Requested by pennywinkle0112: Y/N is Harrison's sister, and her and Tom hate each other, but also always tease each other.

"I'm home!" I yelled as I shut the front door.

"Tom's over!" Harrison shouted back, making me sigh and close my eyes.

"Awesome." I mumbled, mentally preparing myself for facing the asshole as I headed into the living room. My brother and his best friend looked up at me as I walked in, Tom rolling his eyes before he looked back at the TV.

"Good to see you too, dickhead." I scoffed, him just flipping me off in response as I shrugged my jacket off. I was Y/N Osterfield, Harrison's younger sister by a year. My brother and I got on well enough, but I only wished that I could say the same about his best friend, Tom. It sucked because the twenty-four-year old was hot as fuck, and was really nice on the rare occasion that I'd seen him be nice. But for some reason, he loved just being a dick to me, and had even started to tease me with little touches and "accidental" brushes in the last year or so. The sexual tension was building steadily, but I wasn't sure yet if I wanted it to ignite.

"Would it kill you two to just get along?" Harrison sighed.

"I'm not the problem here, Haz, he is." I nodded, making Tom roll his eyes as I started to head into the kitchen.

"You wish, love." Tom scoffed. It was my turn to roll my eyes as I headed to the fridge and opened it. I sighed and bent down, my eyes skimming over the contents as I tried to find something to eat.

"Watch." my eyes widened as Tom spoke, his hands placing themselves on my waist as he moved past me. I immediately stood up straight and looked at him, my cheeks burning and my eyes wide as he grabbed a glass and headed to the sink.

"What the fuck was that?" I scoffed, apart from something that I very much enjoyed, I also thought to myself. Tom looked at me over his shoulder.

"What was what?" he mumbled.

"That. You putting your hands on my waist." I spat.

"What, you didn't enjoy it?" he teased, his eyebrow raising as he leant against the counter and took a sip of his water. I clenched my jaw at him and tried desperately not to blush at his words.

"It doesn't matter if I enjoyed it or not. The point is that you didn't need to put your hands on me to move past me." I snapped through gritted teeth. In reality, I didn't mind what he'd done at all, but things would become extremely awkward if he knew that I wanted to fuck him.

"I did because your arse was sticking out, and so was in the way." he nodded.

"You could have easily gotten past." I scoffed.

"Maybe I could have done. Maybe you didn't want me to get past without touching you a little." he shrugged. My eyes widened at his words.

"What?!" I exclaimed.

"Maybe you were trying to tease me, love." he smirked.

"Why the fuck would I want to do that?" I spat. To make him fuck me.

"Well, because you know what I want to-." he stopped himself from talking, his eyes wavering as he looked down. My eyes widened slightly, my heart jumping at him stopping himself. He wanted to what?

"Finish your sentence, Tom." I demanded as I walked to him. He gulped, his jaw clenched as he looked up at me.

"Fuck you." he spat.

"Fuck you too, Tommy, finish. Your. Sentence." I snapped back.

"No, fuck you-."

"Finish the fucking sentence-."

"You know that I want to fuck you." he spat as he grabbed my hips and turned us around so that it was now me pinned to the counter. My eyes widened, my breath hitching in my throat as he said that. He scoffed and shook his head as he clenched his jaw.

"You happy now?" he snapped.

"Very." I nodded. He scoffed again before grabbing my face. My eyes widened as he leant down and smashed our lips together, but I returned the kiss immediately as my hands raised to cup his face. He curled his hand around to my neck and pulled me closer, making me breathe out against his lips as he slipped his tongue into my mouth. Suddenly, his eyes shot open and he broke the kiss before darting away from me.

"Fuck, shit, I'm sorry, I shouldn't have done that. Please don't tell Haz." he gulped as he rubbed his hands over his face.

"No, I won't, I kissed back. Fuck." I sighed and shook my head before looking at him. He returned the look, his Adam's apple bobbing in a gulp.

