The boy was still on his back after he came and lost his member in favor of a slick pussy in between his legs.
After the hormonal shock that he received he passed out for a God few seconds.
When he awoke he was very aroused and until he rember what happened he got a second shock as he looked where his cock once was before coming back to his senses and saying.
O, it's happening, I'm finally turning into a mare,he said as he cupped his brand new pussy with his hands.
I'm not a male anymore he said.
No you are not!
As he said this the stallion removed his charcoal black hoof from his navel and let him rise.
He went to theare and observed her while saying: I will be like you shortly.
As he looked under the mare he touched at her smooth belly that under in an equine pussy between her legs.
This trailing sent shivers up his spine as he cupped his own pussy.
I'm closer to being a mare like you then I've ever been in my life.
Just as he said this he saw another stallioneave one of the stalls and approach her from behind.
He dropped on the back of the mare he was just patting and the stallion's cock entered the mare on its first try. It secured her with his front legs and started pumping herself into her.
Do you see what you have signed up for boy? The mare was one of your male friends while the stallion is actually the girl you came here before you ran away to the car for your phone.
While looking at the 2 horses breathing he was the horniest that he had ever been in his life. He stumbled backwards and fell down with his back prompted on one of the stall gates while looking at them. He was so horny he wanted to jack off however he didn't know how to anymore so he settles for cupping his pussy and imagining what the mare must be feeling.
Admire her said the black stallion, revere how her every need is being fulfilled by her mate.
She is so beautiful, the boy said as he looked at her from head to hoof, I want to be like her.
I shall give you her beautiful hooves and legs now.
Yes, make my arms another set of legs, I beg of you, I want to live down on all fours, and have males see my eager pussy on display!
As he said this he watched as his legs started elongating and 2 of hie 5 fingers merged and shrunk down into his extended feet.The sould of his feet were lengthening and his remaining tous molded together to form his pasterns and then his hooves as his nails grew into a callous of keratin that eventually turned into back hooves.
His back legs were oversized for the rest of his body however that soon changed.
He had figured out how to play with his pussy hh now however when his hands started to lengthen into his forelegs he tried to stand up and he succeeded awkwardly.
His hands continued to lengthen while his palms lost their thumbs and pinky fingers
As he flexed his 3 remaining fingers he saw their skin melding together and after a while he felt hot they stiffened and became one bone on both of his forelegs essentially creating his pasterns.
At that moment while he was on he saw the stallion huffing behind his neck while feeling his presence and somehow knowing what he wanted.
As his fingernails grew into callouses of keratin he felt his forelegs studying up and bulking up with more muscles as if preparing to bear the mass of another horse.
His spine lengthened and his belly became much more rounded while his pussy became slightly larger on the outside and the inside.
At that moment the black stallion jumped on his back placing his whole weight just beneath his shoulders with his member swinging in between his legs just behind him.
The mareified boy was now struggling to keep his 2 legged stance as he felt the stallion was increasingly pushing more of his weight forward threatening to knock him over.
You are almost ready boy, however before I start pushing on one side to extend your neck and form your equine muzzle on the other I ought to ask you, (he said as he shifted on his hooves from on to side with his member threatening his pussy) As he did this the mareified boy looked behind him at the imposing stallion on his back securing him in place : Would you like to be broken in by your former girlfriend or by me?
At that thought he looked towards his former girlfriend now stallion and said: Oh Sarah, I have to confess that the first time we had sex I thought of you as a mare under me.
I know Paul, however your fantasy has been turned onto its head now, hasn't it?
Paul looked surprised at Sarah who could talk and said: As you can see I'm no stallion this time, you are!
Huh, said Sarah, I guess now it's your turn to be the one with your legs open in my fantasy, however I shall havey time with you Paul, said Sarah, Again and Again and Again until you swell. Out of courtesy you should enjoy the black stallion properly breaking you into the heard.
Paul nodded and said: You my black stallion are my choice, teach my my new place in life with that cock of yours.
At that precise moment the stallion pushed his weight forward and you could only catch yourself with your forehooves with a loud "clop".
Then Paul felt the black stallion push himself into his pussy while grunting and trembling.
Yes, yes finally!
Once he was fully in he was gasping and he saw Sarah at his head while saying:
Remember Paul, remember our first night?
Yes, yes I do pant pant pant.....
You are now the one on the receiving end.
I am I am Yes.
As the stallion started pumping and biting his mane his neck started to lengthen and grow a beautiful mane while his head started elongating into a muzzle and his nose flaring to take in more air.
His ears moved to the side of his head and lengthened as the stallion continued to pump. Each thrust lengthening his face and being in tune with them.
As his face lengthened and his teeth clattered down and out of his mouth while new teeth grew j their stayed that could only munch grass.
His talking started to sound increasingly like wheezing and then neighing of a mare being fucked.
Do you feel it now Paul? Asked Sarah.
Do you feel now how it is to be the one with your legs open?
Yesssssssssseeeeee Whezzing wheezing Nickering and Whening......... Wheeeee
His first orgasm as the stallion rocked his back and forth.
Sarah started to imagine how she will make him cum like this everyday and he would take it from now on and for the rest of his life as his pussy was now permanent. Their relationship was now perfect.
She iled as her muzzle was very close to Paul as the stallion cummed and gave the new mare another orgasm that rocked her world as she said: Just wait until I do this to you 3 times a day.
The mare was kept on the edge and fucked dun till her back legs ware trembling while Sarah was watching and enjoying his former boyfriends wheniying and orgasms now as mare with the proper equipment of one.
