Summary
Life is funny like that, you sure didn't expect to pick up an injured skeleton off a back alley(both metaphorically and physically) only to be sent into a completely different universe with said skeleton and his brothers who seem to just hate you with a burning passion! What follows that? Well more skeletons of course! At first glance they seem like a perfect odd family but is a normal family usually filled with emotionally unstable, depressed, ptsd infested monsters who seriously need therapy and a brat energy check? NOPE ! and just when did you turn into a therapist?!

Summary
Four AU’s have come to a happy ending on the surface. It is a new beginning for everyone, but Berry is haunted by his past that still clings to him and threatens to pull him back into the darkness, unknown to his now growing skeleton family. The newest skeletons are from the last set that surfaced: Fellswap. They are not going to let Berry be taken. Howl and Daemon, the two newest skeletons, have to dig into a horrible truth and show the world Berry’s past, and with the help of their fellow skeletons, they hope to make a better future for him and all other monsters.
This is adapted from a role play with GetMcDunkedOn and me (Diyami). I hope you enjoy it.

Summary
Being a skeleton is confusing at times, but wait -you’re NOT a Human skeleton- you’re a MONSTER skeleton and doesn't that just make things worse? Sweet Asgore, you've been steadily creeping towards that ~climax~ in your relationship with Frisk. She's wonderful, but human, and humans have certain ~needs~ you hope to ...fill.
How's this supposed to work when sex is just so confusing?
