Can't Go Wrong With a Classic

''You should go first, start with something fun'' Ruby was cuddled up to me sideways, her hand still resting on my stomach.

I opened the app on my phone, beggining to type

Kristens boobs will grow into soft G cups

''How about that?'' I said, offering my phone toward Ruby, so she could read it

She gave me a wry smile ''I knew you enjoyed that. Go ahead''

I tapped 'Confirm' and we both focused on Kristen, waiting for the change to take place

Kristen was visibly uncomfortable as we both turned to stare at her. The discomfort was quickly replaced by surprise though, as her hands shot up to her chest, her boobs pushing quickly out against the stretchy material of the leotard. It was only a moment before they reached a size that threatened to overload the material, already stretching it thin enough to see through

''Warn me next time'' Kristens hands were overflowing with soft tit as she spoke, her voice a little ragged

''Pfft, where's the fun in that'' Ruby taunted ''Oh, idea, let's add a little perkiness''

Kristen crossed her arms over her boobs protectively, pushing them together and unintentionally causing her to show quite an impressive amount of cleavage

I heard Ruby tapping away at her screen for a moment, before setting the phone down.

''Hey, I let you see mine'' I protested, nudging Ruby across the couch a bit.

''And I appreciate that, but you're missing the show'' Ruby kept looking forwards as she spoke, eyes not turning away from Kristen for a moment

Looking at Kristen, I could see her rolling her shoulders and making a bit of space between her boobs and her crossed arms as her tits slowly crept upwards on her chest. They weren't as perky as my implants, but some of the sag had been taken out of them, making them look firmer as well

''Take your arms out of the way'' Ruby sounded giddy as she spoke

Clearly she was expecting something more, and Kristen apparently thought so too, as she looked down at her boobs, eyes going wide ''You didn't!'' She wrapped her arms tight against her boobs, pulling them away quickly as she reacted as if something had stung her

''I just thought I'd make sure you enjoy them. Now let's help you stop covering up so much'' Only as she spoke did I realize, Ruby had pulled out her phone and was tapping away at the screen again.

Whatever she did, didn't seem to work as Kristen kept one arm draped across her boobs as the other dropped between her legs grabbing at the crotch of the leotard.

''Whoops, let me just change that around'' She giggled a bit as she tapped away at the phone again

''What did you do?'' I leaned across to ask Ruby, as Kristen continued to palm at her crotch on the other side of the room

''Made her a major exhibitionist... Ah, here it is, confidence, that's what I was looking for'' With a few more taps on the screen she looked back towards Kristen, who was now upright, one hand still massaging between her legs as she moved toward the couch. Her arm having moved away from covering her boobs, making it clear what else Ruby had changed as her nipples made prominent dents in the fabric.

She leaned over Ruby, one hand to either side of her on the couch ''This might make things a bit difficult, unless you want me to jump on you center stage during your show tonight'' Kristens voice was breathy as she leaned in closer to Ruby, starting to kiss down along her neck.

Ruby stood up, pushing Kristen up off the couch with her as she leaned down to the shorter brunette, sharing a heated kiss

I pulled my phone up, opening the app again
