🧠Summary: you're a hero, one who has struggled to remain good, but what happens when you're most guilty fantasy with your arch nemesis of all people, comes to light?

“Gotta go, duty calls,” You said as you leaned over in your bed and kissed San’s cheek.

“No,” San murmured, pulling you in tightly against his body, “Stay. They can send someone else.”

You gently extracted yourself from San’s grasp. “Nice try but I can’t be your pillow all night. Get some sleep, Baby.” San mumbled into his pillow as you left your shared bed with a fond smile on your face.

You and San had been friends since college; you'd both been training then to be supe's. The two of you had been brought together because of your powers. San had the ability to read minds and telekinesis, which was the makings of a villain. And you could shoot a heart with your finger and temporarily gain control of whoever you shot. Basically, your target would be in love with you and do anything for you. Which was also seen as the potential to be a villain. The two of you had banded together as outcasts and had been friends ever since.

Considering the reason you had become friends, you had made a pact with San: to never speak on your missions, because you didn't want your professional life to ruin your friendship. You didn't know what San’s alter ego was and he didn't know yours.

It had been only recently that your friendship had bloomed into a relationship. You were happy for it. San was the perfect soft and caring boyfriend. If only you didn't have a dirty secret that involved your arch nemesis.

Your comms told you your mission was at the old Treasure Hotel. Loudmouth was up to his old shenanigans. Apparently he had used his screaming powers and made everyone vacate the hotel so he could rob the safe. Except once you got there, running through the hotel, attempting to locate Loudmouth, you found no one. It wasn’t until you burst through the door to the rooftop that you discovered him--and his long-time ally, Killjoy.

“And I’m gone,” Loudmouth announced, jumping from the top of the roof, screeching when he presumably reached the ground to halt his ascent.

You narrowed your eyes down at Killjoy. The villain was your arch nemesis, the antithesis of your life. If there was a problem in your life, he was usually the center of it all. Of course you had to pull yourself out of bed from your boyfriend to confront the one man you didn’t want to see this evening.

“What’s this about, Killjoy?” You demanded. You summoned your power, folding one of your hands into the shape of a gun and using the other to support your wrist.

The masked villain smirked, folding his arms over his well-developed chest. “You can drop the act. I know.”

You continued to hold your stance. “If you know that I’ve plans for the mayor’s inaugural, that’s pretty smart of you. I didn’t think you had it in you,” you quipped.

Killjoy smirked. “I don’t need to be smart to know that you think of me when you stuff your pretty fingers inside of you.”

You dropped your stance immediately. “I have no idea what you’re talking about.”

“No?” Killjoy cocked his head. “You don’t think about me tucking my legs around yours to hold them in place as I ease in three fingers and you tell me you couldn't possibly take that much but your pussy takes them easily. You don’t think about me whispering how it’s so dirty that a hero could be taking my fingers so well. You don’t think about me slapping your pussy and pinching your clit and--”

“ENOUGH!” You shouted. Shame was covering you from head to toe right now. That was your exact fantasy, down to how many fingers you wanted him to shove into you. How could he suddenly read your mind when he’s barely skimmed the surface before?

Killjoy hopped onto one of the fans on the top of the building and leaned forward on his legs. His crooked smile pulled to the side, revealing a dimple. “Why just think about it when we could make it a reality?”

“Abso-fucking-luytely not!” You said in horror.

A hero? Getting finger banged by her arch nemesis? Never!

“How about this,” Killjoy suggested in a smug tone, “You show me what you do when you fantasize about me…” He took a moment to spit in his palm, “And I’ll show you what I do when I think of you.”

Your jaw just about hit the floor. “Excuse me?!”

Killjoy raised an eyebrow. “Don’t think it’s possible that I think about holding you down on my dick, shutting up that smart mouth of yours, always calling me a failure of a villain?” You clenched your legs together but Killjoy didn’t miss anything. “Come on, what’s a little mutual masturbation between old time enemies, huh?”

Your body worked on its own accord, your fingertips moving to the teensy-tiny skirt of your uniform. Killjoy’s eyes are glued to the pathway your fingers follow until you’ve raised the skirt and he can see your still clothed core but…

Killjoy’s tongue came out to wet his lips. “Is that a wet spot, Loveshot?”

You pushed your lips together and nodded. “Yeah,” You let out a shaky breath.

“Show me,” Killjoy insisted, leaning forward even further, eyes glued to your crotch.

