A/N: This is set the day after the events in "punishment." So that makes "mirror", "punishment", and this chapter in chronological order. I guess I did a mini-arc huh? The next chapter is 90% probably going to go out of order again. I don't want to write El losing her virginity just yet. I want to save that for later, I have a lot of ideas for them sexually exploring and the lead up to that. I may even do a time jump next time to after they've started having sex, but I'm not sure at this point.

I see a lot of you are into the whole jealousy thing, haha. I've got a few ideas for that, but I am trying to have a consistent plot/character arc for Mike and El, and the progression of their relationship, so any love rivals/issues in their relationship needs to make sense and work for their character arcs too. So we'll see for that, but I have a few ideas ;)

"Okay, so if y equals 1/2x plus 185, and x equals 10, what is the value of y…? El? El!"

"Huh?" El's eyes darted back to Mike's at the sound of her name, refocusing on the algebra practice exam. "Sorry," she said sheepishly, squirming around uncomfortably in her chair next to Mike. "What – what number are we on again?"

Mike caught her fidgeting and eyed her wriggling bottom with an amused look on his face. Their Wednesday tutoring session was nearly half over and they hadn't even gotten through most of the exam yet.

Most of the time, they were actually pretty good at keeping their sessions productive despite the fact that Mike had initiated a sexual relationship pretty much within the first week of becoming her tutor ("I'm your tutor, right? I'm supposed to teach you all sorts of things," he had said, as he stroked her clit and made her cum for the first time in her life during their fourth tutoring session), but today El really couldn't focus on the task at hand. She moved around in her chair some more, trying and failing to find a comfortable spot on the hard wooden seat.

Mike raised an eyebrow. "Uncomfortable?"

El glared at him, feeling her cheeks grow hot with embarrassment. The smirk on his face told her that he knew exactly what all her fidgeting was about. "No…I'm fine," she lied. She hated that smug look on his face.

The truth was, her ass was sore and aching, and sitting anywhere, especially on that hard wooden chair, really hurt. And Mike knew exactly why, because last night he had slapped her ass cheeks red and then mercilessly fucked her virgin asshole until they both came. And now here he was, taking in her discomfort with pride and gloating.

"I just – maybe we can switch chairs? Mine feels weird."

"They're the exact same type of chair, El," Mike retorted, that smug, amused look still on his face. She wanted to slap it off of him.

"Fine." El got up. "Maybe we should end the session then. I just can't focus – you can go - "

"El, hey," Mike grabbed her by the hips and pulled her to him, placing a soft kiss on her stomach and gently stroking his hands over her ass. "I know. It's my fault. I was a little…." He pushed his hands up underneath her skirt and lightly ran them over her swollen ass cheeks "...rough. Your ass must hurt today, huh?"

"It's fine." El felt confused. Why was he being so nice all of the sudden? It wasn't fair; she really wanted to stay pissed at him. "It'll probably heal in a couple days. I just can't really…sit today. It hurts."

Mike scooted back from the desk and then patted his lap, looking up at her expectantly. "We've got thirty minutes left to finish these problems. That's plenty of time. Just…sit on my lap."

When he noticed the incredibly skeptical look on her face, he said, "Hey, it's better than that hard wooden chair, and you don't have any other seating arrangements in your room."

El sighed. Fine, whatever. Mike was usually pretty good about keeping their sessions on track once they had started hooking up regularly outside of tutoring hours, and El really did need to ace this algebra midterm.

She plopped down on his lap unceremoniously, no big deal, the quickness with which she did it causing her pleated uniform skirt to fan out across his lap, so that her panties were directly over the fabric of Mike's pants.

Oh shit. He probably thought she had done that on purpose or something. For a second she wondered if she should sit up again to readjust and push her skirt back down behind her, but then – what if that was just drawing attention to it? What if he hadn't even noticed –

"Okay, so if y equals 1/2x plus 185, and x equals…" Mike started to drone on again, his attention going back to the practice exam and El tried to follow along this time too. Good. He hadn't noticed.

