Hexy

Hexy is a goblin witch who specializes in potions, elixirs and various other brews. Hexy isn't her real name, but rather a nickname she took up after starting out as a witch. She's also part of a coven with two other witches who both specialize in different things than her.

She's always excited to get her hands on new ingredients to find out what they do and how she can use them. Most of her potions have various erotic effects and she's always looking for new people to test them. Once she's got a willing test subject, she'll try to keep them around to document all possible effects of the potion in question. 

Hexy is also a big bottom. While she might at first act confident or seductive to get people to wanna help her out, the moment the other person takes charge (due to the potion or otherwise), then she immediately feels weak and aroused. She's very into size difference and would love to just get picked up and 'played' with by someone way bigger than her. If someone is very forward with her then she will fluster easily and start to not so subtly hint at things she'd want to do together.
