"Shush you," Supergirl snapped, "You'll give this pervert more ideas. Anyway I tried the school girl look a couple of years back. I had the belly shirt and everything. But this. It's just a bra. Pretty standard really, not even any lace" Supergirl tried to puzzle out it's meaning "Although to fill out those cups I'd have to be... "
The bra disappeared in a flash of light.
America finally closed the distance between herself and the Kryptonian girl. "You'd have to be what chica?"
"I'd have to be...as big as my COUSIN!" Supergirl exclaimed with worry as her nipples began to tingle. The tingling wasn't altogether unpleasant. And then the squeezing. and the feeling of her breasts feeling held by a pair of hands. Memories of heavy petting sessions with Brianiac 5 flashed across her memory. Memories of make out sessions with her lover from the future, the constriction of her uniform top and her embarrassment about what she suspected was coming all combined to turn her cheeks beat read.
America, concerned that the pretty blond was some kind of panic attack moved in closer to comfort her. Only for Supergirl to arch her back, thrusting out a suddenly much larger chest pushing the pretty Latina back and taking her by surprise. Loosing balance on her stiletto heels America began to fall backwards but instinctively saved herself by hovering a bit in the air. Then came a tingle to remind her of the first rule of the chain...
"Oh!" Supergirl wailed as the sensations of the her larger more sensitive breasts combined with the stirring in her nether regions from the empathetic chain that bound the two young women. "America, Your flying! You're flying!, OH ROA!" Supergirl exclaimed as the heat started to build.
"Sorry! Sorry!" America apologized, returning to the ground. The sensations subsided and Supergirl started to collect herself. Her uniform top a long sleeved blue top with a stylized red S on the front was now stretch across two massive mammmaries. The S shield was not only distorted but the new breasts changed the fit of the shirt un-tucking it from Supergirl's red skirt and making it look like a belly shirt.
"Great! looks like I'm back in that belly shirt I outgrew a couple of years back. Huh. "outgrew" poor choice of words huh?" Supergirl sassed to distract herself from the embarrassment. She brought her hand up to sweep back a few stray hairs and was disturbed when her for arm brushed against her newly expanded bust.
America, her sisterly solidarity with a fellow super-heroine fighting a raging battle with her lesbian libido attempted to engage Supergirl again, "So you said your cousin is this...endowed?"
Supergirl latched on to the conversational olive branch and attempted make small talk, " Powergirl, she's a super-heroine like us. I think she's trapped in here somewhere too. Kind of my cousin, kind of my big sister, it's complicated. She's older then me so I always wondered if sooner or later I'd...fill out, like she did. Guess it was sooner rather than later"
"So" America fiddled with her new hair style and tried to sound nonchalant and casual when she asked, "Is Powergirl seeing anyone?"
