"Justin, come downstairs! They're here!" Mom yelled from downstairs.
I raced down the stairs, facing one new face as I reached the bottom. I already knew my mom was dating this guy but I didn't know he had a daughter. Damn, she is hot though. Too bad she's my soon-to-be sister.
"Justin, this is (y/n). (y/n), this is Justin." Her dad introduced us.
"Alright cool." I said, turning around. I wasn't interested if she's going to be my sister.
"Justin, why don't you show her around?" Mom suggested.
I inwardly groaned and grabbed (y/n)'s hand. Her hand was soft like soft churned ice cream. You see where I'm coming from? I walked up the stairs, being slowed down a little by (y/n)'s slow walking. First, I pulled her into the guest room, which was the closest. There was nothing interesting in there so we went over that quickly. Next mom's room. Big, but not much I could tell her about. Once we went into my room, I let go of her hand.
"This is my room. The best room of the house."
"It's a typical boy's room." She said.
"Still the best." Really, Justin? That's all you could think of? Wait, why do I care she's only my sister.
I watched as she grabbed a controller from the floor and started playing Call of Duty. I watched as she went up to round 7. I could totally beat that though.
"You're aight, but watch the master." I said, before grabbing a controller.
Soon enough we were sitting on my bed having the random conversations. It could go from talking about life to talking about who can say the alphabet faster. That's why we got along so well. We didn't care about anything else in the world right now. Or atleast that's how I felt.
"Are you even paying attention?" (y/n) said, before grabbing a pillow and hitting me with it.
I grabbed a pillow and hit her back. She hit me a couple more times before I pinned her to the bed. "I can tell you one thing. I'm the best in bed." I said, smirking right after.
"You probably suck."
"You probably swallow."
She widened her eyes before smirking. "Probably."
"Actually, no. I'll prove you wrong." She said.
I was confused at where she was coming from. I felt her wiggle from under me and she got up, sitting in front of me. We made eye contact and she went in for it. She kissed me. It felt so wrong but so right. Cliché, I know. Her lips felt so good on mine that I couldn't resist. I let her continue.

The tip of his dick hit the back of my throat and I gagged a bit. He was just too big. I went up, my mouth only on his tip as I pumped the rest of his shaft. I let go with a small popping sound. I moved down to his balls and I sucked on them, giving each attention while pumping him quickly. I made a stripe up his member all the way to the tip. I accidentally made a soft scrape against his tip with my teeth which caused him to curse under his breath.
My head bobbed up and down on his dick and I made eye contact a couple of times. He bit his lip and I knew he was trying not to give me satisfaction. I sat up and let go of him.
"No! F-fuck, (y/n), please," He moaned softly.
I smirked before hollowing my mouth and sliding him into my mouth again. I sucked harder and pumped faster. Without a warning, I felt him shoot his cum into my mouth. I wasn't going to lose my word to Justin. I got up and walked to the bathroom. I spit out the cum into the sink and poured water in a cup. I rinsed out all of the cum I tasted and walked back over to his bed.
"Okay, you were right," he let out a heavy breath, "fuck that was so good."
I kissed him passionately before laying next to him. He turned sideways and his arms wrapped around me. I felt his dick touch my stomach and I wanted him to touch me, no matter how bad it sounded.
I grabbed Justin's dick and he just kept his eyes closed. I moved up and right back down so that he could easily slide into me. His eyes shot open and he let out a throaty groan. His hands made their way to my waist and he held on. He gripped onto me and started thrusting himself. I never wanted this so badly. Might as well let him continue.

She was inside of me and that made me feel fucking great. I gave her sloppy kisses on her neck while still thrusting into her. I moved our position while still thrusting. I couldn't stop. She's like a drug.
I thrusted faster as she hovered over me. She stopped me all of a sudden and let out a breath. I didn't want to stop. It was torture.
She rocked forward and started moving up and down herself. I leaned my head back and closed my eyes, enjoying the pleasure while it lasted. Her soft moans only made everything better. I was coming closer and closer to the edge.
"J-Justin! I'm so c-close..." She whimpered.
"Shit, m-me too. On 3, babe." I said, opening my eyes.
We counted together and came once at the same time. It was crazy how we did that.
She got off me and collapsed onto my bed. I took all the strength I had to get up and lock the door, just in case somebody came in. As a matter of fact, we had sex with the door unlocked and yet they still didn't check on us. I'm sure my dick made her pretty loud.
"How was that?" I asked once I got in bed beside her.
"Magical." She replied, closing her eyes.
"Couldn't agree more."
