Felicity Smoak had spent the past five years searching for people looking shifty, and she felt she got pretty good at it. At least, when it came to searching for them on her computer screen.
She was a lot less aware of her surroundings, especially when she was sat at the aforementioned computer searching for super villains, like that bitch Black Siren who had humiliated her a few weeks ago, but had somehow disappeared from her raider ever since. She wanted her revenge on her, which was one of the reason she didn't notice Thea Queen hanging around Arrow HQ trying to work up the nerve to talk to her. Not until Thea finally worked up the courage to get her attention.
"Erm, Felicity." Thea squeaked softly, and then when that didn't do the trick she took a deep calming breath and then spoke louder, "Felicity!"
"What?" Felicity startled, turning around in her swivel chair and then finally seeing how nervous Thea looked, "Thea, what's wrong? You don't look so good."
Ignoring the question Thea stammered, "I, I... I have a message for you from our Mistress."
"What?" Felicity frowned in confusion.
"Mistress Laurel." Thea hissed in explanation, and then when that clearly wasn't enough added, "Black Siren!"
"Oh!" Felicity's eyes went wide in recollection, then in horror, "Oh God!"
Then Felicity repeated these words over and over again as Thea slowly turned her back on her, undid her pants and pulled them down, at which point the words got a lot more high-pitched and Felicity almost fell out of her chair. Why? Because Thea pulled down her pants and revealed she was not wearing any underwear, and her ass hole was gaping wide open.
To make matters worse Thea spread her cheeks to make that gape look even more obscenely wide. Which was so gross, but Felicity found she just couldn't look away as she was really utterly dumbstruck by Black Siren's message, which would have been pretty clear even if Thea hadn't said anything.
"You're next." Thea said softly, her words sounding deafening in the large, quiet room, "She's going to strap on a big dick, tear your ass hole apart and make you love it. She's going to ass fuck you until you cum harder than ever before. Then she is going to completely wreck your ass until you're her mindless fuck pet."
"Wow..." Felicity murmured, still staring deep into Thea's rectum as she found herself quipping, "You're next, would have probably sufficed."
"I know." Thea blushed, quickly pulling up her pants, "But she was very clear."
"And you do as she says?" Felicity question softly.
Blushing even more Thea quickly finished doing up her pants, then forced herself to turn around to answer, "I, I can't help it. You don't know what it's like. She just, she just makes me cum so hard. And, and... I know it's not Laurel, not really, but it's close enough."
There was a pause and then Felicity admitted without looking at the other girl, "I know better than you think."
This caused Thea to tilt her head and frown, "Were you in love with our Laurel too?"
"No!" Felicity protested unconvincingly, before admitting, "Maybe a little. Which Black Siren used against me when we had her locked up here... but she didn't, erm..."
"Fuck you up the ass?" Thea grinned knowingly, and then when Felicity gave her an apprehensive look Thea added, "Don't worry, she will. She's impossible to say no too. Then you'll feel differently."
"I doubt it." Felicity grumbled.
"You will." Thea said confidently, and a little sadly. She then turned to leave, before thinking better of it, "Oh, and please don't tell Oliver."
"Are you asking, or as she?" Felicity questioned.
"I am." Thea said firmly, before chuckling, "I don't think she believes you have the guts to tell Oli what I just did."
"That's accurate." Felicity admitted, "But I could leave out the nature of the threat and stick with one of the boys, or I could hideout down here for a while."
"And if that's what you really want, go for it." Thea encourage softly, "I'm not sure she cares, but I do, and I don't want you to do anything you don't really want too. But, if you let her fuck you once, it's probably because deep down you wanted it. I don't think she would have gone through with it if you had really protested. Or maybe that's just wishful thinking. Either way I hope you let her fuck your ass, because seriously Felicity, there's nothing like it. Trust me, I know."
For a few long seconds Felicity just watched Thea walk away, then she called after her, "So what? You're working for her now?"
"No." Thea admitted, "I'm just her little anal whore. And soon, you will be too."

After that Thea had left her alone, but their conversation echoed in Felicity's mind the rest of the day. Especially the part where Thea had exposed herself like that, the memory of her friend's gaping butt hole on her mind more than anything else, Felicity terrified and yet somehow excited over the idea that she could suffer the same fate. If that wasn't bad enough Thea started sending her photos of herself being used by 'their Mistress'.
One of Thea's ass bright red, obviously fresh from a spanking, one of her with her face buried in between a woman's legs, presumably Siren's, and another with her sucking a strap-on. But the one Felicity found herself lingering on was presumably Thea bent over, her ass hole stretched obscenely wide around a strap-on, and to a lesser extent her friend sucking what appeared to be that strap-on after it had been deep within her bottom.
Some of those pictures had come with taunting messages, and sometimes there was just messages with graphic detail about what was going to happen to her, which Felicity assumed was probably written by Black Siren herself, although she wasn't sure if that made it worse.
Of course she should have told someone, anyone, about this all, both so Thea could get help and they both could be protected from the murderous psychopath who had taken such a perverted interest in them. But she didn't. No, she kept her mouth shut, and was punished for it when she returned home to find Black Siren casually waiting for her, the bitch slowly finishing off some expensive wine Felicity had been saving for a special occasion, and looking as hot as hell doing it.
"Hello lover." Black Siren purred with a wicked grin, "Did you like my messages?"
"I... I..." Felicity stammered, blushing furiously.
"I know, I know, sending Thea would have probably been enough, but I just got so bored waiting here for you, and I just couldn't stop thinking about all the fun we're going to have." Black Siren confessed, "Especially after I called my favourite little anal whore, and spend the most of the afternoon playing with her."
"Drink?" Thea asked nervously, suddenly coming around the corner holding a tray with another glass of wine, and not wearing a stitch of clothing.
"Thea!" Felicity gasped, unable to stop her eyes wandering down to admire her friend's body, most notably at that moment her perky little tits.
