The four dragonesses heard a knock on the door, they looked at each other, and clearly thinking the same thing a sly smirk grew on the family's face as they thought of having another person joining them in dragon hood.
Mark got up and grabbed a handful of candies, as she slowly made her way to the door. Mark got to the door and set her self up ready to pounce and drag the person back into the house. She carefully open the door and wrapped her tail on the persons leg and quickly pulled the person in, closing the door quickly after.
Mark looked at the new victim/soon to be new family member, realizing it was their new neighbor Gabriel who had moved in recently.
Mark shoved the candies she had in her claws into Gabriel's surprised mouth and drag him into the kitchen so his sister/parents can see Gabriel's transformation.
Gabriel had no time to process what had just happen before finding himself in his neighbors kitchen in front off a three headed taur dragon,
he then felt hot and really horny.
Mary, Melissa, and Robert watched as their new neighbor began his transformation into a new dragon family member, they saw as scarlet red scales began to cover him, his hair turned blond and grew longer, he grew till he was as tall as them and as he grew he became curvy, 2 pair of breasts began growing out of his chest(4 boobs) they expanded to the size of watermelons, his dick disappeared into a new slit, now making him a her, two large wings grew out her back, a long tail grew, and her face became a draconic muzzle.
Gabriel had just become a sexy anthro dragoness with an extra set of boobs and given how she was panting a very horny one at that.
Everyone in the room could smell how horny Gabriel was, so Mary, Melissa, and Roberts gently pushed Gabriel down and aligned their draconic dick to her sex.
They pushed it in quickly hear a pleasurable moan leek out of Gabriel and began fucking her, with every thrust they made Gabriel moaned in pleasure and her sex squeezed their dick in return. They came shortly after quickly filling Gabriel with their spunk. Melissa cooed to Gabriel "welcome to the family my new sexy daughter".
