Darien came home from class, and Serena was studying. She did that more than ever before now that she was majoring in political science. She felt she should be good at it with her royal first life, and it gave her the confidence she'd been lacking in school before. After all, she was trained to run a solar system, which had to be in her brain. The girls remembered their attack powers on instinct, and she figured she should remember her training that way too.

Mainly it meant she actually tried. He thought she was doing better because she was actually cracking a book. That and he helped her study any time she had a question. He loved encouraging her in her studies and seeing her hard work pay off.

He loved coming home to her studying on the couch. It was the only place she would study, actually. She loved to scatter her things across the coffee table and lounge on the sofa. It all looked like a beautiful, chaotic mess to him. She was in his life, and he loved how much room she took up. Gone was the sterile feeling to the apartment that he had cultivated before. Now every room felt lived in. The place felt alive, and he loved it.

He was smiling at her as she studied and then noticed her skirt. It was pink, of course. He had really come to love that color. It was so her that he thought of her every time he saw pink. This time, what really drew his attention was that her skirt wasn't covering all it was supposed to right now, and she had no clue. Her panties, also pink, were peaking out as she lounged on the couch. They were the pink lace ones he bought her a few weeks ago. He couldn't help but buy her things like that now. He loved picking out things for her to wear.

He swallowed hard, and she looked up at him. "Is everything okay?" she asked.

He dropped his bag and kicked off his shoes before stalking over to her. He then leaned over and traced the edge of her exposed panties. "Ready for a study break?"

She looked up at him seductively and spread her thighs apart, exposing her panties to him. "I'm up for sex if that's what you're asking. Suddenly I'm wet, and I think you need to do something about that."

He hooked his finger through the crotch of her panties and caressed her pussy with the back of his pointer finger. "Care for some role play? I'm in the mood to take from you right now, but I don't have anything specific in mind."

"Hmmm…." she said, thinking. While she did, he fingered her clit slowly. "What if you're a naughty professor. My grades are fine. You just desire me and tell me you watch me in class."

He thought about how he could act out her idea. "So you come in to meet about a paper, and I come on to you?"

"The paper topic you assign me could be about something sexy, and you can offer some dirty suggestions. It doesn't have to be realistic at all, just sexy fun."

He smiled, "It could be about the female orgasm, and I could offer you more practical help."

"Damn, that's hot! Okay, you go to your study, and I'll prepare some questions I have for you. I'll also do an outfit change."

He looked down at her exposed panties with her legs spread and his finger between her folds. "You look incredibly sexy now," he growled.

She smiled, "Trust me on this one."

"Always."

…..

Serena knocked on his study door and heard him call for her to come in. She smiled and opened the door. She heard him suck in a breath.

Darien choked on his tongue, "Hot damn!"

She giggled and swayed her hips. She figured if her paper was on a sexy topic she would dress the part. She was wearing a black body-con dress that showed most of her plump breasts and all of her long sexy legs. There was a cut out at the center showing off her flat stomach and her back.

Darien got in character and raked his eyes over her body, "I knew I picked the right topic for you."

She sat in the chair by his desk and pulled out a notebook. "Thank you, I had a few questions on the material you wanted me to cover. I appreciate you meeting with me to go over them."

"I'm always happy to assist my students who are willing to… put in the work."

"I'm curious why you picked this particular function of the body for me to write for your class on anatomy. It will give me perspective on what you're looking for from me with this."

"I have realized that my class has been difficult this year and while you have decent grades I'm trying to be kind. Actually, I picked topics for all my students that would give them an advantage on this writing assignment."

She looked at him from under her eyelashes. "What about the female orgasm made you think I'd be good at it. I'm straight. You do know that, right?"

He smiled and leaned back in his chair, "Oh, I know that, Serena. You look like a girl who knows how to satisfy herself. Someone who can take charge of their own orgasm. It would be a good perspective for you to work from."

"Are you sure that's appropriate for you to say, Professor Shields?"

He snorted, "Only if I'm right. Am I?"

"Yes, you are," she said, locking eyes with him.

He flicked his eyes to her breasts and back to her face. "Tell me, are you able to finger yourself to orgasm or do you use toys?"

"What?"

"I'm helping you with topics for your paper. Write this down," he pointed at her notebook. "Also, write down the questions of do you fantasize while you touch yourself, and what's your favorite one."

She wrote them all down in her notebook. "This paper will be… x rated."

"It should be. It's an x rated topic after all."

She leaned a bit forward, "And this topic is appropriate for me to write about because…?"

"I'm tired of reading boring papers. That's what all but yours will be. I'm saving it for last. It's my reward for getting through the others."

"What are some of the others writing on?"

"Boring topics like the function of the heart, the circulatory system, the digestive system, drivel like that."

He looked at her breasts and licked his lips, he didn't remove his gaze when he said, "I'm very interested in reading your paper about your orgasms."

He then smiled and said, "I also want you to write about what you want out of a man to achieve the best orgasm, where is your g-spot."

"Why? How is that relevant?"

He raked his fingers through his hair, "Because it's all I can fucking think about when your in my damn class in the front row wearing those short skirts and thigh high stocking."

He stood abruptly, and looked at her with intense desperation, "I'll give you an A on the assignment if you let me turn it into a group project. You won't have to write a damn thing if you'll let me take you home and deconstruct how to bring you screaming into an orgasm. It will mean I have to get hands on with you and your sexy body. We'll turn your topic from masturbation to being fucked by your professor."

