M'gann had a lot to learn about humanity, specifically in what was frowned upon in its culture, such as her ability to read minds. When it came to her fellow Martians, the act of telepathic communication, sharing thoughts, ideas, and emotions was the norm, and not viewed as intrusive like it was on Earth. M'gann learned this early on from her friends, who were accepting of her use of telepathy, as long as she didn't cross any of their personal boundaries.
Now, M'gann knew that shapeshifting into her friend, Artemis, to have sex with her crush wasn't right...but at the moment, she was so turned on by what she had seen she didn't care.
"Artemis? I thought you were going to take a shower?" asked Dick Grayson, who was laying on his bed, wearing nothing but his boxers.
M'gann as "Artemis" responded to Dick's question with a sultry smile, and an even sexier response. Well, as sexy as she could imitating Artemis.
"I've still a little pent up, could you help tire me out, Dick? Just one more quick workout..."
She made sure to pout flirtatiously after she said this, holding her hands behind her back, and pushing her generous chest forward. M'gann was glad she could control her appearance, otherwise she'd appear a lot less confident as Artemis, and a lot more of a blushing mess, stammering mess. And how could she not? Dick had so much experience compared to her...
Dick snorted at M'gann's comment, raising an eyebrow but admiring her naked body all the same. Well, Artemis's naked body. M'gann briefly pushed down her jealous thoughts as Dick's boxer's pitched a large tent. If she wanted to seduce Dick as herself, she should have done so. But no, she needed him NOW...no waiting.
"And you called me a slut, huh...Alright, one last 'workout'--but don't make this too much of a regular thing, Artemis, or you might make Kory jealous!"
And with that, he embraced M'gann in a domineering kiss, engulfing her lips with his. Prepared for this, M'gann made sure to return the kiss the same way Artemis would, wrestling her tongue into his as she wrapped her hands onto Dick's handsome face, pulling him closer to her. Most importantly, M'gann pretended to act like she'd done this before, and that making out with Nightwing wasn't turning her "legs to jelly" as the humans would say.
"Mmmn! Mmn!" came the muffled moans of M'gann as she swapped spit with Dick, trying not to be too shocked when she felt Dick's clothed erection poke her naked thigh, or when Dick himself shamelessly squeezed her pale asscheeks. No, as "Artemis", she had already experienced these things.
M'gann herself hadn't. In fact, she had virtually no sexual experience at all before this moment. She was only a year younger than Dick by Earth's standards, twenty-one;though if her friends knew how old she was in Martian years, they'd joke about her being a "52-year old virgin."
She didn't have any shame in her inexperience--at least not at first, as it was never something she thought was too important to her--until today, when her desire, her long unrequited crush, Dick Grayson, was too much for her to resist.
"Oh, Dick, you're so eager..." cooed M'gann in Artemis's raspy voice as Dick kissed down her face, and suckled her neck briefly, inhaling her scent. "Ah, ah, ah...!" She gasped openly, breaking character when Dick licked at her nipples on her moderately-sized chest. Ironically, M'gann later reflected on the fact that her regular form had a naturally larger chest than Artemis did.
"OH! Ah, oooh..." She withheld her gasp as Dick went lower, burying his face in her--Artemis's--taunt stomach, mouthing and licking at her abs like they were the sweetest of nectars. M'gann clasped Dick's hair with Artemis's hands, caressing his jet-black hair with relish. M'gann thought she'd learnt all the fetishes from male humans at this point: breasts, cunts, asses, thighs, tongues; abs was a new one. It was unusual, but it didn't stop M'gann from yelping cutely as Dick made out with "Artemis's" athletic waist. All it did was make M'gann want to return the favor.
"Ha-ah!" She cried out in surprise as Dick slipped a few fingers into her clenching pussy, retrieving her wet arousal, and popping them into his mouth, tasting her juices right in front of her.
"Mmn...you're so wet for me...and ready."
He pressed her against the wall, squashing his chest to hers, spreading her thighs himself and aligning his huge cock with her small, juicy center. He grabbed one of her legs and placed it over his shoulder, stretching M'gann's muscles as far as she could, and then locked eyes with her.
M'gann breathed lightly, preparing to lose her virginity to him...in a way. Did it still count in a body that was already experienced? She hoped that he wouldn't notice the difference when he fucked her, and as tempting as it was to try to read Dick's mind, using her telepathy powers would cause her eyes to glow bright green.
His big cockhead plodded against tap M'gann's trembling pussy lips--before sliding itself inside, the first three inches of his man meat jammed inside the red-headed Martian all at once.
"OH FUCK!" cried out M'gann, using Artemis's raspy voice to drive Dick forward. She continued to use her dirty talk to keep him focused away from the fact that she was coming already. "SO GOOD! AH! KEEP FUCKING ME DICK! OOH! HARDER!"
In reality, M'gann wanted Dick to slow down and go easy on her--but as Artemis, what else could she ask for but wild and unrestrained sex?
"Still so tight!" groaned Dick, placing M'gann in a carry-fuck, her left leg flopping up and down on his strong shoulder. "Just as tight as before, I'm impressed--let's see how much you can take!"
Then he slammed M'gann against a nearby wall, fucking her so hard it was like he was trying to fuck her through the wall--which he technically could, if M'gann wasn't careful. She clawed at his pumping waist and hips, her mind racing to find a way to get Dick to cum, before he fucked her to unconsciousness.
"Mm! Mm! Mm! Just like that!" She squealed, brushing her face against the side of Dick's, and worming her tongue into his ear. All she could come up with was dialing up the amount of dirty talk, but all it seemed to do was cause Dick to viscously thrust into her, hissing his own dirty words into M'gann's ear.
"Damn, Artemis, can't handle me anymore? You've already cum three times around my cock...I guess this makes me the more experienced one, huh?"
His erotic taunts caused M'gann to bury her face in his clavicle in near-shame, responding to him with some low mewls. She didn't want him to see the look on her face...a look of embarrassment that didn't belong on Artemis's face at all. Artemis was always so confident and sexy in the way she was with Dick, and she had the fit, muscled body to back up her cocky attitude.
