When Mia walked into the room with that tiny skirt on and her luscious breasts all but bursting out of her top, Evan immediately sat up and took notice. As did his cock.

Damn, she’d never looked so hot. Why hadn’t he ever thought to give her a sexy outfit to wear before? Before class had even begun, Evan was ready to move on to the advanced lesson and take her into the coat room.

But before he had a chance to tell Mia how freakin’ awesome she looked, the instructor, whom up until that point, had been sitting quietly behind a desk, stood up and strode over to the door.

“Ms. Wallace,” the instructor said. “You’re late.” He wasn’t an imposing man—fairly average, really. In fact, Evan expected a sex school instructor to look different, maybe like something out of one of the porn movies he’d seen. But this teacher looked like just a regular guy. There was something in his voice, though, that demanded respect. And even from where Evan was sitting, he could see the uncertainty cross Mia’s face.

“I’m sorry, Mr....”

“My name is Dex. But you will address me as Professor.” The man’s voice reverberated around the room. “And lateness will not be tolerated, Ms. Wallace. You’ve kept the class waiting. Do you have an explanation for everyone?”

Evan watched Mia’s gaze travel over the rest of the group, much like he’d done when he’d arrived. There were three other couples in the room. They were all about the same age, somewhere in their late twenties to thirties, Evan figured. And for whatever reason, that made him feel better. At least he and Mia weren’t the only young couple who were looking for a little spice in the bedroom.

“Well, Ms. Wallace?” the professor said. He didn’t take his eyes off her and the intensity he was staring at Evan’s wife with made Evan squirm in his seat. Also, the fact that he kept referring to Mia as “Ms.” upset him. She was his, dammit. Ms. implied she was available. And she most certainly was not.

“I...I was...” Mia stumbled over her words. A blush colored her almost exposed breasts, making her look every bit the chastised school girl. Evan had never seen her so unsure. She was one of the most confident women he’d ever met. Always in charge and in control of the situation.

“I was getting changed,” Mia said finally.

The professor took a step back and looked her up and down, with a lingering gaze that again made Evan want to jump out of his seat and grab his woman. But something kept him in place. He was curious to see how the scene in front of him would play out.

“It looks like you missed a piece,” the professor said. He took a ruler off his desk and using it, he lifted the hem of Mia’s already indecently short skirt, so her freshly waxed pussy was clearly visible.

Evan’s cock hardened and strained against the jeans he wore. He should have been incensed by the way this other man was exposing his wife to a room full of strangers, but he’d never before been so turned on.

Mia’s skin flushed and Evan could see her tremble, but she didn’t lower her skirt.

“There were no panties in my locker, Professor,” she said. “I’m sorry.”

The professor pulled his ruler away and turned, walking slowly across the room, smacking it against his palm as he went. “So, you’ve not only made the entire class wait for you, but you’re not even properly clothed. Is that right, Ms. Wallace?”

Mia didn’t say anything. For the first time, she glanced at Evan and pleaded with her eyes for him to help her out.

Evan hesitated, but only for a second. His desire to see how the instructor would handle the situation was strong, but he couldn’t ignore Mia.

“Professor,” Evan said as he rose from his seat. “I’m sure Mia didn’t mean to be late. It’s the first day and all, and panties or not, she looks pretty great.”

The instructor spun around on his heel and smacked the ruler down on the desk. The sound reverberated through the room. “Mr. Wallace, I don’t believe anyone addressed you.”

Feeling properly chastised, Evan moved to sit down, but then had a change of heart. “Professor, Mia is my wife and—”

“I’m aware of who she is, Mr. Wallace.” The instructor took two steps towards Mia, who trembled but held her ground. “Sit down so I can finish this and begin the lesson,” he said to Evan.

Surprising even himself, Evan did as he was told, more eager than ever to see how it would play out.

* * *

When Evan had stood up in defense of her, Mia felt a flutter of excitement that her man would defend her. To be honest, she was already pretty excited and had to fight the urge to rub her legs together to ease the building pressure in her crotch. The professor was an intimidating instructor and not normally her type, but the way he commanded the room, and especially her, was making her wet.

She watched while he addressed Evan and with a lingering look, her husband returned to his seat. She could tell he was just as interested to see what the instructor would do to her as she was.

Mia waited for what seemed like forever, while the professor paced across the room and back again, all the while tapping his ruler against his muscular thigh.

When he opened his mouth to speak, Mia’s stomach contracted, and for a brief moment, she thought she might come right there on the spot.

“Bend over, Ms. Wallace,” Dex said. “When you don’t listen, there are consequences.”

Bend over?

Mia’s mind raced. He couldn’t really mean he was going to strike her with that ruler? Surely not. Had she agreed to corporal punishment?

Her heart quickened with the realization that she, in fact, had agreed. It was part of the questionnaire, and while Mia and Evan had never experimented with bondage or spanking before, the idea excited her.

Judging by the slick between her legs, it more than excited her.

Mia did as she was told and bent over, exposing her bare ass to the classroom full of strangers.

There was a murmur of approval that rippled through the class and Mia was pretty sure she could pick out Evan’s groan of approval. Or was it something else?

The instructor ignored her, and her bare ass, and continued to address the class. “Ms. Wallace has done a fabulous job demonstrating your first lesson. Can anyone tell me what it is?”

The absurdity of the fact that he would be addressing a room full of adults as if they were regular students, while she had her ass in the air, fully exposed, was not lost on Mia.

She couldn’t see who raised her hand, but he called on someone who’d obviously been paying attention. “You have to follow instructions,” the unseen woman said.

“That’s right,” Dex agreed. “Can you tell me why that’s important?”

The star pupil, who was quickly becoming the teacher’s pet, piped up again, “If you can’t follow instructions, you won’t be able to please your partner.”

“That’s exactly right.”

There was a whooshing sound and the ruler landed with a small smack on her bare ass cheek.

Mia jumped and a flood of heat flowed to her center. She had to resist the incredibly intense urge to squirm and relive some of the pressure in her crotch.

The professor continued speaking as if nothing had happened. “I’m sure everyone in this room has said something to the effect of, ‘Tell me what you want?’ or ‘What feels good?’ to their partner. Am I right?”

Mia craned her head to see the class, who were all nodding and agreeing with their teacher. Even Evan, whose gaze was fixed squarely on her ass, was nodding his assent.

“How can you expect to please your partner when he or she does, in fact, tell you what they want, when you aren’t listening?” he said. “The fact is, most people ask because that’s what’s expected of them, but they’re too preoccupied with themselves to listen to the answer. And if you aren’t paying attention, you won’t be able to please your partner.”

Mia was intent on watching Evan, so she missed it when the professor once again came closer and with a swift flick of his wrist, brought the ruler down squarely across both ass cheeks.

Mia jumped and couldn’t restrain her yelp of pain and the tear that sprang to her eyes, accompanied by the intense heat that unfurled in her core. But still, she didn’t stand until she was given the instruction. “You may rise, Ms. Wallace.”

When she straightened, there was an unmistakable gush of wetness between her legs that slipped down her thigh and Mia distinctly noticed the absence of her panties.
