I was torn, though. With how hard her inner muscles were clenching around me, like she was trying to suck the cum out of my cock with her pussy, I knew I had to keep fucking her till I gave her everything I had.
Then it hit me like a thunderclap.
While we were busy getting ourselves off — I could be getting her pregnant! And I sure as fuck didn’t want to be having a baby with my own sister.
“Cassidy, I’m really close. Where do want it?”
“Please, Joey, come inside me. I want to feel you filling me up when you come.”
I rolled my eyes, pounding her even harder. Just the thought of pumping my own sister full of my seed was enough to start the launch sequence in motion.
I was thrusting like a mad man, pistoning in and out of her clenching cunt. When I felt the most explosive rush, I’d ever experienced shoot right down my spine and out of the end of my cock; filling her pussy with probably the biggest load I’d ever shot.
Flexing my hips, pumping in and out of her, knowing I didn’t have much left in the tank, I pulled out. Wrapping my hand around my pulsing dick, I jacked the last few spurts over her heaving tits, making her laugh and shiver at the erotic sight of them dripping with my cum.
The way she was smiling into my eyes as she slid her fingers over her heaving tits, coating herself in my baby batter, I couldn’t believe that she was actually getting my cock pulsing again. Probably from the thought of sliding between her big, heaving titties, and gifting her with a shimmering pearl necklace.
Sitting back on my haunches, I shook my head, thinking how crazy it was that I’d finally given in and just fucked my own sister.
Though, I took some comfort in the fact that she was hardly a kid anymore, and obviously wanted it as much as I did, since she was the one who suggested we come back here.
Then my eyes popped as I watched her get down on her knees, and slip me between her lips, smiling up at me as she licked me clean.
I just couldn’t tear my eyes off her, she just looked so sexy, the way she was worshiping my cock, licking and sucking and rubbing it all over her luscious lips, before coyly sliding it over her outstretched tongue.
Playing with her nipples while she was enjoying stretching her lips around me and sucking me back, I could hardly believe we’d crossed the line and had sex. If that wasn’t enough to wrap my head around, it was even crazier that she was topping it off with a blow job, happily smiling around my rapidly swelling cock.
But at least she’d be here for a while, so maybe if we found a way to be alone again, we could try a few more things that I knew we’d both enjoy. Like a little 69, or some doggy-style fun.

Next morning, I’d just walked out of the bathroom after having a shower. I was heading for my bedroom, with just a towel wrapped around my waist, and Cassidy tugged me by the arm and pulled me inside my room.
“They’ve gone out shopping, and they won’t be back for hours,” she informed me with a naughty little grin lighting up her face.
Cocking an eyebrow, happy to hear that the folks were out, I let the towel drop to the floor.
I laughed at the way her eyes popped when she got her first look at my morning wood, standing straight up in the air, already pulsing.
“Then I guess you’d better get down on the floor on your hands and knees,” I told her, sliding my glistening friend through my fist, already imagining how incredible it would feel to pound her tight little pussy from behind.
Silently nodding, she whipped her little pink nightie over her head, letting her tits bounce free. And then surprised me when she dropped down to her knees, wrapped both hands around me, and took me into her mouth.
Holy fuck, what a feeling. And what a perfect way to start the day.
Twisting her long blonde locks in my hands, as she bobbed her head up and down on my cock, I so happy that she’d come to visit, especially now that I’d discovered what a little sex fiend my kid sister really was.
Oh, man, what a jaw-dropping feeling. I could feel my legs shaking, as I shot a nice heavy load down her throat. And I knew for the next few weeks, the two of us were going to have the best time together.
Providing of course, that no one else found out what the two of us were getting up to.
When she finally pulled back, wiping a hand across her lips, she smirked and reminded me of something I almost forgot.
“And you know my twin sister Kendra’s just finished her exams. So, she’ll be joining us tomorrow. And I’ve got a feeling that the three of us are going to have a really good time together.”
I looked down at my dick, and I swear the little bastard was already pulsing, just imagining the fun he could have with two kinky sisters like her.
