Wing it?

You had your long erection deep in the 'good' doctor's asshole when Supergirl came inside, and you felt like you were screwed... 'Oh, man...!' you groan in your mind. Supergirl was very surprised at what she saw, and just when you thought she'd be furious... She leaned on the inside of the doorway, with a smirk on her face. "So... What's up, Doc?" You couldn't believe your ears; Kara was bemused. And the next voice you heard, Dr. Katari's other personality, sent you a bit further into disbelief.

"It's only a routine checkup, Supergirl..." she mused, her body shifting back and forth along your shaft. "This was for his own good." You couldn't believe that Kitty was still tight around your cock and she still wanted more... Or that it would feel incredible! The sensations of it all stimulated the pleasure center as you tilt your head back with your eyes lightly closed. Unbeknownst to you, the nanobots responded to the stimuli of fucking the good doctor and released the pheromones, in response to the desire burning in you. Kara sexily strolled over to you, exaggerating her hips from side to side and walked in a straight line.

"Well... Maybe I could be your assistant. After all... I'm responsible for him, and I need him at his best." She purred heavily on the last word. She wrapped her arms around you, and you unconsciously take the reins in ramming in and out of Dr. Katari. Then was when Kara slipped down the top half of your uniform, roaming her hands along your chest and pectorals, especially. Then as you turn your head to one side, she nibbled on your exposed ear and tweaked your nipples. You moan softly as you tilt your head back on her shoulder, gradually speeding up in plowing Kitty's asshole. She was in bliss...

"Ohh! Oh, yes!" she moaned in-between pants. "Patient is performing--Unh!--as expected. Healthy as a horse..." she sighed, raising her ass up higher to give you easy access. You took that as a signal to go faster and harder, which you did, much to the doctor's incredulous pleasure. "Ahh! Ah, fuck, yeah! Pound me, baby! Pound me raw...!" And that just encouraged you to give it all you got! And Supergirl, not wishing to be outdone, took your hand and placed it between her legs and revealed a very damp spot.

"You like that...? Huh?" she goaded. "Pounding a doctor's tight ass...? Feeling your supervisor's wet pussy...?" As if you needed any more pushing to push on. You felt your climax fast approaching, and your fingers instinctively plunged in and out of Kara's sopping pussy. At that moment, you had brief flashes, visions of the women you've fucked since you joined the Justice League: Supergirl, Huntress, and Black Canary, for example. All of those memories, and subsequent sensations, piled on and made the pleasure more so than ever! You were going crazy, your moans becoming soft bellows as Kara scratched along his pectorals, until finally...

"I'm--I'm cumming! I'm cumming!" you warned, but 5 seconds later, you blast your white seed deep in Dr. Katari with a strained moan, while Supergirl bit the side of your neck as she orgasmed hard, drawing some blood in getting carried away. After that, you pull out of her ass with a quiet pop and slip out from between the girls. You pant heavily, and watch the doctor sit up tauntingly, puffing her chest out a bit.

"Well, I'd say that he passed his inspection with flying colors," she mused, gazing at Kara. "Wouldn't you?"

"But I can't say for sure. ... I haven't had my turn to 'examine' him." She then slipped off her short skirt and panties down to her knees, lifting one leg to slip them off a bit and then the other. She then stood before him with a smidgen of wetness dripping out of her. Your dick slowly got rock-hard again.
