Professionally

... Mrs. Anderson. He looked up using her eyes, seeing Mr. Phillips shaking his head slightly as he walked to the door and presumably to his class. Matt stood up, the weight distribution of the body he was in throwing him off momentarily before he straightened up, walking toward the lounge door in the flat heeled shoes that had replaced her previously high heels. Even those had been replaced in the change between Miss Rathaway and Mrs. Anderson. Matt shook her head, running her fingers through her long, blonde hair, and walked to her classroom. He was tempted to walk her down to the women's bathroom and explore the body he had lusted after since the first time he had stepped into her classroom - at least until she had gotten married, but the plan he had in mind would give him the opportunity to explore her body.

She opened the door, and Matt saw the students sitting quietly, most with their calculus books open. A few of the students he knew as a bit slower than the others (not much slower, of course, since this was an advanced class) were still working on the homework Mrs. Anderson had assigned the day before. "Pencil's down, people," Matt said in Mrs. Anderson's voice. "Books away, too. Today is going to be a - special class."

There was some mumbling as the class did as she asked, but Matt could hear most of the mumbling was curious, and no one had a chance of guessing what this was about. Matt didn't think he had ever heard of a calculus class that was taught without books, so the confusion was understandable. Once she had the entire class' attention, she walked in front of her desk, turning her back to the class and reaching out, moving everything from the center of the desk to the edges. Without turning, he started unbuttoning her sweater vest, laying it carefully in the center of the desk before turning around.

"Today's lesson is going to be a special one," she said, her hands going to the buttons on her shirt. Several of the students mouths dropped open as one button followed another, first exposing the exquisitely modest bra, then down to the waistline of her skirt. Matt pulled the bottom of the shirt out of the waistline, unbuttoning the last few buttons before sliding the sleeves off. Without turning, she lay the shirt behind her on top of the vest. Half the class were now looking at her bra covered breasts with lust, the other half with embarrassment. "Who here knows the sum of 1 and 1?" she asked, running a finger over the cup of her bra.

Several guys (and one girl) shouted "Two!" almost immediately, and Matt smiled with Mrs. Anderson's lips. "Very good," she murmured, reaching back with both hands to the clasp of her bra. Matt thought it might be difficult to undo the bra from this angle, since he had never worn a bra before, but the knowledge was in Mrs. Anderson's brain, and Matt accessed it easily. She slid the bra down her arms and off, depositing it on the desktop as well. She had the attention of all the students in the room now.

"Now, who can tell me what the difference between five and three is?"

This time, there were only two students that answered - one guy at the back of the class and the same girl who had answered before. "That's correct," she smiled, her thumbs hooking underneath the fabric of both skirt and the panties underneath. "Now, what's seventeen times one?" she asked, pushing the fabric down, letting gravity take over, the skirt and panties landing on the floor around her ankles.

Only one person, the same girl, answered. "Seventeen," she said quietly, getting to her feet. Matt recognized her now - it was Susan Brent, a quiet, shy girl who was constantly mocked by the cheerleaders and jocks alike. Matt smiled, turning her back on the class and bending down, picking up the skirt and panties and laying them neatly over the other clothes. She heard movement behind her, and when she turned back around, all but two of the guys were also on their feet. Matt sat on the edge of the desk, looking at Susan. "You got it right, why don't you come to the front of the class?" she purred. "You did get the right answer."

The girl walked up to the teacher's desk and between Mrs. Anderson's legs as she spread them so the whole class could see the neatly trimmed hair just over the opening of her pussy. "You seem like a girl who knows knows what she likes," Matt purred. The eighteen year old nodded, kneeling in front of her. Matt reached down and ran her fingers through the girl's mousy brown hair, pulling her face against her flesh. Susan instantly started licking her pussy, running her tongue up and down the slit with an expertise Matt hadn't suspected. Apparently Susan had an education in eating pussy.

Matt kept watching as she kept licking until the orgasm raced through Mrs. Anderson's body. As she came, she looked up and realized every male was on their feet, and all of them had pulled their cocks out, and all were stroking. "Sue, honey, why don't you let the boys have a bit of fun," she murmured, petting her head. She pulled back, shyly getting to her feet and stepped aside, and one of the guys stepped forward, his cock dripping precum.

"I... I don't have a co... condom," he stuttered, still approaching, his dripping cock head inches from her saliva drenched pussy.

"That's okay," Matt said, spreading her legs wide. "It's safe." Of course it wasn't. Matt could tell by the thoughts in Mrs. Anderson's mind that this was absolutely not true, her body at an almost perfect time to get pregnant. Without hesitation, however, the teen stepped up and penetrated his teacher's pussy with one hard thrust. Matt lay back on the desk, her back cushioned by the clothing as the student started thrusting hard, gripping her hips in his desperation to get as deep into her as he could. Five thrusts was all it took, and he started cumming deep inside her.

"Hey, man, it's my turn," a voice said, and the first of the seventeen male students in the class was moved aside only to be replaced by another, one who stepped up and shoved his way into her pussy. He wasn't as gentle as the first, but it still didn't take long before he was filling her with sperm. Student after student, every one with above average intelligence but every one with the same basic urge to mate. By the time the principal found them, brought by one of the female students, fourteen of the seventeen guys had squirted sperm into her fertile womb. Although Matt had no way to know it, all but three had willingly given their virginity to their sexy teacher.

Laughing to himself, Matt jumped back into his own body, currently in his own math class just a few doors down. They could all hear the commotion out in the hall, and none of them could concentrate on their tests over the racket. Matt smiled, knowing that even if the school kept quiet that Mrs. Anderson had slept her way through her honors calculus class, they couldn't let her keep teaching. She may be able to keep her marriage in tact, unless one of the students managed to knock her up.

Leaning over his test, he checked his work and found the auto pilot that seemed to work in his absence did pretty good work. What to do next...
