Pushing the men's room door open hard enough to dent the wall with the door handle Karen continued to kiss the young man as she guided him into a stall and closed the door behind her. As soon as the lock clicked she stepped away and pushed the boy back until he fell right onto the toilet seat, licking her lips she eyed the bulge in the young man's jeans as she gestured for him to stay sitting as she began stripping slowly. "Damn your really hot for it huh?" Said the kid out loud as Karen gave him a wink just before she pulled down her shoulder straps, pulling her dress down she freed her proud G-cup breasts, revealing she never wore a bra, her nipples stiff with arousal as she wiggled her hips to pull the dress down to her black shoes, no underwear to speak off as she stepped forward and looked down at her prize.
"Honey I'm gonna make you boil..." Going down to her knees Karen pried the pant zipper open, almost ripping the garment open as she pulled his erection free, licking her lips again she breathed in the testosterone scent before engulfing the boy's cock with her mouth. As she began sucking him off she could feel him grab at her blonde hair, on any other woman it would have hurt but for her it only spurred her on, already she was dripping wet and the smells were driving her mad with lust.
"Shit!... Gonna..."
Moaning with her lips around his cock Karen let the man cum hard down her throat, the taste making her eyes roll back as she examined how potent her prey was. Letting go of his erection with a pop of her lips she gave the young man a feral gleam of her eye before gulping his load straight down. She had a taste, now she wanted the whole thing. Sliding up to press up against him she positioned herself over his waist as she shoved his face into her deep cleavage, finally feeling him penetrate her pussy she moaned and wailed at the sensation, tossing her head back as she felt him nibble at her breasts. "Do it! Suck my tits, NOW!" Grinding and bucking her hips she mashed her breasts between his face, laughing as he started bucking his hips back to join hers.
Already she could feel him tensing under her, reaching deep inside and getting harder by the second. She almost scared him when she screamed out in orgasm just as he came hard, pumping into her pussy and filling her with hot cum. At last the burning emptiness had faded, her lusts evaporating as she panted and settled into her lover's lap. As soon as her heart stopped hammering in her chest Karen suddenly realised what she had done. Looking up in mild panic she found her lover exhausted and leaning back against the toilet and stall. Before he could blink or ask for her name the stall door exploded open and a whoosh of air blew through the rest room, leaving the boy alone with his pants undone.

Slamming her apartment door behind her and locking the door Power Girl pressed her back against the door and clutched at her chest, her dress back on the instant she flew out of the club, only now for it to be drenched in sweat and moister from the men's room stall she escaped from.
"Oh my god, oh my god, oh my GOD why did I do that?!"
Darting her eyes around her apartment she tried to calm herself down and try to think rationally. Somehow her transformation had made her... Amorous. Enough so that she screwed the first dick on legs she could find. She worried if this would happen again, whether it would compromise her position in the Justice League or even her reputation.
"How could this get any worse?"
As if on cue she suddenly felt a strange warmth build in her naval, followed by an unusual bloating as her belly began to swell. Pretty soon the swelling became more pronounced making her step away from the door and wander back to her washroom. Looking at her reflection she gasped as she watched herself swell and grow, her belly now looking like it was four months pregnant and growing fast. "Wha-what is this?" Then the growth sped up, making her gasp and moan as she felt a new wave of hormones rush into her system. Pressing up against the wall she could feel her hips widen, her ass and thighs growing thicker. Her breasts swelled up, her nipples getting darker as moister began forming at their tips.
"So hot... Burning up..."
Prying her dress off as it began to tear and rip, her belly had now grown to the size of a full term pregnant mother to be, her belly button popping out from the pressure within as she sunk down to the tile floor, rubbing circles around her womb. Then suddenly the warmth and pleasure had turned to pain as her water broke, a need to push forcing her to spread her legs as she began to give birth. In less than a few minutes the bathroom was filled with the sounds of crying and mewling, the cries nothing like a humanoid infant at all!
