Chapter Four

In the dream world, Chara giggled as she gently massaged Frisk’s aching muscles, slender fingers roaming the shorter girl’s body.
“Wow, you did it…” Chara shook her head with a smile, as Frisk awkwardly lay in the flowers. Chara’s gentle touch was a welcome relief after the incredibly wild night with Toriel.
“...Mommy, huh~?” Chara teased, and Frisk blushed. “Sounds like you got a few more kinks than you even knew about…”
Frisk shyly glanced away. “I w-was just trying to provoke her, because I thought it might wear her out faster.”
“Maybe it did, but that could have backfired, and then you’d have lost your mind.” Chara nuzzled her, purring. “But… you didn’t. You’re just determined to get further huh?”
Frisk smiled a bit, then squeaked as Chara playfully gave her tits a squeeze, kissing Frisk’s collar from behind.
“Sorry~” Chara murmured, not sorry at all. “You’ve got a lovely pair I can’t seem to keep my hands off of~” She playfully massaged Frisk’s boobs, hands working and squeezing them, more gently than Toriel had.
“You… were kind of innocent, before you fell, huh~? A virgin?”
Frisk nodded. “Y-yeah. I knew about sex and um, stuff… But hadn’t really touched myself…”
“Aww.” Chara cooed. “Cutie. Well, mm, I was… definitely more loose than you, even before I fell.” She giggled. “But It was a long time ago, and things were different and I got chased away for being a harlot.”
“That’s sad.” Frisk pouted, shifting to nuzzle Chara comfortingly. The girl blushed, to Frisk’s delight.
“It’s just how it was, and things were much nicer when I fell down here~” Chara kissed Frisk’s forehead. Her soft lips trailing over the girl’s skin. “Monster girls are good company, if you can manage to keep your mind.” Her expression changed a bit. “Be careful. It’s only gonna get harder and they’re going to be more relentless from here.”
Frisk nodded. Chara smiled.
“Okay… that’s the unhappy heavy stuff out of the way… soooo~”
She pounced on Frisk, with devious lustful intent in her gaze. Frisk moaned and shivered.
When Frisk awoke, Toriel was in the kitchen. The human girl walked up behind the woman and gave her a hug. The furry monster lady laughed softly.
“Oh… Good morning my child.” There was sadness in her eyes, but there was some hope too. “...You’ve proven that you’re strong enough to survive out there…” She kissed Frisk’s forehead softly. “But you do not have to leave right away. When you do, however… You should know that the doors shall seal, and you will not be able to return.”
Frisk nodded and Toriel smiled, offering her some breakfast. The girl ate ravenously, before giving the motherly monster a lingering hug and kiss goodbye. She left, with a small bag with food for the trip, and a thicker, warmer sweater for the cold ahead.
Frisk stopped at the door. A familiar girl was curled in front of the exit with a smirk.
“Ooh, clever girl, survived without losing her mind, mmm?” Flowery giggled, groping at her own tits as she stared Frisk down. Frisk stood her ground, ready to flee if she needed to. The girl moaned, slowly. “Why not give up? Be everyone’s cumslut? It’s what you’re destined to be~” She gleefully showed off her cock, rubbing it. “It only gets harder from here, princess. They’ll rape you and rape you and rape you until you give in and lay there, broken and whining for more.
She cackled, giggling as she rubbed her own cock. “And once you break, I’ll be there to have my fun~!” With a moan, she came in a sudden spurt, before giggling and withdrawing into the earth, vanishing.
Frisk ran through the door and left the ruins, legs shaking.
It was a good thing Frisk had been given warmer clothes. As much as she liked plain, simple outfits that just so happened to nicely hug her curves, she knew they wouldn’t do very well in this frozen place… Snowdin. Cold, with snow.
Underground.
She wasn’t sure how but there was snow. Underground.
