Darcy Lewis didn't enjoy the guest speaking parts of her job one bit.

It was worked into the contract of her last research deal. She thought that astrophysicists would dou, y' know, astrophysics stuff. Science, and experiments! She didn't really imagine herself giving lectures to college kids.

It was boring. And annoying. And to top it all off, the horny little menaces never learned anything, because they were too busy staring at her rack to actually take notes or, you know, LISTEN.

Look, Darcy understood it. Her rack was pretty amazing. She loved it to! But that didn't mean she wanted to stand around watching her lecture go in one ear and out the other as a bunch of teenagers just getting used to sex imagined her wearing less clothes.

When she climbed into her car this morning, Darcy expected the worst. This wasn't even a prestigious university that she had been booked for, just a small state school near Queens. She was sure it was going to just be more of the same.

At first, her prediction seemed correct. She set down her coffee, hit the class with a charming joke that got a few chuckles and a lot of stairs, and dove straight into things.

She was on autopilot, assuming that no one would be listening. But suddenly, a hand went up.

"Yes?" Darcy said, calling on them out of pure shock. That had never happened before. And it was a boy, no less!

"Well…" he said, hesitating as he spoke and looking down at his notes. "It's just that, wouldn't the gravitational pull change the equation in this case? I'm not sure… I don't think this is right…"

Darcy jumped, realizing she'd been staring at him. He spoke haltingly and nervously, but what caught her attention was that he was looking down at the desk. Not only had he taken notes, he was looking at them now, not her body. Ass she listened to what he was saying, she realized that he was right! She made a mistake that she hadn't caught as she spoke without thinking.

"What's your name?" she asked.

"Me?" the boy looked up. "Peter Parker… Ma'am!"

He was cute. Physically cute, and with a shy personality that made something inside of Darcy activate. She smiled, walking up to his desk and leaning forward.

"Well, Peter Parker. Thank you very much," she said. "You're absolutely correct."

The position she chose gave him a look down the window at the top of her blouse, down at acres of glorious cleavage. Peter blushed bright red. Darcy chuckled as she stood up.

She liked this one, she decided. She liked him A LOT. Enough that she wanted to have some fun with him.

Darcy returned to the whiteboard, feeling people's eyes move temporarily away from her rack down to her backside. That was kind of her fault, because she'd worn a rather tight skirt to go with her blouse. She was glad she had now, though.

She continued giving her lecture, now without any stupid mistakes. She was fully awake and paying attention now. Every time she looked back, Peter was dutifully taking notes, only looking up periodically.

Smirking, Darcy went up on her toes to write along the top of the whiteboard. When she did, she leaned just enough for her skirt to ride up. A glimpse was offered of what was beneath: her favorite pair of purple panties.

She turned back right after as if nothing happened. Peter was staring down at his notes… but his cheeks were bright red and he was writing faster than usual.

Damn. Darcy blinked. That kid could write! She didn't no it was possible for a person's hand to move that fast.

Still, she had gotten what she wanted. Once could have been a coincidence, but twice was too much.

This kid had her absolute FAVORITE kind of reaction to teasing.

For the rest of the period, Darcy amused herself by continuing to mess around. She happened to drop her marker right in front of Peter. When she bent over to pick it up, her blouse was strained so far that the lace of her bra was visible. As she walked between the desks, seeing if anyone else had questions, she tripped over the leg of a chair.

The plan was to fall so that her breasts mashed against Peter's back. That would be the nail in the coffin. Darcy wouldn't have been surprised if he shouted in surprise, which she would've loved. But somehow, Peter reacted instantly.

He spun around and caught her shoulders. Darcy blinked. He wasn't a scrawny kid, but he as pretty small, yet his grip was incredibly strong. It was… nice. She wouldn't mind staying like this…

"Sorry!" Peter said. "Here!"

He helped her back on her feet, then let go of Darcy's arms. Even though she hadn't managed to shove her breasts against him, they had still ended up in his face, causing a lovely scarlet blush. Satisfied enough with that, Darcy walked back to the front of the room after telling him no apology was necessary.

She already missed feeling that touch. She made her mind up about what she had to do.

When the bell rang and students gathered their things, Darcy said, "Peter, you can stay behind."

"Me?" Peter said.

"Yes, you," Darcy said. "I'd like to speak with you."

