This is an Au Undertale fanfic. All the characters in this are female. M rated, may have lemon later on.

Main character is called Cherry Red. Let's begin:


I groaned awake after what seemed like one of the strangest nights I've ever had. I had a dream that I was in a version of Undertale... but in this universe, everyone was a female and they were wanting to fuck Frisk because all of them were horny... but then why did I feel... not in my bed?

I then shook my head awake and tried to get out of the sleepies in my eyes, me then seeing that the area around me was... purple and dark? And I was laying on top of... BUTTERCUPS?!

"WHOA SHIT!" I shouted as I then finally woke up the whole way and looked around... was this for real? Was I really here?! Where was my pink room?! My video game collection?!... MY MOMMA!

"Ugh, what's up with her?" I heard a female voice ask, me looking to where it was... and then gasping and jumping again, which made the girl look at me in annoyance. "Great, now she's insane," she said.

"I-I'm not insane! I-I can see through you part-way!" I said, her then gawking at me after. Why? It was CHARA!... But why did she have a bigger chest... and looked to be a teenager? Maybe?

"Wait... you can actually see me?... Tell me, what's your name?" she asked.

"C-Cherry Red... a-and who are you?"

"Charlotte Dreemurr. My nickname is Chara... why are you looking at my chest?" she asked, me then immediately darting my eyes to her eyes in response.

"S-Sorry... um... question... d-do you know anything about... um... video games?" I asked. I felt I could be safe telling her, since she seemed nice enough, not at all evil... sure, the red eyes were concerning, but she looked normal aside from being a spirit.

"What. The fuck. Are video games? I was born in the 1800s. Please explain further," she frowned.

"Wait, really?... Uh, ahem... w-well... it seems that I've been sent from my own universe... into a video game universe? And you were one of the main characters in it?" I asked, Chara frowning at me.

"That's the dumbest thing I've ever heard. Fine, tell me what you know," she frowned.

"Um, well, you originally jumped down here for an 'unhappy reason' and then were rescued by Prince Asriel... then, you were basically the hope of the Underground. And you had the idea to save everyone by getting the barrier destroyed, so you gave your soul to Asriel and you went to the surface to grab 6 more to destroy it... then, the villagers attacked him and then-" I was about to finish before Chara stopped me.

"Stop, stop. There are a few holes in your story. First off, it's not a prince, she's a princess. Her name is Angela, not Asriel. And I jumped down here to escape angry natives after they killed my parents... but everything else is so far correct," she said, me gulping at that...

"U-Um... that must mean this is one of the alternate universes... or Underverse... tell me, what's the deal with the monsters?" I asked.

"Every monster is a female and they hate human females... mainly because the human females were the ones that trapped them down here. And the main reason is because the human females hated them for being preferred by the male humans. They were sealed in this mountain in the 1400s, it being part 2 of the reasons we came to America. To seal the female monsters underground a mountain chain," she explained.

"I uh... I see..." (oh my, I didn't know I was sent to a different Undertale reality!... Does this mean it was kinda like my dream?) I immediately checked myself and saw that I was still completely normal... including the part on me that made me unique.

"Whoa! W-What the fuck is that?!" Chara asked when she saw it.

"Um... it's my uniqueness?... I'm a hermaphrodite," I said. And that was the truth. I had both female and male anatomy, including the parts for both of them. It was very odd, but I had to be careful not to let too many know in my world, because it was very embarrassing. And anyone who did find out thought of me as a monster... or, more of a monster than the ones in this place.

"I uh... I never knew such a thing existed... how many in your world have this?" Chara asked.

"Um... very little. Most of the time, people who have this status have a lot of health issues, as it's a birth defect. But I was lucky to have the perfect genes for this... ahem... we should probably keep going," I said, her nodding as I then walked forward and, when I did, she gawked as, when I got a bit too far, she then was yanked forward for some reason.

"ACK! Y-You're pulling me?!... You have a Determination soul, don't you?!" she asked, me shrugging my shoulders. "Whaddaya mean you don't-" she was about to finish before we then found the first character of the game.

"Howdy! How're ya doin', pal?" Flowey asked.

"Doing okay, just so massively confused," I admitted.

"I'm Butters!" (Wait, what?) "Butters the Buttercup!" (You've gotta be fricking kidding me) "Well, since your new, someone's gotta teach ya how things work down here," SHE spoke, me then gulping at how her voice sounded... cute? But then, she gained her evil grin face. "See, down here, we HATE you human girls! And I need something you have. Give it to me, or I'm going to keep you as a torture toy forever and ever," she said angrily, me frowning at her.

