She's 'convinced' to do what she's told.

Dee is very nervous.
Christine is very excited.

"Are you sorry?"
"Yes, I'm sor-RY," Dee says, surprised when her nipples are pulled on.

"Are you?"
"I am! I am! Yes, really."
"Will you do anything to prove it," Christine asks.
Dee pauses.
Christine pulls.

"Yes, I will-LL do anything."
"That's what I want to hear. I want a good show from you."
'Did she mean 'showing' or was she...'
"If you ignore me, I get handsy. Understood."
"Yes, Mistress," Dee says, quickly.

Christine looks down towards the hidden camera.
She meant to say 'good show' after all.

"You don't like your nipples played with, do you?"
"No, Mistress."
"I do though, don't I?"
"Yes, Mistress."
"Then pleasure them with your tongue."

She frees her tits from the lingerie top and presents one breast to be sucked on.
Dee does not disappoint.

"As good as always," Christine says, "Keep it up and you'll be free in no time."
'I booked this room for at least an hour though, so....maybe not.'
