Dan still wanted to expand his harem. The stallion ran down the street, shocking passers-by, before jumping the fence into the courtyard of a large modern house which belonged to the O'Brien family and their daughter Klareen, a fellow student. Klareen was his crush for many years and was the popular, perfect type of girl; D cup, an hourglass waist and sexy hips. Only the branches of American football could approach him and Dan wanted revenge.
She was reading in her room when she was startled by the sound of hooves and neighing in the courtyard. She went downstairs and out the back door to meet what was once Dan, even though she had no way of knowing that.
Needing relief for his straining balls and having already filled his mother earlier, Klaareen was the next logical partner in his now equine mind.
Stunned by the sight of a horse with balls the size of beach balls, Klaareen had no time to react when the stallion lunged at her and began tearing off her shirt with his large teeth, falling backwards, terrified and unable to act. Klaareen was easy prey, and her shorts and panties soon followed, leaving her naked and exposed to the stallion.
Finally, she got up and tried to run, but she was far too slow to outrun a horse, even slowed by such large bullets as he possessed. Flipping Klaareen over, Dan began to penetrate her, knocking the wind out of her and beginning to pound her.
She moaned as the huge girth inside her throbbed and filled her with seed. Such mating would normally have killed her, but the magical seed created from her aunt's remains strengthened her body, even as her belly began to expand.
She moaned, unable to move as the magic-infused cum began to change her.
Everything deformed from her hips to her breasts flattening into teats to her hands becoming hooves and a proud tail growing from her.
Then Klaareen's neck thickened and lengthened, leaving her as a full horse, except for her human head. She turned to look at Dan and, no longer able to contain herself, she moved her cock to the side, giving him a full view of her equine pussy. “Ride me, dammit! She panted, make me your mare, put a foal in me!”
As the words reached his ears, what little inhibition he had crumbled and he pushed himself up, landing on Klaareen's back, now able to support his weight. He delved with his enormous penis, before finding his mark and plunging inside. This mare would be his.
At the end of their mating, the last vestiges of humanity disappeared. She was going to have so many foals, Klaareen thought, just before her human mind faded away.... What could they do now....
Suddenly the sound of the lock was heard.
