Big Brother | Kyungsoo

Urges (smut warning!!!!)

-Warning! Smut ahead! I'll dedicate this chapter to it, so if you want to skip it, go on to the next one.-

When we were home, he brought me to my room, and came in, himself. He sat on my bed with me.
"Y/n.. what did I do wrong? Did I hurt you?" he asked me.
I immediately answered, "Of course not! No no no.. you haven't done anything wrong.."
Softly, he asked, "Why are you avoiding me..?"
Even softer, I answered, "I am disgusting.."
He grabbed my hand and looked me in the eyes. Hurt, he said, "Never say that, y/n. You are not disgusting. Not in the slightest. You are wonde-"
"No, you don't get it!" I interrupted, pulling my hand away.
He went silent.
"Lately, I've been feeling so weird about you.." I told him.
"Weird..?" He asked. I nodded.
"Having urges.. to treat you in an odd way.. a way you don't treat siblings.." I said, embarrassed. He looked at me with a shocked face.
"You mean... Sexual.. urges..?" he whispered out. Once again, I nodded, but ever so slightly. His lips formed an 'o' shape, and then a light smile.
"Give me an example..?" He asked.
I nodded, and whispered, "Like, when you hugged me after your shower.. I so badly wanted to kiss your neck.. and chest..."
"Would you like it if I did that to you..?" He whispered back. I nodded. He started leaning closer to me.
"And if I... sucked on your neck..?" He asked with a raspy voice. I nodded again, feeling my heart rate quicken. He leaned even closer.
"And my tongue.. would you like it.. deep in your mouth..?" he inquired, looking at me with an odd glint in his eyes. I nodded, and before I knew it, he was on top of me.
He leaned down to my ear and whispered, "Are you sure about this?"
I breathed out, "Yes.."
Slowly, his plump lips landed on mine. I kissed back, still hesitant, and the kiss deepened even more. I felt his tongue working to enter my mouth. Without warning, I felt one of his hands pulling my shirt down. I gasped, and his tongue happily entered. I could taste his every fiber, and there were no breaks to take a breath. I found my tongue inside his mouth, exploring an area I never had. He broke the kiss, leaving me panting, and started trailing kisses down my neck. He hit a sensitive spot, causing me to moan, and sucked there to keep me going. It felt so odd, not only because he was my brother, but because I had never done anything like that with anyone. He continued going lower down my neck, until he was sucking on my upper chest. Once again, he stopped, asking me, "Are you really sure about this?" I looked down at him, eyes full of lust, and he didn't need an answer to keep going.
He continued lower and lower, until he couldn't pull my shirt down any further. He looked at me for approval, and I granted him permission. He pulled off his own shirt, and then, carefully, pulled off my shirt. He stopped and stared, looking me up and down, eyeing my lacy bra as he licked his lips.
"Y/n... Wow.. who knew my little sister had such nice.. ah.." he complimented, in a husky voice. I blushed dark red, and suddenly felt so self conscious. I put my hands over my chest, and looked away in embarrassment. Gently, he removed my hands, and started leaving kisses all over my chest. I felt his tongue licking inside of my bra, and wondered if I should remove my bra. My thoughts were confirmed when he growled out, "take this off."
Seeing a whole new side of him, I complied, and he helped me undo the straps. Once again, he stared in awe, now at my bare chest, and I attempted to keep him from looking by kissing him. As we kissed, he spoke, "if this is your way of telling me to hurry, I'll do just that."
He moved his lips down to my left nipple, and started sucking on it, while twirling his tongue. Suddenly, I felt something I never had before. My lower region felt.. wet?
Noticing the way I was squirming and moving my legs, he smirked.
"Don't get too impatient, princess. We'll get there~" he teased. Without thinking, I grinded against his leg that was between my legs. Surprised, he stared down at me. He bit his lip, saying, "How am I supposed to control myself when you do things like that.. you're always doing this to me, y/n.."
Impatiently, he took my pants off. Seeing my damp underwear, he smirked at me.
"What's the meaning of this, princess? Excited?" He said in a cocky tone.
Before I could reply, I felt his fingers rubbing me through my panties. I let out a noise I had never made before, and he seemed very satisfied. I started getting impatient, squirming again, and he put his hand inside my panties. He was quick to put a finger inside of me, because I was far past damp enough to let it slide in with ease, and once again, I let out a moan. He started moving his finger quicker, and then, he inserted another. It was never ending. Every added finger was a new experience, and I felt my stomach tighten. Suddenly, he removed his finger. Frustrated as hell, I glared at him, and let out a whine. He smirked.
"Soon.. not yet.. first, it's my turn." He stated. I was confused, but got the drift when he took off his belt, and tucked his ripped jeans down, to reveal his boxers. Pulling them down, as well, he took them both off. Before I knew it, his large, erect member was in my face. I felt overwhelmed as he instructed me to open my mouth. He gave short instructions, but assured me he'd do most the work. I teased him a bit, doing my best, and then he had enough.
"Take a deep breath, y/n. I won't hold back. After all, you made me deal with this alone when you turned me on during that movie." He said, looking down with a half smile.
Before I could think over what he said, his member was inside of my mouth. It took up all the room my mouth contained, plus some, and soon I felt his tip hitting the back of my throat. He held my head in his hands, as he pushed it back and forth, on and off of his huge member. He let out a deep moan, and started thrusting faster. I tried to speak as it roughly hit my throat, but he thrusted even deeper, and let out noises similar to hyperventilating.
"Ah, ah, ah... y/n... Fuck, y/n, this is so good.... Oh my fucking God... Yes.. it's coming! Ah, it's-"
I felt a warm liquid fill my entire mouth, and he removed his member. The liquid spilled down my throat, and out of my mouth, running onto my chest. Panting heavily, he brought his face to mine, and started kissing me. He licked the inside of my mouth thoroughly, and licked the juice that had spilled down my chest.
"Jesus.. you're so fucking hot when you look at me like that, y/n. Do you want me?" He asked.
"Yes, Soo... I want you.. I want you so bad.." I whined.
"Where do you want me, princess?" He whispered into my ear.
"I.. inside me, brother.. please.. I need you here.." I said, motioning to my lower region. He chuckled, "Y/n, we're siblings.. isn't this weird?"

