Summary
You didn't expect life to throw you a bone, but here they were: two tiny Bitties that wrecked your heart and filled your home. Sure, your tiny city apartment didn't have the fancy stuff that others had, but you've always gotten by.
And it was a lot better than what they were used to.

Summary
A sharp yank on the leash cuts him off, and you’re pretty sure he fucking shudders.
“That’s not how this goes, bone boy.” Your voice turns steely. “No topping from the bottom with me. If you want something—” you wrap your hand around his lumbar spine and pump, pulling a strained gasp from his teeth, “—you ask me for it nicely.”
Despite his predicament, Sans manages a chuckle, once again treating you to that insufferable grin. “really, sweetheart? gonna make me beg or sumthin’?”
You tighten your hold on his spine, rejoicing in the way it has his eyelights glazing over. “For that little piece of backtalk, I will.”
Sans bares his teeth. “make me.”
Your lips twist in a cruel smirk. Oh, how you’d hoped he’d say that.
Shameless smut featuring Underfell Sans. Reader has a vagina; no pronouns or gendered nicknames are used.
Now with two more installments!

Summary
You live in a world where your soulmate's first thoughts when they see you are written across your skin.
You don't really have time for love though.
Nor do you know how you got that soul mark.
Also, what the hell was this person thinking when they initially saw you?Bookmarked by K_a_s_u_m_i
