A/N: This is set after "breakfast" - after El has lost her virginity and after she has been on Christmas vacation with the Wheelers. Mike and El are now back at school after Christmas break.

I wasn't kidding when I said Mike is super rich in this AU. He's not just upper middle class like he is on the show, he's properly rich. It just makes the power difference between them even greater, which is hotter. Hope you guys enjoy!

Ever since El had finally lost her virginity to Mike, they had been fucking like rabbits; it was almost non-stop, everyday, every time they found they were alone with each other they would end up having sex. It was like she was crazed, like after all that time of holding off and doing everything but let him fuck her pussy, once the deed was done, it was like El couldn't get enough of taking in Mike's cock between her soft, creamy thighs, into her constantly aching and wet slit, like it was the one thing El's tight and pink pussy was designed to do – be fucked by Mike Wheeler's hard cock.

They had fucked every chance they could get while El was staying at the Wheeler house (or, more accurately, mansion) over Christmas break. Mike and El still regularly snuck into the other's room at night, just like they did at school, sometimes Mike would take her for a drive around his hometown of Hawkins and afterwards they would fuck messily in his car, or in the Wheeler's outdoor jacuzzi, while snow gently fell around them, leaving gooseprickles on her shoulders and the tops of her breasts while her pussy was getting fucked in the hot water, or in any one of the giant bathrooms in the Wheeler house, where Mike loved surprising her in front of the full length mirrors, loved to make her face her own reflection and watch her own newly deflowered pussy take in his cock in again and again and again.

Now that they were back at school and the new semester had started, they hadn't had as much time to see each other as they did over break, though they still had sex every day, usually Mike sneaking into her room at night or sneaking El over to his, and sometimes they could sneak off at other times, like when they had fucked in the study room of the library, or when Mike had somehow found El on a bathroom break during fourth period and ate her out in the girl's bathroom.

They had been having a lot of sex. And El was worried.

When El had first come to the Catholic school, they had separated all the boys and girls and took them to two different auditoriums. Sister Helen had shown videos and pictures to all of the girls about Sex and Pregnancy and Abortion and it had scared El at the time and it still scared her now. Sex was a Sin, it was naughty and bad and if you were good and true, you would wait to have sex until after you were married, and then only with your husband. Otherwise, if you had sex before you were married, you would get Pregnant, and have a baby, and everyone would know what a bad girl you were, and think that your baby was bad too, and you would have to take care of the baby all by yourself and the baby would cost a lot of money that El didn't have. And if you got Pregnant you had to keep the baby, because Abortion was an even worse Sin than Unmarried Sex and you would become a murderer and go to Hell.

El knew she was already a bad person for having sex with Mike, and she knew that having a lot of unprotected sex would lead to having a baby too, on top of all of that. It was fine that she was soiled, that she hadn't been strong enough to resist Mike, deep down she knew she had always been an undeserving person, it was why bad things had happened to her, it was why Papa had treated her so badly and why her Mama had gotten sick and why she had become an orphan, but she didn't want to bring a baby into the world that people thought was soiled too. She didn't want to have a baby that she couldn't take care of, so that the baby ended up just like her – an unwanted, unloved orphan, a weirdo, a freak ….

All of these things had been running through her mind, and it was why that night, El couldn't seem to fall asleep. After about 2 hours of tossing and turning, she figured it must have been about 2am, and got up out of bed with a defeated sigh.

She was alone tonight, she actually hadn't been able to see Mike all day which was a little unusual. That was running through her mind too, why she hadn't seen or even heard from Mike all day, the pang in her chest like she missed him or something, which was stupid, so stupid, like she was some needy little girl, like she couldn't go one day without seeing him, as if she actually really cared about him – after all, she was just his "dirty little slut", and she loved being his dirty little slut, but she hated herself for it, and dammit if she was going to let herself develop feelings for him that weren't just sexual, because he surely wasn't thinking about her as anything other than his play thing.

To get her mind off of things, El decided to take her morning vitamins early. She always took them straight away after she got up so she wouldn't forget.

When they had finally taken her away from Papa and put her in the school, El had had chronic nose bleeds which she had to see the school nurse about. The nurse said she had something called anemia because Papa hadn't been feeding her well (or sometimes at all), so she had given El a bottle of iron tablets and another bottle of generic vitamins that she got refilled every month. Every day she would take the two tablets and since then, she hardly ever had nosebleeds anymore.

El popped the two pills into the palm of her hand and then frowned. The glass of water on her nightstand was empty. She'd have to sneak into the common room for some tap water.

El gingerly pushed the door to her room open and padded out into the hallway. It was so late that El didn't want to push the hallway lights on, for fear of waking anyone up. She was almost halfway to the common room when she got the fright of her life – someone grabbing her by the waist, his other hand clasped over her mouth barely in time to cover up the shout that El gave, dragging her hurriedly back into her room and shutting the door behind them.

El was about to shout bloody murder when she realized in the glow of the light of her room that it was Mike, just Mike.

"Jesus Christ, Mike!" El was breathing hard, still trying to recover from the momentary fright of thinking she was about to get sliced like in a horror movie. "I thought you were a serial killer!"

