Chapter Notes So, winter requested classicberry with praise kink, and I think I did a pretty good job. Id you don't like it, or think I did something wrong, please tell me! "You're just so beautiful..." Blue panted at Sans, who was squirming quite deliciously under his body weight. Sans was just so beautiful, squirming, while he was buried deep inside his plump blue pussy. "N-ngh~ o-oh god, B-blue" Sans mewled, bucking his hips, and trying to push himself down onto the other's cock even more. Of course, Blue pulled him back up, not letting him have anymore pleasure yet. "You're going to have to wait, my adorable sans, because we aren't done yet..." Blue mumbled, flipping said skeleton on his stomach, before giving a few good thrusts. From the sudden movements Sans cursed. "A-ah~! F-uck!" Sans growled, gripping the covers of Blue's race car bed, as he spread his legs a bit more, for access tivity. Blue began thrusting, once more, at a slow and agonizing pace that had Sans mewling for more. For every thrust, Blue mumbled a word into Sans's ear, pertaining something to the former. "Alluring.." Another thrust, another moan, from his beautiful sans. "Adorable.." He whispered, making Sans whimper, asking more from his lover. Blue gave another slow thrust into the other. "Divine.." He growled into the other's ear, grabbing his shoulders, as he changed their position. Sans was facing forward, his back facing blue's front side. Sans was basically sitting on his lap. He bounced up, groaning, as he came back down, a look of absolute happiness on his features. "Blue- I'm home!" A voice called from outside his room, and down the stairs, from the entrance of the house. Blue put a hand over his lovers mouth, which effectively covered his loud moans. "Um, PAPY! ALPHYS IS COMING OVER!" Blue could hear an annoyed groan come from down stairs, as the same voice said "alright. heading to muffet's. see ya bro." "S-SEE YOU BROTHER!" Blue could hear the door close, as he sighed in relief. "Now... Where were we?~" Blue asked, smirking. Blue uncovered Sans' mouth as said skeleton let out a long satisfying moan. "The sounds you make are so beautiful, my love..." Blue whispered, unconsciously thrusting harder, which made Sans go crazy. "A-ah- blue- I'm, h-hah. About to Ngh~ cum" Sans moaned, bucking his hips once more to the pace of thrusts Blue was giving. "Me too, m-my love.. Where do you want me t-to cum?" Blie asked, his thrusts becoming sloppier and a bit more desperate. "I-inside- hah-h." Sans replied, arching his hips. His eyes turned to hearts an he came, his already tight pussy clenching over blue's dick, quite eagerly. After a few more sloppy thrusts, blue buried himself deep inside the other, and sticky, blue, strings of cum spurted out of his glowing cock. Blue pulled out, after a few minutes of heavy panting. "I love you so much, my dear..." He mumbled into the other's ear, as Sans feel asleep. "I love you too..." The other replied sleepily, basking in their own afterglow. Blue smiled, as he nuzzled up with his lover. Best night EVER. ***** Swapcest - Heavy Bondage, Overstimulation, and Sensory Deprivation. ***** Chapter Summary Blue and Stretch are having fun, but seems that Stretch can't take the heat. Chapter Notes whiskermoon requested: I really want too see a swapcest with heavy bondage, overstimulation and maybe sensory deprivation? So, I thought, what the hell, why not do all three? I hope you like this, And that you like this chapter! "Mweh.." Blue panted, a blue blush covered his cheekbones, as he struggled in the handcuffs. He knew that his brother was in front of him, but he couldn't tell where he was, due to the blindfold on his eye sockets. "P-papy... please.." He jolted, sucking up any saliva that had dribbled out of his mouth. "yes, blue?" Stretch replied having a very smug tone in his voice. "what is it that you want, pet?" Stretch tugged on the leash, that was currently attached to the collar on Blue's neck. Blue let his tongue lull out of his mouth, dribbling saliva. "P-please, let me cum, m-master" He begged, shaking his hips a little. "...maybe i will. well, after this" Stretch chuckled, and making some sort of movement. The next thing Blue knew, is that there was some kind of magic in front of him. "Suck" Stretch ordered. Blue tentatively licked the side of the accumulated magic, as he could feel his brother shudder, and the sucking of saliva. Blue enjoyed this feeling, having power over his brother, and licked again, but with less caution. He licked the head, lapping bead of precum over the head and his blue tongue. Soon, he took a bit of a chance and swallows his brother's cock, only about half way. What he didn't expect, is to