Tone it down

You waved a hand dismissively at Safiya's weird snake trick. "I can't, that's too much. She's still whimpering and everything! Could you do something else?"

Safiya nodded her serpentine head sticking out of Stella's mouth. "Very well, I'll just go fully inside her for now. I don't intend to leave this body just so you can fight with her about everything, we are going to stay put here for at least a little while, so for a while... I'll simply assume the role of loving, caring girlfriend!"

Stella whimpered particularly loudly at the idea that she was going to lose all control whatsoever, but Safiya quickly retracted into Stella's mouth, until nothing was left, as confirmed by Stella's hoarse yelling. "Taylor! Get this thing out of me and then get the hell out of my life!" She couldn't say anything more, however, as she held her head, feeling something entering it! You could see the bulge traveling up her throat until something seemed to physically deposit into her head--and then you saw the same happen in her arms and legs, bulges traveling down her body and into her limbs. Soon, she relaxed, and smiled.

"There we go," Stella said calmly, but you knew it was no longer her. "Just had to get myself adjusted in here. Usually I'm not changing from one thing to another inside another person, that required a little extra work than I'd thought. But! It is done."

"Is she okay?" you asked. Even though clearly she wasn't in control, you worried at least a little about Stella's well-being.

Stella nodded, and looked down properly at herself, examining her features. "She's fine. She still has all her senses, she's still fully conscious, she just has no part in how I move her about." With a grin, one far more playful than Stella's usual serious gaze, she strolled slowly toward you. "I think now you have the perfect combination here, if you ask me. The body of your girlfriend, the mind of a Jinn who will happily do whatever her talisman wishes... you could even control me to do as you wish, and that control would transfer to this body. Isn't that exciting to you? You could have Stella do exactly what you want, whenever you want. I won't mind. And her objections won't matter while I am in command of this form."

You tested that suggestion briefly, imagining Stella shaking her hips and spinning for your enjoyment. In response, her arms lifted up and she started to rotate, rolling her hips as she slowly twirled for you. She grinned at you. "See? You are already getting the hang of it." Once her full turn stopped, she continued to walk forward, until her hands rest upon your body, pulling close. This wasn't the Stella you knew, her behaviors were so different, even when she was playing the part of seductress. Now that you'd seen even just a glimpse of someone else in control of her body, you were starting to like this new configuration more...

Stella leaned in for a slow, passionate kiss, her lingerie-clad body colliding with yours. The fact that she had put on that lingerie for someone else mattered very little to you now that Safiya was still utilizing this body to maximum effect on you! Her hands slid along your sides, chest heaving as she inhaled sharply, pressing her body against you.

"I will say, though, she is quite slim. Modern women in all these supermodel aspirations are built like twigs. What about some more curve, wouldn't you enjoy that?"

You took a step back, glancing down at Stella again. Her face really was beautiful, and her body was well-proportioned and lovely, but it wasn't quite as exciting as Safiya's own had been. "I can agree with that. I mean, she's still a knockout! Way out of my league, even, all things considered. Seems that the promise of a big payday was all I needed with her, she thought I was building the next Hideki Corp... hmm. Are you saying you can change her?"

Safiya chuckled. "Well I am magic, you know. Here, how about I show you a re-skinned Safiya."

Before your eyes, Stella started to shift and morph, her limbs taking on Safiya's original shape--and then her torso! Her exaggerated hips and generous chest spilled out of the lingerie, which Safiya simply touched and let them dissolve, leaving the woman fully naked in front of you as her transformation continued. She gained the full hourglass shape Safiya had previously demonstrated, where her waist wasn't stick-thin but still looked quite slim in comparison to that incredible ass and long legs, and the bouncing breasts atop her frame! "Mmmmh..." Safiya had to brace herself against a chair. "Her body's quite tight, adding all my extra shape feels like I'm filling up a balloon to its limit..." Safiya ran a hand along her larger breasts, showing that they still jiggled, but there was a notable firmness to them with Safiya's extra mass pushing out against Stella's exterior.

Once she was done altering the body, as you tried to contain the excitement in your pants, she ran a hand along her own body, as the attire Safiya normally wore, that harem-librarian outfit, appeared back on her body, fitting perfectly. Even a pair of glasses appeared on her face, styled after the golden-rimmed ones bound to you. With a smile, Safiya posed--she had her original proportions from the neck down, but Stella's pale skin and her whole head remained! It looked almost like your girlfriend had head-swapped with Safiya, but you knew who was really in charge.

"Here, not bad, right?" Safiya swiftly returned to stand by you, her taller frame making it easier to stare into Stella's icy blue eyes. "This is how I'd often existed in other bodies anyway. Their outsides, my shape. It worked quite well for the King family for a few generations..."

Safiya leaned in for another kiss, using her stolen lips to her full advantage now as she pushed against you, to bring you to the couch. She adjusted her glasses, looking down at you with a hunger behind her smile. "Consider for a moment, Taylor, that like this, I can become a far better girlfriend to you, one you deserve, than one who will sleep around and do things behind your back. You and I are already bound in a way far stronger than marriage, you know."

You cautiously planted hands on Safiya's hips, and she smiled and wriggled her hips at your touch. As you grew bolder, your hands started to travel along her body, to a patch of bare skin at her waist where her stomach was exposed to you. "You would stay as Stella long-term? You do this a lot?"

Safiya nodded. "Jinn and humans can certainly do many things together on their own, but it had always been most fulfilling to use a human host body for everything I'd done. That's what allowed me to become someone's ideal girlfriend, or wife... and then they would go on to make me become a mother..."

You gulped at the thought of what Safiya was saying. Becoming a mother?! Safiya grinned wider, leaning back and putting her hands on her stomach, guessing correctly what was running through your mind. "Oh yes. If I stay long-term in here, I would let you put a baby in this belly. As long as I am in charge of this form, it's my choice and yours. If you would want to start a family, to become great like the King family and have heirs to your legacy, I can use Stella's body for all of it. Something to consider."

Safiya leaned close, her stolen face and hair tickling along your own features, as she gets within an inch of your lips. "For now... let's have some fun with her."
