"Oh my god." Joyce clutched Will to her chest as soon as she saw his face. "What happened to you, baby?"

"Troy." Elle answered for him, walking past her mother and setting her bag on the table with a thud. "Assbutt." Joyce didn't even correct her language, too concerned with fixing up her son.

Elle stood in the kitchen, still fuming. She wanted to break something, to burn something, to do something. An idea popped into her mind.

"I'm going to Mike's!" Elle called out to the house. She dashed upstairs for a minute, and then was out the door.

"The hell is going on here?" Hop woke up from his nap on the couch.

"The kids went to the library, Will got hit, Elle took out the jerk, and now she's going to the Wheelers." Joyce summed up. A thin wail broke through their conversation and Hopper sighed.

"Okay. I'll go get the baby."

"When will your parents be home?" Elle walked into Mike's room with a determined expression on her face. Mike looked up from his homework in surprise. They hadn't made any plans for tonight. Unless he had forgotten. God, did he forget?

"What?" He asked, confused as she pulled her shoes off and tossed them to the side.

"They aren't here now, so when will they be back?" Elle started unbuttoning her top and Mike dropped his pen. What was she doing?

"Um, 9, I think? They went to see some concert in the city. Holly's at Grandma's because they wanted me to be able to…. to s-study." Mike's words trailed off as Elle yanked off her shirt.

"What are you doing?" He asked as she walked over to him. "Elle?"

"I wanna sex." She stated. Elle sidled up to him, laying her head on his chest. Mike focused on his breathing. Holy god, this was not seriously happening. Had he fallen asleep while studying? Maybe this was some sort of wet dream. That would be really weird though. This wasn't exactly the most common porn scenario.

"Mike?" Elle tilted her head up to look at him. "Do you… do you want to?"

Mike released a breath. "Hell yeah."

Their mood changed almost instantly. Elle's arms wrapped around his neck as she kissed him fervently. Mike hoisted her up to sit on his lap. He ran his hands down her arms, reveling in the feeling of her smooth skin.

"Mike." Elle whispered as he struggled to unclasp her bra.

"Yeah?" He squeaked, tugging at the fastenings. Dammit, he just wanted to see her boobs already. Why was this so hard? Did girls sleep in these or something? How did they get them off?

"Mike, I got it." Elle stood up and took it off herself. Mike couldn't think straight anymore.

Elle sat on his bed and pulled her tights and skirt off, Mike's eyes stuck on her. Oh god. Elle was in his room, his room, in nothing but a pair of pink lace panties. His gaze roamed over her body, taking in her generous breasts, lightly rounded stomach, and well-muscled legs. Mike had a new appreciation for basketball.

"You too." Elle gestured to him. "I want to see."

"Oh, um right." Mike fumbled with his belt, painfully aware of his embarrassingly eager erection.

"Let me." Elle knelt in front of him and undid it, unbuttoning and pulling his pants down carefully. Mike shuddered at the sensation. Elle looked up at him.

"Can I touch it?" She asked innocently.

"Do you…" Mike swallowed. "Do you want to?" Elle nodded.

"Abigail said it feels really good for boys. She told me lots. She knows, because of-"

"Please don't talk about Dustin and Abi." Mike begged. Elle pulled his boxers down and grabbed his dick. Mike inhaled sharply. Wow.

"Is this okay?" She asked, gently stroking him.

"God yes."

"This?" Elle placed her lips around him and Mike groaned. She started to move her mouth around him, but Mike stopped her.

"No, no, no." He pulled her up despite the throbbing of one of his more insistent body parts.

"Did I do something wrong?" Elle looked hurt.

"No, that felt fucking awesome. But I want to you know, do it with you."

"Oh." Elle flushed a little, despite having had his penis in her mouth just a few seconds ago. She shifted a little, trying to relieve the tension she felt in her stomach.

"Just a second." Mike released her to rummage in his drawer, emerging with a condom that he quickly slipped onto himself. He took Elle's hand and pulled her back to him, moving his mouth with hers in a way that made Elle positively burn.

"Mike." She whined, rubbing her thighs together. He backed her up against his bed, moving his mouth lower to kiss her neck. His hands brushed down her chest and around her nipples, causing her to shiver.

"May I?" His hands stopped at the edge of her panties.

"Please." Elle breathed. The burning feeling was getting stronger. She needed something to make it stop.

Mike pulled the pink lace away from her and swallowed thickly at the sight.

"Jesus, Elle." He licked his lips before tentatively touching her. Elle let out a moan that startled them both.

"Sorry." She flushed crimson.

"No, it's fine. That's normal. Well, that's what I read." Mike reassured her, beginning to move his hand.

"Mike." Elle panted.

"Yes?"

"You're a nerd. Now please sex me." Elle scowled at him. "I need it."

"It might hurt." Mike warned her, crawling over her on the bed.

"Do it." Elle commanded, arms above her head and hair pillowed out around her face.

Mike slowly pushed into her, trying not to go too quickly. Elle gasped slightly, scrunching her eyes up.

"Do you want me to stop?" Mike froze, trying not to groan at the incredible feeling of her.

"No." Elle managed. It hurt, that was certain, but the fire in her stomach and lower was even more intense.

Mike finished pushing in and began to pull out. This time, Elle felt much better. By the fourth time, she started to breath quickly. God, this felt good. If she was going by Mike's face, he felt the same way.

"Can I… can I go faster? Elle?" Mike asked breathlessly. She nodded.

"Please Mike." He sped up and she started to feel herself reaching the edge of a cliff as he suddenly let out a groan and stopped moving. Elle opened her eyes.

"Mike?" She whined as he pulled out of her. Why was he stopping? Mike opened his eyes, his face a bright pink.

"I'm sorry Elle. I didn't think I'd, uh, finish that quickly. Uh, I know what I can do." He laid down in between her legs.

"Mike?"

"Shh, let me try this." He gave her a tentative lick and Elle practically jumped. Fuck, that was like all the good feeling from earlier bundled together. A few licks and sucks later and Elle was back on top of that precipice.

"Please Mike, please." She begged, not even entirely sure what she was asking for. His lips fastened around a certain spot and Elle screamed as her orgasm came crashing over her.

A minute later, after the trembling had stopped and Mike had discarded the condom, Elle laid her head against his chest, feeling the happiest and most content she had ever felt.

"I liked that." Elle yawned. "Let's do it again soon."

"Hell yeah." Mike agreed. He was definitely up for that.
