Power Girl has Wonder Woman over for a sleepover

"Hey, Diana?" Power Girl spoke as Wonder Woman's dull eyes slowly fluttered open.

"unghhhh..."

"Are you awake?" Power Girl asked, bending over at the hips to get a good look at Wonder Woman's dopey half-asleep face.

"Wh-what? Where...?"

Wonder Woman lifted her head, and looked around the room. She was in somebody's Watchtower quarters, but it wasn't her own - spotting a well-endowed mannequin wearing a spare white suit with a red cape, she realized that she was in Power Girl's room.

"Are you okay?" Power Girl asked, face a mask of concern. "You hit your head pretty hard again... I thought it would be best if you slept here tonight, so that I can keep an eye on you."

"Sleep? No, Power Girl..." Wonder Woman objected, sitting up. Only now did she realize that she was on top of the soft sheets of Power Girl's bed, as her hand made contact. She paused to look down at it, before looking up to Power Girl again. "Whatever happened, I'm fine. I can sleep in my own room."

Power Girl scrunched up her face and clicked her tongue.

"I'm not sure... you weren't looking so good earlier..."

"I'm fine!" Wonder Woman snapped back, her Amazonian pride insulted. She rose even more, about to stand, when Power Girl quickly stopped her with a hand.

"Please, Diana?" she asked, batting her eyes. "I know you're fine, but just... for my sake. I'd worry otherwise. I know you're alright, but I don't think I'll get any sleep tonight if I can't make sure of it..."

Wonder Woman stopped, and sat back on the bed again to consider. Power Girl grinned internally, spotting her opportunity.

"It'll be like a sleepover!" she said excitedly. "Come on, it'll be fun! It's just the two of us here right now anyway, we should be strengthening our bond like this!"

Wonder Woman felt like something was off, but she couldn't quite say what. And, admittedly, she did have quite the headache... getting back to her quarters might be a lot more stumbly and painful than she was willing to go through, when she had an easy out right here. And even though her subconscious was screaming "no" at her, strengthening her bond with a female ally did seem like a good idea...

"Alright," she said at last. "But only for tonight."

Power Girl clapped her hands in a girly display of excitement, then used her superspeed to whisk them both under the covers together. Wonder Woman barely blinked before she was tightly tucked in, like her mother used to do for her, with the uncomfortably welcoming feeling of being spooned by Power Girl. Her famous bosom and powerful thighs pressed gently against the Amazon warrior's own back and thighs, big spooning her. The feeling of being the little spoon was pretty insulting to the proud Amazon, and she grumbled under her breath.

"Want anything before we go to bed?" Power Girl asked, snuggling in closer. "A glass of water?"

"This is humiliating." Diana replied. Pretending to not hear her, Power Girl reached over and turned off the lamp, putting the room into darkness. Diana guessed it was time to sleep. At least she was quite comfortable, if a bit embarrassed...

A short amount of time passed before Power Girl interrupted the silence.

"So... Diana," she said, rolling onto her side and propping her head up on her hand. "How big are you up there, hm?"

"What?" Wonder Woman asked, confused.

"Your boobs. I wanna know if mine are bigger."

"Power Girl!" Wonder Woman was completely shocked. "That's completely inappropriate!" she said, rolling onto her back and turning the light of the lamp back on to stare at Power Girl in shock.

The young Kryptonian giggled. "Don't make me pin you down and measure you."

"You- You-" Diana spat, utterly insulted.

"Alright then~!" Power Girl announced, rolling up to her knees to do exactly that.

"Hey- Hey!" Wonder Woman shouted, as Power Girl started fighting to secure the Amazon's wrists and mount her hips, to pin her to the floor. She struggled and fought back from her back while the giggling blonde continued her ****.

"Ooh, are you fighting?" Power Girl teased. "C'mon, just let me measure you, I won't tell anyone if I'm bigger..."

"What's come over you?!" Diana demanded. "Power Girl- get OFF me!"

Power Girl spotted an opening, and took it. Reaching forward, she grabbed a hold of the glinting metal eagle cresting Wonder Woman's costume bustier, fingers crushing the metal as she yanking it from Diana's chest and threw it across the room. Wonder Woman couldn't believe it - her fighting arms immediately went to cover her exposed tits as her face took on an expression of complete shock. N-Nobody had ever done this to her - nobody would have ever tried. She was Wonder Woman, famed Amazon Queen of Themyscira, mighty Warrior, Justice League founder - it was just inconceivable that somebody would try to pin her to the floor and rip her costume apart like this.

As her shock washed over into a rage, Diana roared, and lifted her arms to begin fighting back more earnestly. She beat her fists ineffectually against Power Girl's thighs, making her fat tits jiggle around, and making her breasts exceptionally hard to measure.

"Nnf! Stay still!" Power Girl ordered.

She reached out with one hand, pinning Wonder Woman's bare shoulder to the ground, while her other hand came back to deliver three hard punches to the chin of Wonder Woman, not aiming to put her lights out, but just to make her a bit more docile and loopy. By the end, with the connection of the third punch, the Amazon was totally out of it, and Power Girl could almost see the tweeting birds circling her dazed head as it weakly rolled side-to-side. Her look of rage was replaced by rolling eyes, and her pounding fists were now at the end of limp noodle-arms stretched out either side of her bare-titted torso.

"guhhh..."

"That's better..." Power Girl smiled at the humiliatingly pathetic bimbo before her.

