Just stonewall her

While you can’t think of a good excuse right now, you can at least buy yourself some time. You answer that, “No, I don’t have any sort of deal for Mom to do me favors” and choose not to follow up with anything more.

Your sister is, understandably, not satisfied with that answer. “Alright, then… what? What’s going on here?”

Any explanation that would be remotely plausible would also need to be very far from the truth. Far enough that you’d have a hard time convincing anyone of it, much less someone who’s known you the entire time you’ve been alive. Best to just give her none. “Ok, so you are onto something with not knowing the full picture, but it’s kind of a lot to unpack, and complicated, and well, I really don’t wanna talk about it right now.” You try to pull a face like you’re skirting around something embarrassing rather than world-shattering as you take your sister’s hand. “Can you please just trust me?”

Hannah doesn’t answer right away, instead opting to sit there silently with eyes avoiding you. Well, except when they get caught on your naked chest for a second before releasing again. You resist the urge to cover yourself. “I want to…” she finally lets out.

Great! She’s open to the idea, just needs a little more convincing. You put on the table that, “You can keep all the pictures you take of me and Mom, as long as you send me copies.” You squeeze your almost-cleavage between your biceps to emphasize your role in this scenario. “Look Sis, if you’re worried about her reacting badly, I’ll take the fall for everything. I’ll say I put you up to it, this was all my idea, etcetera.” She nods wordlessly, considering what you said but not giving you an outright yes. You need to keep pushing. “Have I steered you wrong yet in this new paradigm? We had fun yesterday, didn’t we?” It’s hard to tell through her foundation, but you can almost make out a slight reddening.

“Alright, fine, you’ve twisted my arm enough” she relents, “I'll go along with your scheme on one condition.” You’re halfway expecting her to turn the tables, make it so you’ll be the one who owes Her a favor this time. Instead she just says, “You have to wait for me to get my good camera.”

“Yeah, sure” you confirm, and a moment later Hannah disappears into her bedroom. Left alone with only your half-naked self, you fidget nervously. To your surprise, she keeps you waiting for less than a minute.

When Hannah returns, camera secured in hand as well as by a strap around her neck, another, unannounced detail is different. Her pit stop also included a quick job with a wet wipe, clearing the dark lines of eye makeup dragged away by tears. Every time she fixes her appearance this way, you wish she would just leave it alone. Your mascara- and eyeliner-loving sister sheds the most beautiful tears.

With her appearance touched up, Hannah goes through the setup on her camera. While your sister is distracted, pointing the lens at a blank wall for complicated photographer reasons, you take the opportunity to apply the “method” of influence you mentioned earlier.

Activating ‘It Can’t Wait’

With no more active abilities left, and zero notifications about your experiments thus far, you hit the power button and finally pocket your phone. When you hear your mother’s bedroom door open, you estimate she took about as long as a brisk walk to it from sitting in bed, or maybe in her private bathroom, hopefully the former. When she emerges, she still hasn’t put a top on. The only difference you can see in her appearance is some reddish swelling around the eyes, less obvious than your sister with her streaked makeup earlier.

“Sorry for running off” your mother says timidly, “I didn’t mean to put a damper on things.” She mainly addresses you when she asks, “How can I make it up to you?” First impression of this new effect, pretty positive. She’s as thoroughly entranced as you’ve come to expect from the KDK.

Exactly to what extent your mother will “behave more desperately” remains to be seen, so you choose your next words carefully. “I hate to see Hannah all broken up over her artistic interest getting rejected. I think a good apology would be to pose for some family memories.” You gesture at the strapped-on camera, drawing your mom’s eye long enough to direct a stealthy wink at your sister.

Hannah manages to chip into the peer pressure with, “It would mean a lot to me.”

You pile on more words of insistence. “I think what Hannah was trying to do is really important, and I want to support it! Can you indulge me at least for a little bit?”

Even under the influence of partial mind control, your mom doesn’t automatically agree. She wrings her hands together while staring at her daughter’s camera, clearly uncomfortable with this idea. She looks back at you to ask, “Can I put a shirt on?”

Absolutely not, that would defeat the whole purpose. “That’s not how you were earlier though. So that wouldn’t be a memory, it would just be a lie. This is just for us, there’s no need to lie to each other.”

When you finish spinning the story, Mom simply points out, “But Hannah’s wearing a shirt.”

She’s got you there. If only you could “Clicker” Hannah too and get them both acclimated to being topless in tandem. “Well, she’s the photographer” you contrive, “so only you and me need to look how we did earlier.” Picturing the effect description in your mind for inspiration, you think of a way to sweeten the deal. You tell your mom that, “I realize it would take a Really Cool Mom to do this” so she knows that a reward of praise awaits her after she gives in.

Your mother’s breath hitches, but without any redness accompanying it. “If you think it’s for the best, Spring Flower” she finally gives in.

Hannah directs you on where to stand for the best lighting. Once you’re in position, you hold your mother by the waist, and she in turn goes for your shoulder. Hannah deserves nothing but gratitude for everything she’s tolerated from you today. None of her effects do anything to help normalize erotic acts in her mind, only her genuine trust in you. It’s incredible that you’ve managed to get her to play along at all.

After hearing your sister list out all your suspicious behavior this weekend, you’re a little worried she might be at her limit. If this NSFW photoshoot peaks at being pressed against your hot mom, cheek touching the side of her breast, you think you could live with that. It would provide more than enough personal gratification for you to declare this brunch and its consequences a success. Of course, the opportunity to ramp things up further is always appreciated…
