I love playing with my favorite subgirl, she cums at the drop of a hat. I secure her to the inverter, place headphones over her ears and blindfold her, then upside down so I can access her pussy with my toy. With no distractions all she concentrates on is the pleasure of the vibrator going in and out of her, knowing that her Mistress is administering the pleasure, and before you know it she is having a very loud orgasm.
