She mixed together 4 Mind+ vials, and 3 Submissive+ vials, adding a little Magic+ to the mixture before massaging it all into Gabe's skull. Under her dexterous fingers, she could feel Gabriel's head swelling, her brain and mind growing larger and stronger. She released her somewhat from the coils of her cock, allowing Gabriel to speak. "Are you... you, again?"
"Yes. I am me," Gabe replied, in a voice that echoed with tranquillity. "Thank you for freeing me, I see now my pussy was controlling me, and forcing me to act against your wishes. I am... so sorry for that, mistress."
Mary cocked an eyebrow and released her completely. Gabe made no attempt to move against her, though her eyes glowed faintly blue. Her pussy lay dormant. She'd even stopped producing pheromones.
"You were right to give me those Submissive+ vials, Mary. With the control you've given me over my own body, who knows what I could have done to you." She bowed her head. "I can read your thoughts. You're wondering why I called you mistress. It's because now, I have the singular desire to serve. Give me whatever vial pleases you, and I will drink without hesitation. You may mold me to your will."
Mary tilted her head at that and grabbed another cup. In went some more Submissive+, along with 5 vials of Loyalty to make sure it would always be she that Gabriel served. Then, another dosage of Mind+ and two of Intelligence+, some pure sexuality, and a good heaping of Power+ and Magic+. She held up the concoction to Gabe. The girl swallowed it without hesitation in a single gulp.
As soon as the glass was emptied, it slipped from her grip as her hands came up to grip at the sides of her head. The glass did not break, however, as it hung in midair, surrounded by a faint blue glow. Gabe's head expanded into a great, bulbous growth, her skull the size of a beachball. Her feet lifted off the ground, and as she opened her eyes again, they were a pure, glowing blue-white. Mary found herself floating upwards too, caught in the rapture of Gabriel's new psychic powers. Her mind was unparalleled in power, and her intelligence and wisdom were off the charts. She could do whatever she wanted with her powers, crush the whole world if she wanted to. But she didn't, and simply floated Maru closer to press a gentle kiss on her cheek. "Is this good enough for you, mistress? Have I done enough?"
"It's... acceptable," Mary replied, with a hint of a smirk playing at her lips.
Upon hearing this, a great shockwave flew from Gabriel, and two vials floated over to her. The Magic+ and Power+. She doused herself in them, pouring them limitlessly over herself as they infinitely refilled. Her muscles took on extra definition, though they did not grow, as her body shook with all the power of the cosmos. Her mind expanded to encompass all of the known universe, and every alternate dimension and timeline. Her power was endless, her will indomitable, and yet she only had a singular purpose in it all. Pleasing Mary.
The vials stopped pouring. Gabriel opened her eyes, showing the vastness of space held within them. Galaxies floated by. "There, mistress. I cannot fail you now, because I cannot fail. I can bend reality itself to your whims in seconds, should you ask for it. And I have bound myself to you across all timelines and all dimensions. I am forever yours."
Mary, a little stunned, gaped. Then, she tried to correct herself. "Yes, very good. Now, could you be a good slut for me and lay on the bed?"
"Yes, mistress! I will be the very best slut for you!" In an instant, Gabe was on the bed, legs spread, wearing a skimpy maid outfit with holes specifically to give access to all of her holes. The tongues in her breasts lolled out, as she pulled the perfect needy-bitch-in-heat face. Everything was straight out of Mary's fantasy.
Mary's balls thumped a heavy rhythm, and her cock twitched. Suddenly, she didn't have a choice as Gabriel speared herself on the 8-foot dick. "Aiii~" she cried, as it stretched her to her limits. "Oh, mistress, your cock's so big! I hope I can service it enough~"
That was enough to kick Mary into gear. She grabbed Gabriel's hips and slammed her down onto her shaft, even as Gabe gulped down several doses of Elasticity+. Each time, Mary shoved more and more dick into the girl and felt her insanely dextrous vagina massage and stroke its length. The muscles clung to it trying to force it deeper and deeper into the stretchy, submissive goddess.
The two began to float off the bed, and Mary slammed Gabe into the roof, shoving her down as her hips bucked wildly against her. Gabe's breasts spewed liquid, and her pussy-mouth orgasmed in delight. Being fucked in zero gravity was an experience like no other. Mary bred her like a wild beast, thrusting her cock harder and faster, both using their dexterity to make sure Gabriel was filled to the brim. Finally, after a good, long, and rock-hard fucking, Mary felt the release. Her six balls thumped loud and hard, as she squeezed every drop of mutant cum out of her.
The two collapsed Gabe righting gravity for them to fall on the bed. She, being a true goddess now, wasn't quite spent, but Mary had just been blessed with the most powerful being in the universe, so she was happy to be spooned by her mistress. Gabriel smiled, and the stars sparkled in her eyes. She couldn't wait to see what her mistress would do to her next.
