You stand transfixed with admiration and longing, baseball shoes dangling from your hand. Even as blood rises to your cheeks -- together with guilt for your voyeurism -- you can't take your eyes off the two beauties subtly grinding against each other. Alexis, the slightly taller girl, breaks off the kiss for a moment to turn on the shower, adding the sheen of water to their already glowing skin.
She brushes Lilly's dampening hair from her face and kisses the giggling girl on her forehead. Her other hand traces the flow of water down her back, until it squeezes a fat, glistening buttcheek. Lilly reciprocates, running her hands from Alexis' hips back around to fondle her ass and pull their wet bodies closer together.
You feel weak, your breath catching in desire. While they might not have heard that over the splashing water and their lusty moans, they definitely hear the heavy cleats slip from your fingers to thud and clatter on the locker room floor.
"Oh shit." You clap a hand over your mouth in a futile gesture. The blood drains from your face for a second in fear of discovery, then comes rushing back as two pairs of bright eyes turn towards you. You are suddenly, painfully aware of your dick bulging against your briefs.
"Oh?" Lilly's startlement is brief. Her lips curve into a hungry smile; her coppery eyes kindle with lust. "Oh. What do we have here?"
"I-I-I- sorry," you stammer, shuffling and mentally cursing yourself. "I-I didn't -"
"Look Lexi," she cuts you off, "a naughty boy perving on naked girls." She runs her hands across the top of her slick breasts, flicking droplets from the hard, pale pink beads of her nipples.
Are her boobs getting bigger?
"Ah-ah-an accident --" Something is wrong here, but your mind is too addled by shame and the throbbing in your pants to place it. Trying not to embarrass yourself even more, hoping against hope that this is your chance --
Your eyes snap to Alexis as she interrupts your stuttering.
"Of course," she purrs in a sophisticated, slight British accent. "No harm done." Her smile is confident and reassuring, but her eyes... they mesmerise you as they change from hazel to pale gold.
"You're Joe, aren't you?" You nod heavily. She pulls Lilly to her with one arm, her right breast squishing lightly against Lilly's left as they swell against each other; with her other arm, she beckons you to them.
"Would you like to join us? There's room for one more."
You take a few steps forward, enraptured by her smooth, honeyed voice. But then you see her outstretched hand darken; claws form on her fingertips.
You stop.
"Wh-what...?" Your eyes widen as you see fur, black fur, glove her hand up to her elbow, where it shades to a smokey red.
She laughs. They both laugh as they turn fully toward you. Black fur covers all of Alexis' front, her nipples darkening to a shiny black-red atop expanding breasts. Lilly's neatly trimmed pubic bush turns from red to white; the fur spreads out over her belly and inner thighs, while her clit begins to swell out from her hood, a bulge forming below it and pushing it upwards.
"Oh my God?" You take an uncertain step backward, horrified but still horny, not even sure what you're seeing. The girls step out of the shower stall towards you, sure-footed as their feet bend upward, balls and toes growing into large, padded black paws, heels shifting into powerful hocks. Their faces push out into long, narrow snouts; Alexis' tongue slips out, thin and dextrous, licking her chops in anticipation. Their ears push up, tall and velvety and pointed in eager dominance: Alexis' black in her now-wild mane of silky black hair; Lilly's orange tipped with black amid her auburn locks.
They separate as they advance on you, their swaying hips emphasised by emerging tails behind them. Lilly's is orange tipped with white, Alexis' is dark red tipped with black. Taller with every step, their enhanced muscles are hidden by even fuller curves. Alexis' bust grows from D to E and on to F, round and perky; and as they do a second pair swells out beneath them, equally firm, and soon the original size of her first pair. Lilly's near-Cs grow out to double-Ds, a new pair of Cs nestling beneath them. But that's nothing compared to...
"Oh my God!"
There's no mistaking it now -- even your muddled brain can't fail to see it: Between those thick thighs swing heavy ballsacks, growing larger and tighter by the second, the girls' dripping pussies concealed behind them. Above them stand proud, pointed spires: Lilly's rises in a graceful arc towards her boobs, thick knot below slender tapering shaft, seven inches of smooth, glistening red fox meat; while Alexis' longer prick points almost directly at you, eight or maybe nine inches of menacing, thick throbbing fox meat, red-black like her nipples, the fat surface coated with the pre drooling from her tip, the knot at the base seeming as big as your fist.
"Amazing, aren't they?" The purr in Alexis' voice is now a predatory, possessive growl. "Imagine. haaahrr... what they'll feel like inside you." Her breath huffs as she wraps a hand around her heavy tool and squeezes, but she doesn't miss a beat in her seductive stride.
You shake your head. But as much as you want to, you can't bring yourself to back away. The scent of wet fox, saturated with male and female musk, wraps around around you. Powerful, rank and yet... it awakens something primal within you that adds fuel to your lust even as it saps strength from your limbs. You feel like prey, mesmerised by the scent, and the slit pupils of the fox-girls.
"Uh... I..."
"Aw, what's wrong, little boy?" teases Lilly. She sets her hand on her top pair of breasts, running them down, moaning as she touches her nipples, before moving on to her second pair. "Jealous?"
Little!? But you realise with a start that, while you were taller than them initially, Alexis now towers over you, and even Lilly surpasses you by at least two inches. Never mind how their knotted vulpine rods put yours to shame.
"Don't worry," the shorter vixen croons, her cock clenching out a dollop of thick pre that runs down along its erect length. "Mnnn, soon you'll have your own..."
Your mouth is dry, your throat too tight to do anything but whimper hoarsely. Oh God what does she mean by that? The stalking vixens, now fully transformed, are almost on you. Lilly approaches on your left, her threat lingering around her in the earthy-sweet cloud of her musk; Alexis advances on her left, slowly pumping at her massive, knotted cock.
Come on, run! But your legs are trembling with fear. And desire. Your stomach twists in revulsion. You can't believe you're still turned on by this; you ought to be disgusted at the blatant display, the overabundance of sexual organs. But somehow, the sheer raw power of their display is overwhelming your mind. Despite yourself, you admire them even more, and that buried part of you now shaken loose wants to feel those cocks. Smell them.
Maybe taste them.
But the more rational part of your mind is still defiant. It is not ready to be fucked by four-titted anthro prickvixens, and it is afraid of what might happen to you if you are. If you turn and bolt, you might surprise them and make it to the door. Some other guys from baseball practice should still be out there to hear your call for help -- if you can make it.