feel his brother put a hand on his own skull, and press it down, so he was swallowing his whole cock down his throat. "take my cock, like the good little slut you are.." Stretch breathily moaned. It was hard for Blue to take his brother's cock fully, but it was doable. Blue tried his best, licking the sides, nuzzing with his nasal cavity, and using his tongue to massage the head. He could tell his brother was going crazy, but he could only do so much with just his mouth. However, the sweet little sounds his brother was making was only turning him on even more. The way he tugged his collar, the cuffs, hell, even the blindfold, made him even hotter. "M-master, may I u-use my hands to pleasure y-you..?" Blue asked, cautiously. Blue heard a hum of contemplation before he felt the pair of cuffs unlock from his hands. Blue smiled, but he released a squeal when he felt the cuffs get locked around his ankles. "You may. However, your feet will be restrained in place of your hands" Stretch smirked, enjoying the sight of his struggling brother. Blue nodded, and got to work again, it's not lie he needed his feet. Well, until later. Blue began to suck again, wet slurping noises filled the room, making him feel hot again, as he'd never felt this before. Whatever his mouth couldn't reach, his hands stroked the length of what wasn't covered. "W-wait!, b-blue, RESET, RESET!" Stretch panicked, screaming the safe word as if it was a lifeline. However, it was too late, as blue sucked, a little too much, as he felt strings of orange cum flow into his mouth, tasting a citrusy orange. "B-brother?" He panicked, taking off the blindfold, that was covering his ability to see. What he saw, was almost too much for him handle. He saw his brother, twitching, his eyelights rolled up into his skull, which made his eye sockets look empty. After a few minutes of Blue starring, Stretch woke up, shivering. Blue grinned uneasily. "Little bit to much, huh Papy?" He asked, as Stretch nodded his head, still shaken up. "Mweh Heh Heh" Blue laughed, his eyes turning to amused stars. Stretch playfully glared at him. "Shut up" Stretch said, averting his gaze to something else. Blue laughed harder. ***** Redpuff - Voyeurism, Crossdressing, Eating Out ***** Chapter Summary Red takes Papyrus on a date, but red gets flirted with, and Papyrus thinks he's not enough. Red proves him wrong. "R-red, do I have to show you..?" Papyrus whimpered, from behind his bedroom door. He could hear a chuckled from the other side. "you don't have too... but i'd appreciate it.." He heard his boyfriend reply. So papyrus didn't have to do this! But, his boyfriend offered to take him on a date, so he would do it! He was The Great Papyrus after all! He slammed the door open, starling red, who was on the other side. When red finally gained enough consciousness, he looked Papyrus, up and down. "damn sweetheart. you look great..." Red scanned him once more, before taking his hand and shortcutting to a place called 'Bon Appetit'. "And to believe that's all mine, sugar" Red growled, pulling Papyrus down to his eye level, and giving him a kiss, just to justify his point. Papyrus nodded, a flustered orange blush covered his cheekbones. Red looked over his boyfriend, once more, just in awe, at how cute one can be. They walked in the restaurant, and you could tell, Papyrus fit in, by how he was dressed. His own dress was long flowing, going down to his feet, and for a special occasion, he wore heels. 3 inch ones, actually. He had to get edge to teach him to walk in them, without falling, obviously. The waiter asked for a reservation name, which red dutifully supplied. After they got their table, they made small talk, ordered their food, that is, until a small bread basket came. Red rose an eyebrow, and mumbled 'we didn't order this..' The waiter simply said "Compliments from the blonde lady" before walking off. Red glanced behind him, and sure enough, a bust, blonde human chick was giggling at him. Papyrus got up, and walked into the men's room, crying a little. Red tried to follow him, the blonde blocked him from following his boyfriend. Meanwhile, Papyrus was crying. Was he not good enough? Does red not like him? Was he not, attractive enough? Red bursts into the bathroom, and tackles Papyrus to the ground, kissing his cheeks, crying soft red tears. "i'm never taking you to this place again.." Red growled, taking papyrus' hand, and leading him into a stall. Red kissed him again, pushing him against the door of the stall. "R-red.. stop" Papyrus moaned, when red seperated, and started to suck his collarbone. "Nope. I'm going to make you mine, right in this restaurant" Red mumbled into Papyrus' ear. Papyrus moaned softly