She doesn't, Saethryda is ascendant once more

Saethryda was fuming internally. How could this happen to her! She was supposed to be the Goddess, not this worthless minion, and certainly not the loser standing in front of her old body. The truth was that somehow, frustratingly, she had been temporarily outsmarted first by the pathetic excuse of a man who had given her the power to begin with, and then by that bitch whom she had seen fit to bless with a body second only to hers.

Thinking quickly, and realising that a loophole seemed to exist given she had been unaware of the ring until Damiana put it on and swapped with her, a plan hatched in her mind. She inwardly praised the fact that she seemed to have kept her elevated intelligence allowing her to think quickly enough to get herself out of this predicament.

You see, John had been wrong when he thought taking down the outside barrier was enough to allow Saethryda to claim the ring. In his previous infinite planning – and supported by the safeguards of the device that sent him here – had ensured that multiple layers of defence existed to protect the ring. As it turned out, the ring itself was protected from being directly worn by Saethryda and done so with a limitation placed on her powers to prevent her from overcoming that limitation. Only John or another wearer of the ring could remove that limit. So, while she could storm into the sacred room with the outside barrier gone, she still could not wear the ring. That is unless someone was to do something so monumentally stupid as to give her a body which was wearing the ring without first removing the rings power.

Unfortunately too for Damiana, She was now in Saethryda’s Goddess body, which meant She now could not wear the ring. And after a snap of Her fingers failed to teleport it to Her finger She quickly began to realise something was wrong. Were it not for the shock at Her first act as Goddess failing – and the little self pleasure session She had started - She might have simply paused time, messed with Saethryda's mind, made her unable to speak or any of a thousand other ways to obtain the rings power. Having failed to do however gave Saethryda a window just long enough to shout “I wish to go back to before Damiana put on the ring”.

A brilliant flash emanated out from the ring, blinding John temporarily, but when he opened his eyes nothing seemed to have changed. He was still looking at the Goddess before him, She was still displeased with him, and Damiana was still slipping the ring onto her left middle finger. This time however, the Goddess is armed with new knowledge and snaps Her fingers, freezing Damiana in place where she stands. Confident once more She releases John from his magical bind to saunter up the stairs, swaying Her divine hips as she does and causing John's dick to twitch as it let out as string of precum into his pants.

John thinks She must be enjoying making him suffer, wishing She would just end it all, to which he feel Her voice in his mind say “oh no my dear, you may not know it yet, but you’re going to be well rewarded for this. You'll be staying close to me for eternity, alternating between suffering and pleasure, burdened with the knowledge that your friend there could have been both your lover and your Goddess."

Saethryda doesn't even bother to walk to the top of the stairs, having grown again as She approach to tower far above Damiana from a perch 10 feet below her. The Goddess reaches out a perfect divine hand and rests it on her head, causing Damiana’s eyes to roll back in her head. John had thought she was devout but pragmatic before, now she had only one purpose in life, to serve her Goddess. Assured of her new servants loyalty, Saethryda releases her binds, Damiana already knowing what her Goddess needs as she cradles the ring and says “I wish for all the power of the ring to be given to the Goddess”.

John stares up in amazement as the ring disintegrates into a stream of particles flowing into the Goddess’s waiting body. John watches as She seems to grow even larger, Her presence expanding and once again threatening to crush him, except that She won’t allow that. Her body gains another few feet of height, leaving Her nearing 30 feet tall, each of her breasts as large as Damiana’s whole body while limbs lengthen slightly and firm up with even more divinely perfect muscle. John isn't sure how it seemed that She became at least twice as beautiful as before. Finally, John lets out a ragged breath with a trail of blue dust flowing out of him into Her, the last connection to the device's failsafes transferred to now protect Her against losing Her power, it seems the Goddess is now truly unstoppable. He wonders briefly whether that means She could return to his original universe to wreak havoc there, and as he does he regrets the thought, She is still reading his mind and is intrigued by this development.

In a final act of cruelty, the Goddess shrinks John down to a measly three feet tall, shorter than the length of one of Her perfect feet. Finding the comparison amusing, the Goddess snaps her fingers again John finds himself unable to see or breathe, feeling his body strangely distended but wrapped around the softest and nicest smelling object in the universe. He decides this doesn't seem too bad until a crushing weight presses down upon him, before easing temporarily only to be slammed with the weight hitting him again. With a mixture of both sadness and sinful pleasure, he is able to conclude that he is now one of the shoes of the Goddess, consigned to spend eternity underneath Her mighty gait.
