What? Papyrus was sure that Sans would've knocked out cold after he left. He was barely keeping conscious before he had left his room. A shot of panic raced through him at the thought that he might've lost Sans. He flicked through his other cameras, but there were so many and he was too panicked to really pay good attention to each camera's contents. So instead, he went back to his room's camera and played back the time.

There was Sans right after he had left, shaking and breathing hard as he lay on Papyrus's bed. Papyrus frowned, speeding up the time. About 5 minutes after, Sans struggled, then pushed himself up shakily before standing and walking out of the room.

Papyrus followed the outside hallway's camera, watching as Sans entered the nearest bathroom. He switched to that bathroom's camera, seeing Sans enter and strip his shirt off. Sans turned on the water in the bathtub, then lowered his naked self into it. He had left the drain stopper up so the water was constantly draining as it entered the bathtub.

Sans looked incredibly tired, barely able to keep himself awake, but he picked up a bar of soap and used it to scrub off the excess cum on his body. Papyrus focused on Sans's face, but he betrayed no emotion, just seemed to carry about his job with a single mind.

After he was finished, he pulled himself out of the bathtub. Papyrus winced as Sans wobbled dangerously once he had left the bathtub, falling to his hands and knees. Sans huffed a little, his small body trembling from the exertion, but he managed to get back on his feet and dry himself with a towel.

Sans grabbed his shirt, then walked back to the hall, his steps unstable all the way. He entered his own room, Papyrus switching cameras to accommodate, and Papyrus watched as he threw his shirt on the floor and flopped on his bed with a huff.

He was instantly asleep, not even bothering to cover his naked bones, so tired as he was.

Papyrus shut off his computer, getting up to go to Sans's room. He knew he would be there. As he entered the room, Papyrus picked up the discarded shirt, then walked over to the side of Sans's bed.

Sans was sleeping peacefully, though he had to be cold without a blanket. Papyrus went into the closet, taking out a spare one and covering Sans with it. He watched the rise and fall of Sans's ribs, relief pulsing in his soul that he hadn't lost Sans. That he was still here.

Papyrus leaned down and placed a gentle kiss on Sans's skull before leaving the room, shutting the door lightly behind him.
