...realized he had to fix this!
Jesse was still nuzzling at him as he stood up, stumbling on his clumsy hooves, tail flicking. She practically filled the dorm room and she leaned against him, sending him tripping slightly. He caught himself on the desk and leaned forward over the laptop. He frantically looked through the options arrayed before him as Jesse's muzzle shoved him in the back, aggressively nuzzling him.
Her profile, Jesse Ronstead now showed her as a 100% American Thoroughbred mare, with her mind inside. But the sliders under her mind showed that her libido dominance and sexual aggression had spiked slightly due to the exposure to his musk and cum. With no saved profile for Jesse he couldn't revert her! He could revert himself though, as soon as he fixed Jesse.
He started to recreate her from memory, then pulled up a Facebook photo. It wouldnt' be exactly right but it would be close. As he adjusted her body fat percentage down, guessing based on a photo Jesse bumped him with her muzzle and his arm jerked, clicking several options at once and triggering a change. Jake gasped, reading - "Percent Human -95%, Dominance -100%, Libido - 90%, Body Fat - 5%", Height, 6'6", Aware - Yes".
Jake turned slowly back towards Jesse and swallowed. While the Chronivac worked there was nothing else he could do but watch as the enormous mare in his room started to shrink and change once more. She reared back and whinnied, her barrel like torso shrinking and compressing. The hooves at the ends of her limbs split and her legs scrunched and flexed, filling out with hard muscle and tan skin once more, although somewhat hairier than she had been. Her muzzle pulled back into a face, almost human other than its flicking ears and broad flat nose. And the dark brown eyes that fixed on him.
Jake scrambled backward and bumped against the desk as Jesse stepped towards him. Her hand reached out, on a arm of rippling muscle, and grabbed him by the throat, eliciting a chocked gurgle. "You little bitch." Her voice was deeper, in her amazonian form. "You fucking changed me. Into some horse! With this shit?" She glanced down at the Chronivac and slowly smiled. Her changes were still completing, her chest swelling back to size, although with her low fat percentage and muscular development they were still quite small. She had a practical forest of dark pubes as well and musky dark lips.
"Well now I guess I'm in charge, huh Jakey?" She grinned and with the single hand at his throat forced him down to his knees and then kicked him in the shoulder. Jake's vision flashed and he felt something break, causing him to fall to the floor in front of the desk. Jesse stepped over him, and humming, went to work on the Chronivac.
"First things first, time to fix this mess you've made..." Jesse said, clicking through her profile. Jake, shoulder throbbing, knew he only had one real chance and he...
