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.
