Deny it

She will be angry with you for snooping. You try to bluff through the moment

“No Mistress!”

Her grip on your balls tightens and you wince. That’s beginning to hurt.

“I’m disappointed. Honesty is very important.”

She knows! How does she know? Your bluff failed!”

“Mistress I’m sor..” you begin to blurt out but it turns into a scream as bright scarlet pain blossoms in your groin. A wave of agony washes over you and you collapse into a ball.

You gasp for air and slowly realise what just happened. Her surprise punch to your balls completely unmanned you for a few moments. By the time you sit up, cradling your aching scrotum you hear the front door closing. She’s gone.
