The boy next door

Luke finds out

I opened the door and pulled Calum inside.
"Are we alone?" He asked, attacking his lips to my neck.
"I think so." I breathed, closing my eyes as I felt Calum biting at the skin on my neck.
"Good." He hummed, gripping my hips.
"Is that you, Y/N?" Calum and I quickly moved apart as Luke walked into the living room.
"Oh hey, Calum." He smiled.
"Hey mate." He gulped. Luke looked at us.
"Why do you guys look so nervous?" He chuckled.
"No reason." I shook my head. He nodded slowly.
"Right. Well, I'm going to watch TV, what are you up to?" He asked.
"Why would we be up to anything, why would you even assume that?" I rushed. He looked at me in confusion.
"Y/N, I meant are you studying, are you hanging out, what." He scoffed. My mouth formed into an o as I looked at Calum.
"We're studying." Calum nodded.
"Right. Well, I'm watching TV." He mumbled before sitting down. I gulped and grabbed Calum's hand before rushing up the stairs.

"Baby, I need you." Calum mumbled against my neck.
"Luke is in the other room." I sighed as he rolled on top of me and continued his assault on my neck.
"I'll be quiet." He mumbled.
"It's not you I'm worried about." I chuckled. He looked up at me and smirked. He sat up and pulled his top over his head. I sat up too, placing my hands against his stomach and chest, knowing that was one of the things that turned Calum on. I looked up at him and smiled as I saw him trying to suppress a moan.
"I never get tired of seeing you like this." I spoke.
"What, getting weak at the knees because of you?" He spoke, though struggling to get the words past without letting his moan slip too.
"Exactly." I smirked. He returned it as he lifted my top over my head.
"You're such a fucking tease." He smirked before joining our lips again and pushing me back down on my bed. He moved his kisses down to my neck and sucked on the skin, causing me to arch my back into his chest at the feeling of him leaving his mark on me. My breath started to quicken as he moved a hand down my chest and stomach before carrying it down to the waist band of my shorts. I tried to suppress a moan as he pulled them down slowly, leaving me in just my underwear and bra. He continued to suck on my neck as he pushed the fabric of my underwear to one side and slowly pushed a finger inside of me. My breath hitched and my back arched off the bed at the familiar feeling.
"Calum..." I moaned as he curled his fingers.
"God, the things you do to me." He moaned into my neck.
"Y/N, mum wants to-oh my fucking god!" Calum quickly removed himself from me and rolled off me to reveal Luke standing at the doorway. I gulped as I grabbed my bed covers, covering my barely clothed body with them.
"What the fuck did I just see?" Luke spat. Calum and I looked at each other.
"Um...er....um..."
"Calum, you're so fucking dead." Luke snapped before lunging towards us. Calum and I shot up and I stood in between them.
"Luke, calm down." I spoke.
"Are you kidding right now?! I've just caught my little sister and my best friend about to fuck, why the hell would I calm down?!" He hissed.
"Mate, please-"
"No, Calum, you don't get to call me that!" Luke yelled.
"What-what do you mean?" Calum stuttered.
"What, you don't actually think we're still going to be best friends after I've seen you about to screw my sister?" Luke scoffed.
"Come on man-"
"Get out." Luke cut him off. Calum's eyes widened further.
"You what?" He scoffed.
"You heard me, get the fuck out of this house!" He yelled.
"Luke, please." I choked.
"No, it's okay." Calum nodded as he pulled his top back on. I looked at him.
"No it's not okay, this isn't his relationship." I shook my head.
"Calum, you have thirty seconds to get out of this house before I fucking kick you out." Luke spat.
"Luke, don't do this." I choked. Luke gestured towards the door. Calum sighed and gave me a small smile before leaving my room and leaving the house.
