“W-w-what?” I stutter weakly, scrambling to grab the remote control while my trembling body teeters upon the very edge of giving in to a massive orgasm. What isn’t helping is that Ella’s clearly already in the midst of her own climax, and her tight pussy’s fluttering around my embedded cock in a way I’m finding impossible to ignore!
“Pee break,” announces dad.
“And I’m going to get a drink and some munchies,” adds mom.
As the two of them turn towards the sofa with me and Ella lounging on our sides, a huge smile spreads across my mother’s lips.
Shit – she’s looking at us, and she’s actually smiling!
“Aww, isn’t that sweet! I haven’t seen you two that comfortable with each other in years. You’ve both made up now, I hope?”
I wrack my short-circuiting brain for something intelligent to say, but with all my concentration going to holding back a nearly unstoppable orgasm, coherent thought is way down on the list of mental processing priorities. And yet, despite being in the tail end of her own orgasm, Ella is not only capable of speaking, but knows exactly what to say to quell any suspicion.
“Oh – you know about our little tiff?” she asks levelly.
“Oh, sure. A mother always knows about that kind of thing. I don’t know what it’s about, but have you two settled it yet?”
“Eh... I dunno, mom. I’m still totally pissed off at Tommy, and he’s still my knucklehead brother... but right now, he’s like this cozy hot water bottle keeping me toasty warm.”
She’s gonna be heated from the inside out if I can’t hold this thing back!
Mom shivers. “Yes, it’s gotten really chilly in here, hasn’t it? Can’t understand why your father shut the heat off already. It’s still April for goodness’ sake!”
“Saving money, dear!” calls back dad, who’s already halfway down the hall to the bathroom.
“And freezing us all out in the process!” shoots back mom. “Well, anyways, you two look just too cute together for words. I should get my camera and memorialize the moment! Knowing how much you two fight, it might never happen again.”
At that precise moment, the lewd knowledge that my mother is not only looking at the two of us locked in coitus and doesn’t suspect a thing, but even wants to take a damn photo of it for the family album, pushes – no, hurls – me clear over the edge. With my face flushing hot and my aching balls pulling tight against my body, my stalled orgasm hits me like a runaway freight train.
With a whole-body convulsion that quite literally takes my breath away, a mighty geyser of thick semen rushes into my urethra and ripples almost painfully along the length of my cock, until erupting deep into the furthest recesses of my sister’s pussy. Beneath the blue blanket I involuntarily twitch my hips against my sister’s ass, feeling our soaking wet skin squishing and sticking together in the most gloriously obscene manner, while my cock pulses and throbs and sends volley after powerful volley of teenage cum flooding into her virginal womb... all while our mother beams proudly at the two of us.
Oh my god! I’m ejaculating inside Ella while mom watches it happen! Holy shit, this is bad!
Focusing on me, mom’s smile turns into a mild frown. “You okay there, Tommy? You’re looking a little flushed. I hope you’re not coming down with something.”
“Oh, he’s fine,” responds Ella. “He’s just embarrassed that you caught him doing something actually nice for his little sister. Isn’t that right, big bro?”
Ella turns half over to look me in the eye, resulting in her ass pulling away from my heaving body just a little – which turns out to be a mistake, as an audible eruption of something hot and wet immediately squeezes out from around my cock, as if my physical presence had been holding it back like a cork in a bottle.
Thankfully, mom doesn’t hear the noise, but the sudden panic that she might is enough to bring a speedy end to my mind-blowing orgasm.
“Y-yeah, whatever,” I mumble a little hoarsely, praying that my sister doesn’t move any more. “I didn’t get Ella a proper birthday present, so now she’s taking it out of me in other, far more embarrassing ways.”
Ella giggles. “You sure got that right, hot stuff!”
Mom laughs and then continues on to the kitchen, leaving Ella and me alone in the living room.
“Hey, is that true?” she asks the moment that mom’s out of earshot.
“Is what true?” I groan, still finding it difficult to come to grips with what’s just happened. How can Ella act so freaking calm? Doesn’t she know what I did?
