>>29534485Weaviles are sluts, but you also have to account for the nature of what makes things dark type to begin with. A little bit of cruelty and a lot of dominance are good places to start in defining the interaction. The encounter itself is going to be very much a flavor of something only around 3 feet tall putting something else nearly twice that size into submission, but the Weavile's personality may differ in whether it chooses to tease or get to outright fucking.
The human side I have no experience with, I am a degenerate at heart.