"Apologies, but I'm not into that shit. I prefer being in a healthy relationship, not S and M dungeons," I frowned.

"What? What's S and M? Make sense and give me your soul!" Flowey... Butters said.

"No," I frowned.

"What. What did you just say?" she frowned.

"I need my soul to live. So, no. And if you don't like it, little brat, then I'm going to tell you this. I. Know. Your. Secret," I said, that immediately making her get a wicked grin.

"Really? Then I have no qualms in doing this, then," she smirked as I was then surrounded by petals on all sides, each one having thorns on them.

"What are you doing?! Get out of the way!" Chara shouted as she ran for me and took out all of the petals in her ghostly form, which confused Butters for long enough for a fireball to be sent at her, which sent her right to the wall and for her to escape underground shortly after.

"What a miserable creature. Torturing such a poor innocent... wait..." said the voice of Toriel as I looked at her... and gawked. She looked... so hot! She had a much bigger bust than in the game and she looked super sexy, even when looking realistic! "A human female?... Leave, you don't-" she was about to say... but me seeing her boobs jiggle made my member get stiff. And she definitely noticed. "OH MY! W-What?!" she gawked as she then looked at it and I then put my hands over it... mainly because it was a good 6 inches long, as much as I loved it, it made it hard to hide when it got stiff.

"S-S-Sorry... I-I saw you... i-it's automatic, I didn't mean to-" I was about to finish before Toriel spoke.

"Tell me, who are you? A male? Or a female?" she asked.

"U-Um... both?" I said, her looking at me in annoyance. "I have both parts, I mean... I have the chest and vagina, but I also have a dick... I prefer going by she, but... I-I'm sorry... why are you asking me this? Is there a reason as to why that flower said that human females are hated down here?" I asked, Toriel frowning at me.

"You mean you don't know?" she asked.

"Miss, the only thing that I know so far is that I was suddenly teleported here from another reality, that I'm joined by a ghost of some girl that only I can see, and I now know that the monsters down here are going to hate me for being a girl, dick or no dick," I frowned.

"I see... so... you aren't mad at me?" she asked.

"I'm just immeasurably confused... and I need to know more before I can form a plan... I've been told by this ghost that the monsters down here are all female, but then that flower, called Butters, said that everyone hates girl humans... can I please ask for you to explain it?" I asked, her sighing at that.

"On one condition. Who is this ghost that you're speaking about?" she asked, me gawking as I then looked at Chara and she gave me a glare.

"Nice one, now I hate you," she frowned.

"Um... oh god, can I tell her or not?" I asked Chara.

"She's not going to budge otherwise. She's very stubborn. Stubborn as a goat," she said, me smirking at the bad joke before then sighing.

"Her name is... Charlotte. Nickname Chara," I said, her then gasping and then doing something different. She SLAPPED me on my face!

"You lie! Don't speak of her name again!" she growled at me.

"Ow... tss.. it's the truth, though... she said she fell down here in the 1800s to escape angry natives, that she was viewed as the hope of the Underground, and that she was best friends with the princess," I said, Toriel frowning at me before then speaking something.

"If it really is her, then ask her something only she knows. What is her favorite brand of chocolate?" Toriel frowned.

"My favorite brand of chocolate bars were Cailler chocolate bars. White chocolate version was my favorite," Chara said.

"She just said her favorite brand was Cailler chocolate, white chocolate especially," I said. And Toriel gasped before sighing.

"I see... I... I'm sorry for slapping you, then... it's a touchy subject... you say she's here with us, then?" Toriel asked. I nodded. "Can I tell her... how sorry I am? I didn't want any of this to happen in the first place," Toriel sighed.

"No, I should be the one to apologize... I was the reason for everything... with my stupid plan to work together with Angela," Chara sighed.

"She said she's the one who should be sorry... she was the one at fault. Because of a plan involving Angela, buttercups, and passing through the barrier," I said, Chara then slapping me on my other cheek, me gasping as I could actually feel it! "OOOW! You've got quite a backhand for a ghost!" I snapped at her.

"Y-You actually FELT that?! HOW?! I'm a spirit!" Chara shouted at me.

"We should probably keep going before that miserable flower shows up again... we'll speak on the way," Toriel said as we then followed after and I then had to rub my hand against my cheek, as I felt very sore from Chara's and Toriel's slaps.

