   Summary

   (I'm sorry i'm shit at titles)
   You (the reader) are in a fucked up, but committed, poly relationship with the skeleton brothers in Underfell. How or why is left unstated, but at this pint, both of them (and you,) have gone into heat.
   There may or may not be a preference to Papyrus, because apparently the author is fucking thirsty for him.
   As it turns out, not using protection resulted in a little... well, accident. (Mpreg warning! Ya boned paps)
