Half Sisters 1

Half Sisters

I went barreling into the house in a rage, slamming the front door behind me. The whole house seemed to shake.

"Allison! Where the hell are you?" I yelled, as I went stomping down the hall and found my half sister in her bedroom.

"You bitch! You fucked my boyfriend!" I accused her. "Now he's dumped me."

Allison and I usually get along. Sis is a high school senior. I graduated last year. We have different fathers ... same mother, of course, and hence different last names. Maybe my boyfriend didn't know Allison and I are sisters, well, half sisters, because of our names. But Allison sure as hell does and I was pretty ] she knew I was going out with Roy. So she had no excuse for doing what she did. She's a year younger than me and I hate to admit it, a lot prettier with really large tits and long sexy legs. I've always been the short frumpy one.

"Who? I didn't even know you had a boyfriend," she retorted.

"Bullshit! You knew I was going out with Roy," I yelled at her.

"Oh him. Yeah, I fucked him at a party Saturday night at Melissa's. Sorry," she said, not sounding the least bit contrite.

"You bitch, how could you?" I said and stepped up to her and pushed her as hard as I could in my rage.

She stumbled backward onto her bed with a yelp. I leaped on her and started flailing my fists at her, I was so angry.

"Chill, Beth, what the fuck, I didn't do it on purpose. He came onto me and I was pretty wasted. Though he is really cute, it just happened," she said, as she held her arms up fending off my rather tepid blows. I punch like a girl.

I lay on top of my sister pinning her down, then pushed myself up on my elbows and looked her in the eyes. She looked sincere.

"You really didn't know?"

"No, honest. And, if he was your boyfriend, he shouldn't have been all over me at the party playing octopus, his hands were all over my tits," she told me.

I don't know what came over me, maybe it was the mental image of my boyfriend, or ex-boyfriend now, groping my sister's boobs.

"Like this?" I said as I placed my hands on her much larger breasts and squeezed them over and over, pinching her nipples through her tank top.

"Ouuu, Beth, that feels pretty nice," she moaned.

"Oh my god," I yelped, "I don't know what came over me."

I started to pull my hands away, but Allison put her hands over mine and held them there.

"Don't stop, Sis," she said and then she totally shocked me by placing her lips on mine and kissing me passionately.

I moaned and kissed her back. Her tongue pushed between my lips and entered my mouth. It snaked around inside until it found my own tongue, then they both swirled around together as our breath mingled. As we kissed, I felt her hands exploring my body. They moved down to my ass cheeks and squeezed them through my cut off jeans shorts. Then she pulled my hips into hers and started grinding on me. Electricity shot through my body and into my pussy making me crazed with desire. My burning pussy became so wet.

I lowered my head and took a hard nipple into my mouth and sucked it as deep into my mouth as I could. My teeth clamped down and I heard my sister squeal.

My mind was reeling. I couldn't believe how turned on I was ... with my sister, for cripes sake! Then, she had her hand down inside my shorts and under the waistband of my panties. I felt her fingers split my wet lips, then slide down to my opening. Two fingers pushed inside me and I gasped. My sister was finger fucking me!

Involuntarily, my hips began humping her hand. My breathing quickened and I moaned loudly in passion.

"Oh god, Sis, that feels so good," I gasped.

"Sit on my face Sis, I want to eat you," she said. "Get naked girl ... hurry!"

I lifted myself off my sister and undressed next to her bed as fast as I could, while she likewise stripped naked. Then I swung my leg over Allison's head and lowered my pussy to her waiting tongue. It started flicking and swirling over and around my swollen clit. I squealed with delight as my hips started bucking on her face.

"Oh fuck Sis, how did you learn to eat pussy so well?"

"With my friend Gale," she replied, then returned to sucking on my clit.

"God Sis, you're going to make me cum," I shouted.

I felt that special tension building in my pussy, the wonderful burning of lust spreading out from my cunt, breaking over me like lava pouring over a mountain side from a volcano. My whole body shuddered as a glorious orgasm took me. My brain zoned out as I arched my back and my legs began to shake and quiver. I screamed out my joy.

"Allison, I'm cumming ... fuck!"

Then I collapsed on my sister's legs, my face ending up on top of her smoothly shaved mound. Her fragrant musky aroma filled my nostrils and keyed my excitement up another notch. I moved my hands to her pussy and spread her labia apart, thus giving my tongue easy access to her engorged little nub. I flicked over her clit giving her the same pleasure she'd just given me and I heard her cry out.

"Oh fuck yes, Beth, that's it ... don't stop ... make me cum, girl," she yelled.

I reached under her thigh with one hand and managed to get two fingers inside her cunt and began thrusting in and out of her. They made slurping wet noises as my fingers slammed into her drenched pussy over and over.

As I finger fucked my sister and voraciously sucked her swollen clit, I felt a wet tongue starting to work on my own clit again. Waves of bliss began surging through me. Then her fingers pushed deep inside me as she sucked my clit into her mouth and clamped down with her teeth.

I came again so hard. My legs shook and quivered. I felt Allison coming at the same time under me. As so often happens when I have such an intense orgasm, I kinda blacked out for a few moments. When my mind came back around to reality, I heard a strange voice, a voice that didn't belong there.

"Well girls, what do we have here," I heard our mom's voice say.

"Oh fuck," I said, "holy shit," Allison added.

"Mom!" we both yelled.

"Although I'm a bit surprised, girls, I have to confess I did the same thing with my sister when we were your age," Mom shocked us with her admission.

"Aunt Kelly?" I asked. Mom just gave me "the look".

"Don't you dare say anything to your Aunt. And I don't mind if you two want to experiment, but just try to be a bit more discreet about it from now on."

"Really Mom? We're not in trouble?" I said flabbergasted, expecting to be grounded for the rest of my life.

"Not as long as you do a load of laundry before bedtime, cause I am sure as hell not washing all those cum stains off your sheets," she chided.

"Oh Mom ... " I said and wrapped my arms around her. Allison got off the bed and joined the hug-fest. Mom reciprocated and wrapped her arms around both of bus and hugged us back.

"Oh my god, this brings back memories," Mom said.

'What Mom?" Allison asked.

"Holding your naked young bodies in my arms reminds me of Kelly all those years ago," she said with a sigh.

Mom was hugging us very tightly, smashing my face into her ample breasts, almost smothering me.

"Girls?"

"What, Mom?" Allison said. I couldn't answer, I could barely breathe.

"Would you girls like to play with some of my toys?" Our mother said, shocking the shit out of both my sister and I.

But that's a story for another day.
