Do you have sex toys?
Take the egg out of your pussy ... take the gag out of your mouth
Put the egg into your mouth ... taste yourself
Reach your hand into your panties ... play with your clit ever so gently as you watch

Imagine you are strapped down onto it - your mistress rides your face as you get well and truly fucked...
Do you think you could make her cum before you do?
