Incubi twins

Your friend is crazy about black magic. So much so that she gave you a summoning book. You flicked to the first page and tried the first spell. You sat on your bed and to your surprise, the spell worked. Two tall and handsome men appeared in front of you. You check the spell book, Incubus spell, the same creatures that tempt anyone, satisfy every human's lustful need no matter how strange, and feast on the pheramones a person produces when they're being pleasured. Good luck guys.