Still, it wasn’t all bad. She met a pair of charming, if odd, skeleton girls. Well “skeletons” are what they called themselves, but they had skin. Pale, soft white skin and black eyes with glowing lights hidden in them. They were near opposites in every way. One, laid back, semi-uncaring, easygoing, short and stocky- Her name was Lexia.
The other girl was tall and skinny, full of energy and excitement- she cared about everything. She was called Clair.
Were they… named after fonts? Frisk could swear she’d vaguely heard of fonts with those names. Still, they didn’t seem to interested in ravishing her. Clair, despite her height, seemed to be younger and more naive and not even know what it would have meant. Bubbly and sweet when she wasn’t cheerily telling Frisk that she was going to “capture” her.
And Lexia didn’t seem to really care enough. She just sort of wandered about and showed up ahead of wherever Frisk was going.
That wasn’t to say Snowdin wasn’t without its monsters who would try. The first one she met was a… dog girl? Her gaze wasn’t very steady, and she kept weaving her hair.
“Did somebody move?!” She barked, clambering out of her sentry station. “Was someone moving?! I can only see moving things…” She growled, her teeth showing. The lithe dog girl looked about, and Frisk blushed, seeing a tapered, canine cock emerging from her sheath.
“Don’t move…"
She couldn’t see Frisk, and soon her back was turned. Frisk crept closer, until she was right behind the dog girl. She reached around slowly and began stroking her cock.
“Yip! Something’s p-petting me!” She woofed, her tail wagging. Frisk bit back a giggle as she began sneakily giving the dog girl a handjob from behind.
“Something that’s not moving!” She yipped again, bucking her hips and a spurt of cum shot out. “I-I.. it wasn’t moving… I-I’m gonna need some treats for this…”
She dove into the station to hide. Frisk shook her head with a smile, and resumed on her way.
Frisk was ambushed a while later, when she was jumped from behind by the next Monster Girl- another dog, this one smaller and fluffier, with a grin on her rather cute face. She didn’t speak, just gave a playful growl and began to tug Frisk’s pants down. She squeaked, and squirmed, feeling the cold snowdin air on her body for a moment, only to be replaced by the doggy-girl’s warm body, and then by more warmth as her pussy was invaded by the girl’s cock.
She wasn’t very big, but she was very vigorous as she humped Frisk’s pussy, naturally, doggy-style. Frisk moaned and took several heaving breaths. She was trapped on her hands and knees in the cold snow, the puppy-like enthusiasm from the wild girl atop her causing her to be jerked forward with each needy thrust.
Frisk whimpered, as the other girl humped away, eagerly, feeling a swelling at the base of the puppy-girl’s cock. Frisk could feel the dog girl’s knot swelling as it pressed against her pussy. Frisk uttered a little mewl as dog girl’s arms wrapped around Frisk, pulling her backwards while pressing forwards. With a pop the knot forced itself inside.
The dog girl yipped happily, humping fast and wild, her thrusts no longer as long, but they were much more rapid, with the thick knot tying them together. Frisk bit her lip, feeling the cock throb. Before long the puppy-girl’s seed was flooding into Frisk. She gave a gasp, as she was pinned, feeling the cum flood her pussy.
After a while, the doggy girl’s knot deflated, and she tugged out, gently nudging Frisk’s pants back up to keep the girl from freezing, but not before giving her firm rump a quick squeeze. The girl gave another cutesy bark sound, licking Frisk’s cheek, before darting off into the snow. Frisk sat up, a little dazed, but after a moment, she felt a rush of pleasant energy, and found the strength to stand and continue through the biting cold.
Frisk was rather surprised when the orb Clair placed in her hands suddenly shot out, down into her pants and nested itself tightly against her clit, but she quickly uncovered why, when she brushed a wall of the electricity maze. Frisk gave a startled scream, as the shock went right into her. It hurt, but it also… felt really good. Frisk shuddered, biting her lip. Clair didn’t seem to notice the secondary effect of the shock and was giddily posing.
