Simon sat on the stairs drained but watching in rapt fascination as Sophia licked her lips in anticipation of meeting her master's wife. The succubus slowly fondled her breasts and ran her hands over her stomach as she watched the front door. She rocked from side to side softly, like a serpent eyeing its next meal.
The sorcerer wrinkled his nose as a pungent smell wafted to his nostrils. At first he had no idea what the aroma was. It wasn't unpleasant, far from it, it was a ripe musky odor and there seemed to be some sort of exotic spice mingled in with the animal scent. It was simply the potency and suddenness with which the smell had assaulted him. Realization crept over him. It was her. Sophia was giving off some sort of pheromone. The proof to his guess came when his softened penis began to stir once more, rising to attention as the succubus emitted her most potent weapon into the air.
"Sophia, why didn't you...?" Simon began, but stopped short as the sex demon began to change before his eyes.
Sophia's skin began to change, her pale and luscious flesh becoming a dark indigo and leathery, batlike wings sprouted from her back along with a sinuous tail curving from the base of her spine. Simon found himself rubbing his eyes, unsure of what was happening to the buxom redhead that had just given him one of the best orgasms of his life. When he opened his eyes once again, the blue-skinned creature was nowhere to be found. Where previously there had stood a tall, curvaceous beauty with long, smooth legs and flashing green eyes, now Simon beheld a slim but muscular man in his late twenties with shoulder-length hair the color of midnight and eyes to match. The semi-hard flesh dangling between the demon's muscular legs was most impressive, but what struck Simon was the memory of the form the demon had taken between female and male.
The succubus, now incubus, reached down and began stroking his stiffening cock as the sound of a key turning in the lock ratcheted throughout the quiet house. Just as the door began to swing open, the demon turned to Simon. "I didn't need to use the scent on you, Master," the demon spoke in a deep, silky voice, "I was bound by your working. Now, watch closely, I might teach you a thing or two."
The incubus gave the wide-eyed magus a lusty wink before striding smoothly across the carpet to where Simon's wife, Mary was just setting her suitcase down beside the door. She had yet to catch sight of the naked, muscular man advancing upon her, but she had caught a whiff of the pheromones, her nose wrinkling a bit before a small smile spread across her face. The smile quickly faded as the demon came into view.
Simon guessed the pheromones had some sort of euphoric quality, as Mary didn't scream at the sight of the intruder into her home. Instead, she covered her mouth with her hand and took a step back, her eyes flickering back and forth between the handsome man's somewhat feral expression and the large member standing proudly from his belly.
"Who---who are you? How did you get in my house?" Mary asked quaveringly, taking another step back. Simon thought he noted a tone of something...lust?...underneath the confusion and fear.
"Shhh..." the demon said, holding a long finger to her lips and closing the gap between them. "Your husband has sent me to you. There is nothing to worry about." The finger slid down Mary's lips to her throat and continued down past the hollow of her throat to the top of her blouse. With a quick motion, he flicked his hand and her top opened wider by a few inches. Simon saw the button fly past him and roll into the kitchen.
Mary gave a stifled yelp, her eyes searching the coal-black orbs of the man before her, looking for more answers, but they were not coming. The demon flicked its wrist second time, a third, again and again, and Mary could do nothing but watch as this complete stranger slowly removed the thin barrier of clothing that separated her naked flesh from his.
From his vantage point on the shadow-covered stairs, Simon gazed on as his wife began to give herself over to the situation. Watching in fascination, he began slowly stroking himself as he watched the play being acted out in his living room.
As the incubus began to slide her blouse over her shoulders, Mary started to raise her hands in protest, but a simple stern look from the intruder's dark eyes was all it took for her to acquiesce and lower her hands to her side. A flush of crimson spread across her face at the mix of emotions she felt cascading through her body. On one hand, the idea of being taken by the beautiful, dark-haired stranger filled her with an ache she hadn't felt for a long, long time. On the other, she hadn't made love to another man in the eleven years she had married to Simon.
