Sylviaine's eyes widen in alarm at your words, her breath catching in her throat. She glances over at Celestia, their faces drawn and pale in the dim light of the chamber. The fear in her eyes is mirrored in her sister's as well.

"Wait," she says hesitantly, "you wouldn't really..." Her voice trails off, but you know what she's thinking: If there's even a chance that they could escape together...perhaps it's worth considering your offer.

Sylviaine takes a deep breath, her chest rising and falling rapidly. She steels herself against the turmoil of emotions churning inside her. "Very well," she says finally, her voice cold and controlled despite the tremor in her throat. "I accept your offer."

Her gaze meets yours directly for the first time since you brought them here, defiance etched into every line of her face. But beneath that mask of anger, there's a spark of desperation that you can't help but notice.

Celestia begins to move, setting a rhythm that rocks them both, her gaze locked on Sylvaine's face as it contorts with pleasure. She loses herself in the sensation, the sight of her sister writhing beneath her driving her higher and higher. Her own orgasm builds, a tidal wave gathering momentum.

As they climax together, their cries intertwine, filling the room as they collapse in a tangled heap.

Afterwards, Alex is released from his restraints, greeted by Celestia with a grateful smile.

Sylvaine smirks, crawling over to Alex and planting a gentle kiss on his lips before whispering, "We'll have to discuss those fantasies sometime, won't we?"

Celestia nods, her eyes softening with understanding. "Of course, Alex. We're here for you."

Together, the three share a tender moment, basking in the afterglow of their shared pleasure before the reality of the world outside their little sanctuary begins to intrude once more.
