Play with her Toy.

Miranda stepped back, her eyes never leaving Shepard's. "Jack's not here, but I think I know what she had in mind," she said, a knowing look in her eyes. She reached behind her, pulling out a bottle of lubricant from a nearby drawer. "You're going to be mine for the next few hours. And we're going to explore just how much you can handle."

The cold liquid squirted onto Shepard's skin, making her jump. Miranda chuckled, the sound dark and seductive. "Don't worry," she cooed, her hand slipping between Shepard's legs. "I'll make sure it's a very merry Christmas indeed."

The coolness of the lube was a stark contrast to the heat of Shepard's arousal, which was now pooling around the base of the plug. Miranda's fingers danced around the edges before finally sliding over her clit, eliciting a strangled cry from the bound woman. Shepard's body tensed, her hips bucking involuntarily as Miranda applied gentle pressure. The plug inside her felt impossibly large, stretching her with every movement.

Miranda stepped back again, a wicked gleam in her eye. "Let's not rush things," she murmured, her voice a seductive purr. She reached up and unbuttoned her own uniform shirt, revealing the black lace bra beneath. She let the fabric fall to the floor, and Shepard couldn't help but stare at the perfection of Miranda's body. Her breasts were full and firm, her stomach flat and toned, a testament to the hours she spent in the gym.

The sight of Miranda undressing before her only served to increase Shepard's arousal, and she could feel the plug inside her moving with her every breath. "Fuck," she cursed, her eyes never leaving the other woman's.

Miranda took her time, her movements deliberate and tantalizing as she slid her bra straps down her shoulders, revealing her own arousal. Her nipples were hard and pink, pointing straight at Shepard like twin accusations. "I've always wondered," she said, her voice a sultry whisper, "what it would be like to have you at my mercy."

Her hands slid down to the waistband of her pants, and she began to undo them, the sound of the zipper echoing through the room. Shepard's eyes followed her every move, her body taut with anticipation. The plug inside her was a constant presence, a silent reminder of her predicament.

Miranda stepped out of her pants, revealing matching black lace panties that left little to the imagination. She stepped closer, her hand sliding over Shepard's hip, her fingers tracing the line of the plug's base before dipping lower to glide over her wetness. Shepard's breath caught in her throat, and she closed her eyes, trying to regain some semblance of control.

"Tell me Shepard. How did Jack get you like this?" She whispered in her ear.

Her voice was a siren's call, and Shepard felt her resolve waver. "It's...complicated," she managed to say, her breath ragged.

Miranda's hand slid down further, her fingers slipping easily into the wetness between Shepard's thighs. "I'm sure it is," she murmured, her eyes never leaving Shepard's face. "But I want to know everything."

The music grew louder, the beat matching the rhythm of Miranda's strokes as she teased the edges of the plug. Shepard's knees buckled slightly, and she had to brace herself against the wall to stay upright. "Jack...she said it was a surprise," she panted, her eyes squeezed shut as the sensations grew more intense.

"You usually get tied up naked with a plug up your ass fir surprises?" Miranda teased.

Her voice was a velvet caress in the cacophony of the room, the bassline of the music seeming to pulse with the rhythm of Shepard's racing heart. "No," she gritted out, trying to hold onto the last shreds of her dignity. "But with Jack, you never know what to expect."

"Details Shepard." Miranda ordered. "Or you won't cum at all tonight."

The threat was clear and it sent a shiver of fear and excitement through Shepard. She took a deep breath, her chest heaving with anticipation. "She slipped it in while I was sleeping," she finally confessed, her cheeks burning with a mix of embarrassment and arousal. "I woke up like this."

Miranda's eyes glinted with amusement. "How...considerate of her," she said, her voice dripping with sarcasm. Her fingers continued their slow, torturous dance around the plug, never quite entering Shepard but always so close that she could feel the promise of relief. "But I suppose we should get you ready for the main event."