"Yep, both of 'em are gonna bruise... you ladies don't hold back," I groaned. And then, I saw a save point, a twinkle by the staircase that led to the Ruins.

"Use that save point and you'll heal. After all, you have Determination," Chara said, me then doing so and feeling the pain go away!

"So... may I ask how you arrived here in the Underground?" Toriel asked me as she solved the first puzzle to open the door.

"It's uh, complicated... I fell asleep at my actual house... and then, when I wake up from a wet dream, I'm on a bed of flowers outside of the room that we first met," I explained.

"I see... that's very weird. So you say you come from another universe?" she asked.

"Pretty much. And it's so bizarre being in a world where I can see ghosts, talking plants, and a goat woman that has uh... um..." I said, Chara then putting a fist in my face.

"Don't you fucking dare, bitch. That's my mom," she frowned at me.

"Are you saying that I turned you on?" Toriel asked, me blushing at that and for her to giggle. "Sorry, couldn't resist. But so you know, I'm not ready for it yet... I'm still upset at the whole ordeal that involved my daughter..." she admitted, me sighing at that.

"And I can respect that. I'd never be caught trying to force anyone into doing that... just know that I think you look super-hot," I admitted, Chara then getting ready to punch me before Toriel laughed.

"And I can assume that little Charlotte is getting upset, isn't she? Haha!" she laughed, Chara frowning at that.

"Hmph, don't make anymore comments like that, or you're getting more than punched. Don't repeat that," she frowned at me.

"Got it, that," I said, Chara frowning before I then spoke some more. "That, that, that, that," and then I had to dodge a punch from her and then grabbed her on the arm and got her in a headlock.

"ACK! Cut it out! Uncle! Uncle!" she shouted.

"No punching me and I'll let go, okay?"

"OKAY! I promise I won't punch you at all! Let me go!" Chara shouted, me smirking and doing so, but me then slamming her into the ground and her groaning after. "Dammit... how are you so strong?" she groaned.

"Boy genes and girl genes. That's your explanation," I smiled at her.

"Were you just fighting with her?" Toriel asked.

"Yeah, she tried to punch me for annoying her, so I got her to agree not to punch me again, then I slammed her into the ground," I smirked.

"Heh, you're strong, too. Regardless, we should keep going," Toriel said as we then found the Dummy and I saw that... it was a training dummy with boobs.

"Of course," I frowned, but I said it to myself with just a breath of a whisper.

"Here in the Underground, many monsters will wish to harm you or worse, as you are a female... but you can find something to make sure that they don't attack you. Try talking to this dummy," she said, me going to the dummy and her looking at me in confusion, though she didn't move at all.

"Uh... hi... how are you doing today?" I asked, the ghost in the doll looking concerned as I sighed. "I'm not dangerous, I promise... in fact, I feel that I'm the one in danger right now." The dummy then sighed as she then floated over to me and poked me with her lower half, just to test the waters, I guess.

"You're... not attacking me?... Why?" she asked.

"I'm not a violent person. That's your reason. The only reason I would fight is if it were in self-defense, and never with the intent to harm, just disarm," I smiled.

"I see... that makes y-you different than the others... during the... the incident..." she said before then returning back to the station, her smiling at me. "Thanks... wait... what's in your pants?" she asked, me sighing. Of all times for me to be turned on, why did it have to be from a doll?

"Uh... it's something that only I have... I'm a girl with a penis," I said, that making the dummy smile and to come close to me again.

"You got turned on from my big tits? You can always touch them if you want," she said, me smiling and blushing as I then did so and the dummy giggled at the feeling, me being so confused before I then stopped after 10 seconds of groping.

"Thanks... they felt nice and rubbery," I smiled at her.

"Heehee, thanks," the dummy giggled as Chara then went to my side and spoke to me.

"You're into girls? Seriously?... I guess it makes sense, since you could always be able to make kids with that appendage," Chara spoke.

"Who knows? Maybe it'd work with you as well," the dummy said, me then looking at it and then at Chara.

"Wait! You can see me too?!"

"Ghosts can see other ghosts. If I were completely merged with my vessel, I'd be unable to see you. But I'm still getting used to it," the dummy smiled at her.

"Huh... so two people can see me. Greeeaaat..." Chara frowned.

"Question, CD... is it possible for-" I was about to ask an important question before she spoke up.

"CD? Really? Why not call me by name?" she asked in annoyance.

"In case a certain weed overhears us," I said back.

