Canon Underswap Sans!

Mentioned characters include: Papyrus + Alphys

Not to mention: He is not blueberry or the cuter version of sans nor underaged!! He is 21 and i did it as accuret as possible.

Authors note: Okay, i did try to add the ecto or echo body thingy into this despite having had to suffer watching through all these NSFW images (╯°□°)╯( ┻━┻. I hate, HATE watching him being shipped with his BROTHER. But i pulled through and here you go, canon as it can be \ (•◡•) /.