You leaned back against the rough stone of the old building, fingers hovering over your outer lips. “I--you tease me a lot,” You admitted.

“Mhmm,” Killjoy prompted you.

“Sometimes you--” You gasped when you palmed your breast and found the nipple tight already. “--you pull and pinch my nipples and call me a superslut.”

You watched with bated breath as Killjoy peeled back the lower half of his suit and you sighed dreamily as his girthy dick was revealed. You knew there was a reason you used three fingers for him in your fantasies. “Now my turn. You usually say something about how my suit makes my dick look tiny, so when you protest, I rub my dick against your face and lips, but once my dick is seated in your hot mouth, you crumble and take it all for me.” Killjoy’s hips twitched upwards as his spit-covered hand moved up and down his dick.

"Sometimes I get so wet from pretending my fingers are yours that I--" You bit down on your lip to muffle a moan.

"Who's gonna hear you way up here Loveshot?" Killjoy smirked once again, "Let me hear all your desperate noises for me."

Shame still burns in the pit of your stomach. You shouldn't do this. You had San but everything was still new with him. This dirty little fantasy you've had of Killjoy had been around before you two had evolved from friends to lovers. You needed this.

You unceremoniously slapped your cunt and your head lolled back with how delicious it felt. "You tell me that I can take anything you give me, just like you know you can throw me into any situation as a hero and I can save the day."

Killjoy let out a low moan and scrunched his nose upwards. "I imagine your muffled noises as I push your face into my pelvis, making you take all of my dick. You choke and you cry and you say that you love every moment of it."

You're so worked up at this point that you could actually cum. "I'm--" You choked on the words when you watched Killjoy shamelessly spurt all over his hand.

He opened his eyes, heavy lidded with satisfaction and gave you a slow smile. "Come for me, my nemesis."

“Killjoy!” You come undone for him, pussy convulsing around your fingers and you ride them, closing your eyes for just a moment and picturing Killjoy’s smirk above you.

"Don't do that," Killjoy groaned.

You had forgotten he was still in your head. You ripped your fingers from your cunt and wiped them against your thighs to clean them. You turned to leave but Killjoy couldn't help but get a final verbal shot in.

"Where are you going, Loveshot? You're still thinking about me. You'll think about me later, won't you?"

You threw up a middle finger as a parting gift and shifted the color of your hair and your nose. By the time you made your way to the bottom of the skyscraper, you were completely indistinguishable from Loveshot. But you were still the same person. You had just gray-area cheated on San with your arch nemesis.

Your comms buzzed and you saw you received a text you simply could not ignore:

Sannie🥺: wanna meet up? I’ll order your regular at Blue Bird.

You: just finished up, see you there

Guilt wracked through your body. If you said no San would know something was up. But could you truly sip on a sugary sweet beverage, which your best-friend-turned-boyfriend had memorized as your order, as if nothing had happened?

You stumbled into the coffee shop that you and San frequented, only a few blocks away from your shared apartment. You weren’t used to fighting crime, then having a mind blowing orgasm afterwards. Your super power wasn’t stamina, that was for sure. Your eyes sought out San immediately, who waved you over to the table he was seated at.

“Hey Babe,” San greeted you.

“H-hey,” You replied shakily.

San had his normal gray hoodie but it was barely zipped up and you could see a sheen of sweat covering his upper chest that peeked past the zipper. He smiled softly, “I couldn't sleep, so I went to the gym. Sorry, I must smell like a locker room.”

You laughed under your breath. “You smell like you just walked out of a perfume ad.”

San scratched the back of his head. “Careful, I think my heart just beat a little harder from that.”

You smiled painfully. You attempted to sit at the café table and faltered, barely catching yourself against the edge. Unfortunately for you, your abused clit took most of the weight as you collapsed against it and you made an embarrassingly loud and desperate noise.

San’s eyes widened and then immediately avoided your eyes. What did he just realize?!

“San?” You worried your teeth on your bottom lip. You managed to properly sit down and sip your drink to do something, anything.

“Where did you just come from?” He asked quietly.

“Uh… you know, superhero stuff,” You shrugged.

The two of you had a strict policy of not speaking about your cases, to not muddy up each other’s professions. It just worked better that way. But San chose today to push it. He pushed up his glasses up the bridge of his nose and shifted closer to you. “Where did you come from?” he repeated firmly.

“The subway. Hostage situation. Wrapped it up pretty quickly,” You lied.

San sat back but eased an arm around the back of your chair. “Good.”

