Having been away from home for a while, it was certainly nice to sleep in our own bed again. I always sleep better in my own bed, and always look forward to getting back to it when I'm away. Sarah and I slept soundly that first night back. I was the first to wake, and noticed that my sister's body was bathed in the morning sun, pouring brightly through our bedroom window. I propped myself up on my elbow, and watched her sleep peacefully. I combed my fingers through her hair, gently pulling it back from her face so I could see it completely. I continued to stroke her hair for a bit while watching her. I eased the covers back slightly, about down to her waist, and took in her supple breasts. They stacked tougher perfectly as she lay on her side. I couldn't help myself, and gently grazed my fingers down her temple, across her cheek, then down her arm, and across her breasts. I saw her nipples start to harden at my touch, and I used my thumb to wiggle one like a tiny little joystick.
Wanting to see more of my sister's beautiful naked body lying beside me, I carefully pulled the covers farther back to expose her down to her smooth little pussy. Sarah instinctively but unconsciously snuggled closer to me to regain the heat lost by my exposing her body. Her firm tits with their erect nipples now pressed into my chest, and her legs pressed against mine. I felt my cock start to swell at the new contact, and my flow of precum started to spill out of me, and onto her legs. As my dick grew harder and harder, it worked itself between her legs, just making contact with her puffy, swollen pussy lips. I could feel her heat radiating onto me, and pumped more of my fluids against her twat. It spilled out, and began to soak her legs, and thoroughly lubricate my cock wedged between them. I lay back down, my sister's sleeping face just inches from mine now. Our bodies close enough that I could press forward slightly, and slide the head of my penis between her tight pussy entrance. I pressed into her, and rested the tip of dick just against her clit. I squirted so much precum into her snatch that I couldn't tell if it was her moisture or mine, or perhaps a combination of the two. Her body was telling me that she was ready to fuck, but I did not want to wake this sleeping beauty before me.
After a short time of us lying face to face with my arm around her back to keep her exposed but warm, Sarah's eyes started to flutter open. As soon as she was coherent enough to recognize she was in bed with me, a sweet smile spread across her perfect face. Her deep green eyes stared into mine, and she mouthed, "good morning," to me. I had only to slightly move to kiss her lips. My hand went to her face, and I touched her cheek, then again, lightly brushed her flowing dark auburn hair back. With my hand behind her head, I pulled it to me to kiss her again. Her arm went behind my back, and pulled me tighter to her, causing my dick to press up inside of her pussy farther. I was inside of her just a couple of inches, just remaining still, and injecting her hot twat with more natural lubricating fluids. Our kiss began to become more hungry, more eager. As we lie together in bed, our arousal grew at the same time, and we worked our way into a horny frenzy together. Sarah started slowly humping her body against mine, trying to get me deeper into her, wanting me, needing me.
As we kissed, our bodies slowly turned to me lying on my back, pulling her with me. Her leg slid over me, and we rolled together, her ending up lying atop me, her perfect breasts pressing into my chest. I felt her hard nipples digging into me, eager to be sucked on and played with. Once I was fully on my back, Sarah opened her legs, and her pussy slowly devoured the length of my penis inside of her. She worked her hips up and down on me, letting her flowing pussy make love to the stiff rod within her. She breathed slowly and deeply into my mouth, as our lips just barely touched as she started to impale herself on my rock-hard dick slightly faster. As she rode me, my sister raised herself up, letting me take in the full view of her amazing breasts as they hung from her perfect body, their nipples pointing directly at me. I reached for them, and Sarah knowingly lowered them to my awaiting and eager mouth. She lowered an extended nipple to my mouth, and I gently sucked it. With the nipple between my lips, I bit down ever so slightly, and flicked my tongue over the stiff nub. Releasing it from my teeth, I sucked it. I sucked that nipple like a nursing baby, as though I was trying to get her milk to flow. I closed my eyes, and listened to Sarah's breathing intensify and become more rapid as she rode me, and I sucked her tits. When I let go, I looked up at Sarah, who had a look of pure lust and desire on her face. She lowered her other breast to my mouth, and I gave it the same attention as I had the other, this time looking up and meeting her eyes. Her eyes were filled with desire as she watched me suck on her sweet tits.
"J, I want you to cum inside me before we go talk to mom and dad. I want to be full of your cum while we're talking to them."
