Liam: They'd always said that they all had different types when it came to girls. Obviously you were the exception to that because although you were dating Liam, Niall was constantly flirting with you. In the beginning Liam had been reassuring you that that was just how Niall was with girls; more and more recently though you'd caught him glaring at the blonde when he was talking to you. One day, you two were left alone and he was already extremely giddy, so when he pushed himself over you, it was no big deal, but suddenly his lips came crashing down onto yours, his hands burying themselves in your hair, and you weren't exactly sure what to do, so you kissed him back.
Niall: When Louis got drunk, all of his inhibitions flew out the window. He would do anything anyone suggested and he would kiss anyone, no matter who it was. That was of course a problem when you were with him, Niall, and the other boys at an after party where there was quite a bit of drinking going on. Louis had been drinking the most since he was actually the only legal one and when he ran into you, he stared slurring his apologies and he went in to kiss your cheek but drastically missing and hitting your lips. Now he didn't pull away, he did the opposite by delving in deeper and taking a brief taste of the inside of your mouth before he was pulled away from you by an angryish Niall, for once not laughing at Louis' actions.
Louis: He'd been your best friend in the band ever since you started dating Louis. Since the two of them were so close, you'd formed a bond with him and Zayn was the one that you could go to to talk about any problems that you were having with Louis. Frequently, he would get home just to find you and Zayn sitting in front of the TV, talking and smoking. But recently things had changed and he wasn't coming over or as willing to talk about your current relationship. You lured him over with false promises and when he arrived just to be disappointed, you locked the door. "Please, talk to me. Why've you stopped hanging out with me, hmm? Is it something I said or did?" He shook his head, scratching the stubble covering his jaw. "Then what, Zayn? I don't want to lose you as my best friend." "I want to be more than your best friend, Y/N. I don't want to hear about your boyfriend, I want to be your boyfriend." And then he leaned forward, slanting his lips softly over yours. His kiss was soft but his stubble scratched your face. Hours later, when Louis finally arrived home, you kept the kiss a secret, the only evidence of it happening was the slight scratches left on your face.
Zayn: "It was an accident! I swear, Zayn! You know I wouldn't ever purposely do anything like that!" Harry was backing away from Zayn whose temper was flaring up after catching Harry kissing you. The unshocking truth was that it wasn't actually accidental; it had been going on for weeks now. "Zayn, stop!" you grabbed his arm and jerked him around to face you. "You can't get mad at him for kissing me when I know for a fact that you've cheated on me at least twice since we became serious." He frowned, and Harry now forgotten waved goodbye and vanished from the room to leave you and Zayn alone to discuss what would happen in your relationship.
Harry: From day one he'd been head over heels for you, invested 200% in the relationship and he would do anything for you. You loved him to, but not nearly as much as he loved you. Liam was a great guy to you soon came to realize. Where Harry was gentle and soft, Liam could be intense and rough. You didn't act on the feeling you were having towards him for a long time until you realized that the spark that had once been strong enough to bond you and Harry together had faded away. You felt like crap for doing it, but it just sort of happened when you ran into Liam on the bus one night as you stumbled towards the bathroom. He steadied you and then lips were colliding, fingers tracing skin, and clothes removed and you were hidden in his bunk, trying to be quiet. Afterwards, you slipped back into Harry's bunk, his arms wrapping around you, nose nuzzling into your neck. The next morning the other boys thought that Liam had just smuggled a groupie onto the bus and you weren't about to tell them any different.
