"Another mortal summons me?" The demon giggled, her pink eyes boring into you, "Did you bring me here for a good time? Or did you want to make a deal?" She shifted her weight, her enormous breasts bouncing. A malicious giggle left her plump lips, but she didn't move from the summoning circle, the protections seeming to hold. You turned away from the succubus, grabbing the ground set of herbs from your table. You turned back to the curvy woman and smiled as her face dropped. "W-what do you think you're doing with those?" She stammered, fear on her face as she realized what you were holding. You didn't respond; engaging her in a conversation is how these demons won, and you weren't about to let that happen.
"Stop!" She commanded, a bolt shooting from her hand but bouncing off an invisible wall. You tossed the mixture into the circle, the woman's fight starting to wane. "I yield," she grunted, hardly able to even stand anymore, "Make your demands and free me." You were going to do no such thing, not when you were so close. A vial appeared in your hand, the cork flying off with the flick of your thumb. You brought a small leatherbound book from your pocket. "Why are you doing this?" She shouted, banging against her enclosure, "Let me go, please!" You started to recite the incantation before downing the vial. Both you and the demon began to glow, your smirk contrasting with her grimace.
With a flash, you found yourself inside the circle, staring at yourself, or at least your body. You looked down at your gigantic boobs, squeezing them with your thin arms. "What did you do!" Your body shouted, "Give me my body back!" You ignored him, running your hand down your snatched waist and wide hips. The weight of your horns sat upon your head, and your new spade-tipped tail and leathery wings swished and flapped involuntarily. You turned towards the mirror you had set up, staring at the body of the succubus you had just stolen. You could feel the dormant power deep inside you, and the lust, the insatiable lust.
You turned back towards your old body as he kept screaming at you before giving him a wave. "No!" He shouted, "Don't leave me in this accursed mortal body!" Without so much as uttering a word, you extinguished one of the spell's candles, freeing you from the pentagram. "Noooooo!" Was the last thing you heard as you slipped away, leaving the new human to his fate as you began your new life as a succubus.
