I sat in Karen's lap for some time, gazing with love at my little sister's beautiful face. A sheen of sweat glistened on our naked bodies. Her cheeks were flushed with passion, and a warm smile graced her beautiful face as I thought about the huge load I had just blasted into her mouth and she had hungrily swallowed.
I bent towards her and our mouths met in a hungry, fiery kiss. I could still taste traces of my semen in her mouth as our tongues wrapped themselves around each other. We kissed long and hard, the heat of our bodies against each other fueled our passion.
"You're a warped little girl, you know that Sis?" I kidded. "So you think I should take advantage of my own daughter, huh?"
"Ha ha, you love it!" she replied. "And she needs it waaayy worse than you do. You have a little sister that will suck you off and fuck you whenever you want. All she has is her fingers, your picture, and that Trevor character, who squeezes her boobs like he's milking a cow. She needs your cock, Bro. I think you'd be really doing her a disservice if you didn't give it to her."
"OK, I can see that you're serious. I love Marisa, but believe me when I say I've never EVER allowed myself to think of her that way. But you're right, we're brother and sister, and we fuck like rabbits. I guess it's sort of hypocritical of me to start drawing lines if she's of legal age. How do I, uh, you know, hit on her?"
My little sister broke out in a fit of laughter. "Oh my god, Bro, you are so cute... you sound like you're her age."
I snorted. "Well, this isn't exactly your standard dating scenario. I'm relying on you being right about her having the hots for me."
"It's simple, really, Big Brother. You already do everything for her she needs. You know she's upset lately, right? Just invite her for a chat and have her sit on your lap. You know how she loves that! Cheer her up, tell her she's beautiful, then start tickling her. She'll be laughing, giggling and squirming against you in your lap! Her pussy will be hot and moist. It shouldn't take much to shift things into a sexier vibe. It'll be like taking a cherry from a teenager!"
"God, Sis, you make it sound so easy!" I exclaimed. "I wish I had your confidence..."
My sister talking about my daughter like that had my cock stiffening again. Karen didn't fail to notice that development, and reached out and started stroking it.
"Seriously," she stated, "this is going to be easier than cougar hunting at male strip clubs at closing time. You can't fail. But I see you have a growing problem here that needs attention. My pussy is on fiiiiiiire, and you need to stick that cock into your little sister's cunt and fuck her real hard, right now!"
I laughed and grinned at her. "You're really in a mood tonight, Little Sister! OK, your big brother's going to stick his cock into your snatch and pound it like a steam engine!"
She spread her legs wide and I placed the head of my cock at her lips. She was slick and hot, and in one thrust I slid to the hilt inside her. She exhaled at my insertion, and the look of pure lust on her face made me want to fuck her into oblivion.
"I love you, Big Brother," she moaned. "Fuck me."
I started slowly pistoning my shaft in and out of her dripping pussy, savouring the sensation on my penis. She was so wet that I was already making squishing sounds as I fucked her. Since I had just shot a load in her mouth, I had more staying power this time around, so I set to the task of thoroughly fucking the shit out of my baby sister.
I grabbed her thighs and scooted her butt closer to the edge of the couch, spread her wide and really started driving into her. My balls and pubis were making slapping sounds against her pudenda and buttocks; small mewling gasps started coming from her throat. My little sister makes the sexiest noises and faces when she's being fucked, and right now she was kicking me into super overdrive!!
My cock was tingling as I started hammering into her twat, my prick slicing into her like a hot knife into butter, slapping and squishing noises attesting to the fury of our passion. I drove deeper and the helmet of my dick started beating against her cervix.
Karen started crying out, "AH! AH! AH! AH! YES! YES! GOD YES! FUCK ME! AH! AH! YES! GOD, FUCK ME JUST LIKE THAT!!!" I didn't think I could get any more turned on, but her words drove me to new heights of lust!! I looped my arms underneath her thighs and lifted her so I could stand on my feet with my legs bent. I drove my rod into her quim with a fury, ramming into her as fast as I could, my glans battering away at her cervix and g-spot, causing her juices to start leaking out all over her ass.
Her gasps and cries started building up into a keening wail. If there were any neighbours anywhere near the house, I was sure they must have been able to hear! "OHHHH FUUUCK, BRO, I'M GONNNA CUUUMMMMMM!!!!!!" she screamed, her head thrashing back and forth, her eyes shut tight and her hips bucking wildly.
"AAAAAHHHHHHHHHH!!!!!!" she howled out as her pussy clenched down hard on my dick. I huge spray of girl-juice shot out of her pussy, spattering all over me and onto the throw rug and couch. Her hands were flailing around and grabbing onto anything they could, the cushions, her hair, her boobs, my shoulders, as she convulsed and writhed as she came all over my cock.
I started slowing my pace and her eyes snapped open as her mouth gasped for air. "OK! OK! OUT! OUT! ENOUGH!! I CAN'T TAKE IT!!!!"
I withdrew my cock with a grin as she shuddered, her head rolling around and her eyes blankly staring at nothing. "Was that good, my sweet little sister?" I asked her.
"Fuck." She replied, panting. "Fuck, too good. Soooo fucking good. I haven't cum like that in a long time. Wow, did you fuck me good!!"
I just laughed as she gasped and heaved. "Ooooh, fuck, I can't stand up!" she laughed. "Oooh, too sensitive. Wow, I'm vibrating." She made half-hearted attempts to stand, then gave up, lying on her side curled up, shivering. "Hmmm, you need to cum, huh, Big Brother?"
"I'd love to, Little Sister," I said. My cock was glistening with her juice and pointing towards the ceiling.
"Why don't you fuck me up the ass?" she invited. "That would be soooo good right now, and I, uh, sure squirted out enough lube for it."
"Fuck, Sis, you are a wild woman tonight! OK, I'm in! Get your ass ready, here comes my cock!"
She rolled over on her hands and knees, spread her legs and thrust her butt in the air. Then she started running her fingers over her butt and thighs, moistening her anus with the juices. She then gently stroked her labia, shuddered, and started inserting her fingers into her asshole. There was so much of her juice that in no time her fingers were slick and sliding into her rectum two, then three at a time. My dick was hard as steel and throbbing. I scooped some of her juice from her thigh, causing her to jump a bit, and rubbed it all over my shaft. She spread her legs wider and pushed her butt up and out more.
