No chance

Trevor's heart was racing in his chest as he ran for the exit. He wasn't sure what had happened to Ms Baker but seeing her changed like that right in front of him was unnerving to say the least as he approached the first exit.

"What the...... what the fuck is this locked?" He said as the fire exit door was locked.

"Uh oh, someone can't get out," Ms Baker's voice said over the speakers, taunting him. "Only the main exit is unlocked, but now the countdown begins. 5......"

"What the.... how the fuck did she get to the office so quickly?"

"You swore again. Bad boy, now I have to skip to 3," she said as he started running again as fast as he could, seeing the main entrance just down the hall. "2," she said before she chuckled a little while Trevor felt like he was in a horror movie. "So close, Trevor. Almost there. You know, I'm starting to wonder if you even want to escape, before I say....." Trevor reached for the door, knowing his freedom was in his grasp before he felt a hand on his shoulder stopping him dead in his tracks. "1"

Trevor was yanked back and thrown to the floor with a hard thud. As he looked up, he saw his teacher, or at least the woman who used to be his teacher standing between him and the exit, her eyes glowing bright red as her ears were now pointed. She had two small horns on her head as her hair hung down.

"That was fun. I love the thrill of the hunt, but you didn't make it," she said as she walked over to him, sliding off her heels. "Poor little Trevor," she added before she began to rub his crotch with her foot. "Oh my, perhaps I was wrong for using the word little," she said with a grin a she bit her lip.

"Ms Baker, what are you doing? What's happening to you?"

"Honestly, I have no fucking clue! Oops, I used bad language. Guess I owe you a second." She chuckled at what she had just said as she continued to massage his crotch with her foot. "All I know is I am going to fuck you, Trevor. I am going to fuck you so hard, right here on the floor of your high school. And if you do a good job, then I'll give you your passing grade," she said as she grabbed her shirt and ripped it open before he bra broke, letting her tits free. "Look at my new body. Don't I look so fucking sexy?"

"Holy shit," he said as he gently tried to back away, both aroused and scared as his teacher continued to strip, showing off her new sexy form.

Despite the horns, clawed fingers, fangs, and tail, Trevor couldn't help but want her to fuck him just like she said she would. He knew deep down that his life was in danger; he could feel it in his gut. Still, his cock was throbbing in his pants, and he knew he wasn't going to be able to resist her, and whatever she wanted to do to him.

"Oh God, this feels so good!" She said, screaming, so her voice echoed through the empty school. "Now, my prize," she said as she glared down at him.

"Ms Baker, I..... oh shit!" He said as his belt began to unbuckle all by itself before his pants unzipped and slid down around his ankles. "Oh fuck..... what.... what's happening?" He asked before his underwear soon followed, letting his erect penis out to the open air.

"Oh my, there it is," Ms Baker said as she got down on her knees and began to crawl towards him.

Trevor's eyes widened as his cock seemed to try and bend towards her like it was reaching for her. It felt strange and unnatural but also good at the same time as his foreskin gently slid up, like his cock was ready to jerk itself off to make her happy.

"He's excited, he knows what I can do to him," she said as she stuck out her tongue which was long and lanced down the middle. She slid it up the underside of his shaft, before tasting a small dribble of precum that had come out of him. "Yes, oh yes, you taste so good."

"I...... I..... Ms......"

"Call me Annabelle," she said with a sickening smile before she engulfed his cock with her lips.

"HOLY FUCK!" He cried out as she began to suck his cock with a **** that didn't feel human, making him buck his hips as her tongue coiled around his penis. "Annabelle, holy shit........ HOLY SHIT!"

"I like it when you say my name. I like seeing you scared and ****. I'm starting to think you failed my class, so you could spend the summer with me."

"I....... I uh," he said, confused, and she just teased his cock with her tongue.

"You've wanted to fuck me for years, haven't you? I see the way you've looked at me. Maybe that's why I'm such a naughty girl now," she continued to say as she looked like a devil covered in sweat. "You want to feel my pussy, don't you? You to watch your cock disappear into my moistened slit."

"Oh God, Ms Bak...... I mean, Annabelle, this isn't you."

"Then who else could it be?" She said before she climbed into his lap and slid closer letting his cock get within inches of her pussy. "I feel like me, and pretty soon, you're gonna feel a lot of me," she said as she shoved her fingers in her slit and spread the lips apart. "You want this, so fucking bad, and I'm gonna let you," she said before she grabbed his shirt and ripped it off of him.

Trevor just lay there with his mouth open unable to articulate the words. His cock was throbbing as it bent towards her again, like it had a mind of its own, begging to go inside her. His teacher had become this sexy demoness and he was helpless to resist her as she lifted her pelvis, leaving some of her fluids on his thighs before hovering above his cock. His cock reached up, pulsing with anticipation as she hovered above him, moving her hips a little before finally lowering herself onto his manhood.

"OH FUCK!" He cried out as he grabbed her waist.

"You're all mine now," she said before she leaned down and licked his face.
