Jeff resumed watching his ever evolving mother outside as she continued to walk around the backyard, taking a deep breath in and enjoying the fresh air. She began to stretch with all four arms wide, showing off her dexterity and her newly transformed lanky body, with all four pairs of recently grown breasts shown prominently on her torso.
Almost as if on cue, Jeff saw his mother give an uncomfortable look on her face as she started to massage her neck with two of her hands. Eventually the massaging turned into stretching, as she began pulling on her head to stretch it onto her right shoulder. Jeff watched, fixed on her movements, as her head seemingly began to shift farther across her shoulders to the right and away from the center of her body. As this was happening, a giant bulb started growing out of his mother's left shoulder.
Jeff's mom continued to pull her head and stretch it over, while a new hairless head began to grow out from that bulb. It started off as a faceless mass, but within a few seconds, eyes, a nose, ears and a mouth formed on the head, along with hair on the top of the head.
As the new head began to gain shape, Jeff noticed the facial features on this new appendage were a bit more...masculine, compared to his mother's original head. The chin was more defined, the new neck had an Adam's Apple and the hair grew into a short tuft on top of the head.
Almost as quick as the latest evolution began, it ended as Jeff's mom took another deep breath. This time, both of her heads inhaled and exhaled, as now four green eyes opened in the backyard.
Finally getting a good look at what happened, it seemed like the new head Jeff's mom grew was a masculine version of her original head, with the new face even showing a 5 o'clock shadow on (her? its?) face. Jeff watched as the two heads began to talk to each other outside, with a laugh coming from her original head as they began to walk back inside.
“Ah, much better.” Her original head said to Jeff as she walked back into the house, “Fresh air is all we needed to shake off that wooziness. Honestly, we should take more advantage of our backyard.” The new head added, "Why don't we set up dinner outside tonight?"
"Oh, that's a great idea!" Her original head added, turning to face you again. " Jeff, sweetie, what do you think?"
Jeff took a second to process everything, taking a nice deep breath of his own, trying to figure out how his mom now has a male version of herself sharing her shoulders.
"Sure, sounds great.....moms?" He wasn't quite sure what to call her now. Is the new head still technically his mother, or is he now like his uncle instead?
As Jeff continued to ponder that, his new parental figure returned to the kitchen to continue prepping their meal for the night, talking to each other as they made their way over. .
