Marie had made Julie cum within two minutes of starting to pleasure her, and I was still stuck there watching. I would have given anything for another chance right there and then, but I knew that was not going to happen.

Marie then moved towards a cupboard on the side wall and silently indicated to Julie to ask her permission to open it. The still moaning Julie allowed her pet to open the door, and from it Marie pulled a long purple dildo attached to a harness. She moved forward to show me the device that she was going to fuck me with. The harness looked like it had two small dildos attached to the inside, for Marie's ass and pussy, and the purple cock sticking out from it was longer and thicker than mine. I didn't know how she could possibly get that "THAT'S HUGE!!", without thinking about it. Julie immediately turned and smacked me across the face, hard enough to stun me, but not hard enough to really hurt. 

"QUIET!" 

Julie spoke again, taking control of the situation. "Marie, put on that harness carefully. Make sure you use lots of lube for that anal plug - it will hurt if you start moving around without enough lube. When you are all settled, please show Dave here how he can use his mouth in a more pleasing manner. 

Marie slowly slid the harness up and into place, moaning gently as the two plugs filled her holes, and once she was harnessed up, she moved in front of me. I close my eyes as she approached my mouth with the monstrous silicone cock, but I opened my mouth obediently and started to suck it as Marie fucked my face and worked the purple cock down my throat. 

Julie was the one to stop the action. She sent Marie behind me and the two of them moved back toward my ass.

I was waiting for a few minutes, and they stayed behind me, not touching or talking to me at all. Julie moved towards my head and grabbed the box from the counter. The box was the reason that I was here, and how I had got myself into this situation. The box was the think I needed to get to Gwyn at home. Now that I was reminded of the box, I was also reminded of Gwyn and the fact that I was cheating on her, with her friend and some unknown woman.

"Dave.", Julie said. "Before I give Marie permission to remove your plug and fuck you, and she is going to fuck you - hard - as hard as you can take it, and maybe a little more. I'm going to teach Marie how to fuck you because she needs to learn how to dominate a person like you, who is even more submissive than she is. Anyhow - Before I give her permission to take your anal cherry, I want to bring you back to our reality. Would you like to see what is in the box? Would you like to see what the solution to Gwyn's problem is? Or do you already know? You have my permission to answer."

I thought for a moment, as clearly as I could given everything around me. "I think that her problem is that I want her to be dominant like you, but she isn't cut out to be that way with me. She is naturally a little bit submissive sexually, but probably not as submissive as I am, so we are at odds. I think she knows what I want sexually, but doesn't know how to fulfill my needs, regardless of how much she might like. Is that close? But I still have no idea what is in the box."

"Very good Dave, I think you may have learned something today, and as a reward I think it's time for you to see what it was you were sent here to get." Julie took off the top of the box and set it down so I could see inside it. In the box were two things, a book and a piece of paper.

The book was called "The Art of Submission", and the piece of paper said 'You will both be submissive to Mistress Julie, either together or separately, whenever I call you or make demands of you.'

Julie stated "I'm not going to answer any questions right now. There will be lots of time for questions and conversation later." Julie reached around my head, drawing my face closer to her cleanly shaved pussy, and she put another gag in my mouth, this one forcing itself deeper into my mouth and throat. It was a smaller version of the dildo that Marie was preparing to fuck me with. The gag was held in place around my head, and it was sliding deep in my mouth and almost into my throat. I had to breath gently and intentionally to keep from gagging on it. "I want you to think about your answer to my question, and the contents of the box while Marie is fucking you"

"Marie - before you finish this part of your training, and Dave's training as well, remove your hood and come forward to thank me, and thank Dave for his gift to you. I think he might like to see your face before you fuck him."