She spread her legs for him, and said, "I could go with not having to write a paper. Do you think you could get me off?"

He kneeled down in front of her, reached up her dress, moved her panties aside, and sank a finger into her pussy. "With how tight you are I can have you wild with desire. I'm an anatomy professor after all and I know the female body well."

"And I hadn't heard any rumors that you were the type to fuck your students."

"I'm not. You're the only one I've ever touched. Will you let me take you home and work out the details of this group project?"

"Yes."

He took her to their room and smiled at her. "And now, Serena. Time to state the topic of this paper in the opening paragraph. Let me. The subject of this is to show how to bring one, Serena Tsukino, to orgasm multiple times."

She smiled up at him and worked her red lace panties down her legs and dropped them on the floor. "You can keep those professors."

He picked them up and inhaled her scent. "Intoxicating." He then put them in his pocket.

"Now, tell me how you get off. I want to know what kind of things you like."

"I actually don't masturbate much. I don't need to, I have no problem getting laid. But when I do, I use a vibrator. It enables me to get lost in my fantasy world. I like to be overwhelmed with desire."

"That I can do. Can you do me a favor, call it a special treat."

"What?" She asked in confusion.

"When you wear those short skirts every time don't wear panties and spread your legs for me so I can see your pussy while I'm teaching in class. There is a reason I have you sitting in the front row."

"You are so horny when it comes to me."

"Yes, I am." He raked his eyes over her body, "You're the sexiest woman I've ever seen. And I really want you to call me Professor while I fuck that tight cunt of yours."

"And what do you think you can teach me about sex?"

He opened his pants and pulled out his hard cock, "What do you think?"

"Wow, you're huge. Now I'm excited to work on this group project. Where should we start?"

"Mutual pleasuring, first we sixty-nine." He pulled her to him, "Think you can handle my big cock in your mouth?"

She peeled off her dress and dropped it on the floor and was bare to him. She didn't bother with a bra. "Think you can handle me? I'm a bit wild, and I like it rough."

He grabbed her hair and yanked her to him, "Good. I knew you'd be a fun fuck. Your body screams of great sex."

He then pushed her down onto his bead and started stripping as he feasted his eyes on her body. "Let's change the topic of your paper from the female orgasm to wild sex."

He crawled over her once he was naked and bit one breast. "Your boobs are so plump. You're like a living wet dream."

"I think we need some pramitores for wild sexy, Professor."

He chuckled with his teeth full of her boob. He then released her and thrust two fingers in her mouth, "Suck them like it's my cock." She did and he moaned. "It's for an A, Serena. Pramitores get you a B. That decision is up to you."

He removed his fingers, and she made a sucking sound when he pulled out. She said, "Then anything, and I mean anything, goes. I want an A plus on this assignment though. Trust me, my work will be top notch."

"A plus it is then. I'm looking forward to playing with your body in any way I want tonight. I've had so many twisted fantasies of you." He then lightly grabbed her neck. He didn't squeeze at all, but he applied light pressure. "You'll give me anything I want. Hear me?"

She nodded with lust flaring in her eyes. "Choke me a bit harder. This is so fucking hot!"

He applied only a slight bit more of pressure and smiled down at her. "You're going to be at my mercy all night long. I'm in charge here. Do you have any idea how sexy you are?! I want to fuck you so hard you're still walking funny tomorrow. I want to see you walking into class still affected by my big cock!"

He released her neck. "Sit on my face and suck my cock. I want to taste you."

He laid on his back and she did the splits, bringing her pussy to his waiting mouth. He groaned, "that's so hot!" She then moved and slid his hard cock in her mouth and began sucking and licking on him.

His hands went to her nipples, pinching them, while he fucked her pussy with his tongue. He tasted her getting wetter and wetter and it drove him wild.

Serena was working his cock and licking. She took him deep down her throat and he moaned into her pussy. She loved it when he did that. It drove her crazy. She made sure to keep him moaning and it brought her quickly to orgasm. She then sucked him into joining her orgasm and took all his seed down her throat.

She flopped on her back and she moaned, "You're right. You're the Professor, you're so good at that."

He moved to climb over her. "And you're right. This is definitely A plus material. Now I'm trying to decide how to fuck you. I have a plethora of ideas."

He laid on his back again, "Ride me and beg me to fuck you again. You know this one night would never be enough."

She moved over and sheathed him. She then locked eyes with him as she began riding him, "You're the expert on the female orgasm. I was hoping for some extra help from you in this area of your expertise. I'll study hard and be your willing student. I want to learn all about orgasms and my body."

He was snapping his hips up into her and it felt so damn good. "Grab your boobs and drive me crazy!"

"Yes, Professor!" She did, and he pushed her off of him, and flipped her to her stomach. He then spanked her on each butt cheeks. "You're fucking your professor for a good grade. You're so naughty! Look at you traiding sex for something like some whore!"

He then lifted her hips and slammed his cock into her from behind. "You should be punished. Take my cock like a good girl."

He then lost himself in the sex and her clenching her inner muscles. He took her hard and orgasmed at the same time she did. He then collapsed onto her, Panting out his breath.

She smiled and looked at him over her shoulder, "Told you it was worth an A plus."