again, squirming against the door. "N- Nyeh...AHH!" He screeched when red laced his pelvis with his fingers. scratching, which made Papyrus go crazy. Red chuckled as he continued to rub the other's pelvis sensually. "maybe, if ya summon something.." Red bartered, enjoying the soft moans that Papyrus gave him. Papyrus didn't need to be asked twice, as he summoned his bright orange ecto-body, along with a dripping cunt. Red chuckled once more, before he went under Papyrus' dress. "R-red, p-ple- N-NYEH!" Papyrus screamed as red's tongue, licked at his clit, before the fat, thick, and wet tongue rolled inside him, licking at his folds, and enjoying the sweet moans and mewls that split from his sweet papyrus' mouth. "O-oh god, p-please... Nyeh.. I need,~ more~~!" Papyrus moaned, bucking his hips into Red's face, making the tongue brush over his g-spot. "O-Oh Y-yessss~!" Papyrus hissed, arching his back, as he felt a coil in his stomach. Heart eyes made their way onto Papyrus' expression, as his own tongue lolled out of his mouth. Red's eye widened, as he snapped his fingers, red tongue still in cunt. Suddenly, they were in his own messy bed, as he pulled out his tongue from the inside of Papyrus. "ready for the rest~?" ***** The Exorcist - Fingerfucking, Cum Eating ***** Chapter Summary I call this ship the Exorcist, because it's a classic horror movie, but you can use any classic horror movie you want to talk about this ship. Sans hummed as bloodied snow crunched under his pink slippers. This universe was really giving him the creeps, and it really sent a shiver down his spine. Next thing he knew, he was tackled, by another skeleton. The other had a big hole in his skull, which freaked sans out internally. "Well, would you look at that? A cute, small, copy of me~" Horror cooed, gazing at sans, from on top on said latter. Sans' grin tightened, as Horror closed that gap between them. They clinked teeth, as sans' eyesockets widened. "Hey- stop that!" Sans panicked, trying to push horror away, but the latter was just way to big for sans to push. Horror growled, as he pushed sans down to the ground as he stared back at the smaller. "Just lay back, relax, and we'll have some fun~" horror growled, tracing the edge of the other's shorts. Sans stared, before he eventually stopped. "Alright then. Carry on. We can do this, as long as I can go back to my universe" Sans grinned, laying down as instructed. Horror actually stopped functioning for a minute, as this small skeleton actually gave him permission to do whatever to him. When Horror finally unfroze, he noticed something was different. He glanced down, and sure enough, the other him was sucking his dick like it was a lollipop. Now, being aware of that, he shuddered, and tried to cover his moans with his hand. Sans grabbed the hand, pulling it down. "I like hearing your moans. Don't stop...." Sans begged, before going back down to Horror's cock. Doing as requested, Horror let his moans fly free, filling up the air around them. Eventually, Horror cummed, letting out a long and satisfying moan. Sans looked up at the bigger one, smirking. Horror returned the smirk, only bigger, and it filled with a sort of malice. Horror pushed sans back, and used a finger, sticking it inside sans' cunt. Said skeleton squeals at the sudden intrusion, as horror used this to push his finger in further, exploring the hot wetness. Sans moaned, and wiggled his hips into the finger. "M-more.." He orders, giving a piercing glance at the other. Horror chuckled, before sticking another finger into the smaller one. Sans jolted up, before lowering his hips to match the pace of Horror's fingers thrusting into him. "F-uck! Fuck me h-harder..." Sans moaned, arching his back, which gave Horror more motivation. He added another digit, and thrusted even harder than before, and hitting sans' g-spot. Sans' cunt clenched down on his fingers, as he came, a light blue color. While sans was still panting, Horror brought the cum covered fingers to his mouth, and licked the cum, till it was all gone. "That was good, little one. We're going to do this alot more~" Horror teased. Sans gulped. ***** Swapcest - Masturbating, Watching Kink, Doggy Style ***** Chapter Summary Stretch walks in on his brother masturbating. "Hah...Papy" Blue moaned as he took another deep breath of his brother's hoodie. Cigarettes and Honey. That's what his brother smelt like. And how addicting that smell was. It drove him crazy every time he gave his brother a hug, and was getting hard to hide. This is why he does this, every so often, to release tension. "Hey sans, have you seen my-..." Stretch opened the door, glancing around, as he saw his precious and innocent