~ Cherrytober prompt day 1 scent ~

You and a group of friends years ago all decided to do a ritual and your grandmas basement. Everyone freaked out because they heard a noise and ran upstairs except for you, instead of a demon or any possible thing that could’ve been summoned you guys summoned a vampire. The vampire appeared and could smell that you were on your period. You were terrified however you both made a deal that he will have to leave you alone. But in order for this deal to match his standards he required it to also be apart of the deal that every month on your period he can hunt you down to claim you.
