She's pleased...and punished.

Dee knows how to please her girlfriend.
She knows how important that is right now.
She needs to make her happy.

Christine controls her reactions, but has a small orgasm eventually from just the right amount of sucking on the right spot.

'Still rolling? Wonderful!'

She tells her submissive girlfriend that she did a good job.
She likes to hear that.

"Give me a kiss."

She leans in and kisses Dee, who leans forward to reach her.
Their tongues dance.

As the kiss ends, she catches her girl's tongue with her teeth, holding it for a moment to remind her who's boss.

"Now I'll show you what else I can do with my tongue," Christine says.
"Will you untie me first?"
She gets a 'really?!?' look from her bossy girlfriend.

She lays down on the ground in front of her frog-tied girl and starts to lick her pussy.

If Dee wasn't too distracted, she might wonder why the woman was turning to her side while she licked her.
The idea is to not block the camera, of course.

She knows how to please her girlfriend.
She knows how important it is right now.
She needs to get her close to the edge for what she has planned next.

She hits just the right spots and the tied blonde is about to orgasm after only a few minutes.

Right before, she stops and sits up.

"Is this my pussy?"
"Yes! It's yours. Please let me cum."
"I think you need a reminder," Christine says, grabbing both lips and pulling them apart.

"You'll cum when I want you to.
You'll cum when you've earned it."
