Blue peered around the corner spotting his alternate self on the couch. 

 He wasn't sleeping for once he noted dimly sock clad feet rocking to tune only he could hear. Perfect he could finally tell him his true feelings! Blue fought back giddy laughter his magic stirred in his bones with his rising excitement. He had to take a few deep breaths to calm himself. If he just jetted over all bubbling and babble his words would come out jumbled together and it was the last thing he needed.

Blue wanted to make his great affection known clearly. Acting as his usual hyper self would just amuse Sans and the other skeleton would egg him on and somehow they would end up cuddling on the couch and that would lead to them sleeping. Not what he wanted. Even if the cuddling was nice. Sans like using him as a pillow being relatively the same height it made snuggling easier. Blue could wrap his arms around Sans hugging him close as he sighed nuzzling his clavicle breath puffing close to his . . .

Warm magic flooded his face pooling in his cheekbones. Really he shouldn't be thinking such things before even confessing! He shook his skull now trying to calm his rolling magic.

Blue realized he needed to move quickly, Sans’ feet went still he was more than likely seconds away from sleeping. I CAN DO THIS! He thought walking forward determined. Alphys always told him never to hesitate when he wanted something. And he definitely wanted his alternate self. Blue strode to the couch dropping on it. His other self cracked an eyesocket open. “hey Blue sup.”

“SANS I-” Blue paused cheeks puffing out in a pout. Didn't he just tell himself to control his excitement? That meant not yelling if he was going to be honest. Sans always took what his Papyrus and he said seriously when they didn't speak with their usual volume. “I I wish to confess something.” Blue tried again regulating his voice.

“i’m listening.” Sans’ other eye opened so he was given his undivided attention. A sudden bout of nervousness clawed at his soul and Blue ended up blurting the words out.

“I I LIKE YOU!” He squeaked loudly and wanted to bury his face into the couch’s pillow. So much for not yelling.

Sans blinked at him then chuckled his grin softening into a smile. “aw Blue i like you too,” Elation filled his being then left just as quickly when Sans spoke on. “i think you’re a great friend.”

NOOO NOT IN THAT WAY. He thought panicked. He needed to be more clear. “Sans I Like You Like You!” The other skeleton sat up blinking slowly.

“like me like me? Blue are you . . .” Sans sounded confused which wasn't what Blue was going for. He needed to be clearer. Once again Blue blurted the first thing that came to mind.

“I Want To Have Sex With You!” His face exploded with heat as magic flooded it swiftly. Blue groaned mortified now burying his face in the couch's pillow. That did not go as planned . . .

Sans’ eyelights blew wide at the confession magic filling his cheeks with his surprise. “oh like me like me. okay i uh see now.” He scratched his cheekbone uttering a slightly choked laugh. “heh heh you don't beat around the bush when you want something huh?”

Blue whimpered. “I’M SORRY. I SHOULDN'T HAVE SAID THAT LAST THING.”

“nah there’s nothing wrong with being honest with what you want.” Sans said shrugging. Blue peeked at him blue eyelights quivering.

“Then do you like me?” He asked quiet.

“ah well,” The lights of Sans’ eyes darted off to the side. The blue tint on his cheeks growing darker. “i like you.”

Blue pulled away from the pillow. “Like me more than a friend?”

“mm-hm yeah more than that.” His flush grew even darker.

“Then,” Blue’s gaze was unwavering staring at him, Sans fought back a shiver at the intensity. “Would you let me have sex with you?”

“i i wouldn't mind if you did.” Sans stuttered and felt like hiding from the glint that appeared in Blue’s bright eyelights.

“Even if I topped?” Blue asked lightly no longer nervous he shifted bringing his legs onto the couch turning towards him.

“ah it’s probably best if you did. y’know how i like taking it easy.”

“Mweh you would be lazy even while having sex.” Blue huffed sounding amused smiling.

“heh you got enough energy for the both of us so why not let you do everything.” Sans grinned cheeky.

Blue crawled across the couch pressing close to Sans their faces inches from each other. “Then I’ll make sure to pleasure you thoroughly!” With that declaration Blue leaned forward kissing his other self. There was a spark of magic between them they both shuddered conjured tongues sliding out twinning together.  

