His older sister, Brenda Walker

Brian approached Brenda.

"Bark like a dog" he said.

"Worf, worf"

Brian was still suspicious that it was a prank.

"Take off your clothes"

Brenda stripped naked. Brian still wasn't fully convinced.

"Walk outside"

Completely naked, Brenda stepped out onto the front porch. Okay, this power was real.

"Piss" he told her.

Brenda suddenly found herself peeing against her will.

"Beg me to punish you" Brian said.

"Oh, my Master! I am just a naughty girl! Oh please, punish me, Master!"

"Alright, slap your own red until its red"

Brenda slapped herself on the ass.

SLAP!

"Ouch!'

SLAP!

Brenda found herself slapping her bare buttcheeks.

SLAP!

Seeing that his sister's ass was red, Brian commanded her to walk naked round the neighbour for thirty minutes.
