For the most part, it was a slow day for the those working at Brimstone Pizza, barely any orders going out and nothing good to watch on TV...

...all except Lilith however

In a moment of weakness, she had ended up 'sampling' (aka, eating 3 slices) of a specially-prepared pizza that had been left out upon the counter unattended. Despite the specific warnings on the front of the box that detailed it as *SOLELY* for the customer,  the hunger was simply too much for the demonic gal, having skipped breakfast and with her gut now groaning. 

By the time she's finished with those those odd-tasting slices , she nearly doubles over in surprise when she feels an incredible amount of warmth begin to build up at her crotch.
With a look of sheer terror upon her face, she shuffles her way towards the employee restroom with panic coursing through her veins. SLAMMING the door shut behind her, she can only moan in disgust at how she effectively did this to herself, looking down at her crotch and grimacing at the sight before her. As soon as the door closes behind her and she hears the 'click' of the lock...her newly grown endowment makes itself present. 
Sounding out with a cacophonous *RRIIIPPPPP*, the sanguine red fabric of her dress completely parts to reveal her staggeringly large, 3-foot long aching horse cock. She gasps at this, mouth open wide and pupils looking miniscule as she tries to somehow make sense of what has happened to her, palms going lax at her sides as that impressive girth juts out at full mast. Thick, throbbing veins criss cross down the sides of her equine rod, sending chills through her frame as her tail tenses up in response, eyes soon enough watering from the feeling of the cold air hitting that nearly-ebony-black horsecock.
"Wh...how...why is this happening?!?" she moans, vision going partly blurry , unable to properly focus her thinking as every passing second has her stimulated girth even more throbbingly erect.  Lilith, with eyes watery and heart racing, can only utter a low, nearly inaudible MOAN as her fingers brush against that obscenely flared tip. Near instantly, she's lost to her own lusty desires, body trembling and soon enough coated in sweat as her palm is quick to grip onto her thick, meaty cock. Holding tightly onto that massive horsedick, precum pours out of the thick, puffy cumslit tip with a consitency similar to corn syrup, the translucent gunk sliding down the sides of her tremenodus length while she struggles to even keep her body upright . "nnghhgh" echoes from her lips as her eyelids flutter, both palms gripping tightly onto her impressive shaft, feeling firsthand how impressively firm that medial ring has become already. Unseen by her gaze, below that gargantuan cock her balls start to hang oohhh so very low, swelling and bulging outwards as they jiggle about with unbelievable weight. With every passing second her palms slide up and down that steely hard girth, they appear all  the more larger, pulsating and throbbing as she shudders in response to the audible sound of spunk -SLOSHING- about within those heavy, heady orbs. 
The effects of the pizza thankfully, are short lasting, for it doesn't take long before just rubbing and caressing her newly grown horsedick has Lilith on the very verge of orgasm. Bringing one pre-soaked palm to her chest, she slips it underneath her sweaty dress, squeezing those engorged nipples in sheer lust as she rapidly grinds and kneads her fingers into surface of that aching prick of hers. Sweat soaks her frame, her glasses effectively fogging up as she sighs and drools at the unbelievable feeling of jerking herself off, body trembling and shivering with every instinctive pump of those wide hips .  A spasm wreaks havoc upon her frame as she at last hits her limit, bringing her palm right to the base of her massive girth and standing still for a few minutes...
all as he completely COATS the wall in front of her in a torrent of hot, freeflowing sperm. It gushes out of her prick in a continuous stream , looking as though it was being sprayed out of a garden hose even as that hot, buttery sperm glides its way up her shaft and audibly *sPLURTs* out into the air, arcing downwards and landing all over the area directly in front of that powerful phallus. Sighing and struggling to catch her breath, her orgasm slowly starts to die down as time goes on, cock bobbing in the air less and less as her tongue flops out over her lips, mind finally at ease as she slumps down directly onto the ground with a wet thud. So very exhausted from such an intense, unheard of experience, she's left unable to move from the spot too, legs spread and head slumped to the side as her slowly-shrinking shaft lets out the remnants of its load into a creamy puddle directly beneath her temporary, throbbing endowment~

(EPILOGUE)
Maxwell,  returning from their lunch break, can only offer a look of sheer surprise when they see the opened pizza box out upon the counter
"Uhhh...Hal? Did you take a few slices from the ..'sardine-infused' order?..."
"W...Wait...Sardine?...I thought that they had ordered it 'Equine'...uhm......woops...."
.....don't eat that by the way..."
