The drive to dominate began to take its toll on David as it had to Stella. Each in their own way felt greatly different and from the sensations came a desire and willingness to accept and want a life of bestial ways.
David thrust his might mushroom tipped shaft into Stella, making her groan with the wild passion she had never felt when being a human female.
Turns and twisting only made David want for more of the fantasy feelings, as if he were living a dream.
Dreaming turned to a nightmare when from what had found his donkey stud cock her joy, Stella did clamp down with mighty muscular strength, and took control of her stud.
Heavy breathing and abrupt panic took hold of David, he began to realize his dreamy delights came from profoundly real sexual sensation of two mature animals mating raw and rough.
When did his massive shaft fire that mighty load, it spewing out the opened end of his cock like the water cannon on a fire truck. The pasty globular goo stuck inside of Stella, doing his thing to her. The volume became a river of lust, filling even a massive donkey mare womb, spilling forth in a water fall of cum, semen, and varied juices.
Stella could do nothing more than tell of her sensation by giving her stud an affectionate soft tone Hee-Haw bray.
David had such a blend of satisfaction and horror he could do nothing, only falling off his jennet he stood and eyed a look at Henry.
"Raw brutal, and downright crude, but you cannot tell me that you do not love it; can you?" Henry chided David, he smiled at his newly formed stud Jack, seeing the tool that would win for him a fortune, and cost him only a mite of his special blended mixtures.
