Subbing for Her Teacher, Mr. Cain

Mandy watched Mr. Cain pace back and forth in front of the class as he lectured on statistics. When he glanced in her direction, she looked him in the eye, bit her lip and spread her legs a little wider.

She’d inched up the skirt of her uniform when she sat down in his classroom. She’d always had a thing for the strict math teacher. Now that she was eighteen, she pushed her teasing a little further.

Technically, he’d still see her as off limits since she was his student. She wondered if she could tempt him past that hurdle. The next time he looked at her, she ran her hand up the inside of her thigh.

Mr. Cain stuttered for a moment. His brows pinched together. He moved on with a frown and refused to look in her direction until the bell rang.

“Ms. Murphy,” his voice was like a whip.

Everyone paused in their scurry to gather their things and get out of the room.

“I’d like to see you in my office. Now.”

Other students looked at her with pity in their eyes. Mandy bit the inside of her cheek and looked down as if chastened. Her clit throbbed to the beat of her racing heart as she thought about being alone with him in his office.

Keeping her head down and her mouth closed, Mandy held her books to her chest as she followed Mr. Cain to his office.

He unlocked his office, opened the door and motioned her inside. She sat in the chair in front of his desk as the door shut with a quiet click. She held her breath as she listened for the lock to engage. It didn’t. Instead, Mr. Cain walked past her and sat at his desk.

He leaned forward, rested his elbows on his desk and steepled his hands as he looked at her. Mandy swallowed. She’d never had his undivided attention like that. His gaze was direct.

Her panties were damp. She shifted in her chair, but it gave her no relief.

“Would you like to tell me what that was all about, Ms. Murphy?”

“I know,” she said.

His eyebrows rose in surprise. “What is it that you know?”

“That you like discipline,” she said.

She hadn’t discovered anything specific, though she was sure she would if she went to his house. It was the way he held the ruler as he lectured. He tested the weight of it, slapped it against his palm, looked at it as if wondering how he could use it in other ways.

“Most teachers appreciate discipline in their classroom,” he said carefully.

“And outside the classroom?”

“I should have sent you to the principal’s office,” he said. “What you did has to stop. I can’t have all the girls in class — ”

“No one knows what I did except you and me. If you want to punish me, you can.”

“What?”

She bit her lip then said, “I need you to.”

He licked his lips. It was the first inkling she’d seen that he might be interested. “Why do you think you need discipline?”

“I crave it,” she said. “I’ve seen how you use the ruler, how you look at it.”

He didn’t respond.

“Please,” she whispered.

“I’m too old for you, Ms. Murphy.”

“I’m eighteen.”

“And yet still my student.”

“I’d like to be your student in other ways.”

“What ways?” His voice was low, gravelly.

“I want you to teach me about pleasure and pain.”

“And what do you know of pleasure and pain?”

“Nothing.”

“Nothing?” His brows pinched.

“Nothing.”

“Fuck,” he whispered.

And she knew she had him. She wasn’t technically lying. She knew a little from the porn she’d watched, but she had no real world experience.

“Lock the door, then bend over my desk,” he said.

“Yes, sir.”

Mandy stood from the chair. She hurried to flip the lock, then moved next to where he sat and bent over his desk.

He flicked her plaid skirt up and onto her lower back, then ran his hands over the backs of her thighs. Her eyelids fluttered with the ecstasy of his touch.

She barely registered him pulling away before she felt the first smack. Mandy gasped. She pressed her thighs together.

“Spread your legs.” He punctuated the command with another slap.

His voice was sharper, deeper than she’d ever heard. She couldn’t help but obey.

“Does this make you wet?”

“Yes, sir. I’ve been wet since we stepped into your office.”

The wheels of the office chair squeaked. Mandy looked over her shoulder to see Mr. Cain sliding off his chair to kneel behind her.

He yanked her panties down and off. He stuffed them into his pocket, then nudged her legs even farther apart.

The next swat came hard and unexpected. Mandy sucked in a breath. Because her panties were gone, a drop of her wetness cascaded down the inside of her thigh.

Mr. Cain caught it with his tongue and licked a path up to her opening. Silently she begged for him to give her more, to thrust inside her. She groaned when he pulled away.

“My rules, Ms. Murphy.”

“Yes, sir.” Her voice wavered.

