"Trying to swindle a demon? I like you already.."

Kinktober day 8: Monsterfucking

Summary:

You decided to make a deal with a demon, youre greatest desires in exchange for your firstborn. However, as soon as the deal was done you got your tubes tied. Now Melzeel found out about your little loophole and decides to punish you. ;)

As usual, not much about you is specified other than being afab and that you don't want kids. I'm probably gonna make the "greatest desire" something related but the specifics are up to you bookie. Also ik you can't get your tubes tied unless there's some medical reason but let's pretend thats not the case for the sake of getting down and dirty with a demon :P
