"But-" Kara began.
"No buts. Bend over and do as you're told, or we can stop right now." Lena threatened.
There was a brief pause, then Kara pouted, "Yes Ms Luthor."
"Good girl." Lena beamed, pressing her lips to Kara's, and then informing her, "I'm in charge here, Supergirl. Luckily for you, I have a good way to remind you of that."
With that Lena took out the strap-on dildo she had hidden in her side draw, causing Kara's eyes to light up. It was something that they had become very familiar with, and Lena just couldn't let this wonderful opportunity go by without bending Supergirl over her desk and giving her a nice, good pounding. Of course while Kara had superhuman stamina Lena didn't, so she took her time equipping the toy as sensually as possible as an excuse to give herself time to recover.
And for Kara to get into position, which required one more look to do so. Then she gently pushed that little red skirt up around Kara's waist and those panties down around Kara's knees before Lena took a firm hold of her newly acquired cock and guided it to Supergirl's pussy.
Kara let out a loud gasp, followed by a long moan as the head of Lena's cock entered her pussy nice and slowly, the rest of the shaft following just as slowly and gently. Not because Kara couldn't take a faster penetration, because she could, especially after being so skilfully fingered to orgasm, making her pussy nice and relaxed, and extremely wet.
No, this was about both women savouring this wonderful act, Kara obviously getting the best of it because Lena couldn't feel it like a guy would. Although that would be hard to argue, given the look of glee on Lena's face as she took Supergirl's pussy and slowly filled it with her strap-on cock. More accurately, as a Luthor slowly filled it with her strap-on cock.
It was wrong of Kara to reduce Lena to simply her family's last name, when she wasn't anything like the other monsters in her family, but in moments like this she just couldn't help it. Plus Lena was kind of encouraging it with her assistance on Kara calling her Ms Luthor, making it clear that they were both focusing on the same thing, namely the fact that a Luthor was so totally dominating a Super.
Well, also Lena was in a position of authority, and as always Kara was willingly subservient to her. And it was kind of hard for Kara to tell which she loved more, especially during the wonderful moment that Lena's thighs came to rest against her cheeks, announcing every inch of that strap-on was buried within her pussy.
For a few long minutes Lena allowed them both to savour that fact before she began slowly pulling her hips back, causing inch after inch of dick to slide out of Kara's twat, causing her to whimper at the loss. Of course those inches were soon return to her, causing her to moan with joy, especially as the process was repeated, Ms Luthor officially beginning to fuck her with her big cock.
Oh yes, Kara's wonderful girlfriend Lena Luthor was fucking her pussy with her big strap-on cock, while she was bent over her desk like a slutty secretary. Supergirl! Supergirl, her alter ego of truth, justice and female empowerment which Kara had worked so hard to create was now bent over and being fucked like a little slut.
Of course there was nothing wrong with enjoying this act, but slut shaming herself was just heightening Kara's enjoyment. Just like looking back over her shoulder and seeing the look of delight on Ms Luthor's face, but more importantly the proud look of dominance and control when compared to the submission and sluttiness Kara was feeling. Then just when Kara didn't think it could get any better, it did.
Which of course was a foolish thing to think, because of course it would get better, but Kara hadn't expected it to be this soon. Although she was glad for it, not just because they were in public which should mean this should be a quickie, but because this meant they were clearly about to do her favourite thing ever, which should really make her feel like the slut she was currently being.
Lena loved to take another woman like this. It was so primal, and wicked. Making them bend over for her. To get on all fours, or bend over a desk like a little bitch. To bend over her desk like a little slutty assistant. God, she used to think it couldn't get better than this, but then she had been introduced to the indescribable joy of doing this to the mighty Supergirl, and Lena just didn't think she could go back to doing this to just any girl.
It just wouldn't be the same. No, it just wouldn't give her the same thrill as bending Supergirl over and shoving her tongue, fingers or a toy inside her and fucking her until the infamous Supergirl was cumming like a hot little slut for her.
Although the best thing about it was that this wasn't just Supergirl. No, this was Kara Danvers, the woman who had once been the best friend she'd ever had, and was now easily the best girlfriend she'd ever had.
Oh yes, as much as Lena had desperately wanted to ask Kara out that first day she wandered into her office in that cute little disguise of hers, she and her cousin pretending to be simple reporters, she was so glad she had chickened out, because it allowed a bond to form between them which made moments like this so much more intense and intimate.
Which was why under normal circumstances Lena could draw this out for hours, but just in case she decided to speed things up a bit. Besides, when her beautiful Kara was in this position it was hard to resist doing this next thing for long.
Namely sticking her finger into her mouth and sucking on it for a few long seconds, and then pressing it against Kara's ass hole. Lena made sure to spread both butt cheeks so she could get the best possible look of her finger violating that tight little back door, both women crying out joyfully as they both savoured the feeling of Kara being anally penetrated.
Something they both always loved, but maybe especially in moments like this when Lena could feel her dildo gently pumping in and out of Kara's cunt, a feeling she was sure felt even more intense for her girlfriend, especially given the wonderful sounds she made throughout the additional penetration. And as Lena began to fuck both of her fuck holes at the same time.
Of course Lena did pause the thrusting of her hips once the finger was buried inside Kara's butt so she could savour the moment, and make it easier on her girlfriend. Which of course only made her girlfriend whimper in disappointment, as this was no ordinary girl, but the mighty Supergirl, who could easily take much rougher treatment than this.
She wasn't going to get it, not yet, but Lena did start gleefully fucking her in both of her holes, making her hot little girlfriend squirm with delight, and cry out joyfully for more. Lena was only too happy to give it to her, provided that she asked properly of course, and as Kara couldn't seem to initially find the words she just kept gently pumping her pussy and ass with her cock and finger.
"Lena! Please!" Kara whined, before crying out as she was spanked with Lena's free hand.
"Ms Luthor." Lena reminded her.
"Please Ms Luthor, fuck me!" Kara quickly corrected herself, "Mmmmmm, fuck me harder! Fuck me in both my holes like the little slut I am! Fuck me like you fuck your girlfriend! Ohhhhhhh yessssssss, fuck me and make me cum like your slutty little girlfriend, oooooooh, that loves you so much. So much that she wants you to fuck me and make me cum, ooooooohhhhhhhh, just like you effortlessly do to her."
Lena was delighted by her girlfriend's teasing, although Kara should know when it came to teasing, she was out of her league, "Well, you are almost as tight as my girlfriend..."
Kara tried to hold back for a few long seconds, then she burst out into a fit of giggles and scolded, "Lena!"
"Ms Luthor!" Lena reminded with another hard strike, before almost casually murmuring, "But... are you as big a slut as she is. Huh? Do you like it up the butt? Mmmmmm yesssssss, does Supergirl want to prove she's just like my girlfriend by letting me fuck her nice and hard in the ass, while she's bent over my desk? Because then I would definitely reward you with an orgasm for being such a good little slut for me."
