Rework her relation to normal space

Jackie pondered how she was going to fit anywhere. She didn't want to risk getting stuck in a small space, or bumping into or blocking people. She needed to start from scratch. She put her body and room back to how it was before she grew her extra arms, and got to work.

She made it so that space would bend around her, allowing her to be as big or small as she liked, but to take up the same space she would normally, subject to adjustment at her whim. She made it so that she couldn't accidentally damage anything or hurt anyone, regardless of her mass, but that the sounds of her movements would be perceived the same.

She walked down the hallway and out the door, standing in her back yard. She looked out at the horizon, and grew. The horizon fell away from her, and she felt the wind whistling in her hair. She turned around, and looked down at her house. She lifted one leg, and stepped over her house, then followed with the other, finding herself on the front sidewalk in two booming steps. She turned around, walked up the front walk, and reached for the doorknob. In spite of how far below her waist it had to be, her fingers effortlessly reached it, and she stepped through a doorway that was perhaps ankle-high to her, and into a hallway that bulged to contain her. She walked back to her room, the floor creaking in protest but remaining unharmed.

She looked around her stretched-out room, and restored the large inner dimensions. But she wanted more to it than just a larger version of her room. The walls around the door folded backwards until it looked more like a small shack, and the floor gave way to fine white sand, running down to lapping waves; Jackie's room was now a tropical island. She looked down at the coast; she'd been thinking of making it permanently daytime, but the bio-luminescence illuminating the waves was too beautiful to banish forever. She settled for making the position of the sun depend on the part of the island you were on, and making sure the various island wildlife could survive the unnatural lack of daily cycle.

She walked from the nightside to the dayside, her feet leaving massive footprints that quickly smoothed out and formed into dunes. Now she could take a proper look at herself. She started by growing out a penis again. She grabbed it and started thrusting, quickly jetting a giant stream of cum over the ocean. As good as it felt, there seemed to be something missing. She tried growing her testicles back out as well, and started fapping again. Somehow, this was much better, and soon enough an even larger spurt of cum slammed into the surf. She sat down, leaning against a palm tree, and lazily stroked her shaft while she pondered what to do next.

She wanted a companion, but she couldn't imagine that any ordinary person could keep up with her. She needed someone like her. Like her, but totally and happily subservient. With a thought, she created a duplicate of herself, with all of the same enhancements, but without her inherent abilities, and willing to do anything she said. With another thought, she gave her clone the name "Jill", wrote the same exemptions into law that applied to her, and designated Jill legally as her property.

Jill opened her eyes and looked down at her owner. "Oh, wow, I've got all of your memories. This feels weird."

"Good weird, or bad weird?"

"Don't worry, Jackie, making me feel bad weird is the one thing you can't do, not unless you really want to. Somehow, it feels right, but all the same, it's like I've got the memory of flexing a muscle, and now I can tell it's just... gone."

"Should I do anything about it?"

"I don't know. All that matters is what makes you happy."

Jackie thought for a moment, and altered Jill so that Jackie was aware of her desires, and Jill could once more will things to happen, but only with Jackie's consent. As the new awareness flooded her mind, Jackie was taken aback. She'd created Jill to be her companion, and that logically meant that Jill had to be attracted to her, but logic alone couldn't prepare her for the flood of adoration and devotion that she felt as Jill looked at her. "Could you suck my co—" She was cut off as Jill dove down and started slobbering along the length of Jackie's divine rod.

Jill's perspective made the sensation of penile stimulation totally different for Jackie. She knew, without question, that this was making Jill ecstatically happy. Jill's pleasure at pleasing Jackie spilled over her like the light of a star at its surface. As Jackie's cum spilled down Jill's throat, neither of them broke their rhythm, but Jill's own cock erupted in a hands-free orgasm that drenched the beach before sloughing easily into the ocean.
