Good smol berry and the edgy smol berry

Senarios:
#1 - So SF and Blue are already in a relationship but at some point one of them gets bit by something and either becomes a vampire or werewolf

#2 - something involving Lamias
-pictures if ya don't know what a Lamia is- (also, just as a note if sin happens involving the lamias, they'd have two dicks, since snakes have two -w-)

#3 - come up with something .w.
