Previously, the set up from the other branch...
As you walked through the forest you slowly began to hear the voices of other people. Not wanting to be seen, you crouch down and moving slowly, you move forward, still making some noise as you walk towards the noise.
There were two voices. One female and one male. Slowly the voices grow closer and you eventually see two hikers emerge from a path. They were teenagers about your age, one was a tall brown haired guy who had his arm around a shorter blond female. You didn't recognize them, though you feel as if you might've of seen them occasionally at school.
Suddenly an idea pops into your mind and you grab the Book Of Myths from you satchel and begin to choose what spell to cast on them.
You open the Book of Myths and, pointing a finger at the male, you whisper the word "Shift".
The two were still talking when the transformation began.
"Yeah, we should go meet up with Jake after-"
Suddenly the male lurched forward and nearly collapsed on the ground. The girl instantly panicked and started trying to calm the guy down.
NEW STORY PATH BEGINS...
"What am I doing, wearing such odd and confining garments?" the guy asks, puzzled, then begins to undress in front of his girlfriend.
"Umm..." she begins, wondering what to say when she notices the changes taking place.
With him now totally nude, she can see brown fur has begun spreading all across the lower half of her boyfriend's body even as his legs twist around, the knees somehow reversing themselves as the feet merge into cloven hooves.
The guy is still moaning, but now in pleasure and not pain, as she notices his penis grow to twice its normal size flaccid and become encased in a brown furry sheath.
As he stands up for the first time on his new legs, she notices a short tail begin to form over his rump as two small horns appear on his forehead.
"By Pan, I feel great!" he proclaims, stretching to get the kinks out of his new form, even as his cock begins to become quite erect, its head starting to pop out of its new sheath.
"What... are... you..." she asks, even as she begins to back away from him.
"Me?" he asks in return, while staring at his girlfriend with lust in his eyes. "I'm a satyr, and you're mine you luscious nymph!"
Frightened, she turns to flee, but he grabs her before she can get away.
Scared, she starts pounding on his chest, begging and pleading with him not to do what he is about to, even as the newly born satyr struggles to get the girl out of her clothes and down on the ground.
"No!" she cries, even as he spreads her legs open and inserts his now massive satyr cock into her wet folds.
But while she was unwilling at first, as he fills her and continues fucking, her attitude changes. Between the super charged male pheromones he is emitting and the massive amount of pleasure she is receiving, she wraps her arms and legs around him and begs for more.
You are about to uncast the spell and leave the couple so they can have their fun in peace when you notice something you didn't expect.
SHE is starting to transform!
What you can see of her breasts shows they are growing in size, even as the satyr continues fucking her in route to yet another orgasm for both of them, after having already filled her with hot male cum once.
SHE IS BECOMING...
