Take Rosaria's gag off so that you can at least talk to her.

You cross to Rosaria in three strides, your hands already reaching for the leather strap behind her head. She stiffens as you touch her, then sags forward against you with a muffled sound of relief.

"Hold still," you murmur, working at the buckle. It's stiff - new leather - and your fingers fumble with the tongue. Rosaria's breathing is ragged against your shoulder, her hips still making those small, helpless movements. The vibrator hums between you like a third presence in the room.

The buckle releases. You ease the ball from between her teeth and Rosaria gasps, working her jaw, her tongue darting over her lips.

"Matteo," she says, and her voice is hoarse and cracking. "Matteo, what the fuck - what the actual fuck is -" She stops. Swallows. Her eyes are wet. "There's something inside me. There's something vibrating inside me and I can't - I've been trying not to - Madonna santa, it won't stop -"

Her knees buckle slightly and you catch her, your arms wrapping around her waist. The belt underneath her dress is solid, hard metal. You can feel the faint buzz against your palms.

"I know," you say, helpless. "I know, it's controlled by an app on my phone and they took my phone and -"

"Get it off." Her voice cracks into something higher. "Matteo, please, get it off me, I can't -" She presses her face into your neck and her whole body shudders. "It's been an hour, maybe more, I don't know, and I keep almost - I keep getting close and it's not enough and I can't -"

She makes a sound that's half sob, half moan, her hips grinding against you reflexively. You feel heat flood through you - guilt and arousal tangled so tightly you can't separate them.

"I can't," you say, and the words taste like ash. "Not until tomorrow. They have my phone."

Rosaria pulls back, staring at you. Her pupils are blown wide, her lips swollen from the gag. "Tomorrow?" she whispers. "24 hours of this?!"

Mikaere clears his throat gently from the doorway. "If I may, Sir - the belt's low setting is designed for extended wear. Many couples find it enhances intimacy. There are other ways to provide relief, of course."

Rosaria's head snaps toward him. "You," she hisses, and there's the woman who bit the customs officer. "You smiling bastard, you -"

"Rosaria," you say, catching her shoulders. She's trembling.

Mikaere remains serene. "Shall I leave you to settle in, Sir? Dinner service begins at six."

"You can bring your slave with you", he adds, after a moment. "The main restaurant has tethering posts at every table."
