Try and get some answers, but you're a little busy

The sharp sound reverberated through my mind, clearing away the fog and letting me think again. Not that I could think very clearly, since I had to process everything that had just happened. My eyes darted across Evelynn's body in confusion.
"Wh... Wha... What the hell was that?!" was all I could manage.
"Let's find out!" She responded, excitedly hopping from one foot to the other. Without think, I did exactly the same thing, matching her almost perfectly.
Clearly, the sight of me matching her excited movements despite my utter confusion was too much for her, and she laughed hard. "AHahahaha! This is too much!" she managed to get out between laughs. As she laughed, she would occasionally step back and forth to keep her balance; steps which my own legs matched, and completely refused to move in any other way. I was completely unable to move from that spot of my own volition, and it was a truly bizarre feeling.

While I was still getting to grips with the situation, Evelynn regained her composure. "Right, now let's get to the good stuff!" She did a small jump in place, and then started dancing. Now I was really along for the ride.
\~~~~

"Evelynn- Woah!" My question was derailed as she made a wide step to the right and cocked her hip, a big movement that I really wasn't ready for. I was surprised that my body was able to stay upright with my upper body completely out of sync with our movements. I tried asking again, as I was figuring out how to keep up with her quick steps and hopping around. "Seriously, what's going on? How in the world did this happen?"

Evelynn refused to stop moving as she answered me. "So, this is gonna sound crazy?"
"Crazier than you suddenly having a hypnotic butt?"
"Genuinely, yes. As it turns out, my parents have got minor super powers! I didn't know about it at all until they told me this morning. My mom's got a temporary enhancement power that lets her make a part of her body stronger for a while, and my dad has like, a supernaturally soothing and convincing voice. Apparently super powers are genetic, and if both parents have one then they can combine in weird ways! So I guess I got super powerful charisma in a... specific part of my body."
She decided to switch up her dance moves, turning so we were facing each other and taking a couple steps closer. She started gradually lowering herself down to the floor, sashaying her hips from side to side as she went. I was **** to follow her, and it felt absoultely ridiculous having those seductive feminine movements **** onto my body. If anyone else could see me I would have been soul-crushingly embarassed; but with Evelynn, at least it could just feel like playing.

"Anyway, I mentioned this while you were under," she continued, "but I woke up this morning and it had just happened!" I almost didn't notice at first- crazy, I know, but I just go on autopilot when I wake up. But then my sister came into my room to tell me breakfast was ready, and she just stopped mid-sentence once she got a good look! Honestly it was pretty weird at first, but that got me to take a look in the mirror and see what happened to me. Looking at it even made me a little woozy, hehehe." She giggled remembering that, and switched her moves again to something resembling a belly dance. My hips shook back and forth, my pelvis and stomach **** to gyrate and move in a circle.

This new spectacle sent her laughing again, though that didn't slow her down at all. "Ooh, Jacob, you're actually a really sexy dancer, hahahaha", she managed. "At least, you are when we put my mind to it!"

With these new, fast dance moves I was starting to feel my body getting tired. Not just my legs, but all over as I was having to constantly react to my own movements to keep my upper body stable. I managed to focus long enough to say, "Could you please stop and finish explaining?"

That got another good laugh out of her. "No on the first point, but yes on the second. Sorry," she added quietly. "Once my parents got a look at me, they knew they had to explain everything. Apparently their powers had come in in their early teens, so they were wondering if I'd get anything significant from them and didn't want to say anything if I didn't. So yeah, I found out my parents both have super powers on top of just waking up one day with hypno-cheeks! I was shocked at first, but then I realised, having a power like this is actually pretty rad. Especially if I have the right person to share it with."

With that, our dance suddenly stopped. She stopped mid-step, facing me with her right leg out in front of her. This time she adopted a domineering persona: her head was tilted slightly down and her eyes were locked on mine, with a satisfied smirk across her face. She began to slowly strut forward, exaggerating the sway of her hips and milking the movement as much as possible. My own body tried to match her seduction, thrusting my hips left and then right as we slowly drew closer towards each other. I felt ridiculous, feeling my legs trying to flaunt nonexistant womanly curves. Although, I couldn't deny it: getting dragged along by her was this was really doing things to me. My torso and arms were completely along for the ride, with nothing to hold onto.

Eventually, we had closed in on each other. Evelynn draped her arms across my shoulders, and slowly moved her right leg between my legs, so we were both straddling each other.
Her voice came low, and seductive: "One more thing. Then, you can stop." Then she pulled me in for a kiss.

We held that kiss for a while, probably in part because we were both so tired from dancing. It was so comforting, to feel her and know this was the girl I loved, and the girl who loved me. But my mind was still racing with everything I had just learned and seen. Super powers? Hypnosis? Mind control?

While I was still trying to process everything, she broke off the kiss, and I could feel my legs returning to my control. It turns out, you don't notice all the small movements you constantly do until you can't do them for a while. She took my hand lightly in hers, and led me over to my brown leather couch. All the showmanship she had displayed had vanished from her as she said, "I might have gotten a little carried away there, sorry about that. I was just really excited, and I knew that you were the first person I needed to test my power with- God, 'my power' sound so weird to say! So, if you need a sec to take everything in, I get it. I guess it's your turn to set the pace now."

I was still coming to terms with everything that had happened, but one thing really stuck out in my mind.

'Test my power with', she had said. Not 'on'. 'With'.
