Yeah, okay, some part of me knew my little sister was growing into a total cutie, but I felt like I needed to scrub my brain every time the thought passed through. She’s my sister right? I went into her room tonight to grab a hoodie she stole.
"Nathan," she said, "fuck, learn to knock." She was lying on her back on the bed with the covers up to her waist.
“I came to get my purple hoodie back. You know, the one I told you not to take. Why? Whathya doing? Rubbing one out?” I was kidding but the sudden flustered look on Kari’s face told the truth. She was red and I smiled. It was then that I noticed both her hands were under the blanket and I heard a faint but unmistakable sound: a buzz, a vibrator. Before she could move, I jumped up onto the bed and straddled her waist and both arms with my legs. Whatya doin Kar? Huh? Whatya doing? I was in boxers and a t-shirt and could feel the vibration buzzing under my balls where I had her hands pinned to her lap.
"Okay, fuck. You caught me Nate, now get off."
"Good idea." I started to wiggle around like I was grinding on her and it made her laugh.
“Don’t be a—” She trailed off when I grabbed her waist with both hands, planning a tickle. The feeling of her tight, smooth skin through her thin halter top made me stop too. She lay still and we met eyes for an awkward moment. Kari slid her hands out slowly and put them on my thighs. Her lips parted and she licked them unconsciously. The vibrator was still on, humming away between us. I shifted forward the tiniest bit, putting pressure on her toy and her eyes went wide. “Mmm.” She bit her lip and sucked in air. I smiled and slowly, slowly ran my hands over her stomach and then moved them to her arms, aware of the layers between her vagina and my balls pressing down; the vibrator felt kinda cool there.
“That actually doesn’t feel bad,” I said.
“Is that why he’s poking out?” she asked.
“No, I think that’s your doing,” I confessed. She was stroking my thighs now, with her small, warm hands.
“Is it? You like what you see?” She bent her shoulders and arms together so that her small tits swelled up at me. The look on her face made me realize that she had thought of this moment too. Played it over in her mind like I had, fantasized in the dark about the sibling on the other side of the wall.
Her hands were moving up and down my thighs again, edging closer and closer to me. I stoked her arms to the shoulders and moved over to the sides of her breasts. Leaning forward like that must have pushed the vibrator right against her clit, because she moaned again, bit her lip and closed her eyes for a second. Now I was kneading her gorgeous little tits, nipples tracing against my palms through the fabric of her top. I started to move my hips just a fraction, up and down, and as I did, she started to dig at my boxers, pulling my dick though the flap with both hands and touching it with feathery, hesitant motions.
“You won’t break it,” I said.
She changed her grip and stroked my pulsing hard on while we held eyes and shared the pleasure and excitement building up in both of us. After a minute of watching her beautiful eyes on mine and enjoying her pumping fist, I lifted up and shifted forward over her stomach so I could rip the blanket off her legs. Like I expected, she wasn’t wearing anything, and apart from a trim little patch of blond, her pussy was bald and glistening. I picked up the shiny purple dildo and started to really set to work on her clit with it. Now that she could get at it, she fished my balls through my boxer flaps and cupped them while the other hand pumped me up and down firm and steady. We moaned and groaned in this position and I alternated between sliding her little toy over her clit and inside her. To do this I was twisted around and looking behind me so it came as a shock when she put me in her warm, wet mouth.
“Ahh, fuck Kari, that feels good.” She was roaming her tongue around my cock-head and slurping at it while I pumped the vibrator in and out of her amazing little pussy. She broke off for a moment to work the spit on my head down the shaft and over my balls, using both hands like a pro, my gorgeous little nubile sister. At some point she had been handling her own tits because her top was up at her neck now and I could see her excited little nipples, perfectly placed and rosy pink. I leaned over her and pinched one and then kissed her grinning lips. “Want to 69?” I asked.
“Yeah! I mean, that’s like… How would that work? Do I go on top or do you?”
“Ether is fine,” but it would probably be easier for you to give me head if you’re on top.”
“Okay.” She sat up and I lay on my back and starred in awe as my cute little sister backed her perfect tight little ass toward my waiting face. She lifted a leg over my body and eased her drenched pussy against my mouth. “MMmmph. Ohhh! Oh God Nathan that is…” Instead of finishing her sentence she put her mouth around my cock and started to suck away, loudly slurping, and grinding herself against my tongue and face at the same time. We were bucking and moaning together and it was the freest sexual moment of my life. I took up the vibrator again and put it inside her while I flicked her clit with my tongue, building speed. She started to squeal and moan so that I knew she was getting close. “Oh fuck, oh fuuuck. Uh uha uhhhhh. Mmph, mmph.” I picked up the pace with the vibrator and made sure that the angle was getting her G-spot. The more turned on she got, the move vigorously she sucked my dick. Her angle must have been better or she was getting more comfortable with her brother’s cock because she was going deep as hell, and sucking so hard I thought the sheets would go up my ass.
Her first orgasm happened as I was getting close. She let me pop out of her mouth and started to slap my thighs and whine in what was the sweetest little whimper I had ever heard. It was a strange and astounding thing to hear my little sister out of control with pleasure like that, grinding away on my face. I could see her convulsions twitching the bottom of the vibrator that was in her. I slowed after she peaked and pulled the vibrator out. She was gasping but still had a hand on my cock. After a few seconds she had me back in her mouth and I started to squeeze her butt cheeks. I worked her clit again, gentle and steady, careful to not over-stimulate. Soon enough she was moaning again, her second orgasm coming on fast. I stopped what I was doing and flipped her on her back hovering over her. She had a devastated look on her face, until she realized what I was doing. I dipped into her tight pussy at an angle, with my hips above hers so that every down-stroke when right across her clit. When I knew I had the right spot and pace I grabbed her arms at the wrists, pinned them above her head and pumped away, both of us moaning and sweaty and out of control now. Like that, we crashed against each other and she instinctively moved her hips so they met my thrusts. We came together for what seemed like forever and her pussy clamped down, milking the life from my cock one beautiful pulse at a time.
When we’d caught our breath, I looked at her started to laugh.
“What is it?” She asked.
“Ah, it’s nothing,” I said. “I was just thinking you can keep the hoodie.”
