A domina to control and own you both

You cant take it anymore as your girlfriend only goes faster and faster, pushing you to the edge of orgasm, but not giving you any relief. So you admit the truth
"I want a domina to control both of us! I want us to submit to her together, for her to use one of us, or both of us at the same time!"
Out of surprise, Carrie completely stops jerking you off. You moan as you cum in a ruined orgasm. She quickly picks up the pace again but its too late, you dont get any pleasure out of your orgasm. Both of you watch your cum dribble down your dick, an impressive amount.
"Sorry", she whispers, and kisses you on the cheek.
"So..."you say, now a little embarassed of how straight forward you just were, "What do you think?"
To your relief, Carrie actually seems to like the idea. "I think that sounds romantic! Both of us submitting together, helpless, looking at each other knowing we can do nothing for the other but would do anything? Sounds great."

"The only issue is.." you say, while you look around for a towel or something to clean your cum off your stomach, "We need someone to...you know.."

Carrie, now somehow more straightforward then you, nods, "Someone to dominate us." Then she looks down at the small puddle of cum at your stomach. "Let me take care of you. Its my fault I ruined you anyway."
She slides down, and begins to lick your cum off your stomach area. She licks some of your semi-errect dick, witch twitches a bit under her tongue. She smiles.
"The reason I stopped so apprubtly was actually, that I think I know someone who would be perfect."
