When Brian’s Latin class found out that their usual teacher was out sick and that a substitute would be coming in, they were all excited to see who it would be. So when they all walked in and saw Miss Phillips standing in front of the blackboard, a hot, incredibly busty substitute teacher that the entire school had a crush on, they were all instantly paying attention. Rumors talked of students that had managed to seduce her, or watched her get changed in the locker room, but Brian didn’t believe a word of it. Miss Phillips, despite having breasts the size of cantaloupes smuggled into her shirt, took her job too seriously for that... surely?

Brian was revising by whispering his Latin phrases, although he kept stumbling over his words. He just couldn’t get one sentence right and was repeating it when suddenly there was a flash of light and a small, chubby red devil was sitting on his desk. Looking around in shock and seeing that his classmates hadn’t even noticed anything out of the ordinary, the devil explained that only the one who summoned him could see them. Sounding annoyed, the devil offered his captor a small wish in return for being released back to his home in Hell. Looking up at the front of the class and seeing his substitute teacher working quietly, her enormous bust resting on her desk, Brian knew exactly what (or who) he wanted. Wishing that he could make Miss Phillips do whatever he wanted, the devil got a mischievous glint in its eyes and snapped its fingers, vanishing in the blink of an eye.

When nothing seemed to have changed by the end of the day Brian began thinking that the encounter had been a part of some elaborate daydream, but when he woke up the next morning in an unknown apartment he knew something must have happened. Sitting up his vision was too blurry, but he could feel that his body had changed. Noticing his smaller, softer hands he began exploring his body, feeling unfamiliar curves, a hefty weight on his chest and a strange absence between his legs. Finally fishing a pair of glasses from a bedside table, he saw that he had been placed in the body of his sexy teacher! The devil had tricked him, and he (now she) was Miss Phillips!

Unable to find her phone and wanting to look for help, her first thought was to head to school and explain what had happened to her old friends, but as she stood up she felt her weighty breasts throw off her balance. Curious, she unhooked her bra and began to squeeze her impressive bare titties, fingers brushing against her nipples and sending a shock of pleasure through her body. Standing in front of the mirror and taking her panties off she masturbated to her reflection for the first time as a woman, one hand teasing a teat as the other rubbed her clit until eventually she came and fell into an exhausted pile on the floor.

Looking at her alarm clock as she waited for the warm glow to fade, she saw that school started in 15 minutes! Throwing on the first shirt and skirt she could find, she was out of the house and walking to school in a pair of uncomfortable heels when she realized too late that his clothes were way too small. Her shirt showed off a lot of skin between the buttons, chest straining the fabric around the torso, and her skirt finished halfway down her thigh which made it cling to her tight booty as she walked. Worse, she’d forgotten to put her underwear back on, meaning her hard nipples showed through her skirt, and even just a cool breeze wafting past her bare pussy would turn her on again.

When she finally arrived, class had just started. An annoyed-looking principal chided her for being late and directed her to a classroom where she would be filling in on teaching Sex Education to a bunch of loud, horny teenage boys. Instinct kicking in and not wanting to lose her job, she steeled herself for the first day of the rest of her life as a busty, lusty tutor. And it wouldn’t take long until she could confirm first-hand the rumors that Miss Phillips was a raging nymphomaniac having sex with students, too...
