Tell her what happened

"I know, Miss Henderson, but Bert did something to me."

She suddenly looks extremely serious. "What did he do?"

"He put something inside me; like inside my 'you know'. And now it's vibrating."

"May I check?"

Fuck yeah! "Yes, if you have to."

She pulls you in and discreetly touches your mound through the dress for a couple of moments. "There is something in there."

"I need to get it out!" Otherwise you'll be leaking fluid all over the dance floor.

She puts an arm around your shoulder and gently but quickly guides you to the staff bathroom. Once inside she locks the door.

"Okay, Ariana, this is going to get very... personal. Are you ready?"

What is she going to do? "Y-yes."

She quickly hikes your dress up to your waist and gathers it, flipping it over one of your shoulders. Then she takes you by the hips and hoists you up onto the counter by the sink. Finally she pushes you gently back and spreads your legs so that you're vagina is easily accessible. The device is already having a major effect as your natural juices are dribbling out.

She gives you a reassuring smile. "I guess we won't need lubricant. Now, you're going to feel a little push."

You gasp as two of her fingers penetrate you. This is something you'd only ever fantasized about. As she carefully feels around you struggle not to scream in passion. She seems to totally misread it.

"Don't worry, I won't be in here long."

"It's... it's... aaah... all right."

"No it's not alright; this is enough to have Bert charged with sexual ****."

"Not that... your fingers... s'okay... honest. Ohhh!"

"One request, Ariana; could you try not to be so vocal? These aren't the thickest walls, and people talk."

"I'll... uhhh... try..."

She has the vibrator pinned now, right against your G-spot. You **** your mouth closed so all that comes out is a whimper. Her fingers curl and her short nails drag across your most sensitive place, triggering an incredible orgasm. You twitch and buck from the sheer **** of it, but manage not to scream your pleasure.

"Down girl! It's nearly out."

She shows you the vibrator; it's a little bigger than a chewable vitamin pill and it's sitting in her fingers soaked in your fluid. She takes out a small baggie and drops the dripping and buzzing device in, along with a substantial quantity of your juice. After that she reaches into her purse with the other hand and takes out a cloth handkerchief. She wipes her wet fingers with it, then begins sopping up liquid on your skin and in the opening of your cunny. When she's done she folds up the wet cloth and puts it in a little pouch, which she then drops into her purse.

"Miss Henderson, why did you...?" You gesture around your crotch and then at her purse.
