Demonic Urges - Sayori (Patreon)

Making a deal with the Devil is never a good idea… usually. But some people would do anything to fulfil their desires, even if it means that the rest of their life is filled with demonic lust and pleasure. Sayori never really looked into the “bad side” of the deal and only focused on the good. A few cup sizes up couldn’t hurt, right? It’s not like she was asking for unlimited money or living forever, just a slightly bigger bust. She got what she wanted… but the otherworldly forces decided that she would fare much better as a lust filled, cow succubus; which uses the man’s/woman’s “spirit energy” (wink wink) to give the succubus more power (or in this case, to gain bigger breasts). The milk from said succubus can turn any mortal into an incubus/succubus, which enhances their physical attributes (Men become more muscular, increased stamina, bigger penis, larger testes and sperm productoon goes through the roof. Women become more curvy, their no-no place becomes more adaptable; being able to take certain sizes that could severely damage a mortal and can carry more children. Futa is a mix of these traits) 

After y/n hears all the commotion coming from her room, you gently open the door… and are greeted by Sayori, only this time she’s almost pinned to the ground by the weight of her breasts. You try to fight your urges but damn, they are bigger than her torso…
