Sarah levitated above the water in her tub and willed her towel to come and dry her off. As she did, she made it gigantic, fluffy and very absorbent, and caused all the water in the tub to vanish (transporting it, cleaned of all impurities, into the city's water plant). She let her towel caress her as she hovered off the ground, passing right through the wall between the bathroom and her bedroom.
She made her towel fly off her, drying it instantly and folding it before transporting it back to its usual place, and settled herself gently on her bed.
She reached toward her pussy, but let her hands fall to her sides as she simply stimulated all her erogenous zones with her mind.
"OHHHHHH MEEEEEEEEEEEEE!" she screamed as she reached an orgasm that would have left any mortal instantly comatose, and after about a minute of intense pleasure she reached backward in time to soundproof her bedroom. She continued her orgasm for a few minutes, until a thought crossed her mind that made her grin.
Focusing on her crotch, still in the throes of orgasm, she made a cock grow above her pussy, complete with huge balls. She made it fully erect and lengthened it until it was more than three times longer than her loser ex-husband's was. It, too, was immediately overcome by Sarah's orgasm.
Huge ropes of cum blasted from its tip, leaving dents in the ceiling and the wall opposite her bed, while juices flooded from her pussy, until she had to levitate slightly as her bedsheets became soaked with her own sexual fluids.
After about an hour of sexual joy, Sarah ended her orgasm and hovered, panting, until she simply restored her energy with a thought.
Getting rid of her dick (but promising herself that she'd bring it back), she floated, still prone, out of her bedroom and into her living room, settling herself on her couch, which became huge, comfortable and covered with leather as she did.
"Hm," she said to herself, "this is hardly the sort of house in which a Goddess should live."
One simple thought later, while the exterior dimensions of her house had not changed, the interior had become infinitely large. She ensured that Abbie and Alex wouldn't find anything about their new home strange, and that, like her, they could teleport themselves and their guests to any room in the house.
Thinking of her daughters made her want to look in on them, so she waved her hand at her gigantic, wall-spanning TV and it came on, giving her a live feed of Abbie.
She frowned. Abbie was in PE. Sarah had tried to talk her daughter out of it, since she'd never been very good at most sports, often being the worst in the class, and today was no exception as her elder daughter's classmates were running circles around her in soccer. Sarah reached out with her powers and changed all that.
Nobody noticed anything, but Abbie quickly grew to a towering 7'10". Sarah gave her daughter perfect coordination and aim and made her the best in the world at every sport, further supplementing her skill with superhuman strength and speed, a slight amount of prescience and telepathy, so that she'd know what other players were about to do and, if undecided, could nudge them into doing what she wanted, and an aura that made her opponents temporarily worse at whatever game was being played and enhanced her teammates' skill similarly, though not to the extent of hers. She also made her completely invulnerable, incapable of sustaining even the slightest injury, immune to all weather conditions, and tireless, easily able to run any distance at top speed without being winded in the slightest.
Sarah smiled as Abbie immediately began dominating the game, scoring goals every ten seconds, the opposing team helpless before a Goddess's daughter.
Smiling, Sarah switched her TV over to Alex, who was writing a test.
Sarah zoomed in on the test paper, grimacing as she knew that Alex would only get about 60% between incorrect answers and questions she wouldn't have time to answer. Waving her hand, she made Alex the smartest human in the world and an expert in all fields of study, far outclassing everyone who had gone before. She gave Alex superhuman speed equal to her sister's, which allowed her to erase all the wrong answers and fill in the right ones in the few minutes left.
Not wanting Abbie to be able to bully her younger sister, she gave Alex strength equal to Abbie's. When the test ended, Alex swung her book bag onto her shoulder--it weighing, to her, a minuscule fraction of an ounce--and left to go to the bathroom.
Sarah frowned at the thought of her daughters having to use the bathroom like ordinary people, and changed them so that their bladders and bowels simply emptied into the aether, further changing them so that they would be free of all disease, not even able to pass any on by touch. Alex nonetheless continued toward the bathroom and started to do her makeup.
Sarah frowned once again. Alex's face writhed, until, while she was still recognizable, she was so beautiful that any makeup would merely detract from it. Like Abbie, Sarah made her younger daughter invulnerable and tireless, with weather not affecting her in the least, and altered her body to be absolutely flawless. Her hair below her eyes vanished, never to grow again. The hair on top of her head, meanwhile, blasted out until it not only almost touched the ground, but was also in an amazing hairdo.
Alex then grew, becoming as tall as Abbie, but unlike her sister, who had a body ideal for sports, Alex grew extremely feminine curves. Her breasts became three times as big as her mother's--Sarah didn't care since she could always change that--and her ass grew similarly. Her waist became seemingly impossibly small. Her clothes changed, too, made from a material that was as invulnerable as she was and that hadn't existed until that moment. Her top simply wrapped around her gigantic tits, with her huge nipples denting it significantly, and as only a tiny clasp held it together at the front, while the top itself was a band just wide enough to cover her areolae, rapidly thinning to a strap only a single molecule thick, almost all of her breasts were exposed. Her panties became what was, on her, a tiny thong, a small strip just covering her labia and otherwise being as thin as her top's straps, and her shoes gained eight-inch heels with no platform, the monomolecular straps winding up her legs almost to the knee. To complete the look, Alex gained jeweled earrings and a necklace of the same jewels, which, like her clothes, hadn't existed before Sarah created them, and white gloves without fingertips, reaching up her arms almost to her shoulders.
As soon as Alex walked out of the bathroom, she ran into the principal. The man spluttered at her almost nonexistent outfit, but a smile from Alex, along with a firm grip on the principal's shoulder, left him in full agreement that, in her case, an exception could be made to the school's dress code.