At that moment, I could care less. I wanted him inside of me, right then.
He lined his member up with my spot, and whispered, "Mother and father will be pretty angry if they know we did this." I bit my lip in anticipation, and that seemed to be his last straw, seeing as he went deep inside of me. It felt so tight, and hurt some. My eyes watered, and he dried them with his finger.
"It will feel better soon.. pinkie promise." He told me.
He began thrusting in and out of me, softly at first, then a bit harder, then so hard. And I wanted him to.
"Kyungsoo... It feels so good.. I've never felt this before.. god, go harder!" I moaned out. He smirked, lifting on of my legs over his shoulder, and everything got so much more intense. He watched my chest as it bounced with every movement, and I watched his fit arms and they clenched in excitement.
Faster, and faster, and faster, and soon, I felt my stomach clenching again. I knew he wouldn't leave me hanging this time. He felt too good to. I could tell from the way he was pulling my hair, and letting out deep, raspy moans with every move.
I saw a white light, as pure pleasure passed over me. I moaned, "Kyungsoo!" as I came. He came short after, and moaned the same way a beast growls. Panting, sweaty, and out of breath, I laid back on my bed. He removed himself, and laid beside me. Body to body, we held eachother.
"I love you, y/n." He whispered. Before I could reply, he added, "in the least platonic way."
"I love you too... I want you to be mine, Kyungsoo." I confessed. He smiled, and brought his lips to mine. We kissed passionately, until I started feeling sleepy, and pulled away. He understood, and brought my head to his bare chest. Like that, we fell asleep.
