Paige would agree she had become magnificent her change of species and gender, becoming partially a pony stallion.
Allison was becoming so horny from her ingesting orally the semen from Duke and then Paige, that having accepted vaginal mating once, her body began showing added enhancements. As both friends agreed to mate a second time, Gina stood nearby watching, she starring, seeing Allison s if having grown larger, her face elongated, nostrils broader, and lips as having thickened.
"Ugg," went Allison as Paige in one swift thrust slid inside her friend a pony cock similar of length and girth as is that of a born Shetland pony stallion.
Thrusting and rutting began as Paige his her best to gain the radical feelings of being male, a stallion mating a mare.
Allison stood there and felt a delight that somehow her vagina and womb was able to take the length and girth of the pony stallion shaft. She stood with an agape open mouth, saliva drizzling out it, as her rump swelled, her legs snapped while joints conformed, and her head became wholly equine of form.
"Nieghieeeeeeee...," screamed Allison when Paige in her heightened sexual form shot a mighty load of pony semen into the by then almost fully conformed mare.
"Allison," Gina screamed, as she seeing there Paige yelled then her name too, as both friends were changed more to resemble their pony forms than having anything to suggest they were ever human.
Paige had changed in her mind and attitudes, as after spewing in her semen load into Allison, she stood off, pulled her cock out of the almost mare, but giving Allison a sniff, Paige mounted her again for round three and a complete damning of her friend to being a pony mare.
