"She wants me to put on a good show, but how do I do that?" you wonder. You know where you hid the camera that will be my eyes and ears.
"I'll have to make sure she can see well."
You quickly run through the rules for tonight in your head. There shouldn't be anything too difficult. Mark hasn't arrived yet, but you want to keep me happy.
You decide to perch on the bed facing the camera and masturbate, knowing I'll be doing the same thing on the other end of the connection.
You make sure your legs are spread wide apart so I have a good view. Then your fingers begin the familiar dance around your clit, while your other hand goes for your nipple.
"Maybe I should get a little fancy for the camera. She'd like that."
You slowly insert one finger, then two inside yourself. You continue to roll and pinch your nipple as you fuck yourself with your fingers. Luckily the house is empty, because your moaning makes it very obvious what is going on in your room.
You hear the door. Mark is home.
I see you leave the room and I hear muffled voices as you fill Mark in.
"You better not be telling him about the camera until after you're done," I think to myself, watching the video feed. But I'm not worried. You are such a dutiful sub, and I know I made the rules clear to you.
When you come back in the room, I hear you say the words I asked for: "I want you to use me, Mark."
"What do you mean use you? How?"
"I don't want you to think about my pleasure at all tonight. I am your fuck toy to do with as you like."
"Seriously?" Mark grins.
"Absolutely."
"Hmm... If I could do anything to you, what would I do?"
His eyes feast on your naked body for a few seconds while he makes up his mind. They travel across your awesome breasts, down to your delicious cunt, then he turns you around and stares at the delectable booty.
"Alright, beautiful. On the bed, face down, ass up."
You obey without question. Your glistening cunt is evident even to me on the video.