The tension eased out of your shoulders and you leaned into San’s embrace. “I’m tired. Let’s go home.”

The two of you walked home, San’s arm still around your shoulder, you still leaning against him. You were cold and were trying to absorb some of his warmth. Not even the drink from the coffee shop could warm up the sinking feeling in your chest. Even as you got home, got ready for bed, you couldn't shake your anxiety.

Guilt is gnawing at the end of your mind and you know that there is no going to sleep like this. You turned to tell San that you’re going to wind down in the living room when he approached you from behind. His lips are like sweet caresses along the slope of your shoulder. “Come back to bed with me,” he murmured, as if he could sense you were pulling away.

“Sannie,” You turned around in his embrace, “My mind--”

San’s eyes travel over your face, a hand cupping one side. “You’re vibrating with the need to leave. Let me put you to sleep.” Gently, San tilted your head with the same guiding hand, peppering kisses along your jawline.

Your heart soared and then crashed into your guilt. You couldn't possibly--not after what you did with Killjoy… “San, I’m really tired,” You protested.

“You’re not,” San disagreed with a rumble deep in his chest. “Even if your body may be, your mind is restless. I can help.”

San swept the straps of your pjs off your shoulders and continued to kiss down your neck to your collarbones. You can’t help but moan at the feel of his lips on your skin. Was your boyfriend seducing you?

"Where are you going, Loveshot? You're still thinking about me. You'll think about me later, won't you?"

Your body became tense with the sudden intrusion. Your powers brewed on the tip of your tongue and the pads of your fingers. You’d never use your powers against San but the need to push him off, to not mingle his touches with that of Killjoy’s was important!

“I have a better idea,” You found yourself suggesting before you could stop your treacherous tongue. “Let’s watch each other masturbate.”

San’s eyes widened considerably at your suggestion. “What?!”

Now it’s your turn to seduce. You ditched your top completely, to sit back on your shared bed and lie back, propping yourself up with your elbows. “Want you to watch me while I touch myself, Sannie,” You purred, “Wanna watch you while you touch yourself.”

San stumbled, as if his feet were moving him unbiddenly, but he made it to the edge of the bed where you were. You move so that the two of you are opposite of each other, a full view of whatever the other one’s planning on doing. You massage your breasts, making them pucker in the cool early morning air. San licked his lips like he wished they were wrapped around them. His eyes move to meet yours, waiting for you to start.

“Before we got together, when we were just friends, I used to get off to the idea of you sneaking in my bed and eating me out,” You said shakily. “I would play with my nipples and put so much lube on my pussy, using one of those flower vibrators, wishing it was your tongue. I had convinced myself that you loved eating pussy and it was something I wanted you to want with me.”

San groaned and began to palm himself through his sleep pants. “We were idiots.”

You couldn't help but giggle. “We were.”

San watched with rapt attention as you pulled aside your underwear and dipped a finger into your wetness. You spread it along your clit, moving in slow, tantalizing circles, careful of how abused your clit had been just a few hours ago by your own self torture. “Sannie?” You prompted him.

San snapped out of his deep thought while watching your finger circle your clit and pulled himself out of his confines. “I used to want you to use your power on me.” His voice cracked and he had to clear it. “Make me do whatever you want me to do. I used to edge myself for hours alone on the thought that you’d never let me cum unless it was inside of you--pussy or mouth.” San’s blunt fingernails dug into his thighs but he didn’t touch himself.

You stop touching yourself and crawled towards San’s body. “Do you need some lubrication?”

San whimpered as you hovered over him, hands on either side of his hips. You spit on his cock, letting it slowly dribble downwards. You leaned downwards, almost as if you were going to take him in your mouth but instead you simply blew air on him. San’s hips thrust into the air, whining again. “Please,” he asked but you weren’t sure he even knew what he was asking for.

“Go ahead and touch yourself,” You encouraged him.

“ ‘m sensitive,” San mumbled, eyelashes fluttering against his cheekbones as he blinked many times, a cute pout pulling at his lips.

You can’t help but grin at the admission. “Did you masturbate while I was out, Sannie?”

San’s body jerked backwards, a loud gasp in the back of his throat. “N-no.”

You dropped your body so that you could take San’s cock in your mouth with one quick dip of your mouth. San’s body strains at being encompassed suddenly by your warm, wet mouth. Tiny thrusts into your mouth tell you all San wants is to get off in your mouth and by the throb of your lower half, all you want is to give it to him.

