Papyrus said nothing for a time and Sans could imagine the disgusted look on his face. Eventually Papyrus’s hand slipped off his wings and the burn returned, Sans was sure he was leaving. Suddenly Sans was enveloped in a hug and the burn lessened.

“You could have told me sooner. You shouldn’t be sorry. I’m sorry.” Papyrus whispered.

“Papy….” Sans trailed off, unsure what to say.

“Sans, what’s wrong?” Sans felt a small laugh bubble in his non-existent throat. Just like Papyrus to get right to the point.

“My magic was acting strangely so I came in here and when I did, my magic began to hurt.” Sans knew there was no point in hiding it.

“Does it still hurt?”

“Little bit but when you touched my wing it eased it, but when you stopped it flared back up.”

“That’s odd.” Papyrus voiced both of their thoughts. Both mulled it over when Sans got the idea to take a closer look at his magic. Upon looking at it, he noticed what was wrong and he inwardly cursed.

“Fudge.” Papyrus looked at him curiously.

“What is it?”

“I know what’s wrong.” Sans looked at the floor to his right, finding the messed up blankets there very interesting.

“Will you please tell me?” Sans could feel the pleading gaze.

“Are you sure?”

“Of course! I want to help you, I haven’t been of much help before this.” Sans took a deep breath.

“I’m in heat.” Sans stated simply. Omega’s went into heat when they felt safe and were at a certain age. It helped them find a mate, mates were permanent. It could be staved off without the Omega getting a mate but it was hard and painful.

“I thought that only...”

“I am an Omega.” Sans cut in, he hated interrupting but he needed to. There was a pause and the statement hung in the air, making it seem stuffy.

“Will you let me help you with it?”

Sans’s eyelights widened in surprise and his head snapped over to Papyrus’s confident, yet soft, expression.

“D-do you understand the implications of what...”

“Of course” Papyrus interrupted. “But if my touch is soothing your pain, that means you love me more than a brother, correct?” Sans blinked and looked to the side sheepishly, Papyrus was really smart.

“Yes.” Sans whispered.

“I love you more than a brother as well, at first I was so confused and I ignored it. I can’t anymore. Especially now that you need me.” Sans hadn’t started giving off an alluring scent that came with his heat. So that meant Papyrus was telling the truth and his mind wasn’t hindered. Tears welled up in Sans’s eyes and he hugged Papyrus.

“Thank you.” Sans mumbled into Papyrus’s hoody. Papyrus suddenly picked Sans up bridal style. Surprised by the sudden movement, Sans squeaked and gripped Papyrus’s hoody tightly. Papyrus chuckled. He walked over to Sans’s bed and placed him down gently, hovering over him. Papyrus was still touching him but Sans could feel Papyrus’s eyes scanning every inch of him. Sans’s wings floofed and his tail curled on his non-existent stomach in embarrassment. Papyrus rested his forehead on Sans’s.

“Don’t be embarrassed, I’ll be seeing more of you soon.” Papyrus’s voice went down an octave as he purred, Sans felt shivers go up and down his spine. Papyrus planted a chaste kiss on Sans’s teeth. Sans leaned up and kissed him again. Papyrus growled and kissed Sans fiercely. Sans realized in the back of his mind that his heat scent had released. Papyrus licked at Sans’s teeth with his burnt orange, magic tongue, demanding entrance. Sans’s mouth opened and his own bright blue tongue met it. Papyrus tasted like orange chicken. Their tongues tousled for a moment before they separated, taking deep breaths they didn’t need.

“Blueberries,” Papyrus rumbled as he nuzzled Sans’s neck as his hand trailed downward, drawing out gasps and moans from Sans as it floated over his bones. When he reached the waistband of Sans’s jeans, he hooked his finger in them and slowly tugged them off, revealing a slight bluish glow in Sans’s pelvis. Sans flushed as Papyrus began rubbing it. As he rubbed, the magic started to form. It creeped over Sans’s bones, forming an ecto-stomach and legs halfway down his femers. His ecto-stomach had a four pack and below it a pussy, dripping slick. Sans’s tail flared and covered Sans’s pussy.

“Now, now. No need to hide.” Papyrus gently grabbed his tail and pushed it gently aside. Using his other hand, he circled Sans’s opening. Sans was about to tell him to just get on with it but Papyrus suddenly stuck two fingers inside. Sans gasped and moaned, his back arching into the phalanges. Papyrus smirked and Sans’s tail wrapped around his spine. He gasped in surprise and shock. Papyrus had not been prepared for the touch, nor for the surprisingly coolness of the flame. Sans’s hands gripped the sheets tightly.

“Papy~ Please, I need you!” He whined.

“I am right here, so tell me what you mean.” Sans was about to retort when Papyrus’s fingers pulled out and his fist was eased into Sans’s opening, causing him to groan.

“I-I…” Sans couldn’t seem to form the words as Papyrus’s fist pulled in and out, in and out.

“You what?” Papyrus teased.

“Damn it! Just fuck me already!” Sans cried out. Papyrus paused for a moment then chuckled.

“You’re fun to mess with when your all hot and bothered. Alright, I’ll give you what you want.” Sans wanted to yell for Papyrus to hurry up and, in the back of his semi-rational mind, scold him for laughing at him. But Papyrus pulled out his fist and quickly replaced it with his cock, which was a bit bigger. Sans gasped as Papyrus thrust quickly. He clung to the others hoodie, back arching. Papyrus nestled his head in the crook of Sans’s neck and rested his tongue on it. With each thrust, it dragged along Sans’s neck. Sans keened and he came, the stimulation being too much. Sans’s entrance gripped Papyrus, causing him to cum as well. Sans milked Papyrus and soon fell limp. Papyrus fell to the bed beside Sans, breathing heavily.

“Soul bond?” Papyrus nodded, without a soul bond, it would be almost non-stop sex for several days. A soul bond couldn't be forced, it had to be a mutual want, desire, and love. Papyrus summoned his white soul surrounded with a burnt orange glow and Sans, his white soul surrounded in an icy blue hue. Papyrus’s seemed to be smooth and warm. While Sans’s seemed to be on fire with the icy blue flame that made up his tail. The souls lazily floated towards each other, as though pulled by some unknown force. When they touched, emotions flooded into Sans, images passed before his eyes in a flash and he saw the RESETs but from Papyrus's, him writing the letter as he fell and the happy times that had happened recently. He felt the absolute happiness that came from Papyrus at finally being bonded to the one he loves the most.

“Y-your the Judge?” Papyrus gasped after the onslaught settled down.

“Y-Yeah”

“You also have the six-souls and aren’t actually my brother.”

“Yes.” Sans whispered. Papyrus was silent for a moment and Sans looked away. He couldn’t bear seeing the disappointed look he was sure was on Papyrus’s face. Suddenly, Sans was wrapped in a bear hug.

“I’m not disappointed, I’m glad actually. Because it means that we can be together without any trouble. I can understand not telling me about you being the Judge.” Sans hugged him back, tears coming to his eyes.

“Thank you.” He whispered.

“Now, now” Papyrus rubbed Sans’s back. “How about we go to Grillby’s?”

“You hate Grillby’s though.” Sans sniffled.

“Yeah but you like it. So, let’s go.” Papyrus chuckled. “After we get cleaned up.”