I didn't say anything, but kept sucking that ripe tit. My hand squeezed the other, pressing the two together as I sucked them, and made love to them. With my other hand, I ran my hand down her body to her plump ass. I pulled gently, and started to thrust up into her. Sarah's legs came up now, and she knelt over me, allowing her body to take me deeper inside of her hungry pussy. Her tits now out of reach for my lips, I worked them with my hands. I squeezed the perfect cones, and let them slip from my grip so that the last thing to touch my fingers were her nipples. Sarah watched as I played with her breasts, and looked past that to watch her brother's dick repeatedly disappear inside of her, then reappear, the repeat. She rose up to where I was just barely inside of her, then slide back down, taking me in fully. I started to meet her motions, and pushed myself deeper inside of her every time she lowered herself.
"Deeper, J," she breathed.
With that, she got herself up onto her feet, so that she was squatting over me, her feet flat on the bed beside me. In this position, her beautiful vagina was in the best position to get my penis the deepest possible distance inside of her. As she made love to me rod, I could feel it knocking at her cervix, wanting to keep going deeper. That's physically impossible, but it sure did stimulate Sarah even more. She kept bouncing harder on me, letting me contact her inner depths. Sarah started to shake. Her whole body shivered like she was cold, then harder. Her tits jiggled as she shook. Knowing what was coming, I held my hands up to support her. My sister held onto my hands, and with one final downward thrust, my dick hit her cervix, and her pussy exploded. Her heavenly nectar erupted around my dick, and flowed onto my abdomen and balls. Sarah remained on me, my cock still pressing against her cervix, and screamed out as she came on me. The erotic vibrations her body went through sent me over the edge, and I painted her insides with life giving sperm. What felt like buckets of cum raced up my shaft, and rocketed into the voids of my sisters vagina as deeply as they could possibly go.
Her womb filled with my incestuous seed, Sarah's body started to calm down. She slowly lay back down on top of me, her body periodically slammed with orgasmic aftershock. With each one, her whole body twitched hard.
"Oh my god, J," Sarah said, as he lips were close to my ear. "I don't think I've ever cum so hard."
I didn't say anything. I just put my arms around her, and hugged her tightly as she let her legs again extend in parallel to mine. My cock remained firm inside the steamy grip of my sister's pussy.
"You came so deep in me, too!" Sarah said excitedly, lifting herself up to look in my eyes.
As she smiled down at me, I flipped her onto her back, my dick still hard inside of her. Together, we scooted to the edge of the bed. Her legs dropped over the side, and I now stood over her. Leaning down to suck on her breasts again, I started pumping myself into her once more.
"Again," she questioned through ragged breath.
I released the tit that was in my mouth, and said, "you said you wanted my cum in you before we go to mom and dads."
"I'm not complaining, but I think I'm full!"
"There's more. I'm still hard, so why waste it?"
I pulled my sisters legs up over my shoulders, and commenced fucking her sloppy slit. When I came in her before, we were making love. Now, we were fucking. My sore and spent dick slammed into her pussy repeatedly. I grabbed her hips, and thrust myself into her as hard as I could. Our fluids were combining, and running down her ass cheeks, and coating my balls. I could feel more and more precum being forced into my sisters steamy snatch with every thrust, along with remnants of semen from my previous ejaculation. I felt Sarah's twat tighten around me, and saw her breathing stop. Her hands squeezed her breasts together as another orgasm overtook her delicate body. Again, she shook violently. I pulled my dick out far enough for her to have room for her body to comfortably ride the wave, and I watched as her fluids again sprayed from with her. With my penis still slightly inside of her, her juices were deflected from it, and sprayed up onto her torso and breasts. The splash was so intense it even got her face wet.
When she finally finished squirting, and her body had relaxed, she said, "oh my god, J, I'm so sorry."
"No need to apologize, my love. That was incredibly sexy," I replied as I started pounding her again. "I'm going to cum in you again."
"Do it J, fill me more with your cum. Cum in my pussy!"
And with that, I did. There wasn't much this time, but it was enough to top her off, and I had enough force behind it that it was forced from within her. There simply wasn't room enough in her tight little cavity for both my dick and it's life-giving liquids. I pulled out, and let Sarah's legs down.
"Let me taste you," she demanded. "Let me taste us."
