A romantic comedy based off the ancestors of the Demon King, who wanted to take over the world, and the Hero, who put a stop to those plans. They don't have powers, but they have a shared erogenous zone that proves they're the descendants chosen to repeat history. They turn nearly everything into a competition to "win" and decide who is the glorious victor, while the Hero courts the demon king. *Pretty Hot Stuff ;)*
A case where some humans become either half or fully transformed into an animal. In this case, the seme becomes a large dragon who falls in love with a high school student who has no family, therefore, they become each others' family.
Seme drinks a cure for a rare disease and it lives inside his fluids, therefore, he fucks the seme, and others, to transmit the vaccine into their bodies. Pretty stupid situation, but very hot and funny. The couple is sweet together, though the seme is a playboy which hurts the uke until he settles with him
Seme is sensitive to scents and likes the scent of the uke's body, aka his phermones. They must be phermones bc many animals are atracted to him by his scent and having sex with the seme increases the attraction of animals to him.
Few ppl have the gene that makes them morph into half animal with ears, tail and instincts. There's dim genes which mean the person will for sure morph anf sub genes, which means it's possible for the person to morph, but it's not likely (like 1% chance or smtg)
Taiga, an heir to a gang, has the ability to get pregnant and has heats. It's like a touch of omegaverse with Taiga's body, but there's no alphas and/or a way to tie ppl together. There's no biological reason for someone trying to have sex other than an interest or curiosity.
