"What did you get on the last test?" I wondered, watching Derek struggle over his calculus homework with the end of his pencil between his teeth. With everything going on, both of us admitting our feelings and now trying to figure out how to be in a relationship together, I hated to admit that I had been slacking on his studying. He had missed three homework assignments and didn't study for the last test and I felt like it was all my fault.

Derek cringed, taking the pencil out of his mouth to frown at me. "A thirty-two," he admitted, his face red with embarrassment. "But I can retake it, I just have to study after school for two days before hand. Monday and Tuesday, I scheduled time in the study hall. Maybe you could pull some strings and be the one who tutors me?" he asked, leaning towards me so his shoulder pressed against my leg. I was sitting on my bed overseeing his studying while he laid on his stomach with the work splayed out in front of him.

"I'll see what I can do," I promised, gently pushing his face back towards the papers. "Here's the deal. If you can do fifteen of these practice questions and get them all right, I'll ask my dad if you can stay over tonight," I said, watching his face light up. It had been almost a month since we started officially dating, and after the incident at the mall last week, we'd been spending a lot more time together than usual. The truth was that I'd let him stay the night no matter what because I just wanted to be close to him for as long as possible.

"Am I allowed to ask for help?" he whined, pouting as he stared at the menacing calculus questions in front of him.

I laughed, running my fingers through his hair before getting up to sit at my desk instead. It would be less of a distraction for him if I was farther away. "You get three questions, so use them wisely," I teased, making him groan. While I sat across the room from him, he worked in silence, trying his best to figure out the problems on his own. I watched him fondly, smiling every time he made that adorable thinking face, or when he chewed on his pencil, or when he sighed at himself for making a small mistake. It was crazy to me how much I had changed since admitting to myself that I liked him. I used to be hung up on a girl who would hardly look at me, let alone make my heart swell as I watched her do math problems on my bed. Derek Hale was a huge surprise in my life, but a very appreciated one. I didn't think I could love someone more than I loved Lydia Martin, but as it turned out, that wasn't love. This was. Derek and I weren't perfect by any means, but I wanted to spend the rest of my life with him. That's how serious I was about him.

"I did it!" he announced, interrupting my thoughts about him as he sat up, a smile across his lips. "I think they're right, anyways," he added, his face suddenly red at the thought of being wrong. He got up from the bed, bringing his paper over to my desk. I spun my chair to face my desk, reading over his answers to check them. I felt Derek leaning over my shoulder, and then his arms around my neck, his lips dangerously close to my ear. I felt my face flush red, but I ignored that and kept focusing on his paper. "So, how'd I do?" he asked, eagerly.

"You got one wrong," I told him, looking up in time to see his expression falter, a frown replacing his smile. "But, you didn't ask for any help, so I think you still deserve a reward," I said, hoping to cheer him up again. I shoved his paper into his notebook, closing it so we could move on to something other than calculus.

Derek smirked, his teeth gently sinking into the skin behind my ear, teasing me. "A reward, huh?" he breathed, his soft words sending a shudder down my spine. He worked his rough hands from my shoulders down my chest, slowly hiking my shirt up so he could feel my bare skin against the warmth of his fingers. "Do I get a say in this reward?" he coaxed, his wandering hands igniting my skin with every touch.

I let out a shaky breath, my face red and extremely hot, even without looking at Derek. "Y-You can have whatever you w-want," I faltered, biting my lip hard as he turned the chair to face him, where he was suddenly on his knees, positioning himself between my knees with a sly grin on his face.

He chuckled softly, probably amused by how much he still made me blush, even though we had done things like this a couple of times already. I would never get used to the way he talked to me, making my heart thump against my chest, my stomach flutter, and my entire body feel like it was on fire. "I love it when you get all flustered like this," he teased, pulling me into a kiss by the front of my shirt. No matter how many times he kissed me like this, it would always make my heart skip a beat. His grip on my shirt gradually loosened as his fingers gently tracing the curve of my neck, moving to cup my cheeks to deepen the kiss. I gasped as his teeth sank into my bottom lip, making the heat in my body somehow even hotter. I wanted to be even closer to him, so as his hands gently tugged at the hair near the back of my neck, I grabbed his strong shoulders, using him as an anchor to pull myself out of the chair and into his lap.

"I need more," I panted, straddling him as he smirked, his hands moving to squeeze my waist. Just as he slipped his hands into the waistband of my jeans, I heard the front door slam downstairs, forcing Derek to pull away from the kiss, despite my protests. "D-Derek," I complained, resting my forehead against his.

"Later," he promised, pecking my cheek before easing me off his lap to sit on the floor across from him. "You have to ask your dad about our little sleepover," he reminded me teasingly.

"Well it's going to have to wait a minute," I snapped, gesturing to my tight jeans as Derek chuckled. With a heavy sigh, I got up off the floor and flopped down face first into my pillows on the bed. I felt Derek's weight on the bed next to me, but I ignored him so my problem would go away faster. After about ten minutes, I groaned, dragging myself out of bed with a glare towards my boyfriend. "I'll be back."

