Kinkfinity/Sexually Transmitted Enchantments
From Create Your Own Story
This universe's STDs. They're sexually transmitted, but not bad or any sort of damper on things. They were developed by an elf centuries ago, and spread by giving them to her succubus friend. Demons are immune to these but can carry and spread them. Most of them have names that directly disclose their effects.
STEs
Hypersensitivity
As the name suggests, Hypersensitivity sends sensitivity through the roof. To the point at which simply brushing your dick or pussy against something will give an intense orgasm. Thankfully, its effects do tone down after a while, but it still makes an orgasm very easy to achieve. But the couple days to couple weeks at which it's at its strongest are some of the most intense days of your life.
Hyperproductivity
Slightly less obvious, Hyperproductivity sends production of semen, eggs, and vaginal fluids through the roof. It has minimal effect on sensitivity, but it also amps up sex drive. Unlike Hypersensitivity, its effects don't change in magnitude over time. Getting even slightly horny will lead to big puddles of fluids.
