Septiplier/Antiseptiplier One-Shots

Trans!Anti (SMUT)

"Hey.. Dark, can I.. Tell you something?"
The small irishman asks his much larger boyfriend, and he looks up at him with a cute but slightly scared look.
"Of course, baby."
Dark wraps his arms around Anti's waist, kissing him on the cheek gently, Anti placing his hands on Dark's chest.
"You.. Probably will be upset with me.."
Anti says in a sad tone, but he stays strong.
"Baby, you know I never get upset with you. You can tell me anything."
Dark kisses Anti's neck gently, making Anti squeak a bit.
"Well.. I-It's something.. Extremely personal.."
Anti starts to trail off, Dark pulling away from his neck and looking at him, waiting patiently.
"I.. I-I'm.. I'm trans.."
Anti forces his words out, looking at Dark with his black eyes.
Dark sits there for a second, searching for something to say.
"Baby, that just makes me love you more."
Dark chuckles as he pulls Anti closer, making their hips touch.
"Wait.. R-Really?"
Anti looks at Dark with an excited look, his eyes starting to bubble and he starts to feel a little aroused for no reason.
"Yes, of course. I love you no matter what, sweetheart."
Dark kisses Anti gently, Anti immediately kissing back.
Their gentle kissing turns into a full-on makeout session as they move to the closest surface to lift Anti on, and they decide on the kitchen counter next to the fridge, Dark immediately shedding all his clothes off.
"Are you okay with this yet, baby?"
Dark tries to be careful with Anti, and Anti nods, moving Dark's hands to the bottom of his shirt.
Dark hesitates, but he takes Anti's shirt off, revealing a flat and unblemished chest.
Dark runs his hands down Anti's stomach, his beautiful form intoxicating him.
Then Anti does something Dark never thought he would do in front of him.
Anti moans softly, grinding his hips against Dark's obvious erection.
Anti was only in his boxers after a few minutes, and he looks at Dark nervously.
Dark places his hands on the hem of Anti's boxers, looking up at him.
"Anti, are you sure you want me to do this?"
Anti nods slowly, and Dark hesitates, but he starts taking off Anti's boxers.
Anti's face goes red as he sits there, completely naked and exposed in front of Dark.
Dark reassures him by running his hands along his curvy body.
"You're so.. Beautiful."
Anti moans softly as his curves were one of his most sensitive spots.
Dark pulls Anti into a gentle kiss, pulling him closer and closer until their chests touched.
"I'm gonna start prepping you now, okay? It might hurt a little."
Anti nods slowly, saying he understood.
Dark moves his hand down to Anti's entrance, slowly sticking a finger in, making Anti moan softly in response.
"You doing okay?"
Anti squeaks, and he nods, turning his head to the side, not used to the feeling.
Dark slowly starts going in and out with his middle finger, curling the tip of his finger up a bit.
Anti squeaks loudly, Dark kissing his cheek reassuringly.
"You're doing great, baby. Just 2 more."
Dark kisses his cheek again as he looks down to what he was doing.
Dark's eyes widen as he sees his finger completely drenched already, and he smiles, adding another finger slowly, using Anti's leakage as some sort of lube.
"D-Dark.. AaaAHh~"
Anti moans his words, Dark hitting a certain spot on the top of his entrance.
"Holy shit. I found it, I can make this so much better"
Dark starts to go a little more rough, gently slamming his fingers into that same spot, making Anti hum highly in approval.
"Is it okay to go faster?"
Dark says before gently placing kisses on Anti's ear.
Anti nods, Dark going a little faster, but not too fast because he doesn't want to hurt Anti.
"D-DaAarK.. Y-You can b-be RouGH with me.."
Anti moans highly as he feels something pool up in his stomach, something different than the usual feeling.
Dark hesitates, but he goes rough, slamming his fingers in and out, making Anti tremble underneath his touch and moan loudly.
A few minutes later, he has Anti writhing and screaming underneath him, his long fingers practically being shoved in and out of him.
Dark smiles, and he feels Anti tighten around his fingers, telling Dark he was close to dripping everywhere.
Dark adds another finger, making Anti practically turn into jelly.
Dark waits for Anti to adjust around his fingers and he goes as rough as he can, making Anti cry and drool.