"I'll be here," he retorted with that same smirk still on his stupid, kissable lips.

I found my dad in the kitchen with probably his tenth cup of coffee for the day in his hand as he scrolled through his phone at the table. "Hey dad, how was work?" I asked, hoping to gauge what kind of mood he was in so I could ask him about Derek staying over.

He looked up as I sat down beside him, a small smile on his face. "Hey kiddo," he greeted me, thankfully in a cheerful mood. "Work was great. How was school?"

"Good," I answered quickly. "Derek's upstairs. We've been studying calculus since we got home from school," I told him, waiting for his reaction. He usually didn't care about Derek coming over without him being here, but I wanted to play it safe.

Dad hummed, still scrolling on his phone as we talked. "Do you boys want to order takeout for dinner?" he wondered, unfazed.

"Sure," I agreed, deciding now was the best time to jump into the question. "I was also hoping Derek could stay over tonight," I rattled off quickly, hoping he would just agree and move on. Just my luck, this forced him to shut off his phone and look up, our eyes meeting. I swallowed hard, hoping I hadn't just put him into a mood. "We don't have school tomorrow and he has a lot of studying left to do, so I just thought. . ." I trailed off, knowing it was a lost cause if the answer was going to be no.

"You're two teenage boys," dad said, his expression unreadable. I waited for him to explain what the hell he was going on about. Finally, he sighed. "I know what it's like being a teenage boy in love, Stiles. If I let Derek stay the night, just make sure you're aware that the walls in this house are thin and I'm not a heavy sleeper. There are plenty of other opportunities when I'm at work, or-"

"Dad!" I cut him off, my face red with embarrassment. "We're not going to be doing anything like that!" I screeched, wishing he had just said no instead of bringing this up.

"I'm just saying!" he defended himself, as if this were a totally normal conversation. "I can't stop you from doing it. You're almost eighteen, so it's perfectly normal. I just want you to be safe, and also to not do it when I'm home because I don't want to hear it, okay?"

"Not a problem, dad," I assured him, refusing to look at him. "We haven't done anything like that yet and I promise, tonight will not be any different."

"That's good to hear," he said, and suddenly he was back to scrolling on his phone. "But if you have any questions, you know I'm here for you. Even if I have to google it." I had to appreciate that he was trying so hard, but it was more awkward than anything, so I wanted to get away from this conversation as soon as possible. "Derek can stay. I'll order take out," he added, sipping his coffee as if he hadn't just mentioned googling gay sex in order to help me in the future.

"Cool, great conversation, dad," I grumbled, scooting my chair away from the table to get the hell out of there.

When I got back to my room, Derek was working on more practice problems for his calculus test. He looked up when I entered the room, shoving his book to the side. "So?" he asked, raising an eyebrow at my red face.

"He said you can stay," I answered. "Oh, he also said not to have sex while he's home, but any other time is fine," he relayed the conversation, because while it was incredibly embarrassing for me, I knew Derek would get a good laugh out of it.

Sure enough, Derek burst into laughter, shaking his head. "Well, there goes my plan for the night," he teased, not helping my already burning cheeks.

"Shut up," I snapped, falling on top of him as he laid back on the bed. He was still laughing, so I could hear the rumble of his chest as he loosely wrapped his arms around me. At least this way, he couldn't see my face.

After we all ate dinner together, which wasn't as awkward as I thought it would be after dad and I's conversation, Derek and I went up to my room and watched tv for awhile. We tried to play video games, but I got frustrated when Derek kept beating me, so eventually we just went back to watching Netflix, because at least then we got to cuddle. Around midnight, we drifted off, the show still playing in the background. I slept with my head on Derek's chest as he wrapped an arm around me protectively.

A few hours later, I felt my phone buzzing underneath me, where I had apparently left it instead of plugging it in to charge. I sighed, groggily prying myself away from Derek's chest. He grumbled something in his sleep and turned to the side, still out cold. I picked up my phone and saw the time was just past three in the morning. Brett's name was lighting up my phone. I dragged myself from the bed, stepping outside the room so I didn't wake up Derek.

"Brett?" I answered, still half asleep. "What's wrong?"

Brett was quiet for a minute, other than his sniffling, so I knew he was crying. "I need someone to talk to," he said quietly.

"It's late," I replied, forcing back a yawn. "Can we meet in the morning?"

"Well," Brett mumbled, hesitantly. "I'm actually sitting outside your house," he admitted. "I really needed someone to talk to."

I shook my head, wondering if I had heard him correctly. "You're outside?" I repeated, moving towards the front door.

"Yeah," he sniffed. "Can we please talk?"

I sighed, slipping my shoes on as I glanced back at my bedroom door. Derek was sleeping, so I couldn't exactly tell him Brett was here, but I would tell him first thing in the morning. "I'll be right out," I promised.
