You were walking in Papyrus's home... as You see him looking at you... However his expression seems to change into Annoyed but he blushes orange a bit... As he walks to you, as He sits on the couch besides you as he looks at you. He then summons orange sharp bone as it stabs you in Chest... As you pass out from blood loss, he then picks you as he carries you into his room as he enters it... He then lays you down on the bed as he covers you in his blanket... As he spoke in low and Calm tone.

Fellswap Papyrus: Sleep tight, Kid.

He then looks at you.

Fellswap Papyrus: Gosh... I think My bone damaged... HIS SOUL...

He then carefully pulls out a bone from your chest as he puts his hand onto your chest... and pulls out your SOUL. He then chuckled dominantly.

Fellswap Papyrus: It seems that it now has some cracks. Welp, it would be mark for who he belongs to!

However you woke up as Fellswap Papyrus Puts your SOUL back into your body... As he gets onto the bed. As he blushes Orange as His Soul glows through his tank top and jacket as it beats very fast from excitement.

He then slowly pins you down bed as he starts to cuddle with you, he holds you into his embrace, he kisses you in mouth to mouth. As he spoke in Dominant and Excitment tone as he tightens grip... and lays onto bed besides you... as he his cuddles turns into a bear hug...

Fellswap Papyrus: Don't worry kid... I'm gonna have a great time

Then he suddenly pulls you against him as he rolls you to face him as you look up at him in fear...