“You see human?” She sounded very excited. “My electricity maze is impassable!”
Frisk chewed her lip, flushing as she carefully continued to maneuver through the maze, taking her time. Each mistake led to her uttering a squeal as she was shocked, her pussy drooling as the apple-sized orb zapped her clit. She made it, almost at the end, legs shaking violently.
“Oh-ho~!” The oblivious skeleton girl beamed, bouncing. “You solved it so easily~! Too easily…” She giggled, seeming to have not even noticed Frisk rocking on the brink of an orgasm. “But the next puzzle will not be so easy~! It was designed by my sister!”
The girl cackled and fled, followed by her sister who gave Frisk a wink.
“Nice job kid.” She noted sardonically. “My sis seems to be having fun. M’ sure you are too.”
Frisk uttered a whimper as Lexia strolled off. Nobody was around. Hesitantly, Frisk reached a hand back one final time-
She choked back a scream as she came from the electric shock, shuddering as her juices drooled over the orb.
I think I’m gonna keep this. She thought, digging the orb out of her pants and hiding it in her bag. Just in case I find a new way to activate it.
Frisk froze when she was ambushed by a pair of tall dog girls in cloaks. They couldn’t see very well, it seems. They stuck close, shifting to sniff and protect each other.
“What’s that smell?”
“Where’s that smell?”
They leaned close and Frisk squeaked, stumbling back. They sniffed again. “That smell…”
“It makes me…”
“...want.”
“Me too.”
Frisk squeaked as they both gripped her suddenly, pulling her to her feet.
“I want to share her with you, sweetie~!” One giggled to the other.
Frisk would have uttered a protest, but the robed dog ladies were already stripping Frisk, her clothes tumbling off, roughly groping and fondling her. She uttered a whimpering little moan.
“Rrr. No fur. So smooth~!” One play-growled, shifting her robes to reveal an erect canine cock, much larger than the puppy girl from earlier. Frisk opened her mouth to complain but was muffled when the cock was stuffed in her mouth.
Should have seen that coming. She realized awkwardly, bent forward and forced to take the large, tapered cock into her throat. The other robed girl giggled, before shoving her own cock deep into Frisk’s cunt.
“Rrf~ Tight and warm~ Soft~!” She barked to her companion, who giggled. The pair leaned forward and shared a deep kiss, before they went to work, lifting Frisk up and ramming their cocks into her, spitroasting the helpless human above the ground. Frisk squealed, muffled as the dog ladies fucked her between them, slamming their knotted cocks into Frisk’s holes. She shuddered and moaned as they noisily humped the girl dangling limply between them.
“Nnhn~ This smell feels so good~! She’s slobbering all over my cock~!”
“Mmh~! She’s tight too~! So wet~!”
Frisk moaned, and realized she was indeed eagerly slurping on the cock. This place was really changing her. She shuddered as the cocks slammed into her, both thrusting in tandem with one another.
Frisk cried out, the girl’s effortlessly shifting their rhythm of thrusts to another speed, still in perfect sync- each thrust in perfect time with one another. She shuddered in alarm as she felt the knots swelling, larger than the other dog girl. Could she even fit those knots? Her eyes widened as the first knot forced itself into her pussy, and the second one managed to force her mouth around it, trapping the cock in her throat. Frisk gagged and whimpered cutely.
“Hhmmm~” The girl stuffed down Frisk’s throat panted. “Gonna cum~”
“Mmmmh~” The second panted, dragging her partner into a kiss. “So good~ Me too~”
Both cocks throbbed, and fired off their loads. Frisk whimpered, swallowing as much as she could, choking down the cock in her throat. Slowly, she felt the knots deflate and she was dropped into the snow. The two girls seemed rather enamoured with one another and were distracted. Frisk re-dressed, her clothes wet but still better than being naked, and continued on her way, glancing back to see the girls nuzzling and kissing eagerly.

A/N: Gonna cut it here. It’s getting a bit long. Enjoy.