"Fuck it." he mumbled before rushing to me again. He took my face into my hands and smashed our lips together, me returning it immediately as I raised my hands to his face too. His hands moved to my waist and pulled my hips against his, his lips letting go of a moan against mine as I tugged at the hair at the nape of his neck. I broke the kiss and looked at him.

"We can't continue this here, Harrison is too likely to come in. I'll go upstairs, you tell him that you need the bathroom or something and then meet me in my room." I nodded, making him return it as he joined our foreheads.

"Do you have condoms and stuff?" he mumbled.

"Bit presumptuous, Tommy." I teased.

"Oh, please, darling, we both know where this is going." he returned, making me smirk and lean up to kiss him again before pulling away. I gulped and tried to recompose myself as I headed out of the kitchen and into the living room. Harrison looked at me and his eyebrows furrowed.

"You okay, Y/N? You look a little flustered." he spoke. I gulped and looked at him as I grabbed my bag and jacket.

"I'm fine." I shrugged before heading upstairs. I rushed up, my heart pounding in my chest as I rushed into my bedroom. I threw my stuff down and quickly opened my drawer, knowing that I had to change into some more sexy lingerie if I was about to fuck Tom. I threw my clothes off and replaced my underwear, knowing that Tom wouldn't be able to resist me like this. Even if he did actually hate me. I got dressed again and tried to compose myself as I sat on the end of my bed and waited for the boy to arrive. As if on cue, I heard rapid footsteps coming up the stairs, making me smirk and bite my lip. He appeared at the doorway and gulped before looking back down the stairs to make sure that we hadn't aroused Harrison's suspicions.

"This is a bad idea." he shook his head as he walked in and closed the door before locking it.

"Leave then." I shrugged as I stood up and walked to him.

"Fuck no." he scoffed before leaning down and kissing me again. I returned it, my hands holding his face as his hands gripped my waist. He slipped his tongue into my mouth, him quickly initiating a make-out session between us as we started to stumble towards my bed. I pulled at the bottom of his t-shirt, the boy quickly getting the message as he broke the kiss and pulled the garment off before immediately capturing my lips again. I squealed into the kiss, making him smirk as his hands pulled on my thighs and he lifted me up. Our lips stayed together, our tongues and teeth clashing the whole time as he lay me down on my bed before crawling over me.

"You're so fucking hot, babe." He mumbled as he broke the kiss and moved his lips down to my neck. I smirked at his words, my eyes fluttering shut as he left open-mouthed kisses on my skin.

"Tommy, we have to be quick so that Haz doesn't find out." I breathed, the boy kissing down to my collarbone as his fingers started to undo my top.

"I don't care, babe. I want to taste you." He spoke as he continued to kiss down my collarbone. I couldn't help but moan at his words, making him smirk and look up at me as he unbuttoned my top to reveal my bra. His eyes widened slightly.

"Fuck..." he mumbled, making me smirk and bite my lip.

"You like what you see, Tommy?" I teased as he continued to kiss down my body, his lips trailing down the valley of my breasts before starting to kiss down my stomach.

"I love what I see, babe." He admitted, my smirk widening as he kissed down to my shorts. My breathing started to jagger, my eyes glued to him as he undid the button and zip. He pulled my shorts down, another moan leaving his lips as he saw my thong. He looked up at me.

"Did you plan this, darling?" He scoffed accusingly.

"I didn't plan it, but I may or may not have changed my underwear just before you came up." I admitted. He smirked and shook his head as he pulled my thong down.

"You'll be the death of me, angel." He nodded before leaning down and attaching his lips to my clit. I gasped, my eyes squeezing shut and my back arching off of my bed as my hands pulled at his curls.

"Fuck, Tommy." I choked, my legs hooking over his shoulders as he started to eat me out eagerly. He curled his arms around my legs, his hands landing on my stomach as he did. I bit my lip harshly, my fingers tugging at his curls as his lips sucked at my clit and his tongue dipped in and out of me.

"Tommy, Jesus." I moaned as the knot already started to build up.

"Be quiet, babe, don't want Haz to hear you." He cooed against my clit. I smirked and shook my head, my mouth hanging open as I continued to roughly pull at his curls. He moaned into my clit at the action and only added to the pleasure that I was feeling.

