Ann's form begins to change, but Todd and Bob are oblivious to this fact. Todd is single-mindedly pounding the nanny for all he is worth, the sexual drive preventing all other thoughts. Bob has his eyes close and hands cradeling his daughters head as she sucks his now hard cock. He too is to occupied to notice that the Anne is now returning to her girl self.
Her goatish figure slowly becomes hourglass as her formally thin waist and womanly butt begin to reassert themselves. Her nipples begin to recede and her ample breasts grow from her goat body. Even some of her own thought are returning, but these are still swamped by her goat side and the passion of the moment.
Glancing down, Bob notices his daughter's raven cascades of hair now grace the nanny sucking him off. His mind in a haze, however, he does not attempt to stop.
Anne's changes are now quickening. Her pert nose, almond eyes and facial features now grace the nanny. The muzzel retracts and human sounding groan of pleasure mixed with confusion are audible.
Now her hing legs are that of a very beautiful, healthy girl. She is now down on her front legs and human knees, meeting the thrusts of her goat brother and pleasuring her father.
Bob's cock feels the difference between the nanny's muzzle and the much more pleasant and arousing effects of a woman's mouth and tongue. Still, he is too wrapped up in his pleasure.
Now Anne is fully human, and her own intellect and person become dominant. At that moment Todd releases his load into the warm pussy of his stunningly beautiful sister. He bleats and she groans in pleasure as the cloads of confusion begin to break. She then feels a warm explosion in her mouth as Bob looses his load deep within her. She swallows and suddenly is fully cognicant.
She screams and pulls forwards, causing Todd to lose his grip on her ass with his forelegs and his cock to get pulled out. She stumbles to her feet. She stumbles backwards, trying to comprehend what has happened, looking at her father, a goat and then down at her naked, dripping body. Giving another scream, she runs to the bathroom and locks the door.
