(First name is your boyfriend, second name is the band member you cheat with)

Ashton / Calum

Calum smirked as he pulled me into his dressing room and pressed our lips together. I returned it as he gripped my hips, digging his fingers slightly into my skin.

"Ashton is going to kill both of us if he ever finds out." I mumbled, closing my eyes as Calum moved his kisses to my neck.

"Let's hope he never finds out, then." He smirked as he pinned me against the wall.

"Calum, Jesus." I moaned as he bit at my neck.

"Y/N?" Calum's head quickly turned to reveal Ashton standing in the doorway.

"Mate-."

"What is this?" Ashton choked. Calum and I looked at each other.

"Are you cheating on me? With my best friend?" he spat.

"Ashton, I'm sorry." I gulped.

"No, you're not." He snapped.

"She is, mate, and so am I." Calum tried to convince him.

"Shut the fuck up, Calum! How could you?! I'm basically your fucking brother, and you repay me by hooking up with the girl you know that I love?!" Ashton yelled as Luke and Michael ran into the room.

"What's going on?" Luke asked.

"Y/N is cheating on me with Calum." Ashton choked, making their eyes widen.

"Dude, that's not right." Michael shook his head.

"Do you think I don't know that?! Ashton, I'm sorry, neither of us ever meant to hurt you, but we love each other." He spoke.

"No, Y/N and I love each other." He shook his head.

"Don't we, Y/N?" he asked, looking right at me. I opened my mouth to speak but nothing came out.

"Ash, I'm sorry, I really am, but Calum is right. I love him." I admitted. Ashton choked up before rushing out of the room, Luke and Michael following quickly behind him.

Calum / Ashton

I walked into the café and looked around. I smiled as Ashton stood from his table.

"Hey, baby girl." He smiled, kissing me.

"Hey." I smiled as we sat down.

"Calum doesn't know you're here, does he?" he asked.

"No. I told him that I was going shopping." I shrugged, making him nod.

"But I still feel awful. We should at least tell him." I gulped.

"Y/N, you know that I love you but we can't do that." Ashton shook his head.

"Why not?" I scoffed.

"Think about it, babe. Your relationship will end, and there's a very real chance that he won't want to work with me if he finds out, meaning no more band." He sighed. I returned it and nodded. Suddenly, my phone buzzed. I looked down at it and my eyes widened.

Calum: I want your stuff out by the weekend. We're done.

I looked up and gulped as I saw Calum by the window. He scoffed and walked off.

"Shit." I mumbled as I shot up. I rushed out of the café and looked around.

"Calum! Wait!" I yelled as I ran after him.

"Why?! So that you can tell me that you're cheating on me with my best friend?!" he spat.

"I'm sorry." I choked as Ashton appeared beside me. Calum looked at him and scowled.

"Mate, I'm really sorry." He sighed.

"Don't you dare. You shouldn't have to be sorry! You shouldn't be with each other! Y/N, you're meant to be my girlfriend, and Ashton, you're meant to be my best friend. By the way, Y/N, I was going to propose tonight." He spat. My eyes widened.

"But I guess that's not going too happen now." He mumbled, taking a small box out of his pocket and dropping it onto the ground before walking off. Tears left my eyes as I picked the box up and opened it to reveal a beautiful ring.

"Y/N, I'm so sorry." Ashton mumbled as he hugged me tightly.

Michael / Luke

Luke and I lay in bed, our naked bodies wrapped in his crisp sheets. I sighed in bliss as he ran his hands through my hair and I listened intently to his gentle heartbeat.

"I never thought I'd get to say that I've slept with Michael's girlfriend." He chuckled, kissing my head.

"I never thought I'd get to say that I've slept with the one and only Luke Hemmings." I smiled. He returned it.

"So, who's better?" he asked, looking at me.

"At what?" I asked.

"What do you think, at sex. Who's better at sex, me or Michael?" he laughed.

"I'm not answering that." I giggled.

"I'm interested to know too." Luke and I jumped up and covered ourselves with the sheets as we noticed Michael standing at the doorway. Our eyes widened.

"Mate, you weren't meant to be back for another hour." Luke gulped.

"So, you took that opportunity to have sex with my girlfriend?" he spat. Luke looked at me.

"Michael, please let us explain." I spoke.

"I knew it. I didn't want to believe it, but I knew it. I knew that you were sneaking around with another guy, but my best friend? The guy you know is practically my brother?" he choked.

"Mate, don't blame her-."

"Don't worry, Luke, I know that you're just as much to blame." Michael snapped before looking back at me.

"I want you and your stuff out by tomorrow." He mumbled. My eyes widened.

"Where am I meant to go-."

"How about Luke's, you've already jumped into bed with him, may as well take full advantage." He shrugged. I choked at his answer.

"But honestly, I don't care. I just want both of you out." He mumbled before leaving the room. Luke and I looked at each other.

"I'm sorry." He mumbled as he pulled me into a hug.

"Can I stay at yours please?" I choked.

"Of course, babe, of course." He nodded, kissing my head.

Luke / Michael

Michael and I sat on the sofa, tears brimming in my eyes as Luke paced the floor in front of us.

"So, how long has this been going on for?" Luke asked. Michael and I looked at each other.

"About...six months." I admitted. Luke's eyes widened as he stopped pacing and looked at us.

"Half the time that we've been together, you've always been fucking him? Are you kidding me?" he choked.

"I'm sorry, Luke. It just, sort of...happened." Michael gulped, reaching for my hand. I smiled slightly and took it, which Luke noticed.

"Are you for real?! I've just caught you cheating on me, and you fucking my girlfriend, yet you're sat here, holding fucking hands!" he yelled, making me flinch slightly.

"Okay, mate, I get that you're angry but you need to calm down." Michael spoke as he stood up.

"Fuck you." Luke spat before punching him in the face and making him fall to the floor.

"Luke, Jesus!" I hissed as I helped Michael up.

"He got what he deserved, and so will you." He spat.

"What?" I asked.

"We're done. I want all of your stuff out tonight." He shook his head. I bit my lip and nodded, trying to hold back tears.

"I'm sorry, Luke." I choked.

"I don't give a shit, Y/N. Get out, both of you." He mumbled. Michael and I looked at each other before opening the door and leaving the apartment.
