xxx184 DD kneeling for a short strap

My fantasy: strapped while standing  then kneeling

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!

"This time," Jill said, "I'm gonna try to give you a REALLY rump."
"Oh boy," I said, without much enthusiasm.
"O come on,' she said, grinning. "You know you like it."
"I also like sitting, which is difficult to do when you're done with me."
"Oh, sitting is over rated. We have company coming, so we have to make this kind of quick. Just take your pants and briefs down, and stand against the wall, hands on the wall.
I did and 

"That's a good start," she said, "Now kneel, with your torso over that chair."
I knelt and she began a hard fast application of her short strap.

She stopped and said, "Now that's the look I was going for. Hang on, gotta take a picture of that.  Okay, get up and get your pants up."
Groaning, I very gently did so.
and I closed my eyes and 
Poof!  I was home.
