"Frisky Frolick"

Before we start:

- Frisk is 18+
- Chara is 18+
- This features characters from the game Undertale doing things for an 18+ audience.
- I will take any criticism. I mean it.
- This is merely experimental since this is the first time I'm posting anything in the quicksand community. Howdy, by the way :>

And the story begins:

Chara: "Frisky?"

She looked around for the risky Frisk, but Frisk had something planned that Chara would not quite expect right away. She kept herself well-hidden, but also noticeable enough to allow Chara to follow her through the thick unknown woods.

Chara: "Here, Frisky Frisky! Come out, you!"

Frisk was smiling and traversing with excitement. She felt excited to play around with her lost friend.


Chara aimlessly chased Frisk, with limited success, but enough to be able to keep up with her. She was a bit nervous that they were going to get lost in the tall vegetation, but she felt like she was enjoying herself at the same time. She must've guessed Frisk was enjoying herself as well, because she heard Frisk's cute giggle as she was running a few times.


Chara kept running, and Frisk gets ready for her plan to initiate. She runs ahead a bit more and tries to make as little noise as possible. She goes around a pit of mud until she is on the opposite side of Chara's position. Frisk takes a stick and throws it to the other side of the pit into a patch of tall grass. Chara hears the noise and makes another move as if to continue her chase with Frisk. She ends up tripping and falling into the mud knee-deep and breaks her forward falling force with her hands.

The sudden contact with the soft, but thick goo surprises her. She pulls her hands out and her knees go under in the mud.

Frisk: "He he he, you have fallen into my grasp."

Chara: "..."

The silence worried Frisk a bit.


Frisk: "You didn't hurt yourself, did you?"

Chara: "Not at all, you freak. How did you find this stuff?"

Frisk: "I actually found it on accident. I was walking around the woods for a while and I stepped right into it. I thought I was in trouble for a bit, but I was able to get my feet out pretty quickly. Then I thought it might be a fun idea to let you see it for yourself."

Chara: "Is that why you stole my knife?"

Frisk: "Perrrrrrrty much."

Chara: "Perty much? Alright then. Also, you know I use it for only cooking now, right? I don't hate humans like I used to Frisk."

Frisk: "Nah, I know."

Chara: "Also, can you get me out?"

Frisk and Chara almost got too distracted from the mud situation. The mud has barely begun to consume Chara's shorts.

Frisk: "Oh yes, I must release the poor animal from my deadly snare."

Chara: "Sure doesn't feel deadly. It actually feels a little nice.

Chara moved her legs a bit to feel the mud more.

Frisk: "Does it really? Although, I guess now that you mention it, it kinda does look pretty good to for me to dunk myself into."

Chara: "Heh, dunk. Doesn't that sound familiar Frisk?"

Frisk: "Shut up. I thought I told you not to bring that stuff up anymore."

Chara: "Yeah... I know. Sorry. I must admit, I'm surprised you were able to even try sparing the lad with how much control I had over you."

Frisk: "Just goes to show how determined I really can be."

Chara: "Yeah, no kidding."

As they were talking, Frisk was looking for an easy way to get Chara out, but easy seemed out of the question. Being distracted with the thought of jumping in with Chara in the mud instead certainly did not help the situation. Meanwhile, the mud began to hungrily swallow Chara's thighs, which gave Chara a strange feeling inside of her.

Chara: "Hey Frisk, do you know how deep this mud is?"

Frisk: "Well... Not particularily..."

Chara: "What?!?"

Chara felt panicked to hear Frisk's answer, but she also had a feeling that Frisk was trying to play around with her.

All while still experiencing the new sensations Chara was feeling from the mud.

Chara: "Are you just trying to scare me? Although, I'm not feeling any solid ground still..."

Frisk: "You won't, at least not now."

Chara: "You really are trying to scare me!"

Frisk: "He he, that's what you get!"

Chara pouts and makes a sad face, which was quickly interrupted when the gooey mud took hold of Chara's groin. She had a look that said more than she knew: Shock, fear, excitement, and something else.

Frisk: "Are you okay? Is the mud cold or something?"

Chara: "No, it just... it feels really good. It actually feels quite the opposite of cold..."

Frisk: "Ooh? It... it really does feel good?"

Frisk was trying to imagine what Chara was feeling. She wanted to know much more about how Chara was feeling, especially considering how exciting it sounds. She started to get restless.

