Special Edition: Permission to Masturbate

My fantasy: to get permission from Wife to masturbate, with conditions...

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!

Wearing only white briefs and socks, I approached Wife, who was seating in the living room.
"May I masturbate?"
"Under my rules, yes."
Which meant, to start with, she watches.
I lowered my briefs, and sat down, and began looking at porn videos on my phone...and I began stroking my penis, slowly, then harder and faster...
and as I felt myself at the Point of No Return, I let go of it, putting my hands at my sides, and watched as my penis twitched and spewed cum on my belly.
"Lick it up," she said.
I dipped my index finger in my cum, and put it in my mouth, and continued, til it was only kinda damp, then I cleaned up the residue with tissue.
"Okay," she said, "Now get up and get on the bench."
I got on the bench and 

After fifty hard smacks, she said, "Get into the corner there."

"Now, stand there and think about what might have happened had you NOT asked permission first.  I'll let you know when you can come out."

I closed my eyes and 

Poof!
I was home again.
