Chapter Four: One Rule

Katie woke up to the sound of Steve mumbling soft, incoherent words. She glanced over to see him passed out beside her, his arm draped over her torso, securing her body against his. She smiled to herself, shaking her head. Damn, she never thought she'd get to sleep with Steve Harrington. Well...more like next to Steve. He seemed like a genuine guy; he didn't immediately want to get in her pants, he actually wanted to get to know her first. Steve had also opened up to her way more than any other male ever had. Nancy definitely changed him, that's for sure. What was so special about her? Sure, she was pretty and could be decently nice, but what about her drove him crazy?

Steve began to stir in his sleep, jolting his head and twitching his face. It looked like he was having some sort of nightmare, he was thrashing around and mumbling louder.

"No, Dustin, get behind me. Damn demodog," Steve murmured angrily. What the hell is a demodog? Dustin? As in the middle schooler that Steve babysits? Katie debated on whether or not she should wake him up, and she decided that his rambling was quite entertaining, therefore, she was not going to wake him just yet. She slowly sat up and untangled herself from his arms so she could stretch out. Damn, she thought as she rubbed her neck, he is one fierce cuddler.

"Dustin, no, don't put it in the fridge, Mrs. Byers will not like that…" Steve slurred, and then rolled over closer to Katie. Mrs. Byers… as in Jonathan's mom? What was he doing dreaming about her? Katie had met her just once before, and as nice as Mrs. Byers was, she was a little kooky. But then again, if Katie's son had disappeared for a while and was presumed dead, then yeah Katie would be a little peculiar too. What the hell was Steve dreaming about? She decided that she should wake him up, especially since it was almost midnight and she didn't know how strict his parents were. Her parents were away on vacation, which is why she didn't kick him out earlier.

"Hey, Steve?" She said as she lightly shook his shoulder. He groaned and turned away from her. She smirked and reached for the lamp on the table next to them and turned it on. He moaned and flipped over onto his stomach so that his face was shielded from the light.

"Dude, it's midnight. I'm not sure how your parents are but I don't think they'd like you coming home after twelve." She said softly, putting her lips beside his ear. He slowly sat up, rubbing the sleep from his eyes.

"They're away," He said quietly, "I have the house to myself." He then looked around and realized that he had no clue where her parents where.

"Oh, no, they're gone on vacation for the next couple days. I'm alone." He smiled and reached out to hold her hand.

"Are your parents usually gone?" He asked gently and began rubbing circles on her hand with his thumb.

"Sometimes," she shrugged, "my mom works a lot, and when my dad does work he's out of town for a couple days." He nodded and gave her a knowing look.

"My folks are always gone," he said while he turned his attention towards his hands, which were both encasing Katie's right hand. "they are just so obsessed with one another, mostly jealously, that they tend to forget me."

"I'm sorry. That really sucks. How often are they gone?" She questioned. He shrugged and stared blankly at his hands.

"I dunno, probably a couple times a month for three or four days." She slid her hand out from underneath his and laid back down beside him, their faces nearly touching. He smiled gingerly at her and put his hand on her face, cupping her cheek. His hands were rough and almost tickled her face, she giggled when he began to stroke her cheek bone.

"It sounds like they're out of town more than in," She stated, and wrapped her arm around his waist, pulling him closer to her. He nuzzled up to her and sighed.

"Yeah, they are. It can be pretty cool, I used to have parties and stuff…"

"What do you mean used to? Why don't you anymore?" Steve blushed and seemed embarrassed.

"Well," he had moved his hands away from her face and was shifting uncomfortably. "it's kind of hard when you don't have anyone to invite."

"I'll come," Katie said and reached for his hands, settling them on her sides. She reached out and ran her fingers through his hair. It was tacky and tough, and she almost immediately pulled her hands away and tried to nonchalantly cup his face. He laughed and shook his head, knowing how unsettling his hair felt.

"Really?" He asked her with these big brown puppy dog eyes. Instead of replying, she kissed him roughly. He kissed her back with passion, pulling her closer and running his hands up and down her body. She was definitely not wearing a bra. He slipped her hands under the bottom of her shirt and waited for a physical cue for him to continue. She shifted her chest closer to his, essentially begging him to keep going. He made his way up her torso and softly cupped her breasts; they were a nice handful. He began to tenderly squeeze them as she moaned into his mouth. Katie's hands slid under his shirt and made a tugging motion, implying that she wanted it off of him. He immediately complied, whipping his shirt off in one fluid motion, barely even pausing their kissing. She decided that it was only fair that hers came off two, so she pulled her tank top off and watched as he stared at her.

"What?" She asked, worried that something was wrong. Steve blinked at her, unable to take his eyes away.

"You're just, goddamn, you're gorgeous." She blushed and giggled a little. He smiled and pulled her off of the couch. He embraced her and whispered, "is there somewhere we can go that's a little roomier than the couch?"

She smirked and replied, "My bedroom is upstairs." She grabbed his hand and led him up the staircase, grinning the whole way.

Once they got to her room they wasted no time. Steve pulled off her pants and caressed her thighs lightly, which made her giggle. Katie helped him undo his own jeans and threw them in the corner before hopping into bed with him. They snuggled under the covers, exploring each other's body with their hands. He kissed her with desire and lust, getting rougher and rougher with every minute. She matched his energy and yanked off his boxer briefs before pulling down her own panties. Steve pulled away so that he could admire her.

"You are fucking beautiful." He breathed, and then went straight for her neck, sucking harshly. She moaned and moved her hand above his dick, waiting for a response. Steve thrusted his hips forward, meeting her hand. She grasped him and began to slowly move her hand up and down. He moaned into her neck and subconsciously grinded his hips into her. Katie decided that she simply couldn't take it anymore.

"Steve, I need you." She moaned. He stopped kissing her neck and looked up at her, his eyes questioning.

"Are you sure?"

"Yes." With that answer he slowly moved his way on top of her and spread her legs, caressing her face the entire time. He looked at her again, and she nodded, biting her lip in anticipation. He entered her and she moaned, arching her back. Steve kissed her lightly, then waited to make sure she was okay.

"Just fuck me," she said bossily. He smirked and shrugged his shoulders.

"Okay, but you asked for it." He began to rhythmically thrust into her, causing her to yell out in pleasure. He went faster and faster, causing the bed to shake back and forth. Steve brought his hand down and began to massage her clit, which made her scream his name. After a few minutes Katie was shaking from orgasm, trying to catch her breath. He was not far behind, and spilled out onto her stomach.

"Oops," he grinned at the mess he made. She laughed and told him to go get some toilet paper from the bathroom. He cleaned her up and kissed her forehead lightly.

"Should I go?" he asked, feeling uncertain about spending the night with her. She just laughed at him and patted the space beside her in the bed.

"No, but I only have one rule." She said, smirking at him.

"Oh, what's that?" Steve questioned while climbing into bed.

"We sleep naked."