Frisk: "How good does it feel, Chara?"

Chara: "It feels... wait, you're not thinking what I think you're thinking, are you?"

Frisk: "I really want to join you and see how it feels."

Chara: "Frisk, I want to tell you to stop because we could be in danger, but I also don't want you to stop. I..."

Frisk: "Well, that's enough to convince me."

Frisk then proceeded to take off her sandals. Then she suddenly took off her shorts, which made her body feel very excited. She wasn't sure she was entirely in control of herself.

Chara: "Frisk! What are you doing?"

Frisk: "What? I don't want to get all of my clothes dirty..."

Chara: "I got my clothes dirty..."

Frisk: "You're shirt is still clean, mostly... You could take it off before it get's more dirty..."

Chara: "Are you crazy? I... I'm not sure if that's a good idea..."

Frisk: "You don't have to if you don't want to. I'm going to though..."

Chara: "No, I'm..."

Frisk's shirt was now off, which made her feel uncontrollably excited. Chara nervously proceeded to take off her shirt with her muddy hands, trying not to make her shirt more messy. After it was off, she threw the shirt away from them and the pit. She started to feel much less controllable and more excited. The mud was slowly swallowing her hips, making her feelings intensify inch by inch and has yet to make contact with her newly revealed skin above her shorts.

Chara: "Frisk, this is crazy."

Frisk: "I know and I love it."

Frisk was stepping towards the mud pit where Chara was closest. Chara was only a couple feet away, so Frisk could probably walk towards Chara easily before being unable to walk on the pit.

Frisk: "Okay. Here I come, Chara!"

Frisk begins to take a few fast steps until she is standing and facing Chara in front of her. She starts to sink in, which brings back when she accidently found this pit in the first place. Only difference is that now she will sink much deeper than just her feet. Now she can no longer remove her feet easily. She was in with Chara.

Frisk: "Oh gosh, I'm actually sinking..."

Chara: "You're so much higher than I am though. Can you pull me up some?"

Frisk: "I suppose... I don't see why not. Then, I'll be able to see your beautiful face."

Chara: "Why do you always flirt with me?"

Frisk: "Because it's funny, and I like flirting with you."

Chara was blushing.

Frisk: "And I like seeing you blush like a cherry."

Chara was easily embarassed by Frisk. Frisk grabbed Chara's hands and she began pulling her up. This resulted in her sinking down to just above her knees. Now Chara was at the same level.

Frisk: "Oh god... it... really does feel good."

Chara: "It does... it feels really good. And it just feels a lot better the deeper you go."

Frisk: "And you even have clothes... err well at least shorts and underwear on."

Chara: " And you have only underwear on... maybe I should..."

Chara reaches for the button on her shorts, which was surprisingly not covered by mud, but it was close to being covered.

Frisk: "Whoa Chara..."

Chara: "What? You took it off before I did..."

Frisk: "Yeah, but I'm really close to you."

Chara: "So?"

Frisk: "We'll both only have underwear on."

Chara thought for a moment.

Chara: "Well... I just... I just want to feel what you'll feel."

Chara proceeded to undo the button and zipper and slide her shorts into the mud. She had to push her shorts a bit deep in the mud and get her legs out of her shorts, so she can get the shorts off and out of the mud. She notices that she had lost her sandals a while ago. She and Frisk were up to their thighs, and they now both wore the same amount of clothing.

Frisk: "Something about this... feels unsettling, but also really... really good. Oh god..."

Chara: "This feels much more intense than before."

Frisk: "It feels... like... it's eating us. Slurping us, and licking us as we are pulled into it's grasp."

Chara: "Frisk, the way you're describing this is making me feel really... really..."

Frisk: "Really what?"

Chara: "Frisky..."

Frisk: "Yes?"

Chara: "No, I mean it's making me 'feel' frisky..."

Frisk grabs Chara around her waist and pulls her towards her.

Frisk: "Is Frisky making you feel Frisky?"

Chara: "Oh god... Frisk... what are you..."

Frisk: "I'm feeling a bit frisky as well actually."

Chara: "Frisk wait... I don't..."

Frisk's and Chara's bodies touch. Chara is conflicted on how to feel about this. Frisk and Chara just started being friends after years of tormenting Frisk by possesing her, and now Frisk is showing a deeper level of affection towards Chara.

Chara: "Frisk... wait..."

