{Just a non-Futa version}
John said no, the idea is intriguing, but I like my mares wanting my cock.
CERES – Cool, now on you go. I can’t stay here for too long.
John’s first goal was his grandma’s house, but on the way, he stayed near a park where two pregnant mothers were talking.
He sat across from them and watched as they became more and more beautiful.
The redhead on the left was the first to react, she stood up and removed her clothes while still talking.
The brunette followed suit, all the while they didn’t even notice their clothes disappearing from the ground.
The redhead, being the bustier of the two didn’t even have time to remove her bra before her expanding chest broke it, then came the leaks. Both started to leak a good amount of milk while their breasts grew into massive M cups, probably because of the milk actually. The thing is...their bodies weren't following, they were still the same height and the absurdly huge leaking breasts looked almost painful on their human bodies, so much so they both had to sit down back again. Fuck! their boobs were larger than their bellies, and their asses were starting to make the bench look small.
Soon after their asses grew to its final size they started masturbating furiously, and with each orgasm (which came in great number), they grew in size, finally making their bodies more proportional.
The redhead pussy’s started to darken and grown in size just as the brunette’s tail shot out of their behind, and then they change places.
Fur was next, along with hooves that came fast as both of them started drinking the other’s milk. The redhead’s fur was an orange colour, similar to her hair but not completely the same. The brunette’s fur was black with white spots all over.
Both of then neighed as the last orgasm rocked them, finishing their transformation. John was almost ready to burst himself.
CERES **in his head** - Did you like it? I enjoy changing things along, so they don’t get boring.
Indeed he enjoyed it, as did the two mares over there. As they were ready to leave, they noticed a stallion looking at them and came over.
REDHEAD – Hi there, I didn’t know there were more horse people around, and such a fine stallion to the booth!
BRUNETTE - Look at the size of his cock!
