She barely holds out...and suffers more for it.

"Submit to me and you get to cum," Chantal says when she returns 10 minutes later.
"...no."
"It is pleasure OR pain. You'll have to be taught that lesson some more..."

Chantal begins to use a paddle on Jenni's poor, exposed feet.

After several minutes, Jenni is given a different sensation...

Chantal presses the vibrator against her sensitive pussy.
Not again...

"Remember that you can't cum without permission. Right, ****?"
"...yes."

After another minute, Jenni is at her limit.

"May I please cum?"
"No. Hold out."
"...please let me cum."
"No. Hold it in. You will be punished very badly if you don't!"

Jenni hold back her orgasm, but it is very hard.
It only gets harder as time goes on.

"Please let me cum!"
"Not until you say it."
"Say what?!?"
"You know what to say!"
"Please let me cum...Mistress."
"There we go. You may cum, ****!"

Jenni cries out as a larger than ever orgasm rips through her body! She strains against the ropes reflexively.

"There we go. Submitting to me wasn't so hard, now was it," Chantal asks sardonically."
"...no, Mistress."

"Now we can have some real fun before they send you away for the next bit of your transition. No SPOILERS though, dear."
