Jeff was giddy as he sat down in his chair again, shivering slightly as he was nude and his cunt was exposed to open air. But he wanted more.
The Chronovac could give him just that, a life swap between him and the mare, to see what it would be like in a rather strange fashion. After nearly ten minutes of editing and changing settings he was ready. For the next few months, his life would be the mare’s, and the mare’s would be his... along with several more changes and an intresting one he’d discovered on the mare’s profile.
Hitting enter Jeff closed his eyes. Giddy as the world around him changed. His hooves hit grass and when he opened his eyes again, he was standing in a field of grass, grazing horses all around as he smiled and spun on one hoof, waiting for the changes to physically begin.
The first was by his hips, a small popping alerted him to a shift in his bones, his ass starting to grow to a more bountiful size as tail grew above his expanding butt, forming a long black tail as his new ass jiggled, and bending slightly he moaned as his vagina repositioned into the normal place for a Horse’s.
Of course that bending had its own flaws as his enlarged hips cracked again, locking him in that bent position as his slightly bulkier legs held his weight. Jeff snorted as he took his hands off his knees and set them on the ground, feeling his arms bulking up slightly as his hands started to ball up and turn black.
Ignoring the formation of his new hooves, Jeff flicked his changed ears, having missed his human eyes vanishing for the horse ears atop his head. His chest starting to barrel out slightly as his nipples migrated down his chest towards his crotch, liquid starting to fill the sacs beneath his nipples as his new horse udders found their new home.
Jeff groaned as his neck grew longer, not extremely long, but long enough to graze as his more horselike body was wracked with pleasure. His younger lolled out of his mouth as it continued to grow in temperature.
The mare had been in heat.
And now, Jeff was the Mare, partially. He looked human in most respects, but he was seen as, and his history made it so, that he... she was a horse. Her scent wafting through the field as Jeff snorted in pleasure, begging for release.
