My sister's boyfriend

Prologue

It was a hot summer day at the Payne house. Liam was in the backyard, swimming in their recently installed pool as Zayn and Perrie were sitting on the sun chairs surrounding the water. The dry heat was balanced out by the water spread onto their skin. Perrie laid her body across from Zayn comfortably, texting away on her phone.

Liam was in his own world, going laps around the pool. Liam looked up briefly, only to see Zayn was watching with a glint Liam couldn't quite understand. Confusion was evident on Liam's face and Liam was going to look away from Zayns piercing stare, but it seems his sister did it for him.

"Liam, you want to go get us some drinks?" Perrie smiled at her younger brother. Zayn broke the stare to look at his girlfriend. Liam nodded once, before getting out of the pool.

The water weighed down his shorts, showing a perfectly fit chest and a very defined V line. Zayn licked his lips at the sight of it, refraining himself from biting his lip. Perrie didn't notice, rambling on about an outfit she saw at the mall. Zayn didn't take his eyes off of the man before his being was out of sight. A feeling sparked in Zayn, an intuition to follow Liam. Usually he refrained from it, but he was feeling spontaneous today.

"Babe, I got to use the bathroom" Zayn removed the legs that were weighing his body down as he walked inside of the house. Perrie called out after him but he continued walking, knowing she would be fine by the time he got back.

He wasn't lying; he did have to use the bathroom. It's just that Zayn wasn't completely telling the truth. The bathroom wasn't the only thing he was planning to do inside the house. He had a more precise idea, one that included a risk that he wasn't quite sure if he wanted to take.

Zayn did his business and left the bathroom, taking a route through the kitchen to get back outside. He wasn't planning on going out just yet. Liam was making lemonade on the counter, a towel wrapped around his waist and water dripping from his hair.

Zayn hid behind a wall in the hallway, watching and refusing to get turned on by such sight. It was something that's really hard for Zayn to do. It failed nonetheless as the attraction and the excitement was too much to actually control. Zayn considered if he really wanted to try, to risk what he was going for him to get what he wants. His confidence dropped as he thought about the rejection that he knew was going to happen. Scenarios played into his head but he shook away all of them.

He breathed before regaining his posture, along with his confidence. A smirk found its way onto Zayns face and he walked from the wall to the other side of the counter. Liam barely turned his head, not enough to see that it was Zayn beside of him and not someone else. 

"It's not done-" Liam felt the presence of someone, assuming it was his nagging sister. Liam hated that she had only become that way since high school. She became popular and got that hot boyfriend that everyone wants. 

Zayn never talked to Liam much. He was usually too focused on Perrie to see he existed. They know stuff about each other. Perrie can't hush up about Zayn to save her life, talking about every little detail, even how he is in bed. Liam's face would wrinkle as he tries to delete the image Perrie under the man from his brain. 

Liam looked up finally when there wasn't an answer, seeing that it was Zayn. He felt tense all of a sudden, but he tried to ignore it as he poured sugar into the container. 

"Hi." Liam was blunt with it, hoping it would make him go away faster. 

"Hey," Zayn said slowly, still drinking the appearance of Liam Payne. Oh, did Zayn like the sight.

"You can go tell Perrie it's almost done." Liam didn't look up again, but listened to hear Zayn leave. All he heard was silence. Liam became frustrated at this. He's supposed to be gone already, he usually always is. That's the way this goes: Zayn speaks to him twice then goes to Perrie to stick his tongue down her throat.

"I said you can go tell-" Liam was cut off, forced against the counter, his back to it. Liam gasped as Zayn felt him.  Hands roamed over his stomach and pecks; The muscles of his chest flexed as his fingers ran against it.

"Tell her what?" Zayn asked, his voice husky and deeper than usual. Liam inhaled Zayns breaths, for Zayn was too close to him.

"What are you doing?" Liam snapped at him, but Zayn didn't say anything. He just walked closer, making no space between the two of them.

Liam didn't react fast enough. Zayn was already at his neck, nipping at the sensitive area. Liam kept his mouth shut, his body tense. Maybe then, Zayn would get the message. The plain failed as another gasp left his mouth when Zayn nibbled at a certain area. Liam's fists were clenched at his sides. He wouldn't let Zayn get to him.

"Harder if you try to fight me" Liam heard suddenly, then realized Zayn said it.

"I don't want you" Liam said angrily. Liam doesn't know if he was mad because of the suddenness of it or the fact that this is his sister's boyfriend. He prays that it is more of the second option.

"Other things say so" Liam looked down briefly. There was a small tent through the towel. Liam cursed himself silently, much to the attention to Zayn, who only smirked.

"I hate you" Liam glared and Zayn backed away, shocked at the words. He was definitely not expecting that reaction. 

"What are you two doing?" Perrie wondered, walking inside towards her boyfriend.

"Oh nothing, just having a little chat" Zayn easily lied to his girlfriend, sending her into a hug. Zayn didn't close his eyes, Liam observed. He was looking at the floor before looking up to him. Zayn winked at Liam, and Liam scoffed silently before leaving the kitchen.

"I'm going over to Harry's, I'll be back soon" Liam stated over his shoulder, going into his room. He showered and changed into his new clothes. It didn't take a genius to hear the giggles down the hall and know that they was about to have sex again. 

Liam groaned in mild anger over what had just happened. He just got a semi from his sister's boyfriend, who is now about to have sex with her.

Liam locked the door on his way out, trying to tune out the noises he heard as he left. His face shriveled in disgust. As he strolled down the street to Harry, his best friend, he pondered over the situation some more.  It doesn't make sense and Liam didn't try to make sense of it anymore with a shake of his head. 

He's going to pretend it never happened.
