Time for Mark to Meet Sienna

As Mark steps into my lair, a place he's never been before, I can see the curiosity light up his eyes. I greet him with a kiss, one that's more for him than for me, but it doesn't feel wrong. Not anymore. My hands roam over his back, pulling him close because he wants it, and I'm here to please.

Sienna's standing off to the side, her arms crossed, her face a mask of anger and betrayal. She starts to lay into him, spewing accusations about manipulation and ****. But with a sharp "Shut up, Sienna," her rant cuts off mid-sentence, and she falls silent, head bowed obediently. She's under the ray's influence now, compelled to obey me, to want what I want.

I turn to Mark, my gaze apologetic. "This wasn't the plan. I wanted to make her yours, but it didn't work out that way."

He mulls over the situation, running a hand through his hair. "So, she's still going to do what you want, even knowing that you're doing what I want?"

"Exactly," I confirm, and I can see him relax a little at that.

His eyes slide over to Sienna, who's watching us with a mix of disgust and resignation. As Mark approaches, she tenses, her frown deepening. He pauses before her and says, "Get naked."

Sienna's refusal is immediate, her voice laced with anger. But I'm here to give Mark what he wants, and if it's Sienna's compliance he desires, then that's what he'll get. "Sienna, do as he says," I command, my voice firm.

Her face is a storm of fury, but she can't resist the order. She strips, her movements sharp and ****. Her clothes fall to the floor, revealing the pale skin and fiery curls that cascade down her back. Her breasts are full, her nipples hard with either anger or arousal, maybe both. Her curves are more pronounced in the light, her hips leading down to long legs and a neatly trimmed pubic mound. She stands there, exposed and fuming, yet there's a glimmer of something else in her eyes—a hint of the obedience that's been **** upon her.

Mark's gaze lingers on Sienna's naked form, and I can tell he's more than just admiring her. He turns back to me, a question in his eye. "Maybe you should explain to her what you want now."

I understand what he's getting at and can't help but smirk, already a step ahead. I walk over to Sienna, taking my time to appreciate the curves and valleys of her body. I'm not into Mark, but Sienna? She's always been able to stir something fierce within me. And I can't help but hope Mark's into the idea of a threesome.

"Sienna," I start, my tone gentle but firm, "I want to serve Mark, to be whatever he wants, and to protect him from any threat. And maybe, if he's into it, for you to join in on the fun."

Sienna's eyes, a mix of anger and confusion, search my face, but as my words sink in, I watch her body relax. "If you want to please and serve Mark, then I want to help you do it," she says, her voice softening.

She lets out a resigned sigh, a glint of her old humor flickering to life. "Well, if Mark's game, I sure wouldn't mind joining in. I am bi, after all. Might even enjoy it more than you."

Mark's arms are folded as he watches Sienna, and I can tell he's trying to piece together the situation. "Does anyone else know about… this?" he gestures vaguely, his eyes flicking between Sienna and me.

Sienna shifts, her nakedness almost forgotten in the gravity of the moment. She's less hesitant than before, probably because she knows I want to please Mark, and because I've told her to obey him. "I… I may have mentioned to Clonica that Kat could be compromised," she admits, her voice steadier than I expected. "Wasn't specific, though. Just that she might have been hit by a mind-control ray. I was supposed to get back to her with more info."

I feel a twinge of concern at the mention of my fellow colleague and super friend. "We should probably make sure Clonica is on our side then," I warn Mark. "She's part of a big league of supers, and if word gets out…"

Sienna can't help herself, a joke slipping out despite everything. "Mark might enjoy fucking Clonica and all her clones, though," she says, her sarcasm tinged with a hint of seriousness. "Imagine the possibilities…"

I can feel my cheeks heat up with excitement at the thought, and I'm not ashamed to admit it. "I wouldn't mind being a part of that," I say, a little breathless.

Sienna looks at me, a slow smile spreading across her face. "Neither would I, honestly."

Mark rubs his chin, clearly conflicted. "Using the ray on someone else again… I don't know." But there's a gleam in his eyes as he imagines it—Sienna, Clonica, her clones, and me. "But I can't say the idea doesn't have its… appeal."

Sienna nods, her determination cutting through the tension in the air. "I'll contact Clonica and set up a meeting here," she says, her voice steadier now, a testament to her resolve. "All you have to do is stay hidden with the ray, hit her as she comes in, and make sure Mark is the first person she sees after that. If we play this right, I don't expect any problems."