"O-Oh... right, that makes sense," she said as we then moved to the next room and followed Toriel into it, us coming across a Froggit, me seeing it looked just like in the game, just with a visible chest on her and looking... adorable? And in real life, it looked like a kappa girl instead of being a frog with four eyes.

"Who are you?... And why do you have boobs and a... thing?" the Froggit asked, me smiling at her.

"I'm a hermaphrodite, meaning I have both parts. And I'm nice... by the way, you look adorable," I smiled.

"Oh... ribbit... thanks," she said before hopping away.

"Flirting too? You are weird... anyways, the question?" Chara asked as Toriel led us through the spike maze.

"I wanted to ask if it'd be possible for you to... be alive again?" I asked, Chara gasping before then hammering her fingers together.

"I... I don't know... I mean, my soul went to the other side... a-and I still don't know how I'm able to be here next to you, but it seems I'm able to feel things when close to you, despite not having a soul... if it's possible in the future, yes, I'd love to be able to be alive again. But how would we be able to do so?" Chara asked.

"Well, maybe since that ghost was in a dummy, maybe we can find something for you to inhabit?" I smirked.

"Huh... you know, that isn't the worst idea I've ever heard. But if I'm inhabiting something, I want to be the one to choose what I go inside of. And it has to be human-like, not a doll and it has to be the same size I was or slightly bigger," Chara said, me smirking at her.

"Really? Slightly bigger, huh? Do I hear a hint of jealousy?" I smirked as she then frowned at me.

"Yes, very much so. I was 20 when I died and I still have a B cup at the least... you have DDs! And a huge penis!" she complained. And then, we reached the area that was a long hallway, Toriel then smirking at us.

"I need to go ahead in order to prepare a meal for you. I have a feeling you can befriend the monsters along the way. Here, just in case, I'll give you a spare cellphone. It only does calls, but my number is in there. Be careful, okay, deary?" she smiled at me.

"Gotcha. See you in a bit, Tori," I smiled, her nodding as she then went off ahead and Chara then looked at me with a frown.

"Are you wanting to get in her pants or something?" she asked.

"No, I'm not," I said.

"Then why the constant flirting?"

"I flirt with everyone, just depends on how they treat me. I'm not going to try and force myself onto others, especially someone that tells me they're not ready," I explained.

"I see... but be honest. Do you view her as a potential suitor, should she say yes?"

"Yes, same with you," I smirked, Chara blushing after before then sighing. "And when I get you a new body, I'm going to try my hardest to help you out. But until that happens, your name is CD, just in case that flower shows up again. Because, fair warning, she's uh... she'd want me dead even more if she found out you were with me," I admitted.

"Wait, really? Why?" she asked.

"Because... tss... you were her sibling," I said. And then, when I did, she then grabbed me after.

"What?! You're lying! You have to be! Angela can't be that flower! She'd never want to kill someone, girl or not!" Chara shouted.

"She has no soul, no emotion, and thus, has no ability to feel anything. She only views me as a means to an end. If she gets my soul, she'll try to become a goddess by grabbing the other souls that have been captured," I explained.

"W-Why, though? Why would she do that?"

"I can't really explain too much, but let's just say that being unable to feel anything makes someone desperate to try anything to do so. Including murder... and she's killed before to try and feel something, and she could do so again if she felt like it... but with my soul down here, she's unable to do much. So I need to stay alive, lest she try and steal my soul and do much worse... but I promise you, I'll try to save her as well," I said with a smile.

"You promise?"

"Cross my heart."

"Okay... you better not be pulling my leg, or I'm going to make you suffer my hauntings forever," Chara pouted at me.

"Yeah, right... especially considering that, in another timeline, you were much more dangerous," I frowned.

"Explain."

"There were three timelines of this adventure where I came from. Pacifist, neutral, and genocide... and in the genocide run, everyone dies at the hands of the main character. And at the end, you make them pay by erasing the world with an LV of 20... and if they don't want to do so?... The face you make still haunts me to this day," I admitted.

"What face was this?"

"Giant black eyes bleeding black blood, mouth just as black and bloody, laughing like a maniac and rushing forwards in an erratic fashion with horrid music backing it up... you looked like this," I said as I then drew into the dirt with a stick and showed the pixel art with Chara's jump-scare face, her then gawking at it.

"Y-Yeah... creepy," she admitted as I then dusted the picture away and instead made a picture of a butterfly instead. "Better, I like butterflies," she pouted.

"Just in case a certain buttercup sees the art," I smiled at her as we then moved down the road once again. We needed to get to Toriel's place... I hated to admit it, but I was getting quite hungry.
