Upstairs, Alex had finally climaxed inside Lucy and was now basking in the afterglow. Despite his canine appearance, he was not stuck to his partner like a normal dog, but also had no wish to leave her warm insides any sooner than her had to. From the other side of the door, Kate watched in what was happening. She didn't yet found the strength to enter the room. She felt a burning jealousy of Alex, parts of her felt like she should fight for his mate. However her motherly instincts would win the fight this time, powered by the shame she felt for her previous hostile behavior. She was his mother first and foremost, and she would not allow this instincts to overpower her again.
There were other instincts however that would. Her penis had once again broken her pants and was set free and it would no be denied. She twisted the doorknob and entered the full view of both members of the family. A part of her was worried Alex would be hostile like she was, and at his current size he could easily hurt her badly. Shockingly, Alex approached his mother calmly and ripped her clothes off before starting to lick her breasts. Semen sprayed on his chest as she orgasmed but he did not care, he had been struggling with his bisexuality for a long time, but now he felt free. Besides, his mother was not a man.
Soon her chest started to spurt milk, and soon two more breast pair started to grow under them. Her sons hands worked her shaft in a way she found incredibly pleasurable. It wasn't long before a tail was formed behind the woman. Kate was always a chubby woman, but her fat was now giving way to a muscular, yet feminine physique. Not long after her sixth orgasm, Alex's hand gave way to Lucy's expert tongue, while the first one continued to feed on her milk. The yellow fur of a golden retriever soon started to grow on her exposed skin, signaling Lucy to present her snatch to her. Alex guided his mother to Lucy's backside this time, instead of try to pull her away. Soon the woman was plunging deep into "their" mate once again. Alex started feeling left out for a while, but an idea presented itself while he watched fur cover Kate's shapely ass. First he probed her with a finger, giving Kate the clue to move her tail aside for Alex to mount her from behind. As soon as he entered her, all three howled in pleasure as the threesome continued with Alex ravaging his mother's asshole.
Meanwhile Melanie was in the office as her room was a smelly mess, she was wearing some great noise canceling headphones, hearing music and pondering on what happened. She still remembered the blowjob she had received from her best friend. She didn't know how to feel about the situation. What will be her fate? Back to goat? Or does the family stay together?