"So we have to plug in the value of x to this equation…" El started, trying to work on the problem. Maybe Mike was right. It did feel a lot better sitting on his lap than on a hard wooden chair, and now that the pain was a lot less she could really concentrate better –

Then she felt it. It was only for a brief moment, like Mike was just momentarily adjusting himself on his seat. His hips had pushed up against hers and then relaxed again.

"X, um, x equals 10 so we plug it in here…" El continued. She was being paranoid. Mike had just fidgeted in his seat, that's all. "So ½x would be ½ of 10, which is –"

She felt it again. The push of his hips against hers, his groin pressing itself to her core and then slowly retreating, only to push back up at her again. "Which is – five…" El tried to continue on, but it was definitely not her imagination anymore. In fact, he was now pushing up against her panties with such force that El was noticeably moving up and down on his lap, her breasts bouncing with his movements.

"M-Mike…" El closed her eyes, trying so hard not to lose focus. But it felt good, his hardness thrusting up against the thin cotton fabric of her panties, putting pressure on her sensitive clit every time it did so. "What are you – what are you doing – oh!"

He pushed up against her again, not even bothering to hide it anymore, thrusting particularly hard and sending a shock of pleasure through her as his ever hardening cock briefly pressed up against her clit through the fabric of his pants and her panties.

"Shh…just keep doing the problem…" He thrusted up against her again, "You're so –" another thrust " – close – " thrust "to solving it…"

But El had her eyes closed now too, it felt too good, and without realizing she was even doing it, El started grinding against him too, shifting her hips to rub her pussy back and forth along his hardness, trying to get the delicious pressure back on her clit.

El heard the brief clinking of his belt buckle and before she knew it his cock had freed itself from his pants and boxers and all that separated her pussy and his dick was the thin cotton material of her panties.

"Mike!" El tried to get off his lap but Mike's arm had wrapped around her waist, keeping her firmly in place. He shifted his hips briefly to the side to show her the dark spot on the crotch of his pants that the wetness from her aroused pussy had made and then went back to grinding his exposed cock on her panties.

"What? I can't let my pants get dirty from your pussy juices, El. It's not my fault how easily your pussy gets wet for me," he whispered in her ear.

With one arm still around her waist, keeping her from going anywhere, his other hand snaked down between where they were joined to position his cock exactly over the outline of her pussy lips through her panties. Then he started thrusting up at her, hard, so hard she was bouncing up and down with the force of it on his lap now, so hard that if it wasn't for her soaking wet panties his cock would be fucking her pussy and El wouldn't be a virgin anymore.

"Ah! Mike…" El keened every time he thrusted, it felt so good, her panties were thin enough that she could feel the outline of his cock as it pushed up against her, rubbing against her wet core.

Mike was nipping at the back of her neck, one of his hands had unbuttoned the second and third buttons of her shirt to reach inside, into the cup of her bra, squeezing one of her tits and playing with her nipples until they puckered and hardened.

She figured this was okay. As long as her panties stayed on, he wouldn't really be able to get inside her, and she could still kind of feel him, feel his cock as it pushed up into her wet pussy again and again and again –

Then she felt it, his knuckles brushing her pussy lips – her bare pussy lips – and she realized he was trying to push her panties to the side to put his cock inside of her –

"Mike, no!" El jumped up like she was on fire, Mike too preoccupied with getting his cock ready to push inside her pussy to keep her in his grip. He looked up at her, his hard cock still gripped in his hand, leaking pre-cum at the tip. She was panting heavily, still feeling crazy turned on, her tits spilling out of her pushed opened shirt. "I told you, I don't…I don't want to have sex."

"Sorry, I um, I got carried away." Mike was breathing hard, looking actually a bit remorseful. He patted his lap again. "C'mere. I won't – I'll leave your panties on."

El shook her head. It was too tempting. "No…it…it hurt my ass anyway. Sitting down like that." She hoped he would believe her lie. "Even sitting on you and not a chair."

"Okay then, no more sitting," Mike said, and before El could register what was happening, he was next to her in two strides, pressing her up against the wall of her room, his left hand gripping her thigh forcefully and pushing her right leg up so that her knee nearly touched her shoulder, leaving her legs and pussy spread wide open. He pushed his cock up against her panty-clad pussy, immediately resuming his brutal thrusting.

