This story is leaning heavily into fan fiction rules right now. Just because it's fun to write about doesn't mean it's at all accurate. There are good reasons teachers end up in prison when they have a relationship with a student. I had a newly graduated good looking teacher attracted to me Sr year of high school. He never acted on it at all. He did the right thing. I did however get him to write a fabulous teacher recommendation letter for me for my college applications.

Blueeyeddevil06 thank you so much for being my beta.

This idea came from coastwife465 on tumblr. He prompt was au with teacher Darien and senior student Serena

Teacher's Pet

Darien was trying to remember why he agreed to become the long term sub at the high school he had graduated from four and a half years ago. He was contacted by the principal, who was in a total panic, and he said yes. The 12th grade English teacher, Mrs Sayers, was only five months pregnant but was put on bed rest through the end of her pregnancy. They had not been planning on that. So now, he stood at the front of class waiting for the first bell of the day to ring. He wasn't looking forward to this. He remembered, too late, that he had hated high school.

Students filed in and sat at their desks. Many showed curiosity as to who the sub would be. As it drew close to time for the bell to ring to start the first hour, he walked up and wrote 'Mr. Shields' on the board. He put the chalk down and turned. Suddenly, it felt like all the air left his lungs. Smiling and laughing with her friend was the most beautiful woman he'd ever seen. He quickly went and sat behind his desk. He needed to get himself under control and quickly.

As the bell rang, he was thinking of all the most gruesome case files he was studying for med school. It was really working to quell his desire. That was until she looked up and locked eyes with him. They were crystal blue, and they almost had a magical quality to them. He quickly broke eye contact and worked through a case file where someone had gotten their hand stuck in a hydraulic press. He tried to picture it in graphic detail.

Weeks went by, and he discovered many things about her. She was ridiculously kind, sweet, happy, sexy, and horrible at English. His instincts were warring against each other. She needed help with English. and he should be offering to work with her, even a little. He also knew that he should be staying far, far away from her. No part of him actually wanted to work on English with her. French, now that was something he wanted to do with her.

It was a Friday after class, and there was a knock on his classroom door. He said come in, and he instantly regretted it. Serena walked in timidly and locked eyes with him. The familiar pull of desire for her flared in his gut. In a small voice, she said, "So, I'm horrible at English. I had a guy offer to tutor me, but… Well, it turned out that he was worse at it than me. Even I knew the sentence in English that he used to try to proposition me wasn't right." She shut the door behind her. He wished he could kill that guy and had the strength to ask her to open the door back up. His desire flared with the closed door. She continued, "Do you know anyone who could tutor me?"

"Serena, I'm sure I can find someone."

"Could you tutor me?" she asked in a hopeful tone.

He laughed bitterly, "No, that would be a terrible idea."

"Oh."

"Let's just say that it wouldn't be appropriate. It's nothing personal." Far from it. He added to himself.

She walked over and sat in one of the desks. She locked eyes with him and said, "I was hoping for something inappropriate from you."

He carded his fingers through his hair. "Serena, you don't know what you're saying." He was frustrated and damn did he want that. He sat behind his desk. He hoped the distance would help. She was his student after all.

She laughed, and her whole face showed humor. She slid her legs out from under the desk and made sure that he was looking before she slid them apart and locked eyes with him. "Somehow, I think I know exactly what I want."

"Serena, you need to leave. I'm your teacher."

"So, teach me. There's so much I want to learn from you." She gave him a sultry look. "I bet you know all sorts of things. I promise not to mind if you work me really hard."

Darien looked panicked. "You're going to get me in trouble."

Serena rolled her eyes. "You're being difficult." She slid her legs back together and got up out of the desk. She then stalked over and sat on his desk. Her legs dangled close to his body. She began unbuttoning a few buttons on her school shirt.

Darien knew he was in trouble. He was frozen and couldn't move. Well, he wanted to move his hand and run it all over her long sexy legs. Up to her… His eyes almost popped out when she unbuttoned a few buttons, and her plump breasts were exposed a bit. Her cleavage was so voluptuous, and he wanted to bury his head in it. He wondered what kind of noises she would make if he sucked on her nipple. He bet she'd be really vocal in her pleasure.

She shifted towards him, and he got an even better view of her breasts. He could see down her shirt. "You're terrible at pretending that you don't want me."

"I shouldn't."

She scooted over, sat in front of him on his desk, spread her legs, and put a long sexy leg on either side of his body. "You could. I won't force you to touch me. In fact, if you let me walk out that door, I won't ever come on to you again."

His brain shouted "No." He wanted her to stay. He said nothing and watched as she made a move to leave. He placed his hands on her bare legs. "Don't go." He was so fucking screwed.

