I came in from Football practice, knowing that I would be alone with my sister Kip. Dad was in San Diego on business, and since Mother took Columbus Day off to be with me, she had to work late showing houses.
Today I skipped hanging out with my friends at the burger joint, because I wanted to have a little chat with my sister. When I got home I didn't see my sister, so I thought she may be downstairs in her room. I opened the door to the basement and headed down stairs. The closer I got to my sisters room the louder I heard what sounded like a movie, and I surmised it was an x rated movie, (You can always tell because the music is cheesy and loud.)
I got to her door and it was open a crack, when I peeked in, what a sight my sister was. There she was laying on her bed, her skirt up around her waist, her legs spread wide, feet flat on the bed and she had her vibrator slamming in and out of her cunt with one hand and she was pulling her nipple with the other.
Maybe I should describe my sister; She was 20 years old, an absolutely angelic face, light brown hair and green eyes, like pools of water. She was a little on the plump side. Maybe 5'-7", and probably weighed 160 -170, she had huge tits, I am guessing DD, but were softer and hung lower than mom's. Big aureola, I am guessing about 3 inches around, long hard nipples and she had a big soft ass. Overall she was really a stunning girl.
She was so engrossed in fucking herself she didn't hear or see me looking through the crack of her door. Not only could I see her clearly, but I could see and hear the movie she was watching, and it shocked me a little. There on the screen was an older woman, perhaps 40's and a young woman maybe 18 or so, and at that moment the older woman was squatting over the face of the younger one and grinding her cunt and asshole in the young ones face>Telling her, "Eat Mommy's cunt baby, show Mommy what a good little cunt sucker you are."
Kip was moaning loudly watching and hearing this, jamming that vibe in her pussy, yanking and twisting on her nipples. I hear her whisper, "Oh yes mommy, make your daughter eat that cunt."
I couldn't believe my ears, not only did she love fucking Dad, but she was masturbating thinking about fucking Mom too, damn she was a fucking little cum slut. I opened my fly and pulled my long hard cock out and was stroking, spitting on my hand and jerking it hard and fast. Fuck I was horny, I didn't get the chance to fuck Mom and didn't even get a blow job before she left this morning.
She was grinding and moaning so loudly, I knew she was nearing her orgasm, so I stepped in her room. "Hey little sister, what a fucking slut you are."
She looked over at me like a deer caught in the headlights. Quickly pulling her skirt down and trying to cover her massive tits. "WHAT THE FUCK ARE YOU DOING IN MY ROOM DICKY?"
"Calm down slut, just calm down." I stepped in her room, my big fucking cock swinging in front of my pants.
She caught sight of it and said, "DON'T CALL ME A SLUT AND GET THE FUCK OUT OF MY ROOM."
I walked over to her, slowly stroking my huge hard on, looked down at her as she tried to curl up in a fetal position. "Don't pretend with me my little slut of a sister. I saw what you and Dad were doing the other day."
She looked up at me scared now, "What are you talking about Dicky?"
I laughed as she was staring at my huge fucking cock, "I saw Dad fucking you and believe me you were enjoying it slut, I heard you telling him to fuck his little girl, I know what you are, so drop the pretense sis."
She was tearing up now, "Dicky, you can't tell Mom, you just can't. She will kick me out and have Dad put in jail. You know Daddy doesn't get any pussy, and I felt so sorry for him. "
I settled in the chair near her bed, still looking at her beautiful body, she relaxed her arms now and I could see her hard nipples, "So tell me sis, how did this get started, did he come on to you, or the other way around?"
The tears drying up as she relaxed a little, "I caught him looking at porn of women about my age, jacking off. I felt sorry for him and offered to suck him, he was hesitant at first, but I showed him my tits and I dropped to my knees and crawled to him. He spun his chair around giving me access and I started licking his dick, then sucking him."
I was stroking harder now and I could see she liked watching me, she had her hand under her skirt, and was jamming her fingers in her pussy as she was telling me. Her words getting more nasty as she fucked that cunt. "Go on my little cum slut of a sister, tell me more"
"I couldn't believe how turned on I was, my pussy was creaming in my panties, I pulled my little skirt up and yanked my panties down so Daddy could see my little pussy, I jammed two fingers in my hole, and I came with him as he shot his load all over my tits. "
Standing and walking to the side of the bed, lifting her skirt so I could see her finger fucking her pussy. "You are a fucking slut sis, and I love it."
"Please tell me you won't rat us out. I will do anything, you want. I will clean your room every day, do your laundry, you name it, I will do it for you, just don't tell."
I looked at her and saw her cunt so fucking wet, sloppy wet sounds coming from between her legs as she fucked that hole, "No Sister, I have something better for you to do for me. I will keep your secret, as long as you do everything I tell you. Otherwise I spill the beans and you are out on your ass, and well no telling what will happen to Dad."
She looked up at me, and smiled, "Anything, anything brother, anything you say."
I smiled at her, grabbed her by her long brown hair, pulled her to me, "Glad you said that sister, now suck your brothers cock."
She grabbed that big meat stick and licked the head, sucking the precum, licking slowly sideways along the length down to my big hanging balls, lapping and sucking, chewing on the side of my fat cock, moving her lips to the head. Hovering over the head she allowed spittle to dribble from her mouth on the head and slide down the shaft, "Oh fuckkkk sis, you are such a good little cock sucking slut."
She pulled my cock in her mouth with one hand and slipped her other around to my ass, lightly pushing her fingertip over my puckered asshole, I slowly started moving my hips fucking her mouth, reaching down and shoving two of my big fingers in my sisters cunt.
She moaned out loud and jammed her mouth farther down on my cock, choking a little, gagging, as spittle came out of her mouth, She pulled her mouth off my cock, "Finger fuck your sister Dicky, jam those fingers in my little cunt brother."
I pushed three fingers in deep and rolled my thumb over her clit, finger fucking her deep and hard, groaning as I felt my sister throat my fat cock. "Damn sis, I fucking love how you suck my dick, no wonder Dad made you his nasty little fuck slut."
When I said that she drove her cunt on my hand, jamming my fingers deep in that bald cunt and started cumming. My cock still in her mouth all I could hear was, "Garrrrrrrrrrrrrrrrrrrrrrr. Mmmmmmmmmmmmmmmmmmmmmmmmmmmmm, Ohhhhhhhhhhhhhhhhhhhhhhhhhh.
I didn't let up, my hand wrapped in her hair fucking her throat ad she was cumming all over my hand. When she stopped humping my hand, I pulled my fingers out and wiped her cum on my cock and her mouth. "So fucking gooooood my slut sister, Mmmmmm."
I backed away from her, and crawled up on the bed on all fours, she looked confused until I told her, "Lick my asshole sis." I thought this was where she would balk and I would have to remind her what I held over her head, but she crawled in behind me willingly.
"Such a good slut for me sister." I looked over at the mirror and I could see her big tits swaying as she pulled my ass cheeks apart. I felt her tongue swirl around my hot shit hole and when she moaned I knew she loved it.
