheeks easily travels down her throat.
"What?" she says looking at your stunned expression.
Perhaps monsters have different customs and manners you simply don't understand, your thoughts are interrupted by the throaty belch Toriel just let out after standing up from the table and going to your chair to take your dish, as she does so, your arm has contact with her tummy, it feels very, very soft.
"Thanks kiddo, I know I ate the rest of the pie, but I'll make more la... oh?" Your blushed cheeks take her by surprise, ash she looks down at you, instinctively you give her belly a hug. She's surprised but curious at the same time, once you realize what you just done and shamefully retract, hands behind your back, she seems sad, feeling guilty for making you unconfortable, she raises her dress and smiles at you.
"It's okay if you want yo give me a hug... I think you're a pretty cute creature."
You slowly approach and hug her belly again, slowly caressing her and putting your ear against it. Her stomach growls and rumbles as it digests the queen-sized banquet she just had for dinner, but you don't want to be inopportune so you move aside, still blushed. She ajusts her dress and pats her stomach two times, you can see how the thick layer of fat covering it bounces with each impact.
"Well, I'll take a nap, see ya tomorrow, my child." She says walking to her respective room, and you decide to do the same.
Your bed is confortable, but, are you?
"I have a live up there" "Am I the only one of my species here?" "Will I see my family ever again?" thoughts trouble your mind all the cold night. After hours of tossing and turning, you take a desition: You'll explore the underground and climb your way up, regardless of the adversity. This place may be good, but it just isn't enough, you want to continue where you left, to return to how things where before you fell into the heart of this mountain. It wasn't perfect, but if you're good and patient, they'll get better... right? Taking the knife you hid in your drawer you exit your room, searching everywhere for the way out, the ruined city you saw from where you found the weapon must be beyond this house.
Did this house had a basement? It's all dark and quiet, as you walk you find what seems to be a door obstructed by a bulge and some old boxes, as you get closer, sudently two floating orbs of fire appear out of nowhere on both sides of the door, as the bulge rises up and takes it's cover off. Toriel is right in front of you, her curves exposed through her night outfit would be breathtaking if it wasn't for the confusion.
"I've heard your footseps echoing all over the house, no one stays for too long here so I guessed you would eventually end up here... Perhaps, this had to happen?" She says dissapointed.
Her word fill you with doubt and regret, as you're about to turn back, you remember your old life and decide to stay put. With resolve, you walk forward.
"Are you challenging me? I don't want to do this, but if you want to fight the world beyond this door, you'll have to face me first."
Suddently, multiple fireballs dance arround her rythmically, her imposing stature makes your small body shiver for a moment, with the snap of a finger, five of the seven fireballs fly at you! As you run forward and dodge them, only one thing is in your mind, the timing must be perfect to avoid the orbs protecting her, you dodge the last fireball and quickly take the knife out of your poket, your eyes meet hers as your war cry echoes in the walls surrounding you, with a jump, you slash the knife against her arm, after landing beyond her, you look back, is she... intact? Her expression changes to one of annoyance as you charge at her leg.
It is now, as the blade bends against her leg after each stab that you realize that the weapon in your hands wasn't a weapon after all... As you look up ashamed Toriel's stomach growls loudly, your ashamed smile doesn't disipate the dissapointment in her eyes.
"Guess it's time for a midight snack, don't you think, my child?" She gives you a condescending look after grabbing you by the arms, she opens her maw widely as you struggle against her grip, knowing your cries for help are useless you stop resisting, as her maw comes closer to your face and you stare at the black hole beyond her uvula you begin to feel a certain curiosity, she licks your face multiple times, covering you in her thick saliva as her stomach growls stronger, getting ready for the huge meal it craves so much. She fits your head into her maw, the wet cave is perfectly lubbed to let you in, she gulps again and again, your whole body slowly dissapears inside her, she kneads down and raises her head upwards, letting gravity do the rest of the job as you get further through her esophagus, after your shoes are already inside her cheeks, the monster goat slowly closes her mouth and gelicately takes the last gulp , now you find yourself packed tightly in a pool of glowing liquid, struggling against the stomach walls. Toriel lays down massaging and patting her now swollen belly.
"You pointed a toy knife at ME? I must recognise your courage, but you've been a nasty boy, you'll be grounded inside my belly for some hours to think about what you've done." Even soaked in her fluids and trapped, her feminine voice it's still heartwarming. You begin to massage the motherly goat's stomach from the inside, after some time, you hear her giggle.
"Do you know? The females from my species have very particular maternity habits, since we can naturally engulf preys so big, it's a custome for us that when a kid is being troublesome, we just let them stay on our bellies for a long time as a punishment, in that time our stomaches acid becomes totally safe, so don't worry" She says caressing her belly button.
You keep caressing her lovely when the glowing liquid surrounding you begins to bubble, as the minutes progress, her stomach begins to feel more roomy and the walls get tighter. Toriel presses her belly with both hands as it suddenty gets tigher arround you
"uuUUoOAAAARP!! Sorry sweety, this is a side effect of this, so you'll have to get used to it, hehe..." Her joyfull voice makes you feel good, perhaps, staying with her could be a good idea after all, what is it that you always wanted? A nice house, good company, a caring couple, its all here, now! Returning to your past to reach the future you want sounds like a good idea, but if you wish it, perhaps your present with her can become your future.
"Toriel, I took my desition..." You say as your voice is filled with something... determination perhaps?
