The breeze worked to wafting the aroused scents of two stallions, letting their lovely mounts, the two mares to sniff and renew their sense of female arousal. Snorting, the two mares became nervous, tails flicking, their vulva winking, some hoof stomping, and craning of horse heads to gawk at John and Ken.
John having had retained more of what he was when a stallion, the aroused pair of mares worked on his senses, making him lick his lips with thoughts of again tasting either mare.
"John, John, be careful my friend, once a stallion can be for fun or just humiliation, but go for round two, and you being still more as an equine, Anna might ave a trip, a trick set, and mating with the mares a second or third time could, leave you permanently being a stallion; either as a horse or a pony." Ken suggested, as John would have ignored the warning, he began walking, returning to then breed with either of the mares.
Ken grabbed at and held firm to the upper left arm of his friend. "No, now think, turn off that wonderful sex drive, and use your mind to reason, not your big balls!"
John stopped, and then turned suddenly to facing Ken, as each, their arouse pony size cocks then bumped, sending a strange wave of highly changed sexual depraved lust, as one stud for wanting the other as a mate.
Like swords, the two friends let their erect cocks slide at and across the other, whipping up sensual desires, but none for the mares.
"S-t-o-p-..., as I am not gay...," moaned Ken.
"Me neither, but why when our cocks touch as they are, do I feel an urgent need to ram my cock up your ass?" John asked of Ken, they sword fighting with their erect cocks, each being sixteen inches of excited male meat.
"What then of just one short fucking frolicking with my mare? Might that hurt my chances of becoming wholly human; as or doing it to you...?" John asked, his tone changing to one of trying to seducing Ken to lean forward, and let then John have some fun.
Ken began backing away from how John was approaching. Both friends seemed to have ideas about the mares, as Ken wanted to saddle up his mare and ride for civilization. John became more aggressive the closer he came to being near his mare. He stared at Ken, trying hard to gain a direct eye contact, as if he knew how to create a magical spell.
Ken tried hard not to look directly at John, but kept pushing him away, flagging his arms, as he did, his right hand and arm he stuck into the winking vulva of his mare and mount.
"Wham," and strong equine mare vaginal muscles clamped down hard to hold then what felt to her as an invading cock.
"No, no, oh John, what have I done now..." Ken yelled, as from where his arm had entered the mare, it began to show a return to being a foreleg.
