About a minute into it, Jeff's flacid cock begins twitching as a sudden rush of pleasure assaults his body and his cum begins oozing out from the tip of his still flaccid cock. Not only that, but it happens again not even half a minute later as Emma continues going hard on her boyfriend's ass pussy.
"Yeah, keep on cumming like the sexy bitch you are" says Emma with a smirk as she gives Jeff a little bounce, causing yet another load of cum to ooze out of his cock. She also begins sucking on one of his nipples while Jeff can only squeal in blissful ecstacy.
A few minutes later, and both of them are laying down on the bed, both completely spent, yet thoroughly satisfied. They recover their stanima soon enough, and Jeff leaves, heading back home. He is very satisfied with the trial run, and has a few ideas about what to do next with the Chronivac.
Once back home, Jeff finds a dildo he must have missed earlier and sets it down on the desk chair, before mounting it. He begins using the Chronivac, all while gyrating his ass up and down along the shaft of the dildo. The first change he makes is altering all men to have pussies for assholes, and all girls to have cock instead of clits.
Jeff let's out yet another girly noon as he feels his new pussy moisten rapidly, fully eager to begin fucking the dildo inside of it properly. He also makes all men have feminine legs and feet too, since he has become envious of Emma's gorgeous, smooth and hairless legs.
Now, unless you inspect the crotch, men and women in this town look indistinguishable from each other. It is now very hard to determine someone's gender with a glance. Unless of course they are rocking a hard on, showing off either a pair of balls, or a camel toe.
Jeff moans lustfully once again, as he climaxes, and now cums directly with his new pussy. Drunk with lust, Jeff makes a change that if a man's pussy is impregnated, he will always conceive twins, and will carry one in each ass cheek, as he now has a womb in each of them. And, while he is at it, he made women have bigger cock on average then men, while all men have a better pussy than a women's on average.
He even goes so far to make women often have animalistic cock shapes and sizes too. And then to compliment it, any man the woman claims will have their pussy adapt to become a more suitable one for her cock to fuck. So if she has a dog cock, her claimed man will have his pussy turn into a dog's pussy for her.
Jeff suddenly feels his pussy begin lengthening up his back, as the dildo inside of him pushes deeper into him as it takes a more equine shape and size, while also turning a more leathery black style and stretching down his ass crack a bit. He grunts as his new mare cunt takes in the full shaft of the dildo inside of it.
Jeff clenches down on the shaft and stands up, taking the dildo with him, as he discovered the base of which has now become a sort of plug, which now is stuck inbetween his pussy lips. He gives his ass a quick shake, confirming that the plug is definitely secure, before sitting back down, properly this time.
Finally, Jeff makes himself now share a home with Emma. The room quickly changes and Jeff finds himself back inside Emma's room, only Emma is clearly using the shower from what it sounds like. The dildo plug in his pussy now also has a tail resembling a horses attached to it too, as several pieces of horse equipment lay about the room. Things like mouth bits and harnesses, as well as a few different styles of pony boots, including a pair that actually has fake hooves. Even he finds that, due to now living with Emma, he has also become the owner of his own sets of all this fetish gear too. And that his feet already are inside one of the crazy boots, and is being forced to walk and stand on only his tip toes. They are uncomfortable, even mildly painful. So he changes his body to be able to wear them easily for days on end if he had to, and with no issues whatsoever. This change is then extended to everyone who this change can benefit as well before turning off the Chronivac.
Jeff then slowly walks over to the full length mirror, all the while exaggeratingly swaying his hips with every step. He strikes a plethora of stunningly seductive poses. Some of which are even more sexy than what he was initially intending for them to be. He also notices how his ass is bent upwards, as his back is much more arched than a normal human's back should usually be. And yet he feels fine. He has a literal shelf for an ass too, and from the looks of it, his upper body almost looks as if it is coming out from the front of his waist, and not above. It really is just him having a crazily flexible back bend though, and doing this gives him the appearance of having the entire ass of an actual mare, and not just the pussy of one.
It is now that Emma strides into the room, towel draped over what can only be described as a third leg poking out in front of her. Her stallion dick is already really hard and eager to please its compliment. And Jeff is is more than willing to comply.