A couple of the other kids snickered. A few of the boys looked like they wished they could take his place.

They didn't know the half of it.

When the last of the other students had filed out of the room, Peter approached her tentatively, leaving his backpack slung over his seat.

"I'm sorry about earlier," Peter apologized again. "I just didn't want you to fall, and then I just kind of moved, and I…"

"I told you already that you had nothing to apologize for," Darcy said. She barely looked up at him, instead staring down. Her fingers unbuttoned the first button on her blouse. "I didn't keep you here because I was angry."

"They why…"

Darcy had already undone the second button down, and now popped open the third. Peter trailed off and hastily averted his eyes. Darcy licked her lips. What a delectable reaction.

"Are you dating anyone, Peter?" she asked.

"Not anymore," he said, his voice sounding sad.

"A breakup? Those suck," said Darcy. "I remember my first college breakup. You just want somebody to console you, you know?"

The fourth button was undone, leaving on the fifth and final one to go. Her blouse was already hanging open down the middle. Her G-cup lacy bra was visible, as well as her smooth stomach underneath that.

"What are you doing?" Peter asked as it became clear she wasn't stopping.

"What do you think?" Darcy said. She pulled off her glasses, tilting them to the side and sucking on the end of one of the arms. "Consoling you."

Peter's head turned back, and as soon as it did, his eyes went wide. Darcy's shirt was hanging completely open, only the sleeves still on, but that wasn't all. She had kicked one leg up on the desk they'd given her, leaving the other on the floor, giving him a view directly up the bottom of her skirt.

"You can say no, Peter," Darcy said. "Buuut I might have to consider you clinically insane if you do."

When Peter didn't shoot her down or turn away, she grinned.

"Get those clothes off!" Darcy urged.

Peter yanked his shirt off quickly. He got his jeans off even faster. Despite everything, Darcy couldn't help but blink.

"That was fast," she said.

"I have a lot of practice taking off my clothes," Peter explained casually.

She almost thought it was a sex brag, but he didn't seem nearly experienced enough for that to be the case, because as soon as he was in his boxers he froze, just looking. Darcy decided to make it obvious for him.

She loosened her skirt by undoing the zipper, and kicked it off so that it landed over Peter's head. When he pulled it out of the way, she had slid her panties to the side, revealing the pussy underneath.

"Come and get a taste," Darcy said.

Peter dropped onto his knees in front of her. Darcy watched him, tensing her lower body in preparation. She felt his hands offer the same surprisingly strong grip that had held onto her shoulders as he pried apart her thighs. Soon all she could see was Peter's brown hair sticking up between her thick thighs.

Darcy was benevolent. She would give him some pointers, and get this college kid a bit more experienced and ready for his next girlfriend. Not to brag, but she'd had her fair share of relationships, so she would no.

Darcy's back stiffened. Her lips closed around the tip of her glasses that she'd been sucking on, biting down for dear life. Pleasure rocked her whole body as something warm and strong stuck itself inside of her, instantly finding her clit.

"Uhhhn!" Darcy moaned girlishly.

The feeling disappeared. Peter's face appeared above her legs, looking concerned. "Did it feel alright?" he asked. "I didn't do it wrong, right?"

"No!" Darcy said. "I mean… Please keep going?"

She'd planned to keep toying with him a little bit, but the thought of missing out on that feeling by making him talk was just too much to bear.

Peter's tongue slid inside of her again. Darcy's whole body felt amazing, so much so that she watched her toes curl on the desk. She managed to keep down any more unbecoming moans, but was unable to stop gasping loudly. She tried to shift her hips only to find that she couldn't. Peter had grabbed onto her, and his grip was so strong that she felt like she'd been locked in place.

Darcy's head tilted back, looking up at the ceiling. She felt her clit being stimulated more and more, the pleasure sending shockwaves throughout the rest of her body. One of her hands grabbed Peter's brown hair, which didn't even slow him down. Her other hand pushed under her bra from below. She pinched her own nipples, squeezing and rolling the pink flesh. Her body felt hot all over, and this helped alleviate one part of that.

Peter's tongue delivered one final swish. Darcy knew there was no keeping her voice down this time.

"Ooooooohhhh!" she moaned, making a funny face that she was glad Peter was too deep between her legs to see.