Serena was relieved he wanted her to stay. She loved the feel of his strong, warm hands on her; she'd fantasized about it. She just needed to figure out how to get him to do more. She raised her hands to her blouse and undid the rest of the buttons. "If I stay, what do you want to do with me?" She gave him a sultry look.

He leaned forward and pressed his face into her cleavage. It felt so damn good. He then kissed and sucked his way down to her nipple. He took it between his teeth through the lace of her bra. He was hard as steel, and she was moaning. He didn't care about the danger from here on out. He would have her. She was sexy and wanted him. He was tired of resisting her. "Serena, take off your bra. I want to see your bare boobs and feast on them." He moved his hands higher up her legs. He watched her peel it off. It was so damn sexy.

She removed her shirt and bra. Then she carded her hand through his hair and pulled his mouth to her boob. She was moaning and arching her back. He rubbed his hand over her wet panties. Without removing his mouth from her boob, he stood and laid her on his desk. He switched to her other boob to nip and suck on it. He pulled his head back and said, "You look like a sex goddess laid out on my desk." He reached under her school skirt and slid his fingers through her folds. He then pulled off her panties. When he unbuckled his pants and pulled them down, his cock sprung out. "I'm so hard. I'm going to fuck you on this desk. You said you wanted me to teach you. This will be your first lesson, and don't expect me to go easy on you."

Her breathing was shallow, and her nipples were flushed, showing her arousal. "What's the lesson?"

He whispered, "The lesson is how only a man can satisfy you. I'm no mere boy chasing a skirt." He stroked his cock, "You will discover how amazing it can be. I will wreck you for anyone else."

He thrust into her and groaned. She was like a vice on his cock. He nearly lost it. She was perfect. "Fuck, you're so tight! Shit, you're gonna make me cum! Damn, Serena, you feel so fucking good." He held still for a bit. He was trying to not shoot off like a rocket. Curses kept tumbling through his head. She was wrecking him for anyone else already. He started thrusting into her and watched her laid out on his desk. He watched his cock slide in and out of her, wet with her juices. He heard their bodies come together and as he drove himself into her. He pounded into her and listened to her moan. Finally, both of them orgasmed together, and he was left wide eyed and panting. She looked absolutely debauched.

He pulled out, pulled her up, and held her against his body. "Get dressed and come to my apartment. I'll give you the address. We shouldn't leave together, but trust me," he lowered his voice and it dripped of sex, "we'll be coming together again."

She nodded and fixed her clothes. "Again, already?" She smirked at him.

"Serena, if you think I can ever get enough of sex like that, you're wrong. You're so tight and so hot." He whispered in her ear, "I'm addicted to you already. I won't ever get enough."

She made it to his apartment, and once she stepped through the door, she dropped her bag and started taking off her shirt, bra, skirt, and then panties. She stood before him completely naked.

"I'm going to spend time on your body. I bet I can make you scream yourself hoarse."

"What will be my second lesson? I feel I really got a firm grasp of your first one."

"Your second lesson is going to be about building up desire." He laid her out on his bed and took his time on her. He watched her writhe under his touch. She begged him to take her. She was wild for him. It made him feel incredible.

The next day at school, Darien tried to hold himself together. He was going to see her again, and even completely clothed, she was incredibly sexy. It didn't help that he knew what it looked like when she orgasmed.

He watched her walk in with her friend Amy, and her friend looked concerned. He overheard her ask, "What happened to your voice? Are you sick?" Serena shook her head, and he turned away from the class and smirked. He knew exactly what happened, multiple times.

Darien stayed sitting at his desk as he watched Serena hang back after class. She waited for the other students to leave. Once they did, she walked over and sat on his desk. "Damn, all I could think about in class was being laid out on this desk with you fucking me."

He gave her a shit eating grin, "I watched those boys check you out today, and I know they would never be able to satisfy you."

She shook her head, "That was the point of your first lesson, one I learned very well. I'll be at your apartment again tonight."

"I expected that."

"Cocky."

"You love my cock. And, I have so many things to teach you."

She gave him a sultry look. "And, today's lesson is?"

"Different sexual positions." He reached up, grabbed her boob, and pinched her nipple through her shirt, hard. He wanted her to be able to feel it during her next class. "You better go before we get caught." He released her, and she headed out.

That night, he had his cock inside of her as soon as she made it through the doorway. He was fucking her up against the wall, and she was moaning. He drove into her. "I can't resist you. It's torture in class." He drove himself into her. "I can't get enough." He pulled her with him before they found their release. He walked her to his room without pulling out of her. He then took her to his closet and pressed her against the wall. "Watch. Can you see us come together in that mirror?" She looked and nodded. "It's so sexy watching your body while I fuck you against my wall." They came hard.

