Stay home and do some research.

Despite the fact that leaving your mom alone with Amina could potentially lead to them to a repeat of them in your mom's bedroom, you could use the opportunity of getting Lynn's eyes and ears off your back for a little while so you can do some discrete research.

"Ah, you two go on ahead, I have some things I need to do first," you tell them.

"OK, hun," your mom smiles. "We'll pick up something for dinner."

You see the two off before returning to the house and logging into your computer. You type in a search for the sought after toy. As your mother told you, the toy will end up costing you a couple of grand from all the sources you find. You were saving up to buy a car, but if you spend the money on the toy, you can get Stacy to talk, which will give you something to use against Lynn and get back your magic, which you can then use to wish for your money back... it is a long shot and you have no guarantees that you can use anything Stacy gives you. Are you willing to risk your savings on the faint chance that it might help you get your magical wishes back?

"What'cha doin'?" Lynn asks, peeking over your shoulder.

You startle and turn to see that Lynn had changed outfits again. She is garbed in an scuba outfit and her hair drips salt water onto everything.

"Hey, careful!" you cry out, trying to wipe down the keyboard.

"Oh, did I interrupt your private time? Should I come back in five minutes?"

"How about come back never?" you retort gruffly as you continue to dry off your furniture.

"I haven't checked in on you for a while and was worried you might be getting yourself into some sort of trouble," Lynn replies dryly as she combs her fingers through her hair, magically drying that as well. "You know, you should appreciate my visits. It's let's make a deal with an all powerful being! So... what kind of kinky shit are you into, Williams?" She looks at the monitor, "Rainbow Princess? Now that's a surprise!"

With a wave of her hand that now carries an intricately decorated golden scepter, sparks of magical pixy lights envelop the nubile young blonde. Her scuba suit flashes a bright, blinding white along with her face and skin. The light fades and after a minute of blinking, you can finally make out spotty images. Lynn is now dressed in a pink gown with tiara, cosplaying as one of the princesses you don't recognize.

"Does this turn you on?" she asks in a sultry tone.

"Not really," you reply bluntly. "I was searching for a gift... not everything is about sex."

Lynn frowns. "Well, there is an extra dimension to you after all. Who's the gift for?"

You pause briefly, not willing to give her any hint that it's something to be used against her. "My mom... she's really into the princess stuff."

"Oh, is that why you sent her off with the genie? To keep this a secret from your mom?" Lynn asks. "And here I though it was just a scheme to keep me from seeing or hearing what you were up to."

"Are you really using her like a television?"

"You want to see what they're up to now?" she asks conspiratorially.

This could give you an insight on how Lynn spies on you through Amina.
