I have brought with me a (brand new) remote vibrator. You go to the bathroom and put it on and then come back to the table where we are sat. I have the remote control and am in control and i can sit and watch you squirm as you enjoy a discreet but public orgasm as we chat.
I've done that!
Back in '04, IIRC, at the Skin Two Expo in the Barbican Exhibition Centre
I went with 6 or 8 friends, but prior to going, Master R thought it would be interesting to insert an
E-Stim up my backside!
(I have a very pervy history!)
Anyway, six of us went to the event, and the remote control was passed from person to person.
The remote enabled the holder to alter the wave pattern and intensity.
Anyway, a loose wire / connection resulted in the remote only having an intermittent effect,
so one person, figuring nothing was happening, held down the intensity button. A second later
the wire connected and a powerful series of jolts hit my body
and I hit the roof in shock.
In the middle of a crowd of curious onlookers.
Being a pervy type Expo, a lot of them guessed what was going on and giggles all round.
Hummmm....
These days I prefer a cuppa in my local cafe.