"Fuck, I'm so close." I choked as the knot got unbearably tight.

"Cum for me, darling, cum for me." He encouraged. I bit my lip harshly, my eyes squeezing shut and my legs starting to shake as the knot broke. My orgasm hit me, quiet moans and calls of Tom's names leaving my lips as I harshly tugged on his hair and my legs shook against his shoulders. I panted heavily, a thin layer of sweat now glistening against my skin as he removed his mouth from me.

"Wow." I spoke simply, making him smirk as he crawled back up my body.

"That good, darling?" He teased.

"Very." I nodded as I grabbed the back of his neck and pulled him down to kiss him again. He returned the kiss and smirked into it, his fingers moving down and starting to unbuckle his belt as we continued to make out. He gently pulled his now hard dick out of his jeans as I grabbed a condom and ripped it open with my teeth before taking his dick into my hand.

"Fuck." He moaned, his eyes fluttering shut and his head falling to my neck as I started to gently pump him.

"Please, babe, don't, I just want to fuck you." He scoffed and shook his head. I smirked and bit my lip, him returning it as he pressed kisses to my neck and I rolled the condom onto his dick.

"You ready, angel?" He mumbled into my skin.

"Please, Tommy." I nodded. He returned it before starting to gently push into me, quiet sighs and moans leaving our lips as he did.

"Oh, you feel incredible." He moaned.

"Tommy, move." I choked. He nodded and pulled almost completely out before slamming back into me, making me cry out at the feeling. He picked up that pace, his thighs starting to slap against mine as he fucked me harshly. I pulled on his curls, making him moan into my neck as he continued to place sloppy and open-mouthed kisses against my skin. That added to how harshly he was pounding into me was making the knot already build up again in my stomach.

"You feel amazing, love." He grunted into my neck.

"So do you, don't stop." I shook my head. He returned it and raised my leg to wrap it further around his waist, making me squeeze my eyes shut as the new angle allowed the boy to get even deeper into me. The sound of our quiet moans plus our skin slapping together bounced off of the walls, the room smelling of sex as Tom fucked me into next week. The knot got tighter with every thrust, and at the pace that he was going, I wouldn't last long.

"I'm not going to last much longer, darling, fuck." He moaned.

"Neither am I, Tommy, I'm so close." I admitted. He nodded before leaning up and smashing our lips together again. I returned the kiss, my hands curling around his neck and pulling him closer as he slammed into me. His pace, plus the kiss, pushed me over the edge.

"Tommy!" I moaned, my legs shaking around his waist as my second orgasm hit me like a truck.

"Christ, sweetheart." He choked, his eyes squeezing shut and his body stilling as he filled the condom. We panted heavily, Tom's hips starting to thrust again at a slower pace in order to work us both through our highs before he stopped. I gulped, my mind and heart racing at what we'd just done as he collapsed on top of me. He rolled off of me and onto the spare side of the bed, making me look at him as he panted heavily.

"Wow." He chuckled, making me smile and bite my lip as he pulled the condom off and binned it before looking at me.

"Yup." I nodded.

"We really just had sex." He stated.

"Yeah, we did." I chuckled. He looked at me.

"So...you don't hate me after all?" He asked hopefully.

"No, I do. That was purely hate sex." I teased, making him playfully roll his eyes and roll onto his side so that he was facing me.

"What do we tell Haz?" He asked as he curled his arm over my stomach and pulled me closer. I sighed and bit my lip.

"Depends on what happens now. Is this a one-time fuck, or are you going to ask me out?" I asked quietly. He bit his lip.

"I'm going to ask you out." He admitted. I smiled at him, making him return it as he leant in and gently pressed our lips together. I returned the kiss and cupped his face before breaking it and looking at him.

"I think that we better tell Haz, then." I nodded.

"God, he's going to kill me for shagging his younger sister." He groaned as we sat up.

"Just take me out somewhere really nice for our first date and I'll make sure that he doesn't." I teased, making him smirk and nod as he kissed me again.
