Humming to hirself, Antonya makes hir rounds around the bar as it closes down for the night, collecting the used glasses and bringing them back to the bar to be washed.  The cute little white mouse squeaks as one patron, a large golden gryphon, grabs the back of hir skirt and tugs gently, snagging hir panties as well, pushing a note down between hir asscheeks with a loud purr and a lewd wink.
Blushing hotly under her soft, well-groomed fur, the little mouse dances away, forcing a friendly giggle. "Thanks for the tip, Mister! I hope you have a good night!" She smiles to the gryphon, then gasps lightly as hir shorter stature gives hir an excellent view under the table, seeing the gryphon lazily stroking his large, thick, knotted penis, oozing precum slowly, drooling a long, clear string towards the floor.
Staring at the sight, having problems seeing how it could fit in anyone, let alone hir little body, Antonya squeaks softly in shock, making the gryphon chuckle as he tucks his cock away before standing, swaying a little on his paws, swaying drunkenly as he leaves, muttering over the music as he passes the mouse. "I'll see you later, mousie..."

By the time Antonya finally finished work, she was exhausted, not bothering to hide hir wide yawns as shi waved goodbye to her co-workers as left the bar to walk home.  To hir surprise, the gryphon had been a generous tipper.  Instead of the five dollar note shi had been expecting, shi'd found a fifty, which at least made up for the sight under the table.  The large tip shi made that night put a spring in her step, and shi wasn't prepared as a large arm snuck out of the alleyway and grabbed hir by the collar, dragging hir into the dark shadows.  As shi opened hir mouth to protest, a ball of cloth was stuffed in, the musky scent and taste on it making hir gag as the much larger figure restrained hir arms behind hir back with ease.
Shi felt hir skirt being lifted up and a strong talon wrapping around hir leg, forcefully pulling them apart.  Even in the dark, shi recognized hir assailant as the gryphon from the bar, whimpering as he released hir leg and reached up to snag hir panties with a claw, tugging and ripping at them until it was little more than shredded cloth.  Remembering the size of his hard prick in the bar, shi whimpered loudly as shi heard him unzipping and dropping his heavy jeans to the ground.
Though shi didn't dare to resist, the tiny little mouse shook hir head as shi was turned around to face the wall, the gryphon panting heavily against the back of hir neck as he pushed hir hands against the wall and pushed his hips between the mouse's legs, making Antonya grunt as they were overextended.  Shi felt the heat of his cock before it touched hir, slimy with precum and sheath-lubrication, the heavy, pointed tip pressing to hir labia and grinding slowly, splitting the soft lips apart.
Antonya squeaked in shock at the sudden intrusion, her sensitive folds burning under the hot, throbbing shaft as it slid past, stretching out hir inner walls and making hir gasp. Shi was surprised at how easily he filled hir, feeling the gryphon stretch hir slick tunnel and push deeper, the sensation making hir squirm and squeak into her impromptu gag, whimpering and squealing as the gryphon pulled hir closer, pushing his hips towards hir.
Hir legs trembled as hir toes curled, hir breath coming in short pants as the gryphon held hir tightly against his body, gripping hir waist and pinning hir there against the hard wall as he began thrusting roughly into the tiny mouse, pounding into hir tight little pussy with a powerful, swift rhythm. Shi wiggled helplessly, whimpering and moaning into the gag as the gryphon mercilessly pounded hir, hir insides clenching spasmodically under every thrust, unable to get any relief from the constant friction.
"Oohh... yes, like that," The gryphon growled and pulled back slightly, before thrusting even deeper, hammering his prick against Antonya's cervix, nibbling on one of the mouse herm's large round ears, working a hand between the wall and her to hold hir little belly. "Fuck, yeaaah... Got a big load of cum with your name on it, rodent... Can't wait ta dump this allll inside yer little body..."
The gryphon grinned wickedly at hir, his hips bucking faster and harder, driving his thick cock deeper into the little mouse, Antonya grunting and squirming in the gryphon's grip as hir insides tightened around the gryphon's thick shaft, hir body wracking with pleasure as the gryphon continued slamming hir with relentless force, the mouse moaning and crying into the gag as hir orgasm built up within hir. Hir muscles squeezing the gryphon's cock harder and harder as the gryphon's pace increased, his huge cock driving deep into hir body with each stroke, the thick shaft leaving a trail of wetness as it slid in and out of her dripping pussy. Hir eyes widened in fear and hir body trembled as shi heard the gryphon whisper darkly in hir ear.
"Get ready, mouse... I'm about to knock you up..."
Antonya screamed into the gag, the gryphon grinning nastily as he slammed into hir again and again, hir insides tightening and milking the gryphons cock as he fucked hir hard, his rough, demanding strokes making hir body shake and tremble as hir orgasm built up yet again, hir moans and whimpers muffled as the gryphon leaned forward, biting hir ear as he rammed hir so hard, her insides clamped down and shi screamed through the gag.
"Cum for me, rodent... Cum for meeee..."
Antonya sobbed silently, shivering as the gryphon pulled back, his cock twitching and jerking as it spurted its load of thick cum, filling the little mouse's womb with the warm, sticky substance. Shi shook and sobbed uncontrollably as the gryphon grabbed hir hips, holding hir still as he pumped more and more seed into hir, his cock swelling and pulsating powerfully as he emptied his balls.
Finally, after what seemed like an eternity, the gryphon finally pulled back and held hir tightly, panting heavily as the last of his cum leaked out of hir pussy, coating hir thighs with the sticky fluid. Antonya gasped and whimpered, trying to catch her breath as shi felt the gryphon reach down between their bodies, grabbing hir panties and tugging them off, tucking them into his pocket as he dropped hir limp, twitching body to the ground, pulling up his pants and striding away with a self-satisfied chuckle. "You earned that tip, good little cumdump. Have fun raising my kid, bitch!"
Lying there, Antonya tried to focus hir mind on something other than the intense orgasm, but shi couldn't help herself. Sobbing softly as shi felt another wave of pleasure crash over hir, shi cried out into hir gag, shaking and trembling as it took hir twice as long to come down from the massive orgasm as it normally did. Finally, with a deep sigh, Antonya fell limply to the ground, panting softly as she laid on the sidewalk, exhaustion overtaking hir, and shi passed out where shi laid.
