It was a busy day at Springfield High. Not the least of which because there were several big mid-term tests coming up. Though Lisa Simpson probably had it the worst. She was taking several AP courses at once. Her nose was deep in the books.

Luckily she had Milhouse tutoring her. He was her study buddy, and had agreed to help her out with all the stressful workload. But he had so many ulterior motives right now. Namely, he wanted to try and get with her again. Not that he would say that to her face.

Still it was kind of hard for him right now. He was dressed trying to look cool, in a leather jacket and smooth jeans. He’d been doing that a lot lately. He wanted to impress Lisa. But she wasn’t paying attention to any of it. She was busy studying like a good girl.

She didn’t look anything like the studious bookworm that she was though. The years had been good to her, and she wore her traditionally spiky hair back across her head in a very feminine hairstyle. She also wasn’t afraid of showing off skin either, wearing a short skirt that showed so much of her shapely legs and a small little button up t-shirt that rode up her midriff. Anyone who didn’t know her would think she was your stereotypically stuck up hot chick.

The both of them dressed like that, some people would have thought they were a bit of an awkward couple. They definitely didn’t look like they belonged in the school library. They were also well a ways away from the main area in the library, in a corner behind several shelves. It was so sheltered that they could barely hear the noise from the main area.

As the two were going over the material, Nelson Muntz noticed the two of them. He liked the look of Lisa, and he had to keep himself from snickering at the look of Milhouse. The blue haired dork was trying to put on the look of a bad boy, but Nelson was the genuine article, wearing jeans, a vest, and a t-shirt that clung to his body with rolled up sleeves. He was plenty buff by now too, with one of his arms covered in a tattoo sleeve of roses and skulls. Definitely the look for him.

He wasn’t usually one to be found here in the library either, save for looking at porn on the school computers. But right now he was looking for trouble. And these two were the perfect target.

He walked directly over to them and pushed all her books right onto the floor. “Ha-ha!” He made to leave.

But Milhouse wasn’t having it. He stood up. “Hey! What’s the big idea!”

Nelson wasn’t intimidated at all. Not wasting anytime, he looked right at Milhouse. All his vain attempts of trying to look like the tough guy went up in smoke in that instant and he cowered a little bit. Nelson sensed it too and pushed him right down onto the floor and reaching for the back of his pants, pulled his underwear right up, giving him a killer wedgie. “Ha-ha!” Then he looked right at Lisa with a smug grin on his face. “Ha-ha!”

Lisa stood up this time, looking right at him. Unlike Milhouse, her eyes were blazing. “You got a problem you smarmy little punk?”

“If I do, what are you gonna do about it?” Nelson said.

She slapped him right across the face as hard as she could. The impact of it was so strong that it was heard throughout the library. He was stunned a bit too, he almost backed up a bit. He moved his hand right up to her cheek. But he didn’t whine about it or take in a breath. Instead he just chuckled to himself.

Then he whistled loudly. “Damn. Wasn’t expecting that one.”

“That makes sense. You are just an idiot! You probably don’t even know how to do long division.”

He looked her over. She had grown up nicely and he imagined just how good she must have looked naked. “I wouldn’t mind dividing your legs apart right now and fucking you up real good.”

Lisa had gotten male attention when she was younger and even more now at her current age. But it was rare for a guy to take that much initiative with her. She blushed a bit, remembering the time they were briefly an item. But she pushed that to the side. Right now she was trying to think of another comeback to try and throw him off guard.

Her getting hot and bothered by his remark didn’t go unnoticed by Nelson. He could tell how much that comment got to her. Despite the look she was giving him, he could tell she wasn’t nearly as offended as she was trying to convey. Now was the moment to strike.

Without warning, he grabbed her shoulders and pulled her forward into a kiss. He didn’t waste any time with trying to be gentle with her, he was pushing his tongue right into her mouth. What surprised him was how easy it was. He expected her to be a little more resistant this time, try to break free or hit him right where it hurt. Instead she had opened her mouth up from the beginning.

There were so many thoughts going on in Lisa’s head right then. She remembered the last time they kissed almost a decade ago, he had done it then purely to shut her up. No doubt it was the same here. That didn’t keep her from feeling nostalgic from feeling his lips right up on hers, butterflies going on in her chest. She didn’t realize she had let his tongue into her mouth until it was too late.

