Tyler stood there listening, he hearing from some unholy black cloud a voice informing him of to what his bodily self shall become; and all decided by what Courtney had allured him to do. He had some personal pride, and mulling the ideals of an unholy spirit and what an Anthro-Mule seemingly liked the idea of was not his plan of future endeavors.
"No, not me," yelled then Tyler, "No changing me to becoming as female, whether womanly or as some ugly Molly Mule. I like my being me, and not what you two would wish for me to being!"
"Ha boy, you have no choice now of what shall become for you a changed sensual future. You orally took from Miss Courtney her given semen and ingesting of it comes with bodily changing properties. As you become a female, your' mindset shall learn to relish being that of a female; endeavoring to feel the sensations of a Molly Mule animal. Consider the differing aspects of not fucking but of being fucked, as colloquially expressed in your slang style lingo!
When being female, and as is a four legged Mule animal, the size of your vulva, vagina, and womb that can accept equine cocks; they ten times the girth and length of male human penises. Consider..." the Tome spirit lecturing to Tyler while enthusing Courtney to sporting a stiffened erection.
"Still no, because I like my being as male; I'll not take part in any second fucking with me. As yes Courtney, your semen tastes heavenly, as well creamy its texture, and held me feeling willing to accept any of or how; but in considering the aspects described, I do not what to be either as female of a Mule' animal.
I shall take my leave of you, as you Courtney being this Anthropic form of part human and having become lustily a..., ah, ah, male Mule...
No, I shall not be enticed, I am as I like being, and becoming an animal, a Mule and made worse as then female is not what I want!
You stay away from me..., that cock, its tasty, the sullen bulk of it felt so nice when pressed through my mouth to lodged in the far back of my throat..., NO, not again; what my doing of it all again would doom me to being for you..., ah-as, no, no, no...!" Tyler exclaiming, as becoming excited from seeing Courtney sporting his then stout erect mule size cock.
"No matter now boy, but what was done has begun showing the coming changes you must endure. Look down at your navel, as see the darkening hue of Mule hide and body fur beginning to spread outward, as shall gift you the pelt of dark brown body fur, and soon too a mane and black tail. I see your penis as dwindling, your scrotum doing so too, and your nose is beginning its merger with the mouth to forming a proper muzzle. Do you feel it beginning, as with an oops and your penis is now a equine twat, in part of your vulva!
You can't just leave and return home, as what you are by then, your dear mother, she most assuredly could not recognize as being of her flesh. Ah, just look at your chest as womanly breasts are now forming, nice big nipples, they black of skin color but exact in texture; something for a short while that you shall like to message and arouse your lusty sense of feminine passions.
Hey, and nice furry as point ears, Mule ears, and given time, they shall with the reconfiguring of the head shall migrate up top.
Wow, Tyler, your breasts are blooming, you could get a temporary job working at Hooters; but they hire women, and would disown you when becoming an Anthropic Mule waiter! The Tome spirit talking, it chiding Tyler as his body was knowing of changes.
"No, no, Neighee-Hee-Haw," screamed Tyler, as he hearing his voice changed, did turn away and ran for the apartment door, did turn the nob with a fuzzy hand. "Naw-haw," exclaimed Tyler, he seeing his furred arm and fuzzy brown hand, knew he was naked, but wanted of nothing more to do with Courtney or that eerie voice from a black cloud.
A slamming closed of the apartment door bade Courtney to give a sad Mule's expression toward the black cloud. As with both ears laid flat as back against the equine skull, Courtney stood wide eyed with muzzle agape.
"Worry none for Tyler, as what he shall become and being an Anthropic woman Mule, his prospects of living a full life shall know disappointments. Mostly her cursed aura that similar to yours shall allure young males to want for their mating of her, and she, her vagina extruding infectious juices, shall create for her lovers Mule size, long, as quite uncircumcised formed cocks, a handy sheath, and donkey size testicles. They then feeling of rouge urges shall seek male pleasures by mating with pony mares, donkey jennets, and drunken women.
Tyler shall by midnight be panging for some stout cock to ease her new passions. As time and lust shall allure him to seeking you and wanting what you can complete for her. If you wish it, I can hurry along your physical transitions, and assure you that when Rene arrives, she shall see then new you; the equal of a two-year-old john Mule; but with your mentality, intelligence, and memories as fully intact!" As what the cloud spirit offered had Courtney nodding, she urgent to become as is a john Mule.