She needed more. She spread her legs a fraction wider. The next slap was to her pussy. She cried out.

“Any more of that and this will be the last time I touch you,” he said low.

She nodded. “Yes, sir.”

“You get five for screaming.”

He smacked her five times in rapid succession. By the time he was done, she was panting.

He rubbed a hand over her hot skin.“Do you want more?”

“Yes, please,” she whispered.

“How far do you want to go with this, Ms. Murphy?”

“I’ll take all you’re willing to give, sir.”

She hoped that meant he’d fuck her. She tilted her hips back and forth, but could find no relief because her legs were spread.

“Good. Because we haven’t discussed your punishment for teasing me in the classroom. Turn around. Lay on the desk, thighs spread wide.”

Mandy scrambled up on the desk and opened her legs. When he looked her over, Mr. Cain licked his lips.

“Can you be quiet?”

“Yes, sir. I think I can. It’s better than I imagined, though.”

“You’ve been doing research?”

“Yes, sir.”

“You know the color scale? Green, yellow, red?”

“Yes, sir.”

“Red means…”

“Stop, sir.”

“This is what happens when you tease me.”

He slapped her pussy. It wasn’t anywhere as hard as he’d slapped her ass, but it was different. Both pleasure and pain so tightly intertwined she couldn’t tell one from the other. He waited one beat, then two. Her mind was a little fuzzy, so it took her a moment to figure out why he didn’t keep going.

“Green, sir,” she said.

Smack.

She gasped. She moaned.

Smack.

Mandy tilted her hips, though she wasn’t sure what she was trying to do.

Smack.

His erection pressed against her hip.

Smack.

“Please. More,” she begged.

Smack, smack, smack.

The last slap hit her clit. A bolt of lightning arced through her blood from her head to her toes. Her body arched off the desk until it was only her feet and the top of her head left to support her. Mr. Cain covered her mouth with her panties, muffling her scream.

As soon as her body once again lay on the desk, he removed his hand and turned away from her.

“Sir?”

“You screamed,” he said. “Quiet was my only condition. If we’re discovered, I’ll lose my job.”

“I tried not to. It was more than I ever imagined. Please.” She got off the desk, walked around until she was in front of him and got onto her knees. She bowed her head. “Please,” she whispered.

He cupped his hand under her chin and tilted her face up. His eyes blazed with lust. His chest rose and fell with rapid breaths.

“You know what I need,” he said. “Give me your mouth.”

She opened obediently.

“Take my cock out.”

Mandy smiled and did as she was told. This was the one thing she had experience in. It was how she’d kept boyfriends happy when they never got her hot enough to take off her clothes.

She pulled him out of his boxers and swallowed. His was by far the biggest cock she’d ever seen, but she was determined to please him. She licked the salty drops gathering at the slit, proud she’d been the one to turn him on.

She looked up into his eyes as she sucked on the tip, then pulled him into her mouth. She slowly worked her way down his shaft, preparing her throat.

Mr. Cain smoothed her hair away from her face. He cupped her cheeks as he spoke. “Not so innocent then? I’m going to fuck that sweet little mouth and you’re going to swallow everything I give you.”

Mandy nodded.

“Three taps on my thigh if you need me to pull out,” he said.

He didn’t wait for a response before flicking his hips forward. He groaned quietly.

On the third thrust, he cupped the back of her head and pressed in to the hilt. Her airway was blocked. She didn’t panic, she swallowed around him.

“Fuck,” he whispered as he pulled back to let her breathe. “So good. I have class in ten minutes. Get me off in less than eight.”

Mandy lunged forward until her nose pressed his pubic bone. Again she swallowed. Again he groaned. His erection throbbed against her tongue.

She reached up and cupped his balls, pressing small circles just behind them. He spread his legs to give her a little more room. She didn’t know if she’d be in trouble for taking the initiative, but she wanted to get him off before his class. The next time he pressed forward, Mandy hummed as she swallowed.

“Here it comes,” his hips made little micro-thrusts. “Swallow it all.”

The first spurt hit the back of her throat. She gagged a little, but that just made Mr. Cain hiss, “yes,” as jet after jet shot down her throat.

When he pulled back, he was panting, but still half hard.

They stared at each other in silence as his breaths evened out.

“You have a lot to learn,” he said. “It’s going to be a pleasure teaching you.”

Mandy smiled.