And there were other things going on with her than just in her mind. His sudden forcefulness with her was getting her a lot more turned on than she had realized. Her nipples were getting hard and no small amount of wetness was forming in her pussy. Even with him still stirring his tongue inside her mouth, she simply relaxed herself.

When he pulled back from her, there was a trail of spit between their tongues. Milhouse was looking up in horror at the scene above. He could see that dreamy look in Lisa’s eyes. And then when Nelson put his hand up her skirt and shamelessly felt up her crotch, Lisa bit her lip and put her hands down on the table under her, leaning back a bit. He was already a little sore but he was starting to get heartbroken too.

He pushed her down onto the table, landing on her back. He hiked up her skirt and pulled her panties out from the skirt, down her legs, and right on top of Milhouse’s head. He had to fight off the urge to gloat with another “Ha-ha!” at that last one. Normally he would have done it no problem. But there were other concerns for him at the moment.

“You want me to stop?” he said, looking her right in the eyes. Her being naked down there and at his mercy, she realized she wanted it a lot more than she was comfortable with. She didn’t want him to do anything to her. But she was enjoying it too. Her mind was going back and forth on what she should say next. “But I tell you what, you want me to stop and I won’t eat out your pussy.”

Lisa wasn’t going to answer that one. She huffed and just turned her head to the side to try and look disgusted. But she didn’t say no.

Nelson was curious on how to play this one out too. He lowered his head inside her skirt and between her legs. She felt it too, his breath right on her naked vagina, and deep down waited for him to do it. Not hearing any refusal from her, he made his move.

He gave her a strong lick right in between her vaginal lips. Lisa was already hot wet from everything that had gone down, and he tasted her lusts right on his tongue. The instant he did that, she quivered a bit. He felt he tremble a bit and stopped, moving his head out not from any sense of chivalric honor, but just to see the look on her face. She was looking to the side but her face was redder than ever and she was sighing sweetly.

“You like that?” She didn’t answer. Shrugging his shoulders, he stood up and made to go, stepping over the hurting Milhouse.

That’s when Lisa said “Um...” in a very clear voice. Not a moan or a whimper but a very clear voiced objection to him leaving. Grinning, he looked right back at her. Milhouse was about to get up again, but Nelson just shoved him down again and moved right back to her. They locked eyes again and she slowly nodded.

Taking that as the signal he needed he hiked up her skirt this time, revealing all of her lovely legs and a bit of her shapely hips too. It was for his pleasure as well as it was for Milhouse to get a good look at him eating out Lisa’s pussy. He moved his head down again and resumed feasting on her snatch.

This time Nelson was far more blunt with his cunnilingus. His face was right up against her crotch and he was moving his tongue as deep inside of her pussy as he could go. She was getting wetter and tighter than he had expected, and the scent of her juices were deep in his nose. He grunted like a beast, giving it to her hard.

Lisa was moving her hips right up against his face. Nelson was so aggressive with her and it felt so good. She started moving her hips right up against his face, shamelessly embracing her lewd desires. He already knew how much she was enjoying it from directly eating her out, but her loud moans told the whole story to Milhouse too. If they weren’t in a small corner of the library away from the main area, everyone would have heard it and the whole school would be abuzz of what a slut Lisa Simpson was.

Milhouse was watching in horror. That didn’t keep him from pitching a redwood right in his pants. He got up, ready to actually fight Nelson. But when he saw Lisa clutching her chest to feed her own arousal and grabbing the back of Nelson’s head, shoving his face right into her cunt, he got angry at her too. Fed up, he stormed off, intending to tell the librarian about what was going on.

Lisa watched Milhouse walk away. Far from discouraged, she wrapped her legs around Nelson’s shoulders. Only a few seconds later, she climaxed, letting out a low grunt nobody would ever associated with someone as prim and proper as she was.

At that point he was moving his tongue all the way inside of her. Her juices flooded all over his face, and as he was continuing to torment her pussy with his tongue, her aroused smell filled his nostrils. He looked at her aroused clitoris. The nub was twitching underneath the hood.
