#144 Naked, prone on bed, hands restrained in front of me and severely whipped with a birch.

My fantasy: to receive a birching that leaves long lasting marks on my bottom and thighs.

POOF!
In a cloud of smoke, a Genie appears in front of me, and intones,
"I am the Genie of Fantasy.  I can not make you rich or famous, but I CAN put you into any fantasy world you wish.  You can stay in the fantasy world as long as you want... you can say the words, "Teenie Genie, take me home" or if you fall asleep, you'll return to this real world, and only one minute in real time will have passed."
I eagerly tell him what I want.
POOF!

In Will's bedroom:
He says, "You ready for this?"
"Yes."
"Strip."
I do. He puts cuffs on my wrists, tells me to lay prone on the bed. 
I do. He attaches the cuffs to ropes at the head of the bed.
He picks up a birch and begins:

More lashes than I could count.
I was crying in agony.
He stopped, and said, "Let's take a break."

I closed my eyes, and 

Poof!
I was home.
