As the rush of passion in brother and sister slowly subsided, it was Todd being part male goat of body and mostly a rowdy buck goat mentally who had just infected his older sister. He sighed as he felt a small bit of male satisfaction, goat buck style delights had thrilled him, and he to her left his sister lying there in awe.
"Annie...," Todd moaned, his buck goat cock softening, it sliding out of his sister and back up as moving inside his furred sheath.
"Todd, what you did to me..., I think I love what you did to me. Look at you, and I look at me, shall I get to be as much like a goat as are you?" Ann asked, she swooning still from her deflowering experience.
"I think so..., please forgive my abruptness, it is what a buck goat feels and needing, must follow his urges. My want for mating, for sexual copulation, fornication, I saw your body and felt such desire to dominate it. I asked for this!
Yes Sis, I went to Pleasure Island Park and there met a real witch. Her name is Madame Illusia, and she put a spell on me that changed me to look like a Greek satyr. Her spell is more like a curse upon me, my wishes for wanting sex with girls is now an overpowering need I cannot deny. I wanted to look like a satyr and get to do what such animal-men did in stories of myths.
It, my curse is moving me onward, I can feel it working inside me, changing my guts, making me more like a bovine, cud chewing beast.
I giggle at the thought of you and how after we had sex, you too shall begin feeling and seeing your body changing, becoming akin to that of a doe goat. I suspect, as early on, our infatuations with sexual pleasures and pleasuring us and others, will keep us from realizing just how much we are becoming goat-like.
Something in my mind is suggesting to me to be careful and not give wholly in to my male animal lusty desires. As if I become so horny that when seeing smelling, of a real born doe goat, I would begin mating with animals, my satyr self will change me fully into a buck goat; and that I do not wish to become!" Todd said as to explain to his sister what he felt and knew about being a satyr.
"Wow Todd, what you tell is like a fairy story but after what we just did I cannot deny what my brother is, and what I wish for joining him, we being satyrs together.
If my memories serve me still, only men were or became satyrs, not women. So how and why am I looking more like a satyr?
Just look at me, as I am growing horns, my body is growing fur, my groin tingles wishing for your big cock to stimulate me again and again.
If you had come to me and asked me to join with you earlier, I would have slapped your face and tried to hurt you. Yet now, now I feel a greater sense of mutual desire, similar I would imagine to how goats feel lust for their own.
Something in my mind is telling me that, the more we mate, have sex, enjoy sex, the more I will change, changing until I have an udder, teats, and stand bleating like a horny goat." Ann said, she telling her changing brother how she felt and knew their lust for each the other would doom as damn their futures.
Suddenly, they heard from the other end of the house, a door being opened and their mom calling out to her children, "Hey kids, we are home!"
"Mom and Dad are home, what do we do?" Asked Ann of her brother.
Todd grinned, and he looking around where he laid, then rose up to stand on his new goat legs, goaty cloven hoofs, his goat tail wiggling with lusty glee.
"I shall go after Mom, and you corner then Dad, OK?" Todd suggesting said to Ann.
Mom and Dad were bringing in from the car the week of groceries, and doing the unbagging of the items, they like usual were putting the stuff into the kitchen cupboards.
"You are kidding?" Ann asked of Todd.
"No, and I am in no-way a kid but a buck and more like a horny one!" Todd said, as he reached a hairier hand down to help lift his sister to standing. "You with me?" Todd asked.
"We are by your spell, that curse, has changed us, and made us to look as do like goats do. This is not right, even if I cannot deny it feels neat. To infect Mom and Dad, no I do not wish this for them..., ack, gak, aw...!" Ann said, she had turned away from looking at her brother, she thinking about the love she held for her dear mother and a father who was as a real Dad. It was as she turned to face again Todd, that he put his hands onto her shoulders and shoving, pushed her to kneel before him. Tood then, quickly as might a buck goat had his cock out in a fully erect state and with his gaining physical strength, he did thrust his cock into the mouth of his sister, feeling her warm, moist mouth, Todd ejaculated a mighty load.
Ann knelt there choking, forced to swallow the three long ropes of goat semen coming from Todd and his by then, Kiwi fruit size balls.
"You will do everything I tell you to do, swallow it down and become for me as more than a sister, I need a follower!" Todd said.
