The effect is immediate. Her eyes widen in an expression similar to fear, before swiftly rolling back in her head. Her back snaps up from the table in an arch, and the bonds holding her limbs in place creak and strain against her. she remains frozen in that position for some time, nearly three minutes by your count, before she collapses back down against the table. She does not lie still, however, as she is nearly immediately overcome by a sort of shivering, jerky motion, with legs and arms spasming at seemingly random times. She makes a sound somewhere between a cry of pleasure and a sob, and shudders violently once more.

She looks rather pathetic. You contemplate showing her mercy. You didn't know just how powerfully the collar would affect her, and you didn't expect her to break so easily. You could give her a rest, even if only for a moment.