"Sorry," Mike said, his face looking anything but, smirking at her with mild amusement, "I just didn't want you to scream and wake everyone up."

El was finally starting to catch her breath, her hands over her heaving chest, "What are you doing here? It's late."

"What do you think?" Mike had already closed the gap between them, pulling her by the hips against him, burying his face in the crook of her neck and nipping at her gently, his hands running down her hips to squeeze her ass. "I haven't been able to see you all day," he said, and already she could feel the hardness of his cock through his pants, pressing into her thigh.

"Yeah, been busy?" El was annoyed, but she didn't move away from him.

"Sorry, El," Mike pulled back, looking into her eyes before pecking her lips softly, "This new semester's been crazy. I spent most of today with the team practicing for long distance, and then classes, and then I had to talk to my academic advisor. There's this new chemistry scholarship I'm pretty sure I have a good chance of getting…"

"Oh," El said, feeling relieved and a little stupid. He really had been busy…he wasn't avoiding her. "That sounds great, Mike. I-I'm sure you'll get it. You're so smart. You taught me a lot of things."

He gave her a toothy grin at that, giving her ass another squeeze. "Oh yeah? I sure did…" His hands moved from her ass over to the front of her panties, lightly brushing her sensitive little nub.

"Mike…."

"Look at what you're wearing…fuck. Is this what you wear to bed?" Mike pulled back a little, giving El's body an admiring look.

She had on a little pink babydoll nightie, it didn't have a waistline so it hung loose from her shoulders down to the tops of her creamy thighs. The material was opaque but sheer and Mike could see the dark outline where her nipples were underneath the nightie.

"What?" El hugged her arms around herself self-consciously, which only served to squeeze her round, perky breasts together underneath the nightie. "It's light and loose so its really comfortable to sleep in."

"I'll bet," Mike said, walking her backwards until her knees hit the bed. He sat her down on the edge of the mattress and kneeled in front of her, and before El knew what was happening Mike had his head under her nightie, his mouth suckling her breast, making her nipples pucker and harden as he suckled and drooled on them, while his hand snuck down into the waistband of her panties and begin playing with her clit.

Without thinking, El started to grind her hips up to meet his fingers. It felt so good, and she hadn't been touched by him at all today.

"Oh…oh Mike…." she moaned, as his mouth moved to her other breast, and he stuck in a finger inside her increasingly wet pussy.

He suckled and fingered her for awhile, making her tits and her pussy all wet. Just when El thought she couldn't stand it anymore, Mike pulled back, his head coming back out of her nightie, grabbing at the hem and pushing it up over her head, his other hand pulling out of her slick pussy to pull the panties down her legs and throw them over his shoulder.

She was naked in front of him now, trembling slightly from the chill in the room, her breasts wet with his saliva and her pussy wet with her own arousal.

Without wasting anymore time, Mike shrugged out of his clothes, falling on top of her, pushing her back onto the bed, and started kissing her fiercely, grinding his aching cock against the opening of her slick, tight pussy.

"M-Mike, wait," El said, feeling the tip of his cock begin to rub insistently at her opening, begging for a way inside. "I don't – I don't want to have a baby…"

Mike had his hand around the base of his cock, rubbing the tip of it up and down her pussy, but he stopped at that and grinned up at her, "Neither do I."

"B-But we've been having a lot of sex. A lot of unprotected sex. Maybe we shouldn't tonight."

"El," Mike chuckled lightly, returning to rubbing his cock against her pussy lazily, tapping it lightly on her clit and sending waves of pleasure through her, "We haven't been having unprotected sex."

"We…we haven't?"

"You know those pills the nurse gave you? For your nosebleeds?"

El pushed away from him a little, not sure what to make of where he was going. "How do you know about that?"

Mike sighed. "I should have told you this before but…well, I thought you might get mad at me. Especially before you let me fuck you, like properly fuck you, in that soft, wet little pussy of yours. I paid the nurse to give you birth control pills. They take like, 3 months to kick in, and I knew from the moment I saw you that it was only going to be a matter of time before I'd have you," he said, gliding his cock across her pussy folds for emphasis.

"What? So I haven't been taking iron and vitamins? But my nosebleeds –"

"No, she gave you whatever you needed for that, which was the iron I guess, but I had her tell you the birth control were vitamins."

"How did you – she could lose her job doing that, you know!"

"I made the pay worth it. My family donated a wing of the library to this school, you think I can't afford to pay some of the staff off for favors?"

El had stopped moving or responding to Mike's touches, trying to process this whole thing. Mike noticed, pulling back, suddenly looking as unsure as she had ever seen him before. He was usually so confident and smug. "Are you… are you mad?"

El frowned, letting him stew in a moment of insecurity, he surely deserved it and needed some humbling anyway. Then she hooked her legs around him, pushing his hips forward so that Mike fell flush against her, her soft full breasts crushed against his chest, and giggled, "No, I'm not mad. I'm a little relieved. I was really worried about getting pregnant."

Mike's look of concern turned into something darker, and he grabbed her ass roughly, causing El to wince. "You naughty little slut. You had me thinking you were mad at me. That's not nice. I'm gonna have to teach you a lesson."

