Melanie always had a bed habit of sleeping when listening to music, that was one of the reasons she could never drive with the radio on. While sleeping this time, she dreamed of Lucy and her transformation. In the dream, she was a goat, until Lucy "saved" her, and she was a beautiful dog like her, running around on all fours. The dream quickly became erotic as she felt Lucy licking her pussy, and then both were human shaped dogs. In the dream she reached a powerful orgasm, so hard she was woken up. She opened her eyes, and saw she was naked and someone was licking her between her legs. She thought it was Lucy at first, given the canine shape of their head, but the red hair that blended with golden fur on the top of her head made Melanie deduce this was her mother, Kate.
Not sure if this was still a dream, Melanie didn't react until another orgasm sobered her up. She cried and moaned while desperately asking what her mother was doing. Kate stopped licking her only to say something that disturbed her, "Making you perfect". When the drowsiness and shock wore off, Melanie realized how incredibly horny she was, it was like she was hit by a truck and she could no longer move and she started to wonder if she wanted to.
"You bother wants some attention too". Alex had entered the room, asking Kate if Melanie would be growing a penis too. So far it didn't look like she would. Hearing that, both mother and son lifted her off the recliner, Alex positioned himself in front of her and Kate on the back. A tongue soon assaulted the sister's exposed asshole while Alex played with her tits, that were soon to number six as the nipples started to show on her abdomen.
Melanie wanted to resist, but that was never her forte. She gave in so soon when she was a goat, and now she could only let her pleasure guide her to be a dog. She soon realized how happy it made her feel she was not going to be a goat again, her family was made up of dogs now, and that is what she should be. Alex had started to tease her pussy with his cock, and her resistance was finally cracking completely. She grabbed her brother's head and turned it to her before starting to kiss his muzzle. Her human mouth wasn't quite able to actually kiss him, and that frustrated her but she kept trying, causing her face to elongate. Eventually her tongue and Alex were dancing together as he trusted his cock inside her. Not to be outdone, Kate took her butt as her prize, sandwiching Melanie as fur covered her body. Lucy watched the spectacle from the door, still too full to participate. She wondered who would father her first litter. Not that it mattered to her, there would be many other's to come from both her mates.
