And maaaaybe you want to hear out what their plan is.

About as soon as you're taken to your destination - by your guess, some sort of performance practice space - you're shoved against a radiator as Gracie pulls out some rough-looking red string. With a smooth, deft hand she binds each of your wrists on the radiator, leaving you unable to escape, even if you wanted to. Typically, the thing isn't even turned on, so it doesn't offer you the comfort of warmth. Only the cold sting at the base of your hands and the back of your legs.

Legs that suddenly become more exposed, as now that her hands are free, Lacie relieves you of your skirt in a single sweeping motion. And right after her sister has done that, Gracie yanks down your panties, allowing your erection to finally spring free. It stands out - not as much as you're sure other girls' would, but it stands out nonetheless - bobbing just a little in the open air as your breath grows heavier.

"Ooh, look at this, Lacie~ She's so hard already! She's even dripping pre-cum all over the floor! I wonder what she'd like us to do for her? I guess she'd like us to make her explode, give her what she's so badly aching for. Buuut, she didn't consider one thing! She's all tied up, and she can't touch herself. So you know what that means, right, Lacie?"

Lacie pushes you back, her forearm pressing across your collarbone, just as a show of ****. "We decide when you come."

"That's right, dear sister! And since we decide when you come... might as well have a little bit of fun with you!" Gracie pats her sister on the shoulder, her face pinkening the tiniest bit as she comes up with a new devious scheme. "Right, Lacie! It's time. Code Green."

She seems to understand instantly, as the two siblings get in position... then Lacie's expression changes to be the same as Gracie's, and they both give you a sultry wink as they tug at their blazers.