"I imagine your muffled noises as I push your face into my pelvis, making you take all of my dick.

How is it that you're sucking off your sweet boyfriend and you can't get Killjoy's degrading voice out of your head?

At that exact same moment, San's hands grab both sides of your head and he began to fuck your mouth. You have no time to think, only time to make sure your breaths time with the in-and-out motion of his cock down your throat. Your nose practically buries itself into San's bronze skin, mouth coming flush with the base of his cock. San had never--

Just as quickly as he held you down on him, he pulled you off of him. You stare up at him, saliva and precum dripping from your open, panting lips. “San?”

San adjusted immediately, a dopey sweet smile pulling at his lips, making his eyes become crescent moons. “I don't want to cum in your mouth.”

You're fast to climb onto his lap, arms draped over his broad shoulders. “My baby,” You couldn't help but coo, “You really do put me first, don't you?”

San smiled shyly, scratching the back of his head. “I love you, that's why.”

Your heart burst at the admission. “I love you too, sweet boy.”

The two of you moved your hips in sync, exchanging kisses and moans, as you made love in your shared bed. This was where you wanted to be: in San's arms, drinking in his noises of pleasure, being the center of his world. You didn't want to be with--

Your climax hit you like a slow burn and the first thing that tumbled from your mouth was the name you had been thinking of. “Killjoy!” you groaned quietly.

San’s body was ramrod straight even though you could feel his dick twitching inside of you, his cry cut off at what you said. You scrambled to remove yourself from his body but San wrapped his arms around you to keep you firmly in place.

“What did you just say?” San said in a voice that broke your heart into a million pieces.

“No-nothing,” You stuttered, throat full of emotions.

“Where did you go when they called you out,” San demanded again, bringing up his question from earlier.

“I told you, the subway--!” You squealed as your back hit the bed, San pinning you down with his heavy body against yours.

San reached for your hand and squeezed it tightly, intertwining your fingers with his . “You have two seconds to answer me correctly before I read your mind, love.”

“San!” You gasped and visibly reeled back. San never invaded the minds of the ones he loved, he swore he would never.

San licked his lips, a frown furrowing his eyebrows. “I’m not asking casually.”

Your gut was telling you that suddenly your entire world depended on the answer to this question and you had no idea where it would land you. “I was on the rooftop of The Treasure Hotel.”

San cursed lowly. “Loveshot?”

Your heart was beating a mile a minute. Had San just guessed your alter ego? What did that mean?

San let go of your hand and shakingly raised it to his face. You thought he was going to rub it tiredly over his face, somehow privy to you cheating on him with your arch nemesis. “Sannie, please, it was nothing!” You cried out.

Instead, he covered his eyes and smirked. “I already know.”

Your blood chilled in your veins.

The masked villain smirked, folding his arms over his well-developed chest. “You can drop the act. I know.”

“Killjoy?” You yelled in disbelief.

And, you swear to God, San's dick pulsed inside of you upon hearing his alter ego's name upon your lips in your shared bed.

“No,” You shook your head. There was no fucking way your best friend, your boyfriend, was an evil villain?

Flashbacks to the supe's college you both attended, the way you were both outcasts, vaguely bringing up your powers as the reason. Bonding over wanting to overcome your natural abilities and prove to everyone you were good.

“Someday, the world won’t judge me,” San had proclaimed. Clearly that had not crossed over very well.

It all came crumbling down around you.

San lowered his hand and there was a glint in his eye. “If I had known…”

In some fucked up way, relief flooded you. You hadn't cheated on San; you simply masturbated with his alter ego. That was okay… right?

“Are we…” How were you going to meld the two worlds together, how could you continue to date and fuck a villain, how-- “Are we okay?”

San’s lips surged towards yours in a kiss that was desperate and messy and yet somehow full of love and adoration. “Do you still love me?” San gasped into your mouth.

You looked up at the man who was your everything. Even now, knowing he was your arch nemesis and had been for a long time, he was even more so your everything. He was your world when you weren’t working and he was your obsession when you were. Was this going to fuck up your job? Absolutely. Was it going to fuck up your relationship?

“I love you like the sun loves the moon,” You admitted. Surely the two bodies in the sky were enemies, constantly chasing after each other, constantly fighting for time in the sky.

A subtle shift of San’s hips had you gasping. He was hard inside of you. His eyes were alight with love and mischief and lust. “I love you like a villain loves a hero.”

And that was the end of that conversation.