This was better than he expected. Blue thought dizzily pushing forward Sans fell back on the couch allowing Blue to settle onto his hips deepening the kiss his tongue slid into his other self mouth curling. Sans moaned under him arching the sound rattled between them from his ribcage. Blue’s magic whirled and rolled with his rising excitement. He could scarcely believe this was happening. He could feel Sans’ magic lazily cresting responding to his own.

Blue was sure he was going to burst from happiness. His soul fluttered with his emotions. This was way better than the fantasies he had whenever Sans crossed his mind. To be this close to his alternate self was a dream come true! He wanted to explore Sans’ body, to find every spot that would bring him the most pleasure, to hear all the sounds he would make!

Blue broke the kiss pulling back to look down at him. Sans’ blush was deep blue spread over his cheekbones white eyelights hazy breathless from the kiss. He looked so soft~. Blue’s mind blanked from the sudden rush of affection that flowed through his being. He wanted to hug his other self and never let go.

“hey,” Sans’ hands came up cupping his face catching his attention. “maybe we should take this up stairs? wouldn’t want to give our bros a show.”

“Oh,” Blue hummed blinking. “You have a point.” Getting caught in the middle of that would be highly embarrassing. “And doing something like this on the couch would make a mess.”

“heh,” Sans chuckled wrapping an arm around his waist. They promptly fell through a shortcut.

Smooth phalanges caressed the inside of his quivering thighs with light almost teasing touches trailing to the mound between them. “OH,” Blue giggled breathless and amazed. “You’re dripping~.” He sang a phalanx just brushing the outer lips of his shimmering pussy. Sans sucked in sharply hips twitching forward trying to increase the pressure. Blue’s finger dipped between his lips just touching his clit making him arch. The spike of pleasure made his head spin.

“Fuck!”

“No cursing,” Blue said then paused and smiled chirping. “Well maybe this time around you can.” He parted Sans’ lips sliding a phalanx into his entrance with a wet sound. Sans’ walls clamped around his finger squeezing as he cried out. Blue shivered pleasure curling in his soul. His formed magic twitched between his thighs. His alternate self felt wonderful around his finger, so warm and wet.

And getting wetter as he began thrusting his phalanx. Sans’ magic dripped on the bedsheets over his digits. Sans breaths came out ragged as he writhed hips rocking up meeting Blue’s thrusts the walls of his conjured magic fluttering. Blue stared enthralled eyelights bright, the sound of his finger moving in Sans and his breathless gasps echoing in his skull. He slipped another phalanx in curling. Sans uttered a low keen thighs squeezing together.

“Blu-Blue!”

“Yes Sans?” He cupped his other self’s thigh with his free hand parting them speeding up his thrusts shifting closer. Blue could see his fingers working Sans open through his magic.

“i i-!” Sans moaned skull lolling on the pillow. Every part of him was shuddering.

“About to come? Oh please do! I want to see when you do!” Blue burbled with excitement moving closer now situated between his legs. He brought his other hand down rubbing Sans clit in quick circles.

Sans screamed body quaking magic gushing around Blue’s fingers buried inside him. The other skeleton made a pleased sound feeling Sans’s walls quiver as he pulled out. Dark blue magic dripped off his phalanges. A thrill went through his being, a jolt of heat in his soul. To reduce Sans to a trembling flushed panting mess made him feel accomplished. His magic throbbed, arousal rolled through his bones. Blue shifted forward rubbing his member against Sans’ soaked lips making him whimper and twitch.

“Blue . . .”

“Sorry,” Blue panted staring down at himself nestled between Sans’ trembling magic. “I I know you’re really sensitive right now but I I don’t think I can wait any longer. Please can I . . . ?”

“Haa . . .” Sans breathed out bliss still thrumming through bones. Blue eyed him blue eyelights hazy vaguely shaped like hearts a soft dusting of pale cyan on his cheekbones. He was shaking pressed against him, cock twitching in his folds. Sans swallowed. “yeah go ahead. not too fast though.” With how sensitive he was after coming he couldn't handle anything too rough or quick.

The other skeleton beamed. “YES OF COURSE I’LL BE VERY GENTLE.” Blue swooped down pressing their teeth together. Sans mewled into the kiss shivering feeling his other self’s cock rub against his slit sliding up and down making his hips buck, even that bit of stimulation was almost too much.