Frisk: "Yes?"

Chara: "How can you forgive me... so easily..."

Frisk: "Look at you. You don't have evil intentions anymore and I believe you, don't I? And so I forgive you."

Chara: "I... you're right. I shouldn't keep hurting things for me."

Frisk put her right hand on Chara's cheek.

Frisk: "What about for us?"

Chara: "I... Frisk, your hands are still muddy."

Frisk: "So?"

Chara realises something.

Chara: "...I see now."

Frisk: "See what?"

Chara: "You... oh god!"

Frisk: "What... oh... ooh..."

However, before Chara can finish her thought, the mud has begun licking their groins. The feeling for both of them was extremely overwhelming as they descended ever so slowly.

Chara: "This feels too good..."

Frisk: "This... I didn't think it would feel like this..."

Chara: "I guess your glad... I didn't stop you... oh..."

Frisk: "Very..."

Frisk pulled Chara closer out of reflex and they felt each other's warm embrace in all parts of their body.

Chara: "Oh god... frisk... ughh..."

Frisk: "Sorry... I can't control myself..."

Chara: "Good... keep losing control... do more of what you just did..."

Frisk: "I... are you sure..."

Chara: "Frisk... please... I want to lose control with you... I want to be with you..."

Frisk: "I..."

Chara: "I want to get frisky... ughh... with you..."

Frisk couldn't find any other words to say. So she lost control and proceeded to kiss and writhe with Chara, which has allowed the mud to suck them deeper and deeper. They now both made contact with the mud above their underwear for the first time.

Frisk and Chara were humping each other, allowing the gooey mud to create more friction between their bodies and what's left of their clothing.

Chara: "Since when... did losing control... feel so good..."

Frisk: "Because this is... uuugh... how we want... to... ugh..."

Chara: "Frisk... can you talk like... like the mud is con... suming us..."

Frisk: "The mud has... already gotten us... It has claimed it's prize... and it wants to... savor us...

Chara: "Oh god... frisk..."

Frisk: "It wants to taste us..."

Chara: "It feels...

Frisk: "Lick... by... lick..."

Chara: "Ahhh..."

Chara could barely take it. Their pace has quickened overtime, and they have sunken up to their chest. Frisk and Chara were building up their fire and they were about to release it soon.

Frisk: "We taste good... we taste delightful to the mud..."

Chara: "Frisk..."

Frisk: "And we can... do nothing to stop... oh god!"

Frisk's underwear was slipped downward, and so was Chara's underwear. Their humps and thrusts caused their underwear to slip off of them.

Chara: "Oh my god... Frisk!"

Frisk: "We can... do nothing... to stop..."

Chara: "I don't want... to stop...!"

Frisk: "Take us, mud! Taste us... ahhhh!"

Chara: "Frisk...! Ahhh!"

Frisk and Chara could no longer hold the flame burning inside of them. They released the fire into each other, thrusting and humping uncontrollably.

Frisk: "AHHH! Chara! I love... you!"

Chara: "I... AHHHHH!... love you too... Frisky!"

The feeling of release is overwhelming them. They cannot stop and will not stop. They ride out what they think is the end of their session, but an end is not in sight. Their fire does not decline, it keeps burning hotter and hotter. Was it determination freaking out, or is it something to do with the mud? They were up to their shoulders and their underwear was no longer near them.

Chara: "Frisk!... I... can't... STOP!"

Frisk: "I... can't... stop... AHHH!... EITHER!"

Chara: "I CAN'T... TAKE... AHHHHH!"

Frisk: "AHHHHHH!"

Frisk and Chara felt like they were going to explode. The thick gooey mud, in fact, had a spell: It builds arousal to whoever is trapped inside, and it did not allow the arousal of the one trapped inside to decrease their arousal unless either of the two happen: 1. They escape. 2. They lose consciousness.

Who cast it? Who made it? No one yet knows.

Frisk and Chara were up to their neck. They could not control themselves. They could not care to. They could only scream in inescapable pleasure. Their humping was accelerating more and more.

They lock their legs even tighter.

They scream as loud as they can.

They are being swallowed by the thick, gooey jaw of the pit.

They have lost control.


EDIT: A couple corrections/modifications.

This was a great read! Will they escape though? Is there going to be a part 2? Or is this just supposed to have an implied ending? I want to read more!