She orgasmed all over his face. She could see it making his mouth and cheeks shine when he pulled his face out.

Peter looked up at her with pleading, brown eyes.

"I'm a little excited, Professor Lewis," he said innocently, standing up. "Can I put it in?"

There was no need to ask what he wanted to insert into her. Darcy's eyes went down, trailing over his ripped abs to look at his underwear, which were straining to hold in an enormous phallic shape. She nodded because she didn't trust her voice.

"Gee, thanks!" Peter said, before scooping her up.

He carried her like she weighted nothing, laying her down on the mostly empty desk next to them. Darcy still had on her unbuttoned blouse and bra… until Peter tore the latter in half as easily as if it were paper. Darcy's incredible rack bounced as they were revealed, and Peter bent forward to bite them.

Darcy felt his tongue licking all over her flesh. How was this kid so good at this? It was like every time he was about to do anything wrong, something in his head warned him against it. What was left was a succession of nonstop attacks on Darcy's most sensitive zones.

As he sucked on her tits, he frantically pushed down his underwear, trying to hop out of them. He managed it, but it was tough, considering what he had underneath.

When his dick cam free, Darcy briefly got a look at nine thick throbbing inches, and then they had been thrust inside of her.

"Uhhhn!" she moaned. "Uhn!" Unh!"

She couldn't help but sound out her pleasure. Peter crawled onto the desk with her, rolling her over on her knees and fucking her from behind. Darcy's chin rested on the wood as she felt his dick slam inside of her over and over, incredibly fast.

"You feel great, Professor Lewis," Peter grunted. "Better than great. You're amazing!"

Darcy could feel her ass turning red from the force he was pounding her with. She had meant to tell him to stop calling her Professor Lewis… But there was something hot about it now. She WAS his professor, bent over on the desk she'd been loaned by the university, orgasming on his tongue and monster cock.

How had she been planning to tease this kid again? If it went on like this, they were going to need a wheelchair to get her out of here.

Peter grabbed her elbows, dragging her body up. Darcy still had her blouse on by the sleeves, although it was flapping everywhere without the buttons done. When Peter pulled her up, he somehow managed to hit spots even deeper inside of her. And was it her imagination, or was he speeding up?

The boy was already going as fast as the best boyfriend Darcy had ever had in bed. She knew he was in shape, having seen Peter's abs, but this was still impressive. But he wasn't stopping. He kept on getting faster, and faster. It reminded Darcy of the times she heard Thor and her friend Jane going at it, when Thor would give Jane exactly as much as an ordinary woman could handle without physically breaking.

Which didn't mean that they didn't break physically.

Darcy's boobs were bouncing all around her chest, shaking and quivering like huge bundles of fat that they were. Her tongue dropped out of her mouth, hanging and flapping around as Peter fucked her. The more times that huge dick was inserted into her, the less conscious thought Darcy became capable of.

She moaned loudly and frequently, while Peter just grunted. He wasn't even breathing hard. Darcy arched her back as much as it would go, her body merely reacting to the intense breeding she was being put through.

All those boring guest lectures had been worth it, if they eventually led her to a dick like this.

"Miss Lewis…" Peter groaned, which she supposed was a bit more personal than using the professor title.

But what Darcy really cared about was what this represented. She recognized his tone of voice. She'd heard it from men before. Peter was cumming… but he wasn't stopping.

He fit ten more thrusts into the next few seconds, causing Darcy's eyelids to flutter and making her wonder if her sanity would survive this. Then, he exploded all over her insides.

Darcy felt his cum saturating her pussy. It was warm, and there was so much of it. It felt sort of like eating a large, warm meal, and feeling it inside of your stomach. She smiled stupidly, her tongue still out, as Peter let go of her arms. She dropped back onto the desk, but thankfully had those huge breasts to cushion her fall.

"Crap! I'm sorry, Miss Lewis! I didn't mean to…"

Peter tried to wipe away the excess cum that was already beginning to spill out of her hole, but Darcy's voice stopped him.

"That's alright, Peter," Darcy said, her voice sounding stilted as if she was drunk. "We'll call it extra credit."

"...Are you sure I can't make up for it somehow?" Peter asked.

Darcy looked back at him, craning her neck.

"Your number would be a good start," she said tiredly. "And maybe a nice dinner somewhere…"