"You're doing so good, baby."
Dark whispers seductively in Anti's ear, making Anti tremble underneath Dark.
Anti screams loudly as he feels as if he was going to cum, but instead a clear liquid starts to shoot out, it being a completely foreign feeling to him.
Dark starts to slow down his pace, his hand completely drenched at this point, and he takes his fingers out gently.
Anti pants heavily as he shivers violently.
"W-What.. W-Was that..?"
Dark moves down to Anti's ear and he whispers seductively.
"I made you squirt, Baby~"
Anti squeaks at the dirty sounding sentence, and Dark moves away from Anti's ear as he smiles.
"I've never been able to do that 'til now. You're the first that's been successful."
Dark gently rubs Anti's stomach to ease him down a bit, and he smiles from the work he did.
"T-That was.. I-It was weird but.. I-It felt.. Good."
Anti keeps shivering, and Dark chuckles a bit.
"I'm glad I could make you feel good."
Dark nuzzles Anti's cheek to try and help him calm down.
"You ready for the real thing now, baby?"
Dark whispers in Anti's ear, and Anti nods, Dark laughing seductively in Anti's ear, and he lines himself up with Anti's entrance.
"You sure..? I don't wanna hurt you.."
Anti nods, and he whimpers from waiting so long.
"Okay.. I'll try and be as gentle as I can."
Anti nods again, and Dark slowly starts pushing himself in, Anti moaning highly in response.
At about halfway, Anti starts to whimper in pain, and Dark stops.
"You doing okay, baby?"
Dark places a hand on Anti's cheek, his thumb gently rubbing underneath his eye.
"Y-Yeah.. I-I'm okay, Dark."
Dark kisses Anti's other cheek gently.
"Okay. Tell me when it hurts too much, okay?"
Anti nods, and he tries to adjust quickly.
"You're doing so good, baby. We're only halfway, so tell me when you're ready to go again."
Dark kisses Anti's forehead after he finishes his sentence.
"Okay, Dark."
After a few minutes, Anti gives Dark the okay, and Dark pushes himself all the way in slowly, making Anti moan from the size.
"H-Holy shit.. Y-You're so.. Long.."
Anti moans softly, making Dark giggle a little.
Dark lets Anti adjust as he showers him in kisses to the neck, cheek, forehead, and shoulders.
Anti gives the okay for Dark to start after a few minutes, and Dark slowly starts to go in and out, Anti moaning highly from how slow he was going.
"F-Faster, Dark.."
Dark goes slightly faster, grabbing onto Anti's hips gently for balance.
Anti squeaks as he feels better than ever, Dark coming down to gently kiss Anti, him kissing back just as gentle.
A few minutes later, Dark is going at a reasonable pace, Anti gripping at his back as Dark continues to thrust inside of him.
Dark hits the spot again, making Anti's moans take a slightly different tone.
"D-Dark.. AaaAH~"
Dark starts to slow his pace down until he stops completely.
Dark pulls out and he picks Anti up and off the counter, going back a bit and setting him on his feet before sitting on the floor, patting his lap for Anti to sit down on.
Anti gets on his lap, Dark raising Anti's hips up so he could enter again, and as soon as he starts pushing down, he's all the way in.
Anti huffs a bit, and Dark grabs ahold of his hips gently, raising his hips and dropping them, going in and out gently, making Anti moan softly from the sensation.
They continue to last a few more minutes until Dark has Anti screaming and writhing on top of him.
"D-Dark, AaaAh~! I-I'm g-gonna c-cUuUM~!"
Anti screams loudly as he feels the familiar sensation build up in his stomach.
Dark starts to violently thrust into Anti, making Anti tremble above him, Dark also close to orgasm.
Dark pulls Anti down to moan lowly in his ear, making Anti get a shot of pleasure.
Dark listens to Anti closely, his own orgasm extremely close.
Anti screams one last time as he cums extremely hard, Dark still thrusting up into Anti, being so on edge.
Dark eventually cums, groaning loudly as the liquid shoots up into Anti.
Anti squeaks at the feeling of being filled and he wipes his face.
Their activities drawing to a close, Anti pulls Dark up to kiss him, Dark immediately kissing back.
"God, I fucking love you so much, Anti."
"Of course you do, love."
THE END.