brother, finger s shoved inside his tight blue cunt. Instead of walking out, and apologizing like a normal brother, he shortcutted out the room, and came back, a chair in hand. "Papy...What?" Sans replied, a certain dazed look in his eyes. "Masturbate in front of me" Stretch ordered, sitting on the chair, and propping up a leg, as if he was getting comfortable. "What?" "You heard me. Do it." Sans, slowly, and reluctantly, layed down on his stomach, and began to thrust his fingers inside himself again. "Ah~ Papy~" he moaned, as a finger brushed over his g-spot, making him buck his hips a little. Stretch was still sitting, smirking at his little brother. "Lay down on your stomach." He ordered, summoning his own ecto-body, and a long, orange cock. "Papyrus~ Fuck me~" Blue whined, saliva dribbling out the corner of his mouth. "My, of course~" Stretch grinned, lining himself up with his brother, before thrusting inside. "O-oh Papy~" Blue moaned at the quick and sudden movements. Stretch didn't give Blue time to adjust to his full size, as he started to thrust, wiggling his hios a little, and fucking sans from a different angle. Sans propped himself up on his hands and knees, his tongue lolling out of his mouth. "Sans.." Papyrus growled, thrusting into his brother, going faster than ever before. Sans arched his back, and wiggled his hips as he came, clenching down on his brother's cock. A few more thrusts, and Stretch came, inside his brother. "I'll be taking my hoodie, thank you." "HEY!" ***** Kustard - Rope Bondage, Master/Pet, BDSM/Hitting. ***** Chapter Summary Red and sans have sex, with ome gentle aftercare. Chapter Notes Requested by 'kustard lover who needs a life'. they said that they wanted these kinds, but I added the BDSM! I though that it fit for the situation! "Red, please.." Sans said, struggling with the ropes around his naken skeletal body. His ecto- vagina was dripping, aching, for his lover to fill him. Red grabbed sans' cheek, and rubbed it tenderly, before slapping him."what did I say about calling me red?" Red growled, before rubbing his cheek again. Sans winced at the slap, before his tongue lulled out of his mouth. "Please, h-hit me more, master!" Sans begged, bucking his cunt onto red's leg, still very tightly secured in the ropes. "you want more, you dirty slut?" Red panted, giving sans a well deserved kiss. "Hah.." Sans moaned into the kiss, as their tongues intertwined, Sans tasting the addictive cherry flavor that he loved so much. "Hmm.." Red hummed, reaching into sans' ribcage, and pulling out the baby blue soul, that belonged to the other. Red gave the soul a lick which sans shivered from, and he put the whole thing in his wet mouth, covering the soul in wet warmth. "now, what do you want, slut?" Red asked, eyeing sans deep in his eye sockets. Sans bucked his hips, his cunt rubbing into red even more, a pleasant heat radiating from it. "M-master, please, fuck me!" Sans begged, a moan lacing his words. Red glanced at the other. "not yet" red ordered, taking another lick at the oher's soul, which made sans shake. "pleasepleaseplEASE! NGH~" Sans begged, but red gave a hard bite to his soul, as the owner of it, went absolutely crazy. Sans was shaking his head, buckinging his hips into the air, hell, he was even arching his back as far as he could. Red gave another bite to the light blue soul, making sans give another long, drawled, moan. After that, his vagina, twitched, and tightened visibly. Sans gave another moan, struggling in his bonds. Another loud mewl that drove red crazy, and sans squirted like a fountain. Sans' cums squirted up, glowing blue, as the skeleton threw his skull back, salvia dribbling out of his mouth without a care in the world. "Hah.." Sans panted, giving red a soft smile. "that was a really rough orgasm, sweetheart. you alright?" Red asked, getting closer to his lover. Sans gave him a soft kiss on his nasal cavity, and whispered "i'm alright, love". For the first time in a while, Red lit up, well, red. how he loved that nickname his lover gave him. He'd cherish it forever. ***** VenomHoney - Humiliation, Public Hand Job, Name Calling (Only a little). ***** Chapter Summary Stretch and Razz are on a date, and Razz decided to have fun. Chapter Notes Requested by sp00kysc4rysk313t0ns, as they wanted humiliation. Hope this is good! <3 "Razz, please.." Stretch begged, already basically glowing a bright orange. He was in muffet's on a date, obviously. Now, what wasn't so obvious was that someone would come and see his boyfriend touching him so lewdly in a family restaurant. He could barely keep his moans in, and it sounded as he was breathing very raggedly. "Y-YOU'RE GETTING OFF ON THIS, AREN'T YOU SLUT?" Razz