Thank you, I'm glad you enjoyed it!

For now, I think it's best to say that it's an implied ending. I suppose I could make a part 2, but I don't think it'll there's too many details to add on, unless there was another force at hand.

By the way, I think I've read a couple of your stories recently. I remember enjoying them quite a bit, especially the heavy second person one for hypnosis. You're pretty good with writing. :>

Yeah, I agree that was a good writing. Only because it gave me an anime nosebleed from writing it. Like, probably have had under ten nosebleeds in my life at that time... probably less than 5.

But thank you for the compliment. I don't know where on this site I found something listing all these points as turn-on points, but in my stories, I make sure to hit all points on a sink, even if just 1-2 sentences. Those points are: Ankle, Knee, mid-thigh, upper thigh, crotch, waist, just below chest/bottom of rib cage, nipple deep, just over chest/armpits, shoulders, neck, head(titled back or looking forward), and submerged. I screenshotted someone that mentioned all those points. I don't know where the screenshot is, but their name was Viridian, at least on Deviantart, which is in their quote, and I have that post screenshotted just so when writing a story I can at least include each of those parts.

So that may be another reason my more recent writing is detailed. I hate when stories are like, "The character is knee deep. Now they are struggling to stay afloat using their breasts for buoyancy."

Another thing I do, if I'm thinking about it when writing, is make a point to mention bouyancy and include it in my story. Either something weighs them down, or in the story where they sank into lava, they reached buoyancy at crotch deep I believe, because if you could survive lava, you would only sink that deep.

Just some tips I use when writing. You can use them if you so wish.

I have decided to add a bit of a continuation to this story after all.

Because, why not?

Part 2:

They lost consciousness. They were no longer thrashing uncontrollably, for their bodies were too exhausted. The spell brought them into an extreme state of pure bliss, and it caused them to black out. The mud's mouth is still sucking on their necks.

A few minutes pass, and Chara wakes up first.

Chara: "Hnghhh... Frisk..."

Frisk was still unconscious. Chara had to wake her up, so they could get out. Their bodies were still intimately locked together. This caused a small spark of arousal in Chara, which would start to build up again if they did not escape. Once consciousness is regained, the spell can begin it's effects in a certain amount of time. For now, Chara's body is more relaxed.

Chara: "Frisk... Wake up. We need to get out..."

Frisk groaned a bit before she gasped slightly from her current contact with Chara's body.

Frisk: "Hey... Chara."

Chara: "We need to get out of this pit. Do you know how?"

Frisk: "I think so."

Frisk felt slightly groggy, but strangely only for a few seconds.

Frisk proceeded to free her arms from the mud successfully. She started to push the mud backwards from behind her to allow her to get out. It took a bit for to get a significant grip on the mud, but she managed to free her bare body above her waist. She then got leverage on the edge of the pit to push herself out the rest of the way. She was now out of the mud completely.

Chara was still neck-deep in the mud. The spell's effect were bound to be able to seep into them again shortly, if only a few seconds.

Frisk: "Okay... oh god! I'm completely naked!"

Chara: "Yea... we both are..."

Frisky: "Okay, can you free your arms?"

Chara: "Yea, pretty sure."

Chara pulls her arms out of the mud, which takes a bit of effort. Then she reaches for Frisk's hand as Frisk holds out her hand to reach Chara's hand. Immediately as their hands touch and Frisk starts to pull Chara out, Chara feels a tingling feeling all over her. Chara felt strange again.

Chara: "Oh gosh... this stuff really does feel good."

Chara felt the mud slide across her bare body as she was pulled out of the mud. As her waist was freed, she started to feel a flame burning inside her again.

Chara: "Ugh..."

Frisk: "You feeling good, Chara?"

Chara: "I do feel very good."

Frisk finally pulled Chara's foot out of the pit, but this led to Chara's body slipping right on top of Frisk. Chara immediately started aggresively kissing Frisk, and rubbing her body over Frisk's body with slow, but aggresive movements. Frisk was confused why Chara suddenly started acting like this again, but then Frisk started to feel a growing fire burning inside her again. As a result, Frisk decided to kiss Chara back, wrap her arms around Chara, and begin moving similarily to Chara's assaults. They have lost control again, but in a more safe location. The spell is no longer in effect, but the persistant feeling remains in them with a furious passion.

The mud allows them to easily rub each other's bodies against each other...

Faster...

