Growing up in a three bedroom house with a younger sister and younger brother you learn all about each other over the years. What annoys whom, favorite types of blankets, senses of humor, everything. My little sister thankfully is a sweet and charming girl with a petite build, dark hair she switches up all the time currently rocking bangs. She's helpful, independent and never needy. I know her as well as anyone could. Or so I thought. Two nights ago I learned she loves cock. I mean, most people like sex, but I've never heard anyone beg for dick like I heard her do to her boyfriend. I guess she can be needy. And by the way the door slammed as he left her room and the house, she can be feisty too.
I was just at my parents house to grab my golf clubs and a drink which she clearly didn't expect, walking out to the kitchen frustrated in just a tank top muttering "fucking pathetic," until she looked up and saw me leaning against the counter taking it in.
"Oh my god!"
She tried to cover herself but it was too late. I already knew by now she had a bald pussy with puffy pink lips, a dirty mouth, and was a horny 18 year old girl. My cock stretched my joggers as she turned away and ran to her room. I followed close behind and stopped the door from closing as she collapsed on her bed spread eagle, pulling her discarded pink panties over her gash as she heard me come in.
"I'm not a slut if that's what you think."
She continued as I stood in awe.
"Is it too much to ask for a fucking orgasm? Jeff comes and gets soft before I've even gotten close. Sorry you had to hear that."
"Doesn't he eat you out before he sticks his little prick in?" I jokingly asked and stepped towards her.
"Oh he tries but he suuuucks!"
Her panties did little to cover her at this point and I saw how wet she was.
"What a shame. I would make you scream before you even felt my cock." I can't believe I said that.
Her hand pulled away from her sex and she said exasperatedly, "Then let's see."
"Are you serious?" I was almost lost for words.
I looked down at the dark pink folds protruding from between her labia, glistening with wetness. Her clit was clearly engorged on top of her little slit. My mouth was watering.
"Fine, I'll just use my trusty vibrator then..."
"No stop. I'll take care of you, sis. You want your big brother to show you how it's done?"
She slid her middle finger inside her wet hole, and I didn't wait for any more confirmation.
I got on my knees between her legs and sucked her engorged clit and started fingering her without a second thought. She bucked against my face as my tongue circled her nub and licked down her slit and across her pussy. I was shoving two fingers inside her and nibbling her clit when I felt the gush of her long awaited climax on my face and kept going, lifting her ass up to tongue her pussy underneath as she panted. I went back and forth nibbling her clit and licking her slit as my fingers slid inside her pussy then down to her ass.
"Uhh" I heard her exclaim in surprise as I lubricated my finger inside her soaking cunt and pressed it against her tight bum.
There was a slight pause before my first knuckle pushed in her ass hole, then she was all mine. "Fuck me please, Jack"
I kept fingering her ass and slid my other hand inside her tank top to grab her little breasts, pinching her rock hard nipples before sliding her shirt up to give me full view of her naked front side. What a sight. My naked little sis was sprawled in front of me lost in lust, begging for my cock.
