“How old are you, sis, wearing Hello Kitty knickers?” I chuckled as I stood in the doorway of Kelly’s room, taking in the sight of my younger sister in her childish sleepwear. “Ain’t you supposed to be 18?”
“You little perve, fuck off,” she said as she adjusted her nightie, but it was too short. I could still see them. Her small, perky breasts were barely covered, and I couldn’t help but feel a twinge of arousal.
“Come on, Kelly, I’m just messing with you,” I said, walking over to her bed and sitting down. “You know I’m just teasing you.”
“Well, stop it,” she said, crossing her arms over her chest. “It’s not funny.”
“Oh, come on, sis, lighten up,” I said, leaning back on her bed. “You’re always so serious.”
“And you’re always so pervy,” she said, rolling her eyes. “You need to get a life.”
“Hey, I have a life,” I said, defending myself. “I just like to have a little fun.”
“Well, stop having fun at my expense,” she said, getting up from her bed. “I’m going to bed.”
“Fine, fine,” I said, getting up from her bed. “I’ll leave you alone.”
But as I walked out of her room, I couldn’t help but feel a little disappointed. I always thought Kelly and I could be closer, but she always pushed me away.
I went to my room and changed into my boxers, then I heard a noise coming from Kelly’s room. I walked over to her door and listened.
“What are you doing?” I said, opening the door.
Kelly was standing in front of her mirror, patting her chest.
“I’m just getting ready for bed,” she said, facing me.
“Oh, I see,” I said, walking over to her. “You look nice.”
“Thanks,” she said, blushing. “I didn’t know you were still up.”
“Yeah, I couldn’t sleep,” I said, sitting on her bed. “Want to talk?”
“About what?” she said, sitting down next to me.
“I don’t know anything,” I said, shrugging. “Just want to spend some time with you.”
“Okay,” she said, smiling. “What do you want to talk about?”
“I don’t know, just stuff,” I said, looking at her. “Like how you’re always so serious and I’m always so pervy.”
“Hey, I’m not always serious,” she laughed. “And you’re not always pervy.”
“Oh, come on, sis, you know it’s true,” I said, grinning. “You’re just too innocent to see it.”
“Well, maybe you’re just too pervy to see anything else,” she said, playfully pushing me.
“Hey, I’m not that pervy,” I laughed. “I just like to have a little fun.”
I saw her eyes widen as she looked at my bulge through my boxers and saw the outline of my thick huge shaft.
“Oh, um, I didn’t know you were, um, like that,” she stuttered, her eyes locked onto my crotch.
“Like what?” I said, smirking.
“You know, like that,” she said, pointing at my bulge. “You’re, um, you’re fucking really big. OMG.” She said and turned away with embarrassment.
I couldn’t help but feel a sense of satisfaction as I saw Kelly’s reaction. I had always known I was bigger than most guys, but I had never really flaunted it. But now, seeing the look of shock and arousal on my sister’s face, I couldn’t help but feel a little proud.
“Yeah, I guess I am,” I said, smirking. “But it’s not a big deal.”
“It’s a huge deal,” she said, returning to me. “I’ve never seen anything that fucking big before. Even Simon, my boyfriend… I will shut up.”
I laughed, “Well, that’s good to know, sis. Simon’s not packing anything impressive, huh?”
Kelly’s face turned bright red, “I-I didn’t mean it like that, Jason!”
“It’s okay, sis, I know what you meant,” I said, smirking. “But I’m not just big; I know how to use it.”
Kelly looked at me wide-eyed, “W-what do you mean?”
“I mean, I know how to satisfy a woman,” I said, moving closer. “And I bet I could satisfy you, too.”
Kelly looked at me with shock and fear, but her eyes hinted at curiosity.
“J-Jason, I can’t,” she stuttered. “We’re siblings, we can’t do that. Also, I have a boyfriend, you know that. Besides, I don’t think it would fit inside me. God, I can’t believe we are even talking about this.”
“Come on, Kelly, don’t be like that,” I said, moving closer. “I know you’re curious. And I promise, it’ll feel good. I’ll be gentle; I won’t hurt you.”
“But, we’re siblings,” she said, her voice shaking. “It’s wrong, it’s incest.”
“It’s just sex, Kelly,” I said, taking her hand. “It doesn’t have to mean anything. And I promise, it’ll be the best sex you’ve ever had.”
Kelly looked at me for a moment, her eyes filled with uncertainty. But then, she nodded.
“Okay,” she said, her voice barely above a whisper. She looked at my crotch and bit her lip, “But just this once, can’t believe we are going to do this. Don’t fucking tell Simon you got it.”
I couldn’t believe it. My little sister, Kelly, was going to let me fuck her. I couldn’t wait to feel her tight pussy wrapped around my huge cock.
I pulled down my boxers, revealing my thick, throbbing shaft. Kelly’s eyes widened as she saw it, and she gasped softly.
“You’re so big,” she said, her voice trembling.
“Don’t worry, sis, I’ll be gentle,” I said, taking her hand and guiding it to my cock. She wrapped her fingers around it, and I could feel her trembling. She gave it a few strokes as precum lubed the thick end of my cock.