I give her a sharp nod of approval. I can't help but let my gaze linger on her body; her curves are even more enticing when she's standing there, so defiant yet so under my influence. She catches me staring and quirks a brow, a playful smirk on her lips. "Is there something you want from me, Kat?"

Her question hangs in the air, and Mark lets out a low chuckle. "What is it that you want from Sienna?" he asks, his tone laced with amusement.

For a moment, I'm caught off guard, unsure. I'm supposed to want what Mark wants, but he's giving me the reins. "Well," I say, my voice thick with a newfound authority, "I wouldn't mind seeing Sienna on her knees, her head between my legs. Usually, she's the one calling the shots, but I'd be lying if I said I didn't want to flip the script."

Sienna's eyes glint with a mix of surprise and eagerness. "I'm more than receptive to that idea," she responds, her voice a sultry purr.

Mark leans back against a console, his interest clearly piqued. "Then by all means, proceed. Just make sure I have a good view." His words send a thrill through me, and I'm ready to take full advantage of this unexpected turn of events.

I watch Sienna, her bare skin glowing in the dim light of the lair, and I can feel the electricity crackling at my fingertips. She's always been a **** to reckon with, but now, she's mine to command. As I approach her, I see the hunger in her eyes—the desire to please me, to do whatever I want, much like my own need to serve Mark.

"Get on your knees," I command, my voice laced with authority. With a quick, obedient nod, Sienna sinks to the floor before me. I can't help but shift forms, my clothes melting away and my body responding to the pleasure of control and the anticipation of what's to come. My breasts swell slightly larger, my hips widen, and my thighs become even more toned, a physical manifestation of my arousal.

As Sienna's mouth finds my wetness, I throw my head back, moaning at the contact. Her tongue is eager and skilled, swirling around my clit with a fervor that sends jolts of pleasure through my body. I glance over at Mark, who's settled into a chair, his hand wrapped around his hardening cock, and I know I have to put on a show for him.

"Yes, just like that," I groan, as Sienna's lips envelop me, sucking gently. I can feel my form flicker and shift with each wave of ecstasy—my hair growing longer and then shortening, my skin taking on a golden sheen before returning to its sun-kissed hue. All the while, I maintain my focus on Mark, watching him stroke himself, a grin spreading across his face.

"Fuck, that's it, Sienna," I pant, my hands finding her head, guiding her movements to match the rhythm that I crave. Her submission to my will, her desire to please me—it's intoxicating, and I can feel the climax building within me, a storm ready to break.

As the waves of ecstasy crash through me, my form flickers uncontrollably, echoing the intensity of my climax. My body shifts like the surface of a pond caught in a storm, my breasts swelling and shrinking, my hips widening then narrowing, my face cycling through expressions of pleasure. I ride out the orgasm, each shift bringing a fresh wave until I finally steady, panting and spent.

Looking up, I catch Mark's smirk, his hand moving steadily over his cock. "Need any help with that?" I tease, my voice husky from my exertions.

He nods, the corners of his mouth quirking up further. I start to move towards him, but then I pause, glancing back at Sienna. "Actually, Mark, do you want her to take care of you?" My voice is thick with suggestion and newfound power.

His eyes glint with approval, and he confirms, "Yeah, I'd like that."

Turning to Sienna, I command with a wicked pleasure, "Suck his cock, Sienna." She doesn't hesitate, moving towards Mark with a readiness that belies her earlier ****. Kneeling before him, she takes his length into her mouth, her eyes locked on mine. She's not enjoying this as much as she did with me, that much is clear, but the desire to please me overrides everything else.

Mark groans as Sienna works him, her mouth warm and inviting. She's good at this, her tongue swirling around the head, her lips tight as she takes him deeper. I watch, a thrill running through me at the sight. Mark's breath hitches, his hips bucking slightly into her mouth, and I know he's close. With a final, deep suck, he comes, his seed spilling into Sienna's mouth. She swallows it down, meeting my gaze with a mix of defiance and submission.

Mark leans back, a self-satisfied smirk playing on his lips. "This is going to be a hell of a lot of fun, owning you both," he says with a chuckle, his eyes roaming over Sienna and me.

Sienna's quick to correct him, her tone firm yet resigned. "You don't own me, Kat does."

I can't help but let out a laugh at Sienna's defiance. Stepping behind her, I wrap an arm around her waist and pull her back against me. "Actually, sweetheart," I whisper into her ear, "Mark owns you. Because what's mine is his."

Sienna lets out a long sigh, her body relaxing against mine as she accepts the new reality. "Fine," she mutters, and I can feel Mark's eyes on us, taking in the sight with glee.
