Dear-ole-dad walked into that room of a devious daughter and with her then a son caught, held in a trance of obeying mindset to a Satyress sister. As what dad saw first was his son kneeling and with his face compressed into the crotch of his sister. In that same disturbing instant he also noted the form of a female, a voluptuous erotic form there seemingly enjoying the oral debauchery being done to her.
"What in hell is going on in here, Timothy!" Said the dad to his son.
Tim ceased from his oral play and turned to cast a by then rectangle shaped pupil, of his bright chrome-yellow eye to give a look back at a very surprised man. The infecting virus was made quick to cause changes when the trading of bodily fluids entered the mouth. As Tim ceased his tonguing of Linda, he facing there his father, showed a goatish sort of furred muzzle replacing what was his human shape of mouth and nose. In fact and essence the whole face on time looked of change to becoming the head of a goat soon. His ears too had accepted the transition, they broad, flat, as hanging down along the furry sides of his head. The stunned stare of his father made Tim want to laugh, but from the vaginal slime of his infecting Satyress sister, the massive changing began to become then giving of sharp pains about his forehead.
"Ow...baa...!" Tim expounding said as a half furred hand reached up to touch at his paining forehead.
As what Tim was feeling and felt of, his fingers touched the harsh points to a pair of goat horns protruding then his scalp. A second more of growth and further protrusion of the horns and a trickling of his blood ran down across his furry face.
In the meanwhile an angered new Satyress stood there giving her worst ever stare at a man daring to intrude on her being pleasured.
It began for dad then when the stare of his Satyress daughter met his stunned eyes, the connection of evil mind to the horror filled mind of a common man took hold and laid on him a sudden undeniable controlling.
Dear-ole-dad stumbled as tumbled to the floor, he fainted, blacked out, laid there helpless before a then aggressive changed daughter.
"Wait there my cute buck, remain kneeling while I give this foolish man his first taste to what you were so nicely pleasuring." Linda said, as she strode on her goaty legs to stand then over her father.
Three long fingers then she dug into her excited and weeping pussy. A stirring of the fingers gathered to them a goop of vaginal slime. Linda knelt slightly, she reaching her fingers coated to smear the slime about the lips on dad, and around his closed eyes, as coating the eyelids, and finishing her infecting of him by tainting his ears with her slick slime.
Almost instantly the infection took hold and the eyelids of dear-ole-dad became fur covered.
Linda strode back to where she was standing and stood with her furry legs spread slightly, as she looked down to see an obedient brother looking up at her. "OK there my cute buck, return please to how you were pleasuring me!" Linda said.
Unseen and quite unbeknown even by father, but the college age elder brother Kyle was standing then there just outside in the hallway and had seen his father faint. Kyle peered into the room through the crack of space between the open door and the door-frame. What he saw seemed to not bother him so that his father had fainted, but of what he saw was his sister, and how she looked to him as something he would like to fool with!
Kyle stood there for several long minutes, he watching his younger brother continuing to orally pleasure his Satyr-sister. He like was Tim then both brothers were sporting erections, though Tim had striped naked, was showing forth his furry self.
"Breakfast is almost ready to come out the oven," Mom called to her family, the sweet scent of baking cinnamon rolls was as much a call to come and enjoy.
Maybe of fifteen minutes watching, Kyle was witness to his brother Tim changing mostly to look like a sandy brown furred buck goat. He was bleating as Linda helped him to masturbate his by then very goaty shaped an erection. Kyle stood marveling the bright red cock his brother had then, it much longer, pencil thin, the circumcision replaced by a pointy end, looked to Kyle as something morbidly beast-like.
"BAA...," Tim cried out as his orgasm evacuated from his swelled testicles the last amount of human semen those two baseball side orbs would ever produce.
