What are you doing to me?
Turning your useless cock into something you can actually reproduce with given your persuasion.
I'm giving you what you want. Now you will be able to sit in between my legs without anything being off-putting for me or for you.
Ahhhh It's burning. Said Mark as he grabbed his cock which was extremely aroused and hot.
Let go already. You already proved you're not worthy of having a cock by trying to get under me,might as well accept your new position under me bitch.
As soon as he removed his hands the stallion lowered himself slightly and pressed his cock in between his and his balls.
Whoa what are you doing?
Fucking my mare,obviously.
Wait I'm a man, you can't just do that to me!
What man? Being a man implies having a cock, and the only cock around here is mine!
At that moment the stallion squeezed him in between his forelegs and started pushing like an animal.
It shouldn't have been impossible for him to advance anywhere, but slowly his member advanced deeper into his basin, his own cock and balls were dragged by the retreating flesh and into the opening he was creating. The boy screamed as he orgasmed with his dick parallel to the stallion as it was squeezed inside of him.
The stallion advanced deeper as his cock and balls were pushed inside him leaving no trace of them. The skin around the stallion's cock split and started taking the shape of a vulva.As the boy realized the stallion was inside of him where his cock should have been he passed out.
There you go, now you don't have to pretend you are a man anymore. Huh! He passed out. I guess getting fucked for the first time really took it out of him.
The boy gasped several minutes later and inspected his surroundings.
He looked left and saw a black horse hoof.
He looked right and saw a black horse hoof.
He looked up and saw the black nuzzle of the horse on top of him.
Then he checked his belly.
As he ran his hands along his abdomen he could feel a swelling that ran from his belly button downwards in between his legs. It felt like half of a soda can beneath his abdomen. When he tried to push his fingers against it, it was rock hard. As he was running his hands along its length it twitched. He desperately ran his hands along its length and where his cock should have been, there was a soda can size cock that was going into him.
Good you finally found my cock.
I...... I... no longer have a cock....
Isn't this what you wanted? Now at least your body belongs where you put it.
Enough of this, I'm pent up and you are in no position to do anything besides learn fast.
As he said that the stallion drew backwards and started pumping slowly back and forward.
His head started going back and forth in rithm with him.
You're mine you understand. You will wear my coat so you remember that.
As he said that black fur started sprouting from his back, hands legs, and in no time he was covered in a fine coat of black hair.
He started trembling as pins and needle sensations were building inside his abdomen.
I can feel you clenching, I think your first orgasm is worthy of you getting gift.
The horse increased the rate of his thrusts until he started trembling like mad and moaning.
As he went to grab for his belly his hands started cramping as 2 of his fingers receded into his body and the athers created his fetlocks and hooves.
His forelegs were long enough that he had to extend them underneath him with his head to the grond and his pussy in the air.
You don't need your hands anymore, learn to ride my cock.
As he said that he shifted his position and was now pushing against his thrusts.
His legs were next as they lengthened into his hooks and back hooves.
His tail sprouted next which quickly sprouted a layer of black hair. He flicked the tail as side as to not obstruct his stallion.
His belly expanded out slightly but remained petite for a horse.
He was able to force his legs under him and stand on all fours for the first time.
The stallion quickly readjusted and secured the sides of the mare from her back.
You're learning! Time to learn how to take a stallion.
In that moment he saw his fantasies come true, it was like they were visions of this moment. He had a stallion on his back. That was snorting hot air on his neck and mane mane.
The realization that he was nothing but a mare in between his legs was enough to trigger another orgasm as he squeezed the stallion cock with the folds of his pussy.
He felt a torrent of heat rush through his insides as the stallion bit his mane and dragged him closer to him.
In that moment he whinnied and dragged his head backwards at his climax of pleasure. Nothing in his life had felt this good certainly not sex seeing how he just lost his virginity.
His neck elongated as his ears moved to the side of his head while his eyes repositioned themselves to give him a wider frame of view.
Thank you! he said as he raised his head to the stallion who lowered his as they kissed. His head elongated into that of a horse while his teeth and tongue became ferfect for a herbivore.
Madame Illusia then opened the stall while the dark stallion was dismounting the former boy.
He came out really nice. Make sure you keep his belly full, I need more hooves on the ground!
Yes ma'am.
The other stallions were looking at him intensely however he only had eyes for the one he had sneaked under.
After Madame left the mare was nipping at the mane of the black stallion clearly looking for more.
