Rons Mind goes fuzzy from the kiss. In an almost hypnotic state his left hand reaches to stroke himself and he starts jacking off slowly. Rons dick is getting bigger and so are his balls. His mind is getting more and more clouded with every stroke. He reaches his right hand and uses two to pleasure himself. The lady has now backed off. She is sitting a few feet away watching the changes as she fingers herself.
Rons ass grows bigger and a nub forms at the end of it. The nub grows long hair that forms a horse tail. Rons balls grow darker, almost black, while his dick becomes distorted and flat at the end.
The lady is now completely naked, her c cups hanging in the air. One of her hands is still rubbing her clit, while the other is groping one of her brests. She is moaning softly to herself thinking about letting that beast fuck her. The more she thinks about that the hotter she gets.
Rons legs have morphed into the strong legs of a stallion and his feet have turned into hooves. He is still stroking his cock, maybe a little faster now, his cock is now that of a large stallion and has the sheath to go with it. The tips of Rons fingers are black now.