chuckled, a little bit of disbelief laced his words when he started this sentence, but, he simply got more braver at the end of his sentence. They didn't order yet, however, out of the corner of his eye socket, Stretch could see a waiter, that was going to take their orders. The waiter sharply turned the corner, a monster to be specific. Nothing special, just a dog monster. "Hello sirs, I'll be your..." The dog monster froze, as its nose twitched, and started to sniff around, looking more disgusted by the second. "WHAT'S WRONG?" Razz asked, raising a skeletal brow, still touching his boyfriend however he pleased. It was still getting hard for stretch to keep in his moans. "Nothing, it's that I can smell sex in the air" The dog monster shuddered. "I can't imagine a person doing that in a family restaurant" The dog seemed out of it, before it went back to his customers. "Anywho, I'll be your waiter, and i'll taking your orders" The dog barked happily. Stretch froze. He gulped as he looked over to Razz. The bastard was going to force him to order, wasn't he. And the look Razz gave him confirmed his suspicions. "I-i'll have a, Hah~" Stretch twitched as his boyfriend stroked his length, and lapping precum over the top. The dog looked at him weirdly, before Stretch carried on with his order. "A, s- spider donut, with cider, Ngh~!" Stretch moaned as Razz purposely squeezed his cock, teasingly. The dog gave another weird look. "andabottleofhoney" Stretch squeaked, as the waiter nodded, and went to Razz. "And what would-" "SPIDER CAKE, WITH SPIDER CIDER" Razz interrupted, as he glanced at stretch, who was giving him such a lovely expression. "ah~ Fuck!" Stretch groaned as he came while in his seat. This time, the whole restaurant heard him, as all sound froze, and even kids stared at him. Stretch blushed a dark orange as the blush layered. "T-that's all..." Stretch whispered, signaling the waiter off, who gladly walked away from the couple. He could hear Razz snickering, and he gave a small swat at the shorter skeleton. "Asshole" Stretch growled, giving the other a glare. Razz simply laughed loudly. "MWAH HAH HAH! BUT I'M YOUR ASSHOLE!" Razz cheered. Stretch gave a small smile, pulling the other into a kiss. "That's right"   ***** KetchupHoney?? - Slight Praise, Frottage, Grinding, Sex/Masterbation While High?? ***** Chapter Summary Sans and Stretch get on a subway to go to the park, while high, and Stretch feels horny halfway. You can guess what happens next. Chapter Notes GoldenSpite requested this, sex while high! I think I fucked up, but tell me what you think, hun! "Stretch, stop.." Sans moaned, his tongue already lulled outside his mouth. Said papyrus was currently grinding against his erection, which was tightly pressed against his basketball shorts. Stretch, from behind Sans, licked his neck, and grinded some more on the crowded subway. "Nope.." stretch replied, giving Sans another lick on the next, causing the shorter one to give a small, and hopefully unnoticeable, groan. Sans pushed his hips into Stretch's, hopefully to gain some friction, and he did. Small, but audible moans made their way to Stretch's ears, as the said skeleton smirked from hearing the small, addictive sound. "So cute.." Stretch praised, grinding on the other a bit harder, still grinning just as hard. Sans let out another ever so cute moan, and he hoped that the rest of the train couldn't hear the couple. "S-stretch please~" Sans pleaded, dropping to his knees, his top half of his body pressed against the door of the subway. "Please what?" Stretch asked, blowing some cigarette smoke into Sans' face. The only way they were crazy enough to do this, is while either they were High, or they had some alcohol in the vicinity. Sadly, there was no alcohol, however, Stretch was practically loaded with weed. They smoked some, and decided to go to the ark, which was on the other side of the city. What better way was to take the subway? However, Stretch started to get horny about half way, and started to grind into Sas, who was unaware of the other advances. Only when Stretch pushed him against the door of the subway was when he realized that Stretch wanted more. "Please, finish~" Sans begged, lifting his ass into the air, some saliva dribbling down his skull. Stretch nodded, and started to grind into Sans, the hardest that he could. After a few more minutes of the friction, Stretch jolted, and let out a long grunt. Stretch came inside his cargo shorts, as he heard another sweet moan from Sans. The skeleton had came inside his own basketball shirts, some of it dribbling down his femurs. The doors opened, and Stretch and Sans both walked out. ... They hoped nobody heard them.
