Let's plan it out first (and then promptly fail at the execution)

"You mean I can just do it without worrying too much about the people I affect? That's awesome!" Kathryn is visibly excited. "I think I wanna do Megan, she's such a cutie! And I wanna know how her boobs feel..."

I throw her a grin. "You know we could always just give you breasts like Megan's with this, right?"

She pouts at me. "That would be such a waste of gems though when we could use this cool ability instead, don't you think? Where's your adventuring spirit, Captain? Don't you wanna boldly go explore some new territory?"

"I never said I would stop you from possessing Megan, if that's what you want to do. So what do we spend our 71 gems on then? We kinda unlocked a lot of achievements."

"Maybe something that helps me kiss people? Maybe you do buy me the Kiss HotKey after all? I could just walk up to someone and kiss them in front of everyone and nobody would notice!" Her voice has gone breathy again, and she visibly shivers with excitement.

It doesn't take me long to find the Kiss HotKey. It would normally cost 6 gems, but with the That's My Girl discount it's only 4. I swiftly add it to the cart.

While I browse for more interesting options, Kathryn excuses herself to take a belated morning shower. As I hear the water start up, some suggestions pop up on the app. There are some expensive packages like Water Nymph or Wet Dream with very vague descriptions, but my eye catches on something called Aquatic Growth which (predictably) makes her tits swell on contact with water. Sure, why not, it's only 10 gems after all the discounts and it's not like she won't like it. I buy it directly only to be rewarded with some moaning coming from the bathroom.

After a while of checking out even more customizations, Kathryn comes out of the bathroom wearing two towels (one on her head, one completely failing to hide her new and improved curves) and a playfully-accusing face. "I thought we didn't want to spend any Gems on making my boobs bigger"

"Even if it's an interesting option like water making them grow? Come on, you gotta admit there's some potential there! Besides they'll slowly go back to normal over the day when they're dry. I even threw in Quick Drying so you don't have to put the effort into toweling yourself off afterwards. It was only 12 Gems total!"

Intrigued, she removes the wet towel from her head to find her hair in perfectly dry condition beneath. "Huh. That's neat. So what else did you find for me? I assume that's not the only things you found in all that time I was in there."

I show her my cart.

HotKey: Kiss - (6) 4 gems

Great Taster - (12) 8 gems - Enhances taste perception of Girl without intensifying bad tastes; Girl's mouth, breasts and vagina have a pleasant taste to others

Deep Breaths - (9) 6 gems - Girl is able to hold her breath for extended periods of time

Deep Breaths modification: Shared - 1 gem - Customization extends to anyone kissing or kissed by Girl

"So there's the Kiss HotKey we talked about earlier. I also found this thing called Great Taster, and I figured that would make kisses more interesting for you." I give her a wink. "There's also Deep Breaths, which I mainly bought for the modification. I suppose they want us to go all in on this with all the custom mods they're offering."

"Ooh, those sound fun! Can't wait to try them out on someone!"

With Kathryn's approval, I speed through the buying process on my phone, pressing glowing pink button after pink button.

Wait, that last one wasn't in the order menu, that's the HotKeys tab that was open in the background.
