All three girls run over to Kyle, their donkey parts quivering with need. Kyle smiles, and wills them to change further. Felicia falls to her knees first. Her donkey cock shakes up and down, and occasionally hits the floor. She brays as her face pushes out into a muzzle. Fur spreads across her skin, and her hands and feet lose their form. Her ears tug upwards, and a long tail shoots from her tailbone. Long wiry hairs sprout from the end, and similar hairs cover her sheath.
Felicia's hands ball up, the nails growing until they encase her stubby limbs in hard, black keratin. Her feet do the same, stretching out as her nails merge into one large black nail. Soon she's on all fours, a complete donkey with two large balls and one leaking donkey cock.
Meanwhile Jen and Sam are having a similar transformation. Their faces turn to donkey snouts, and their hips crack forcing them onto all fours. Donkey tails swish back and forth, barely covering their engorged pussies. Their lips get even doughier, and move back until they're directly under their assholes. Breasts shrink and move inbetween their back legs. Jen brays softly, as she feels fur continue to blossom from her body. Sam's mane sprouts before the other girls' do, and she shakes her head. Their ears can almost hear the sperm churning inside Felicia and Kyle's ballsacks.
Kyle stands ready behind her, and drives his cock home. Sam brays loudly, and thrusts her ass backwards. Felicia and Jen, no longer able to contain themselves, do the same. Felicia mounts Jen, sliding her own hairy cock into Jen's folds. Jen moves her head forward to sniff Kyle's enhanced asshole. She runs her tongue over it, and Kyle moans in pleasure.
"Go on, do." he said. Jen sticks her tongue into his gaping hole. Kyle starts pounding Sam, and Felicia starts pounding Jen. Sam wickers and sprays urine all over the floor. The smell drives both Kyle and Felicia crazy. Their humping becomes sporadic, and soon they cum. Kyle's head and balls become tense before spewing his hot seed into Sam's equally hot cunt.
Sam's and Jen's brays fill the room, while Felicia snorts as her load finishes. But they're far from done. As soon as Kyle finishes with Sam, he turns around to face Jen. And then inserts his cock into her mouth. Feeling her tongue lap at his dick is better than when she was eating his ass out. Sam, not wanting to be left out, looks to Felicia. The two donkeys snort at each other before Felicia mounts Sam once more. The head of her penis teases Sam's folds, brushing against the outer lips.
Impatient, Sam nips Felicia's ear. And then Felicia rams into Sam's asshole. Sam almost screams as her tight ass is filled with donkey cock. Jen's pussy clenches, dripping fluid onto the floor as her tongue runs over Kyle's dick. Her tongue slides into the slit, and Kyle bucks his hips as he cums. Felicia's balls pull up and she releases another load.
The two female donkeys are left exhausted, and breathing very heavily.
