As you may be able to infer from the title, or perhaps not, I am looking to explore the kink of heat. I have done it in the past, but haven't had much chance to really experiment with it, and see how fun it can be. I have no specific ideas for what to do, but I do have basic ones.
I was thinking that the heat could happen because of one of two reasons(feel free to suggest your own though as I am very open to ideas). In all of these, I want the heat to occur at the most worst times it possibly could. This means they will mainly be having sex in public, but we can have it when they are alone as well
1.) It is just a natural heat because your character is a neko or inu.
2.) Perhaps your human female character has a scientist for a husband, and he convinces you to drink a drug of his that replaces your monthly period with a form of heat that makes you crave sex at random, and won't be satisfied until they have sex.
2b.) Same as above, but your character drinks it by herself on accident.