I guided Kelly’s hand up and down my shaft, watching as she became more comfortable with it. I could see the lust in her eyes as she stroked me, and I knew she was ready.
“Get on your knees, sis,” I said, husky. Kelly looked up at me with a mixture of fear and excitement. But she did as I said, getting on her knees before me.
I guided my cock to her lips, and she opened her mouth wide. I slowly slid my thick shaft into her mouth, and she let out a soft moan as I filled her. I started to thrust gently, and Kelly wrapped her lips around my cock, taking me deeper.
I could feel her tongue swirling around my shaft, and I let out a soft groan. It felt so fucking good to have her sucking me off.
Kelly started to suck harder, her head bobbing up and down on my cock.
I pulled my cock out of her mouth, “That’s enough, sis. I don’t want to cum in your mouth.”
Kelly looked up at me, her lips glistening with saliva. “Okay, what now?”
“Now, I’m going to fuck you,” I said, taking her hand and guiding her to her bed. “Get on your back.”
I climbed onto the bed, positioning myself between her legs. I pulled her knickers to the side, revealing her tight, shaved pussy.
Kelly did as I said, lying on her back with her legs spread. I could see her pussy, wet and ready for me.
I positioned the head of my cock at her entrance, I slowly pushed my cock inside her, and Kelly let out a loud gasp as she felt me. I was so thick, and she was so tight. I could feel every inch of her pussy as I pushed deeper inside her.
“You’re so fucking big, Jason,” Kelly said, her voice trembling. “It hurts, but it feels so good.”
I started to thrust gently, and Kelly let out a soft moan. I could feel her pussy tightening around me as I thrust, and it felt so fucking good.
“It’s okay, sis, I’ll be gentle,” I said, starting to thrust in and out of her. I could feel her pussy contracting around my cock, and it felt so fucking good.
I started to thrust harder, and Kelly wrapped her legs around me, pulling me deeper inside. I could feel her pussy gripping me, and I knew I was hitting her spot.
“Yes, Jason, it feels so fucking good,” Kelly said, her voice trembling. “Don’t stop, don’t fucking stop.”
“Ugh fuck, your cunt feels good, don’t worry, I ain’t stopping. I could fuck you for hours,” I said as I started to really go in on her pussy with my thrusts.
I lifted her nightie over top of her boobs and sucked on her nipple as my thick cock destroyed her pussy.
“Oh my god, Jason, you’re going to make me cum,” Kelly moaned, her nails digging into my back. I could feel her pussy tightening around my cock, and I knew she was close.
“Cum for me, sis,” I said, thrusting in and out of her with all my might. “Cum all over my cock.”
With one final thrust, I felt Kelly’s pussy clench around me, and she let out a loud moan as she came. I could feel her juices flowing down my shaft, and I knew I had made her cum hard.
I slowed down my thrusts, savouring the feeling of her pussy still gripping me. I looked down at Kelly, her eyes closed and her face flushed with pleasure.
“Now I would hold on tight to me as you can, as its my turn to come and am going to fuck the living shit out of your pussy.” She gripped onto me for her dear life as I started to pound her hard.
I started to thrust in and out of her with all my might, each thrust causing Kelly to moan louder and louder. I could feel her pussy gripping me, and I knew I was hitting her spot.
“Fuck, Jason, you’re so fucking big,” Kelly moaned, her nails digging into my back. “I can feel you hitting my spot.”
I could feel my balls tightening as I got closer and closer to cumming. I could feel my cock swelling inside Kelly, and I knew I was about to blow my load.
“Unngh, fuck, I’m going to cum,” I groaned, thrusting in and out of Kelly’s pussy with everything I had.
“Cum inside me, Jason,” Kelly moaned, her legs wrapped around me. “I want to feel you cum inside me.”
With one final thrust, I felt my cock explode, and I could feel my hot cum filling Kelly’s pussy. I kept thrusting, draining every last drop of cum from my balls.
I collapsed on top of Kelly, panting and sweating. Kelly wrapped her arms around me, her body trembling with pleasure.
“That was fucking amazing, Jason,” Kelly said, her voice trembling. “I’ve never felt anything like that before.”
“I told you it would be good,” I said, smiling. “You’re not disappointed, are you?”
“No, not at all,” Kelly said, smiling. “That was the best sex I’ve ever had.”
I pulled out of Kelly, and she let out a soft moan as she felt me leave her. I looked down at her pussy, and I could see my cum leaking out of her.
“I’ll get you a towel,” I said, getting up from the bed.
I came back with a towel and handed it to Kelly. She cleaned herself up, and then she looked up at me.
“Thank you, Jason,” she said, smiling. “That was amazing.”
“No problem, sis,” I said, smiling. “I’m always here to make you feel good.”
Kelly and I got dressed and went to bed, both of us feeling satisfied and content. We didn’t say anything more, but we both knew that what had happened between us was special.
And as I drifted off to sleep, I couldn’t help but feel a sense of pride. I had just fucked my little sister, and it had been the best sex of my life.
And I knew that this was just the beginning of our illicit relationship. I would ensure that Kelly and I had plenty of opportunities to explore our desires and satisfy our needs.
And I knew that no matter what anyone said, I was going to keep fucking my little sister, and I was going to enjoy every single moment of it.