Then Blue moved back just enough to let the tip of his member pop inside. They both moaned. Sans’ magic clenched around the head walls vibrating. Blue whined hips stuttering as he tried to thrust Sans’ pussy fluttering slowly parting under the ministrations.

Sans choked on a cry. Blue’s magic seem to buzz excitedly within him as he sank deeper in inch by inch spreading him open the stimulation was numbing his mind. His walls clamped around the other skeleton's dick halting his progress in increments.

“Oh gosh,” Blue breathed his mind spinning. Sans was so tight flexing and squeezing. His magic seemed to be sucking him further inside Blue rocked slowly until their pelvises were flushed together. Sans breath hitched with soft moans. He squirmed under his alternate self conjured walls pulsing from the sensation of being full. Blue panted phalanxes digging into the sheets. Sans felt even better around his member all moist heat and constricting walls. “Sans can I . . .?”

He received an affirmative sound in response and drew back thrusting in again. The sound of their mating was even more intense, Sans was so slick he fluttered around him magic dripping more with his excitement. Blue relished his increasing cries hands coming up to his other self hips gripping tilting them at a slight angle and delved even deeper.

Sans threw his skull back and wailed. He was so sensitive his pussy quivered as Blue sunk inside rubbing every part of him. He was picking up speed the other skeleton's energy getting the best of him. Even though he told Blue to take it easy he was starting to enjoy the overstimulation clouding his mind. He was getting close to his peak again.

Blue gasped feeling Sans clench around him. Pleasure curled in his body, ran up and down his spine, buzzed his the back of his skull. It was all overwhelming and he was getting close so close to coming. Blue fucked his other self babbling, “SANS MAY MAY I COME IN YOU PLEASE?”

“god yes,” Sans somehow heard him over his pitched moans. “please Blue-!” Sans wrapped his legs and arms around him squeezing his magic clamping as Blue thrusted once more. They both tipped over the edge seeing stars.

Sans came to being nuzzled and kissed Blue all but purring the lights of his eyes bright and shaped like hearts. “YOU ARE AMAZING SANS.”

“heh,” Sans laughed breathless tilting his skull to kiss in return. “you’re pretty sansational yourself.”

“MWEH THAT’S TERRIBLE!”

“but not untrue.” Even though he wanted to pout at the pun, Blue couldn't keep his grin down. Not with Sans staring up at him white eyelights equally bright and heart shaped. His breathing hitched when Sans flexed around him. He hadn't noticed they were still connected, a thrill went through him.

“Sans is it okay if I . . .”

“wha-what again?!”

“Please? I want to make you come again you feel so wonderful when you do!” Even as he was saying it Blue began rocking slowly. Sans fluttered around him moaning.

“oh hnnng sh-shit okay . . .”

“THANK YOU!” With that happy exclamation Blue thrusted in earnest.

“AND THEN SHE TRIPPED! UNDYNE AND ALPHYS WERE BESIDES THEMSELVES WITH DISBELIEF.”

“yeah i imagine that would work them up.”

“ALPHYS SAID SHE HAD NEVER SEEN A MORE UNCOORDINATED HUMAN IN HER LIFE AND WHAT ON EARTH IS THAT THUMPING?” Papyrus paused skull tipping. His other self doing the same standing in the doorway of their shared home. They both could hear a distinct rhythmic thumping from upstairs. “IS THAT YOUR BROTHER WITH A TRAINING DUMMY?”

ah so he confessed huh? Stretch thought dimly. didn't think they’d be at that so soon. “could be.” He shrugged.

Papyrus huffed. “TRAINING DUMMIES SHOULD BE OUTSIDE YOU CAN TRAIN MORE VIGOROUSLY THAT WAY. BEDROOMS ARE NOT THE BEST PLACES FOR FIGHTING.”

“you can tell him later.” Stretch reached out snagging his other self’s arm dragging him back out the house.

“NYEH WHY NOT TELL HIM NOW?”

“ah well y’know how training goes. when you start up you go into a head space to focus and whatnot.”

“OH YES VERY TRUE. I WOULDN'T WANT TO RUIN THAT. BUT WHERE ARE WE GOING?”

“to see a movie. my treat okay?”

“OH HOW GENEROUS OF YOU MY ALTERNATE SELF! I KNOW JUST THE ONE WE SHOULD SEE!”

“cool.” Stretch closed the door behind locking it once more.  nyeh heh heh have fun bro.
