Lupe POV

Have you ever met someone that you can't have but want them so bad that you'll do anything for them? For me, that person would be Avery, he's my sister's boyfriend. They've been together for a couple of months now. If I'm going to be honest, I don't feel bad for having feelings for him, cause my sister treats him so bad, and I've tolden her to stop, but she doesn't listen. So, I've stopped trying cause nothing is getting through her thick hollow head.

He comes to our house every day of the weekend and sometimes weekdays. He's only 2 years younger than me, he's 18, while I'm 20. Whenever he's here, I sometimes flirt with him or tease him to see him all flustered. It's currently the weekend, and he's over right now. My parents are at work, and it just is three in the house.

I knocked on my sister's door.

"Come in" she yells. I opened the door and my sister was all dressed up and Avery was sitting on the bed, doing nothing.

"I'm gonna order wing stop, do you guys want some?" Avery was about to say something, but my sister interrupted him.

"No we're about to leave, I have to go meet with my friends at the mall, and he's going home, right?" She says, looking over at him with a smile, but not a kind one but one that says 'you better agree with me.' I look over at him and he lowers his head and nods.

"Why don't you go to the mall and him and I can hangout? What do you say?" I asked him, not wanting him to go home so early. He looks back up.

"Sure." Avery says, with a small smile. I can see Lola roll her eyes.

"Whatever, I'm leaving now." She says, heading out the door without saying bye to Avery or giving him a kiss. Sh slams the door on her way out.

"Wanna come to my room and watch a show?"

"Sure." He gets up and walks towards me. I move to the side, so he can get by. He was a lot shorter than me, I was 6'4 while he was 5'6. You would think that's short for someone who has tall genes, but I have a different dad, but the same mom as my sister. I've always had a feeling she didn't like me since I was basically a 'outcast' in my family because they were their own family since they all shared DNA, and I was just an add on.

Anyway, I ordered the wings once we got in my room. He was sitting on my bed with his back against the wall.

"I'm gonna shower before the food gets here." I grab a towel and head to the bathroom. I turn on the water and let it heat up. After I'm done, I wrap a towel around my waist, lower than I usually do.

I usually change in the bathroom, but this time I forgot my clothes outside, knowing Avery was out there. I opened the door and I saw Avery look up from his phone and just stared. He was sitting on the edge of the bed. I walk closer to him, and he doesn't make eye contact with me. As I stepped in front of him, he finally looked up. We didn't say anything as I leaned down, wanting to kiss him.

But I was interrupted by the sound of the door knocking. He jumped back. His face red and flustered.

"I- I should probably go get that." He says, quickly, before getting up and pushing pass through me. I smirked as I watched his run down the stairs. I quickly get dressed and head down stairs to the living room. I guess we're eating here now. Before I sit down, I head to the kitchen and see Avery trying to reach a cup on the top shelf.

I try my best, not laugh and make my way to him, coming up behind him. I reach upward to grab a cup, my body presses up against him. I place the cup down and bring my lips to his ear.
