All in all the date was amazing. You'd dropped Papyrus off at home then went home yourself. Everything was great. You and Papyrus were a thing, he trusted you with his biggest secret that you were going to keep, you kissed and you loved every second of it. Everything was right with the world. The next week whizzed by as you and Papy went on more date, or even just hung out and did homework together. "So how's Sans?" Papyrus looked up from his textbook. "HE'S BEEN.. TENSE. I told him that I showed you and I think he thinks something bad is going to happen. I don't think he's as ok with me telling you as he led me to believe." Papyrus whispered. Oh. "Maybe I can reassure him that everything will be ok? I haven't and don't plan on telling a soul." Papyrus smiled. "I know you haven't." He raised his voice to it's normal volume. "PERHAPS IF YOU COME TO DINNER TONIGHT, WE CAN REASSURE HIM TOGETHER!" Dinner invitation! Yes! "Sounds like a plan Papy!" You kissed his cheek and he turned tangerine. "I'm going to get ready. See you tonight! Love you!" He turned into a pumpkin. 'I love you' was still new to the relationship and still had you both a blushing mess. You'd said it to him first. "L-LOVE YOU TOO, [Y/N]!" He called after you, making you go cherry.

You were dressed in something casual, yet pretty as you knocked on the door to the skeleton Brothers place. Sans answered the door, tensing. "[Y/N]. didn't know you were coming." His voice was stoic. You couldn't read his expression. He stepped to the side letting you in. "Sans, are you ok?" He nodded. "'m fine. why wouldn't i be?" He replied, closing the door. "You look tense, your brother said that you were tense. Are you really OK with me knowing?" You went straight to the point. "sure i am." He replied. He wandered over to you. "i'm fairly certain you won't tell.."
"But not a hundred percent." You noted. Before he could answer, Papyrus came in. "YOU'RE HERE! THAT'S AMAZING! FOOD IS ALMOST READY IF YOU'D LIKE TO HELP!"
"actually, bro, me and [Y/N] were discussing something. can we finish the conversation?" Papyrus looked between you and Sans. "OH. ARE YOU HAVING THE TALK? I TRULY HOPE THINGS GO WELL.. I WILL LEAVE YOU BE THAN, BROTHER."
"Thank you, Papy." He nodded and went back into the kitchen. "you're right. i'm not a hundred percent certain, and i need to be." Your brows furrowed. "Sans, what does that mean?" The older skeleton's teeth sharpened, his eyelights flaring blue. "i'm sorry kid." His voice was a rough growl now, he jumped on you before the words could register. You cried out as his teeth sank into your forearm.

Papyrus POV

I should have paid more attention to his mood. I shouldn't have invited her over. I heard her scream and ran into the other room. Sans was crouched on the floor in front of [Y/N]. Her arm was bleeding, as she stared at him wided eyed. Sans spotted me. "i had to be sure, papyrus. she won't say anything if-" He was cut off as I slammed him into the floor. I never felt such rage as I did now. "WHY WOULD YOU DO THIS TO ME! SHE WASN'T GOING TO TELL!" I roared into his face. Sans bit my girlfriend. Next full moon, she was going to turn. She wasn't even given a choice. How could he do this?! "get off me, papyrus." Sans growled lowly. It wasn't a question. It was a demand. One I didn't want to grant, but my instincts made me. "I WON'T forgive you for this, Sans." I seethed. [Y/N].. I need to tend to [Y/N].. Sans sat up slowly, watching as I helped [Y/N] up and to the bathroom. He said nothing.

I washed the bite under warm water and wrapped it in gauze. "Are you ok..? Does it hurt?" She looked shocked still. "Did he just... d-did he just.." I nodded. "He did.. don't worry, [Y/N].. I'll help you through this." She nodded slowly. "I.. I don't know how to feel.." I hugged her. "It's alot, I know, but everything will be ok.." She hugged me back. "I can't believe I'm going to be a werewolf." I chuckled, trying to hide the growl imbedded within it. How dare Sans.. "How are you feeling?" The change affected people differently, according to something Sans said once. "Hungry. Is food done yet?"
"Yes.. it is."

Your POV

You didn't feel any different. You were hungry, but you had been hungry for the last few hours. We entered the kitchen. Sans was already sitting there, emotions still carefully guarded. Papyrus growled at Sans. "now that you're going to turn, you should know that i bit kyle too."
"WHAT?!" You and Papyrus exclaimed. "werewolves have naturally stronger immune systems. i did it so he could live a normal life." Sans explained calmly. "SANS YOU SON OF A-" Papyrus snarled. "Was it of his choice? Or did you do to him, what you did to me?" You're voice was icy cool, you still weren't sure what to think of all this. "it was his choice. i can promise that." Papyrus passed you a bowl. He hadn't made one for Sans. "shoulda figured." Sans sighed wearily, getting up to dish himself some.