"Oh fuck! Mike! Oh!" She was helpless to resist him, his grip on her thigh bruising, the force of his thrusts ramming her hips against the wall repeatedly, and she didn't want to resist him anymore, it felt too good.

"Fuck El, you have on your thigh highs again," he grunted in her ear, "Your legs look so fucking good pressed up against your body like that, spread wide open for me."

"I told you I couldn't afford the tights," El yelped against his shoulder, trying to hang onto him for dear life, letting him take complete control of her body. He was pounding into her panties so hard now that her other leg was being lifted off the ground each time he thrusted, and she could feel the head of his cock, wrapped in the thin cotton fabric of her panties, push shallowly into her pussy, over and over again.

"Oh fuck, my cock is pushing your panties up inside your pussy, El. I'm ramming you so hard my cock is getting in there anyway, wrapped up in those thin pink cotton panties. If these panties ripped I would be fucking your virgin pussy."

Hearing him say it out loud, it was so naughty, she was basically being fucked but she wasn't, he was so hard for her his cock was finding its way into her pussy anyway, and the only thing that kept her from spoiling herself forever were these thin pink panties, now completely stretched out and soaked from her pussy juices and Mike's pre-cum.

"Mike, oh fuck, Mike!" El came hard, her pussy lips twitching and clenching down on the head of Mike's penis, the part of his cock that was pushing into her despite her panties. That must have caused Mike to cum too, because only seconds later he jerked against her and El's panties were suddenly flooded with a warm liquid, so much of it that it spread all the way to the back of her ass and dripped down her legs.

Mike finally let go of his painful grip on her thigh, letting her leg fall back to the ground. El's panties were completely soaked with Mike's cum, as if she had wet herself, but the panties had proven unusually durable, not having ripped or torn despite Mike ramming his cock into them over and over again. She was still a virgin.

Mike fell back onto the desk, breathing heavily, both of them trying to recover from their intense orgasms.

"Oh shit," Mike was tucking himself back inside his pants, "What time is it?"

El glanced at the clock on the wall behind Mike's head, "Oh, we ran over our session…"

"Shit. I had a meeting with Mr. Clarke about my final project right after our session. Fuck – I gotta go, El," Mike huffed, hurriedly pushing his books into his backpack.

"It's okay, Mike. You don't have to lie. You always leave straight away after…. Anyway. See ya next time."

Mike paused, and for a moment he looked like he was going to say something, but then seemed to think better of it. "Yeah," he said casually, "Later." Then he was out the door without looking back.

El looked at herself in her tiny full length mirror, all alone in her room. It was one of those cheap ones you found at Walmart or Target, and if you came at it from a certain angle, the reflection might look distorted or stretched out. But it was enough to get the job done for what she wanted anyway.

She still had on her thoroughly abused pink panties, now soaked in Mike's cum. El sat herself down directly in front of the mirror, and slowly watched herself peel off the cum-soaked, stretched out panties, revealing her bare pussy. It was soaked in Mike's cum as well, her pussy lips, inside and outside, glistened with a thin white sheen of his cum and El's own wetness. She dipped her fingers down to rub at her clit, looking in the mirror at how her bare pussy was covered in Mike's cum. It was such a naughty thought, she had to dip in two extra fingers into her pussy itself, watching herself finger her cum-soaked pussy, Mike's cum, imagining her fingers were Mike's cock sliding in and out of her cunt, thinking about how she had come so close to the real thing mere moments ago, the feel of the outline of the head of his cock repeatedly pushing its way inside her virgin pussy, over and over again. Fuck she wanted Mike's cock, she wanted him to fuck her pussy so bad, she pumped her fingers in her pussy harder, wishing the panties had ripped, wishing he had just ignored her and torn them off and fucked her pussy raw so she could feel his hard cock stretch out her virgin cunt for the first time and – oh shit she was cumming again, all over her hand, her new wetness seeping out of her and mixing in with Mike's cum that still glistened on her mound and clit and the inner walls of her pussy.

She wanted him.

She wanted his cock so bad.

She didn't know how much longer she was going to be a virgin anymore.