Harder...

Their vocalizations were lost in their deep kiss.

They felt the pressure inside them build up as the fire in them was about to create an explosion.

The flame was burning hotter.

The pressure was pushing them closer.

They were about to explode with passion as they intensified the pressure of their thrusts and the fire of their friction.

Frisk held Chara in a death grip as they exploded onto each other with wave after wave of pure ecstacy.



After a bit, their bodies cooled down, and the flame was calmed again.

Frisk: "Oh god... Chara... What are we doing...?"

Chara: "Each other..."

Chara said with a smile. Frisk blushed.

Frisk: "I see you are learning from me quite a bit. But, Chara... are you okay with this...?"

Chara: "Okay with what?"

Frisk: "With what we're doing... it still feels way too weird to be doing stuff like this with each other..."

Chara: "I am more than okay with it. That was the best I have ever felt before. I mean it"

Frisk: "Really? I... It was the best I have felt... also..."

Chara smiled.

Frisk: "I'm sorry though... things probably wouldn't have escalated like that if I didn't join you in there. It just sounded too exciting the way you described how you felt in that soft mud, I wanted to see how it felt myself."

Chara: "I'm glad you joined me though, I would've felt lonely with myself in the mud had I known what the mud really felt like."

Frisk: "Really? You mean that?"

Chara: "You're so cheezy, of course I do!"

Frisk felt a little upset from the side comment.

Frisk: "I don't like being called cheezy..."

Chara: "Frisk... Not everything you say has to be super inspirational or well thought out. I'm just poking fun at you is all."

Frisk: "Yeah, your right."

Chara: "I'm sorry, I'll try not to call you cheezy, Frisky."

Frisk: "Heh, thanks."

A few seconds pass. Chara is still laying on Frisk.

Chara: "Hey Frisky, you know... I..."

Frisk: "Yea?"

Chara: "These past few days... of us hanging out and playing around... I... I... never had this much fun before... in a long time..."

Frisk: "I'm... glad. I wanted to have fun with you, and I have had so much fun being with you."

Chara: "Can we have fun like this... for... forever?"

Frisk: "I..."

Frisk was silent for a few seconds.

Chara: "I want to keep doing fun thing with you, I want to play more fun games with you, and... I want to... do you... more, especially in... this mud..."

Frisk was at a loss for words. She was blushing very hard.

Chara: "Frisky?"

Frisk: "Chara... I..."

Frisk was about to cry.

Frisk: "I didn't realise how much I wanted you to say that to me... until you did..."

Frisk's tears started to escape.

Frisk: "I... I want you to know... Chara..."

Chara: "Yes?"

Frisk: "I want you to know... I don't want you to beat yourself up anymore about anything you have done to me. I will always forgive you, and I will trust you forever. I... do... I also want to have fun with you... forever."

Chara was now failing at keeping her tears in. She lowered herself to kiss Frisk. Frisk melted into the kiss, and it escalated into a deep tounge fight.

Minutes pass by the intense thrashing showdown, and they seperate their mouths slowly.

Chara: "Wanna head back to the house and get a shower?"

Frisk: "Absolutely. I feel like we both need a really good cleaning after this."

Chara: "What about our clothes?"

Frisk: "Oh yea... shoot. If we take them now, they'll probably get more muddy."

Chara: "My pants got completely muddy."

Frisk: "You could probably put those on."

Chara: "Uhh... hmm. Nah!"

Frisk: "Heh, I guess we're going home nude then? Although, I don't want to get mud on our floor..."

Chara: "Ah shoot, that's another issue entirely..."

Frisk and Chara were in a bit of a predicament. Frisk was thinking of a plan that wasn't perfect, but it was better than nothing.

Frisk: "I'd say we take your clothes and wash them at home. We'll leave my clothes here and come back for them once we both wash ourselves."

Chara: "As long as you can find your way back here. Otherwise, you may have to stay nude for a while."

Chara spoke in a playful sedictive voice. Frisk blushed at the idea, but also didn't want to lose her clothes.

Frisk: "He heh... I don't want to lose my clothes quite yet though. I still like wearing them."

Chara: "Quite yet? When do you want to?"

Chara was still speaking in a playful tone.

Frisk: "You don't need to know yet."

Chara: "Alright, alright. I'll stop the act for now. Let's get going."

Finally managed to have a read through this... and it was brilliant.
