Nyssa al Ghul would truly do anything for her beloved Sara Lance. Her father called it a weakness, and that ultimately it would be her downfall, and deep down she knew he was right, but they could have never exactly guessed what fate would befall on her. If she had known it, and what exactly was going to happen to her tonight, she would have stayed far away, but what could she do when her Sara called, but come running?
Although the location was somewhat strange, given that it was the apartment of Sara's dead sister Laurel Lance. Yes, their mutual friend Thea Queen was now living here, but surely there were less troubling locations? So Nyssa was cautious as she approached, and then got quite the surprise when Thea answered the door completely naked.
"Hey Nyssa." Thea beamed, giving her friend a moment to admire her body, "Come in, the Mistress is expecting you."
Then Thea turned and walked into the apartment, leaving Nyssa to follow and close the door behind her, and she did without question, staring at the small girl's amazing body the entire time. Nyssa's training held firm, glancing around to ascertain if there were any threats that she could sense, but her main attention remained on that perfect little body.
For someone so small Thea had nice perky pair of tits, and quite a nice well-rounded booty which Nyssa always thought was begging to be fucked, but now especially that a butt-plug was currently buried in between Thea's ass cheeks. Was this why Sara had called her? To share this beautiful little slut? Thea hadn't been in control of her own actions when she killed Sara, but Nyssa would gladly help her beloved Sara takes some unnecessary revenge if it meant a night of using Thea Queen as their personal lesbian sex slave.
Sadly it quickly became apparent that Sara wasn't the one that had turned Thea into her sex slave, given her Sara was tied to a chair, with a ball gag firmly in her mouth, which should have been the most shocking thing about this whole situation, but it wasn't. No, that was the fact that in a chair next to her sat Sara's dead sister. Or perhaps someone in a very convincing disguise?
Because she looked exactly like Laurel Lance, but... there was just something about the way she smirked at her which told Nyssa this was someone else entirely. Also the fact that she was wearing an outfit which looked like it was straight off a BDSM website, and that little Thea came to kneel beside her, along with Felicity Smoak and some other girl that Nyssa didn't recognise.
The Laurel lookalike then spoke, "Nyssa al Ghul, so glad you could join us. I wasn't sure you would, but apparently my pets are right, you really are whipped for your precious Sara."
"Who are you?" Nyssa glared.
"Black Siren." Black Siren introduced herself, and then when the assassin gave her a look she elaborated, "I'm the Laurel Lance of another universe, but you can call me Black Siren for now, mmmmmmm, and soon Mistress Laurel."
"I see." Nyssa said disappointedly.
Which caused Black Siren to smirk, "You hoped I was your Laurel, resurrected?"
"No." Nyssa confessed, further explaining herself, "The Laurel Lance of this world is at peace. I would not wish the agony Sara went through upon her."
"And yet, you are disappointed?" Black Siren pointed out.
"On the contrary, if you had been Sara's sister, it would have complicate things. Now? I have no reason not to kill you." Nyssa threatened.
"I wouldn't be so sure about that..." Black Siren smirked, unfazed by that response, "You haven't heard my offer yet."
"Offer?" Nyssa scoffed, "Are you going to beg for your life?"
"Why would I? As you can see, Sara is fine, and so is all her little friends." Black Siren pointed out, "I've just been giving them an education in their place in the world. An education I wish to give you."
"And why would I ever agree to that?" Nyssa responded with a rare laugh.
"Because if I failed to break you like my other pets, you get something you've clearly wanted for a long time." Black Siren announced, slowly getting to her feet and walking over to her pray, "The permission to do whatever you want to this beautiful little body of mine. For you to fuck me... to fuck Laurel Lance, however you want. To make Laurel Lance eat your pussy. To fuck her up the ass. DP her. Whatever you want."
There was a long pause, then Nyssa softly pointed out, "You're not Laurel Lance. Not our Laurel Lance."
"No." Black Siren agreed, "But I'm close enough for you to live out your most twisted fantasies."
Another pause, then Nyssa half-heartedly protested, "I don't have any twisted fantasies about my lover's sister."
"Oh? And here I thought assassins were supposed to be good liars?" Black Siren teased, moving over to her sister's mirror image, "If it helps, Sara was just as convincing. Mmmmmmm yeahhhhhhhhh, she could barely offer up any protest, before she was burying her face in my pussy and eating it for all she was worth. Oh and her ass, ohhhhhhhhh, that was so fucking tight! God, how had she gone so long without an ass fucking? It's a God damn crime. You should be ashamed of yourself. All of you, should be ashamed of yourself for not regularly fucking an ass this sweet. But that's okay, mmmmmmm, because it's mine now, and I promise, I'll take good care of it. Mmmmmmm yesssssssss, there's a vibrating butt-plug up there now, keeping Sara's bitch hole nice and ready for me to fuck again, and again, and again, whenever I want."
