When Bob stepped up to standing on the bale of hay, he was at the same height to the horny mare as would the stallion he had originally planned to use to breed with the mare. Her scent was driving him near insane, as had his frolic he had so enjoyed with a now satyr shapely wife. He suspected she had infected him because his maleness had grown larger, hung longer, and down deep in his soul he lusted to be as mating with the horny mare.
"No, no this is wrong, what am I doing...,"Bob cried aloud, even as he held his erect cock and pointed it for an entry inside those winking lips of equine sex.
Wrong and immoral, neither reason was enough to sway his sense of determination; he was going to mate, have vaginal sex with that mare!
As not his penis but becoming similar of shape and contour to an equine horse cock, his shaft touched the winking lips. His touch ceased her winking of those lips, and as the cock slid inside her, stout vaginal muscles clamped down, grabbing at Bob, sending him into a level of bestial desire he never thought of as possible for a man. Bob screamed for joy as he enjoyed linking with the mare.
Meanwhile, a duck tape bound satyr wife knelt at an upstairs bedroom window, she watching, horrified and angry, seeing Bob finding that mare as equally enjoyable as he had with her. "Go ahead, you fool, as my satyr infecting of you has no bounds of how to infect and cause a body to know drastic change. Huh, I should know what if feels like to be so transformed, me my body changed into a sex crazed half human, half animal creature.
Yes, yes do her, stick your tainted cock inside the mare and enhance your infection while infecting the mare with a mind melding, she gaining a portion of what all you learned and know. Beware my sex-minded husband, you are damning you body and soon your soul to being more as is an animal than you are a man!"
Bob would later agree with what his dear wife said, as she would curse him to discover what it felt to be both a human male, while endowed sexually, physically, with equine genitals. As Bob hung onto the rounded, muscular rump of the mare, he was thrusting as best he could, shoving his enhancing cock deeper, as sensually arousing her and him, both knowing the delights felt from an equine style romp of fornicating.
Seventeen mighty thrusts was what brought Bob to his climax, his swelled bigger balls firing not a quick spurt of semen, but four mighty felt ropes of equine volume he ejaculated inside the mare. "Ah..., ah..., ah, ah..., by all that is holy, did I just do what I think just happened," Bob said as after his semen streams quelled his sense of bestial adventuring, he felt ashamed, though sated.
As Bob went to step off the hay bale, he forgot about his work jeans piled about his feet, and he stumbled, to falling off the bale, leading to his seeing a satyr wife gawking at him from inside their bedroom.
"You, damn you my dear wife, but your infatuation with all forms of sex and sexual debauchery, you have infected me with being a satyr!" Bob yelled up at his wife. His angered yell disturbed the mare, she struggling then to get free from the steel apparatus what held her as helpless for the sexual advances of any horny stud.
First came sex and then anger, as two intense emotions worked to redirect the already infectious nature of how Bob, his maleness was changing, becoming similar a satyr, he since added the doom of bestiality as a sin. Sins beget more sinning, and although he knew this fact, having mated with an actual satyr female, his wife, Bob realized his future was fatefully changing.
A harsh scramble to be free from what had entangled his feet, causing him to fall, and Bob kicked away his jeans, his shoes went next, and then in anger about what he had done, he peeled off his wool socks. Infuriated with his wife, a half naked man stomped from the barn to what was his house, and there his wife.
When Bob swung open the bedroom door, his horny dear wife burst out in laughter.