If any of Diana's myriad enemies had been around to see this, this absolute sight, they wouldn't have been able to keep from cheering Power Girl on. A punch-drunk Wonder Woman teetering on the very brink of consciousness, with her marble-statuesque body and her plentiful bosom, her generous proportions, her healthy ass, her beautiful face, those galaxy-containing eyes all glazed over... seeing her so fucked up was like seeing the eighth wonder of the world - Wonder Woman defeated. A lot of people would have paid to come in and glimpse her laid-out form in all its beauty. To see her so weak and airheaded. To witness it happen, or just to witness the aftermath.

"Now then, let's see..." Power Girl mused as she pulled two lengths of measuring tape from a nearby desk, holding one between each hand's thumb and forefinger. She was becoming much more blatant and outgoing with her humiliations of Diana compared to when she first started, now 100% confident that she could comfortably take her majesty out and send her off to La La Land at any point she chose without much trouble. Diana's reputation seemed to be nothing more than a skin-deep facade after all, and the young busty Kryptonian was certain she had nothing to fear from this Amazon bimbo whatsoever. No reprimands to deliver without getting punched out first, and no reprimands to consider while her brain was so battered like this.

Power Girl lined up the measuring tape around Wonder Woman's exposed breasts, poking her tongue out from the corner of her mouth as she did so in a cartoonish display of focus. Power Girl measured Diana's famous boobs as they stood out bare and **** to the cool air, sitting atop of Wonder Woman's hips like a jockey riding a horse, or a rider taming a wild horse. Except that the horse was instead the punch-drunk remnants of a crumbling, once-great superheroine, who at the moment couldn't attempt to buck Power Girl off half as effectively as a wild horse might have been able to. And she was too fucking stupid to even try, with her quick-thinking warrior's mind on a hiatus at the moment, courtesy of the stacked blonde woman who'd made her so chinny in the first place.

"Hey, your tits are pretty fat!" Power Girl announced, pinching the two ends of the measuring tape in place around Diana's boobs. "No wonder you're so close with the best Leaguers here. But, let's see..."

Power Girl held the first measuring tape in place as she started to use the other length to measure her own mighty bosom. After a short time wrapping it around with only her one free hand, she finally had her answer.

"Ooh, yep! Mine are bigger~" she sang, tightening the measuring tape around wondie's breasts and squeezing them a bit with it. "Sorry, Princess, you lose again~~ the sleepy, genetically inferior Diana Prince~ loser boobs, loser boobs~" Power Girl poked and prodded Diana's exposed boobflesh with her long fingers tauntingly.

As the barely-there Wonder Woman groaned weakly in what might have been a response, Power Girl happily shifted off from her mounted position, humming a pleasant tune to herself as she rolled Wonder Woman onto her side. The Amazon Queen rolled over without any resistance whatsoever, ending up on one shoulder facing away from Power Girl, her arm limply dangling across her front side. Her bare, totally revealed tits shuddered as the tiny part of her locked away deep in that groggy brain understood the humiliating position she was in.

Power Girl herself lay alongside wonder woman's back, still humming her tune as she reached a hand over Diana's shoulder to go directly on top of the Amazon's bare tit and grope it. Her head was resting on her other hand, held up to get a slight over-the-back look at the queen of the amazons in her glorious defeat.

Power Girl just smiled, enjoying the view, the fondling, and the feeling of having put the royal bitch in her place. Barely awake and on the ground, hardly able to keep a single thought. Pathetic.

"Ouff, you got really fucked up." Power Girl commented, grinning as she spoke. She gave the tit a good squeeze, forcing a pleased sigh from Diana's lips and letting out one of her own, shifting her titanic breasts along diana's slack once-powerful back. Wonder Woman really wasn't looking too good... the media would be all over this if they knew the lows their idolized Amazon Queen was being brought to, the fogginess which engulfed her usually-sharp mind.

"y-you... what... wh-why are you doing this to me? I'm wonder woman..." the Amazon stammered out weakly, not really speaking to anyone. Power Girl just smiled, and groped Wonder Woman a bit more. After a moment of silence, the ditzy Amazon spoke again, saying her words slowly and partly-slurred, as if she was using them as a desperately-attempted means to formulate some actual thoughts rather than to communicate any existing ones.

"andd... h-howww...?" she croaked. "I sh-shouldn't... none of this sh-should... y-you... this d-d-doesn't..."

"Alright, that's enough, Wondie." Power Girl cut her off with a sigh, using a hand to roll her onto her other side and finding little resistance. Now lying on her other shoulder and facing in towards the younger superheroine, Wonder Woman looked into Power Girl's eyes, batting her own eyelids and face full of pleads for mercy. Power Girl smirked at this. "This is supposed to be a sleepover, and you're keeping us both up yammering like that," she said. "I'm going to have to smother you out."

Wonder Woman's eyes widened.

"n-nooo..." the fearsome Queen of the Amazons faintly objected, wriggling uselessly as the beaming-smiled Power Girl held her in place.

"Yep~" she said with a playful lilt in her voice. "It's bedtime, your royal highness~"

With a Kryptonian giggle and an Amazonian gasp, Power Girl guided wondie's face towards her chest, to smother her out for the night. Under the right circumstances, with the right buildup and the right power dynamic, the right emotions can turn even the greatest of heroes cruel. What was a playful beginning can progress into something much harsher... and unfortunately for Wonder Woman, she was on the receiving end of that power dynamic shift. And there was nothing she could do to stop it. Nothing but get smothered by boob until her whole body was stiff and submissive. So much for the famous Wonder Woman.
