The night slowly crept in as the brothers walked home. Papyrus was humming one of their most admired songs, unbeknownst of Sans' staring. "I'm a new soul, coming to this strange world, hoping I can find some-" Sans constantly glanced endearingly at his older brother, listening to his calm and soft voice. It was odd for Papyrus' voice to be so soft considering his smartass comments nd gestures at times. Sans ignored this minor change and just listened, soon joining in the little song his love sang. "I love you, Paps. Don't change.... Please...."

Papyrus chuckled, lifting his waifu into his arms, "Who said I was going to? nyehehehehe...." Sans blushed realizing how loud he spoke. "U-Um... Uh... I didn't m-mean to..." Sans looked down, burying his face in his cyan blue scarf, a blue haze consuming his entire face. Papyrus shifted his orange hoodie sleeves and engulfed Sans in his arms. He buried his face, tightening his grip, deep into Sans' neck, before licking him with his orange tinted translucent tongue. "P-Papy.... N-nnngh...."

Papyrus continued licking before jolting straight. He shivered, before setting Sans down roughly, "Oooooooooh, shit..... H-Heya...... A-Alphys...." Sans spun around and shivered, "Oh n-noo.... A-Alphys... I-It's not... What it..." Alphys flashed a huge grin, "I fucking KNEW it!!! Undyne, your OTP is for REAL!!! HAHA!!! Hey, chill... I don't mind..." Alphys grinned and began trying to soothe Sans, who had hyperventilated from fear. Tears streamed like a flood down the poor skelebaby's cheek as Papyrus rubbed his shoulders. He sweetly spoke to Sans, "Hey, Sansy... It's ok, Alphys isn't going to take your dream away... Right?" Alphys nodded in agreement, "No, never..." Papyrus continued, "And even if she had, I'd make 100% sure that you get it back, even if it means I'm being hated. I promise..."

Sans hiccuped before rubbing the excess tears away, "R-Really? You... Mean it?" Papyrus nodded, "Of course, I'll always put you before me, and if I ever do the opposite, you can do whatever you want to me, ok?" Sans blushed, and pulled Papyrus into a kiss. Alphys stood, trying to conceal the squeals that were escaping her mouth. "So... When's the date?" Alphys teased as she watched the two Skelelovers blush their respective colors. "A-Alphys...." Sans hid his face, embarrassed beyond belief. Before long, Sans hand cuddled against Papyrus's chest, hugging the soft warm fabric that stood between him and the fabric Papyrus wore underneath.

Papyrus softly chuckled as he stood up straight. His brother clanged to him like a spider on its web. "Oh, Sans... Don't stop being you..." He kissed Sans' forehead before stumbling towards home, Alphys trailing behind for precaution. "Well, you two love birds... I think I'll beheading home now. It was nice running into you both. Also... Keep bangin'... HAHA!!!" Papyrus hesitantly laughed, his face flushed from Alphys' lewd comment. Sans was fast asleep, which made Papyrus ease up. He sighed and wobbled towards Sans' room to drop him off when he clung harder.

"S-Sans.... C-come on... You're in bed now, please... Let go..." Sans' eyes opened lustfully, shocking Papyrus. "Is Sans just now getting in heat? It was too late for him to, though..." Papyrus worriedly thought to himself. He shrugged it off and tucked Sans in, fighting him in the process. After 30 or so minutes, Papyrus managed to tug his horny brother off and escape. With a sigh, Papyrus walked to his room and closed the door. He was finally alone in his room... Or so he thought.

Papyrus woke up to the sight of darkness and the sounds of moaning. He shifted but felt a heavy weight resting on his waist. Whatever was sitting on his waist, was having the time of its life as Papyrus seemed to be panting with it. Papyrus soon realized nearly instantly that he was being raped and tried fighting the rapist off. With a pained grunt, the rapist fell off with surprisingly little effort and gasped. It sounded like Sans... "S-Sans?! Is that you?!" Papyrus lifted whatever was blocking his view and was memorized. The person who was fucking him was Sans himself; Papyrus' one brother he didn't expect to be so lewd. "S-Sans!!! W-What were you d-doing?! Why we you- G-GYAHHH!!!" Sans kissed Papyrus, interrupting him mid sentence, and grabbed his dick, brushing his clit against it.

"~P-Papy... Nnnnggh~ I looooove you sooo much~<3" Sans began drooling as he rubbed his clit and entrance against his brother's head harder and harder. Papyrus moaned with pleasure, "G-Gyahhhhh, S-Sans.... Mmmmmmmmmmm..." Sans blushed once more and thrusted roughly, making Papyrus almost jizz that second. Papyrus pushed at Sans and pulled out before cumming. "A-Ahhhhhhhh.... Ha.... Ha...." Sans sat up from being pushed and smiled as the warm orange strings of cum trailed from his entrance to Papyrus' dick. "S-Seems you didn't quite get it a-away... Huff... Puff..."
