Send her back to work

You hold her shoulders and straighten her up. She looks wild and frightened and you thumb the remote again, triggering a brief burst of vibration in her ass. She gasps and staggers again, gasping and biting her lip.

"What are you doing to me Sir," she moans, her eyes begging you.

"Continuing your training, wench." She gives a little wiggle as she hears that word, a smile fighting through the worry on her face.

"Thank you Sir. It's just that I've never had anything up...there. I don't know if I can walk with it in." You send another burst of vibration through her and she groans, her mouth open wide, her knees wobbling. It takes her a moment to regain some composure.

"How long must I keep it in Sir?"

"Until I allow you to take it out. Now get back to work."

"Yes Sir," she says meekly, backing towards your door. You let her get her hand on the knob then press the remote again, letting the vibration run for ten seconds. She gasps, clinging to the door knob, almost falling to her knees.

"Oh God, Sir! It's too much, please stop," she begs. You silently gesture her out of your office.