Once they got their energy back, she asked, "What do I learn next?"

"Get on your hands and knees on the bed. Wait until you feel how deep I can bury myself into you from behind. You'll love it."

A week later, and he was hating the new game she had apparently come up with. She would sit in class and make him watch as she flirted with all of the boys around her. They would smile at her and pass her their numbers. She would shoot him a look out of the corner of her eye, and he would fume. He almost lost it when she placed her hand on one of the boys' leg. He saw red.

Everyone was leaving the class, and she didn't hang back to talk to him. His hands visibly shook. He was desperate for her. She didn't stop by his class or his apartment that day.

The next day, he had to hear about how she had hung out with a group of guys at the Arcade the previous day. He was ready to snap. "Serena, after school you need to stop by. We have to discuss your latest grades. They are unacceptable. You will need to take some extra lessons."

She locked eyes with him and smiled, "Yes, Mr. Shields."

She stepped into his classroom after school, and he slammed the door behind her, locking it. "Do you not want me anymore? Are we through?"

"Are you upset?"

"Of course I'm upset! You're with those boys."

"At least to them I'm not just a good fuck." She shot back.

He looked horrified, "What're you talking about? You're having sex with them too?"

She rolled her eyes, "No."

"Then what are you talking about?"

"All you want with me is to fuck me. I just get everything else I need from them; they are sweet to me."

"I…" He paused. He then narrowed his eyes, "If you actually wanted a relationship from me, you should've just said something." He pressed her against the wall. "You're an amazing fuck, but you're also the best woman I know. I was willing to take whatever you would let me have. Having sex with that hot body of yours is amazing. The things you can do, and the positions you can get yourself into are incredible. I would like it even more if I could have your heart too."

She locked eyes with him, "You already have it."

He smiled at her and nodded, "You have mine in return." He pressed her against the wall. "As for those boys."

"They're just what you say they are. I was bored with them immediately. I just liked watching you fume. You're sexy when you're angry."

He gently grabbed her wrist, pulled her over to one of the student desks, and sat her on it. He then reached up her skirt and pulled her panties to the side. "Mark, the guy who sits right here. He really wants you." He buried two fingers inside of her and played with her clit. "Tomorrow, when he flirts with you, I'll picture this. You, sitting here with my hand up your skirt fucking you with my fingers."

She moaned. "Let's get out of here. We can't get caught. I'll meet you at your place. What's today's lesson? You said I need extra ones."

"Role play."

Darien had her in his apartment, and he pulled her to his desk in the office. "This will work for our play today. We'll go with the naughty school girl fantasy."

She laughed, "Sounds perfect."

He paused and chuckled, "I've gotten to live so many of them out already." He sat in his desk chair and opened up his pants. "One is too far to really go. Even for me. This one is oral sex for good grades."

She smirked and played along. "Mr. Sheilds, you wanted me to talk to you after class?"

"You failed your last test. But, don't worry. I have a way you can get some extra credit." He ran his hand over her boobs.

She pretended to shift nervously. "What… what are you doing?"

"Touching you. I get to touch you whenever I want to now. Or, do you like the grade you got on your test?"

"I would do anything to fix my grade. What do you want from me?" She felt herself getting wetter. She continued to play along. "What do you expect from me?"

"To do anything I tell you to do. I want you on your knees, sucking me off. I fantasize of you on your knees in front of me. I can fix your grade if you make it a reality. Open those pretty pink lips for me. I want to see them wrapped around my cock."

She nodded. "You won't tell. This will stay between us?"

"Serena, I can promise everything we do will stay between us. I have a feeling that this class will soon be your highest grade. I have an endless amount of things I want to do to you. And, I can promise you an A if you let me do them all to you." He grasped her boobs again, "I want you so fucking much."

"Take me any way you want me then." She kneeled in front of him and took his cock in her mouth. She licked, sucked, and then deep throated him. He rutted into her mouth and cursed. He was losing his mind. She was incredible with her mouth, and he was trying to maintain some sort of composure. He wanted to fuck her down her throat so badly. She deep throated him again. He grunted and came hard. She swallowed it all up.

"You're so damn good at that!" He kissed her forehead. "I love you. That was fun."

"I love you too. Too bad it's going too far for you. I'd have a great grade in your class. Although, it might make someone suspicious of us." She winked, crawled out from under his desk, and sat on his lap. He stroked her boobs as he held her. "I really didn't want any of those guys."

"I should've told you how I feel about you."

She shrugged, "It all worked out, and you're sexy when you're demanding."

"It's good you think so because I'm an only child, and I don't like it when others want something that I think is mine."

"I already decided that I belong to you."

The next day in class, he watched Mark try to flirt with Serena, and he just smirked. He loved that girl.