"Mike, wait.. I haven't taken my birth control for today yet." El glanced over at the empty glass on her nightstand. "That's why I was out in the hallway. I ran out of water so I couldn't take my pills."

Mike glanced at the empty glass too, before smirking down at her. "Don't worry. You don't need to take it with water. I've got something else you can take it with."

"What?" El asked, confused.

"Trust me, and do as I say." He was hovering down over her, tall enough that his body was completely covering El's petite little frame underneath, dominating her. She was completely helpless under him, and the thought made her pussy so so wet.

El let out that little whimper-moan she knew he liked, biting her lip and nodding her head up at him obediently. It was almost like a green-light signal for Mike, because as soon as she did it he thrusted into her in one brutal stroke, completely sheathing his cock in her tight, slick pussy.

"Ah!" El barely had time to cry out as he immediately begin pounding into her, long, hard strokes that shook El's entire body as she took his cock fully into her tight, inexperienced hole over and over again. It hurt so good, her body still getting used to Mike's big cock stretching out her pussy lips, still getting used to his cock inside her tiny little virgin slit.

Mike wrapped his fists painfully around each of El's thighs, pushing her legs all the way up and down against her body so that she was almost folded in half underneath him. He hooked his arms underneath her knees to keep her legs there, pushed so far up against her body that her ankles were pressed down around her head with the weight of his body crushing her own.

Then, he really went to town.

His cock started pounding into her small, aching pussy ruthlessly, hard and fast, squeezing the breath out of her lungs with each merciless thrust and causing her tiny little bedframe to shake and bang against the wall. With her legs splayed up against her body, her hips angled so that her pussy was wide open to him, taking him in as deep as he could go. He bottomed out each time he hammered into her, hitting her cervix over and over again. El was squirming and crying underneath him, the pain was so good, he was filling her up and stretching her out, and he would make her pussy so sore and swollen.

They had agreed on a safety word over Christmas break (Eggos), when they started to realize that a little bit of pain made El wet and causing El a little bit of pain made Mike hard, and even though El was crying underneath him, tears falling down her cheeks as he battered his cock into her helpless pussy again and again, she hadn't said it, so he kept going.

"You like that, huh? My cock is ruining your tight little untouched pussy, El. It's taking in so much cock and its never had to take cock before. But you love it, because you're so dirty and cockhungry for me, aren't you? Fucking say it, El! Say you're my dirty little slut and you love ruining your pussy on my cock."

El could hardly talk, squished underneath Mike's hard body, her entire frame being rammed into the mattress hard and repeatedly, her words coming out in stutters as she continued to shake with the force of Mike ramming his cock in and out of her tight and sore little slit, having no choice but to take it, "Y-Yes! I'm your dirty little slut, Mike, you're dirty little virgin that you ruined. I love taking your cock so much I let it ruin my inexperienced young pussy, it always has to take so much of your big cock it's stretching my hole out…"

"You love getting fucked by my cock so much you were going to let yourself get pregnant, weren't you? Your virgin pussy took in so much of my cum…you were so full of my cum it was going to get you pregnant, all round and swollen with my cum like a fucking slut, like a pregnant teen schoolgirl and have my baby, huh? Is that what you wanted? You want my cum to fill you up and impregnate you and get you swollen with my seed?"

His words were so naughty, it was so naughty to have sex and get pregnant and have Mike's baby as a teen, it made her feel dirty and horny, "Yeah, I want you to dump all your cum inside of me and fuck your baby into me. I wanna have your cum and your baby, I was going to be a bad slutty teen mom because I couldn't say no to you, Mike…"

It was everything El had been taught was wrong and sinful and shameful, and she came then, came so hard on his cock as it continued ramming itself deep inside her tight, raw pussy, her muscles clenching down hard on his shaft that was still moving inside her slick hole.

Before she knew what was happening or had even stopped cumming, Mike suddenly pulled out, stroking his cock that was slathered in her slippery pussy juices, "Get your birth control pill, El."

El didn't ask questions, automatically doing as she was told out of habit, it was just the way things were when they fucked.

"Now get down on the floor, on your knees."

Again, El did as she was told, kneeling on the floor. Mike came to hover over her, jerking his slick cock the entire time.

"Put the pill on your tongue and stick your tongue out. Good girl."

Mike jerked once, twice, three more times and then let out a strangled moan as he started cumming, pressing his cock head down on the tip of El's tongue. He spurted copious amounts of his thick, warm cum all over her tongue, burying the birth control pill on her tongue in ropes of sticky white cum.

"Oh fuck…." Mike was panting harshly, his dick still gripped tightly in his fist, "Now swallow it, El. Swallow your birth control with my cum."

It didn't go down as smoothly as water, but El could barely feel the pill go down her throat past the gooey feel of taking in his cum. "Mmm…" she sighed, dreamily, licking her lips as she swallowed every last drop of cum with her birth control. "Yum."

From then on, El always swallowed her birth control pills down with Mike's cum.

A/N: I know that you usually take birth control pills every day, which is a little unrealistic to think she'd do this every time she took them, so just imagine they're birth control pills that you take once a week or something lol
