A good student

"Are you ok Ma'am ?"

The buxom teacher didn't answer immediately. Her eyes had a hazy look in them, when she finally answered Mark's question, it was with a vague groan. Mark was looking worried but he knew why his math teacher acted strange. Since the beginning of the class, Mark was releasing pheromones each time the teacher was close.

And it happened a lot of time since he was sitting on the first row near her desk. Of course the other students were affected too, a few pants felt tight with painfully erect cocks while the girls tried to understand why their pussies were suddenly so wet. A few students started to act strange, a chubby teen blushed when she realized that she was sucking the tip of her pen rather erotically while a boy almost came in his pants when he catch a glimpse of his teacher's gorgeous cleavage.

Alexis Garcia didn't know what was happening, it was her last class for today and she felt incredibly aroused. Her nipples her hard like diamonds and her panties were soaked. She also felt attracted to one of her student, which was abnormal, she was happily married and had a kid for god's sake ! but Mark looked so sexy and so powerful ?

So when he asked her for tutoring lessons after class, she gladly accepted.

Behind the counter, Lydia moaned with delight. Work had never been so boring but luckily she had some distractions. She had transformed her underpants by adding a few improvements to them. A big dildo was currently deep in her pussy, its vibrations were giving her small orgasms regularly. She also had a vibrating butt plug in her hungy ass. Her boss, Mr. Graham and some customers had given her a few suspicious looks but she didn't care. As soon as the store will close, she will give her boss a nice gift. She couldn't wait !

"Oh god make me cum ! lick me, fuck me, anything ! just make me cum !"

Alexis Garcia was mad with pleasure and frustration. The tutoring had quickly degenerated into a seduction game, then into a fuckfest. The empty classroom was filled with moans and pheromones. Alexis had already swallowed 2 loads of cum, which left her craving for more. Meanwhile Mark had licked and fingered her wet pussy four times, but he refused to let her cum.

"I told you, Mrs. Garcia." Mark pulled his face away from the latina's hot sex. "You don't get any more until you give me what I want."

"I'm all yours, body and soul Please, stop teasing me. I need to cum now ! I'm losing my mind "

"Then give me everything. Your husband, your son, your soul "

Mark teased her clit for emphasis. Alexis cried but agreed. Mark finally gave her a long deserved orgasm, the stronger of her life. So strong it made her soul came loose from her body.

"Let's go to your place, I have a lot of things to teach you" Mark said with a grin.

"But my son will be at home in thirty minutes, we can't ? Aaaahh"

Mark silenced her with a twist on her nipple, the busty teacher didn't object anymore, fully entranced by the incredible stud who had seduced her.

The teenage boy had come home finding her mom on her hands and knees desperately sucking a guy, her ass facing the door. Alexis hadn't noticed her son's return but the boy had smiled at him while showing him his mother's well fucked ass. Hypnotized by the show in front of him, his lungs full already full of pheromones, the boy hadn't hesitated much. Alexis's concerns were quickly drowned by a mouthful of black cum and she finally succumbed.

Looking up to her mother, Juan watched her brown eyes contract and twitch. The irises stretched into long, snake-like pupils. The brown color surged into a bloody red, as her soul was sent into the depths of Hell.

The transforming teacher's already substantial breasts ballooned out in front of her, showing no hint of sag as their heavy weight was suspended proudly by her shoulders. Her widening hips and lush ass inflated the rest of her delectable hourglass figure, casting her body in the mold of the ultimate seductress. It matched her twisted mind perfectly. Alexis's growing tail slipped down between their grinding bodies, wrapping around Mark's tensed thighs. The demoness hissed for more as her black horns extended from her wild ebony locks.

Juan watched her mother as she finished her transformation. His dick was still erect despite his previous orgasms. His emotions were a mix of fear and intense arousal. Her mother rised from his crotch and stared at his shivering from, all the love she had in her eyes were gone, replaced with lust.

"Time to finish your education, son" she said as Mark allowed her to move toward Juan.

Lydia moaned as she mashed her boobs on her boss's chest. Mr. Graham latched onto her mouth and thrust his forked tongue between her fangs.

The crimson harlot sucked at his tongue eagerly, finally aligning his 15 inches cock with her tight little cunt and rocking back onto his rod. Her pussy walls grabbed his length, massaging him as he hilted inside her.

Lydia pulled away from his probing tongue, snarling in delight as his massive dick sawed in and out of her. Her tongue trailed between her fangs, still locked with her boss in a battle for dominance.

The old man increased the speed of his thrusts as his body adapted to the demonic power growing within him, adorning his much larger frame with more muscle than he would have dreamed of in his former life. He bellowed, baring his deadly fangs to the world. Her lover caressed his bulging forehead with her claws, adoring the masculine angles of his youthening face. He could felt his bones moving as his tail and wings emerged.

The new demon slipped his claws into Lydia's spasming asshole. The she-devil shrieked as her lover's talons sank into her one by one. Her passionate moans continued as her eyes hooded in euphoric bliss. As her former boss's giant fist disappeared between her luscious buttocks, Lydia's holes grasped at the demon's penetrating appendages, thrilling as they invaded her more and more deeply. She massaged her enormous crimson tits with her wicked claws, plumping them as she gyrated on the demon's massive cock. Massive orgasms were surging through their hellish bodies.

« You know Sir, I think our work will be even better now » Lydia breather between shrieks of pleasure. Jonathan Graham answered with a smile before he silenced her with his new tail, blasting a load of black spunk into her hungry throat.

Alexis rode hard on Juan's massive dick, milking at it with her cunt as he roared and snarled beneath her. Her claws dug into his chest as she pressed her enormous rack together with her elbows. She let her tongue clean up the black cum that coated her cleavage from the last round of sexplay, where the young incubus had fucked her melons with both his cock and tail while she sucked off Mark.

The demonic mother bounced hard on her son, coaxing another load of cum into her tight pussy. Then she looked over her shoulder at her corruptor, raising her tail high into the air and waving her inviting ass at him.

Mark grinned, prowling over to the wanton demoness and climbing on her back. He gripped her waist with rough, taloned hands as he rammed his impossible length into her tiny asshole. Alexis howled with pleasure, baring her sharp fangs. The duo of incubus continued to pump into the howling succubus, forcing more and more of their cocks into her otherwordly holes. Turning her face to her unholy student, Alexis lapped at his fang-filled mouth with her long tongue. The slut purred into his mouth, gnashing her fangs against his as the mating grew more and more bestial.

She humped her hips wildly, grasping the thrusting members with the muscles in her pussy and ass. Mark bit into the back of her neck, forcing her horned head down and mashing her colossal boob into Juan's hungry mouth.

Finally, the duo felt their orgasms coming. They suddenly inserted their tails into Alexis cunt and ass alongside their cocks, sending torrents of black jism into her insatiable holes.

His job done, Mark morphed into his human form, leaving the corrupted mother and son behind. The incestuous couple were having a dialogue about the continuation of the events. Alexis couldn't wait to share her gift with her husband tonight. Meanwhile Juan planned to corrupt her girlfriend and her friends. This conversation quickly degenerated into another fuckfest as they moved into a 69, trying to calm their never-ending lust for each other.

Mark smiled and headed back to his own house, he still had some work to do.
