"Yes, Mistress, I understand."
In truth, I didn't really understand. I didn't understand how it was I'd gotten myself into this position, but every time She spoke, I listened and did precisely what I was told.
"That's a good slut," She said into the phone, and then it went dead.
I sighed. Not even a "goodbye." As I drove home from work, I realized that I was completely at Her mercy, and would do anything She asked - or told - me to do. There was nothing I could refuse Her. I was, as she put it, Her slut - to be used in any way She saw fit. Tonight would be no exception. She had just informed me that I was to head home directly from work, go up to the bedroom, and put on the things she laid out for me. I'd found the "Adventure Night" love coupon this morning, tucked discreetly into my briefcase. Adventure nights always promised something fun and different, and I grew excited at the prospect of whatever she'd lined up for me tonight.
The last one was what had me calling my beloved wife "Mistress." The end of that adventure had me signing a contract that, if I could do it for a month, she would make sure that every adventure from here on out would be well worth it. So I agreed. That was the thing about Adventure Night - whoever left the card for the other one was assured total compliance. It was a trust game, really. I trusted her not to push it too far, and she trusted the same. That month from the last one ran out tomorrow, and now Mistress Ali was about to make good on her last bit of this adventure. In the last month, she'd tied me up, dressed me up, blindfolded me, forced me to suck her large dildos, and generally had her way with me, including even forcing a butt-plug up my virgin ass. I'd spent more time being hard in the last month than I could recall. I had no idea what I was in for tonight, but my cock was practically bursting from my pants as I walked into the house and ran up the steps to the bedroom.
There, on the bed, I found the outfit - if it could be called that - along with a letter.
"My sweet slut - tonight, you are Mine. You will shower and shave - and I do mean shave EVERYTHING - I want my slut smooth all over. Then, you will dress in your proper attire for the evening. Do not touch MY cock, except in the cleaning and shaving, and to dress yourself. You will greet me as I come in the door on your hands and knees. Tonight will be one you will remember for a long time, I assure you." Mistress Ali
I looked at the outfit and my cock stirred in my pants once more. There was a pair of lacy black thong panties, stockings, and a barely there French maid's uniform that would hide nothing, I was sure. A pair of black heels completed the outfit. She was right - I was pretty sure I would remember this night for a very long time indeed. I went into the bath and proceeded to shave my body and wash up, and then set about getting dressed. Rolling up the stockings, I loved how they caressed my now hairless legs, stretching over and smoothing out my masculine legs, making them look feminine even to me. The panties were next, and my cock was instantly hard in the skimpy lace. I put on the uniform last, followed by the shoes, and stood, looking in the mirror. I gasped at what I saw. I was completely lost in my reflection when my phone rang. I picked it up.
"Yes, Mistress Ali?"
"Are you dressed yet, slut?"
"Yes, Mistress."
"Good. Send me a picture of you. Then, I want you to get the butt-plug from your nightstand and insert it. Be a good slut and have it done in five minutes."
"Yes, Mistress."
The phone went dead again, and I hurriedly complied, snapping a picture of myself in the mirror and sending it to her, and then inserting the big plug into my ass. It hurt, and I had to rush it, but I managed to get it inside in 4 minutes, and sent her a message indicating so.
"Good slut. I will be home in 20 minutes."
I eagerly went to the door to await my Mistress and waited, on hands and knees, just in case she was early. I only had to wait about 5 minutes when I heard the key in the door. I turned to greet Her, and was surprised to be looking dead into the face of my sister-in-law, Heather.
My face must have turned several shades of red instantly, as Heather first just gaped, and then burst out laughing, but she did not shut the door.
She put out a hand to stop me from closing the door. "No you don't. I want to enjoy this for a little while."
I'd never really gotten along with Heather. While she was a nice enough person, and I was never outright mean to her or anything for my wife's sake, there was just something that never really worked between us. Maybe it was that I took her sister away from the family - I don't know, but we'd never really seen eye to eye, and now that she'd caught me in this situation, I suspected it was only going to get worse. I was right.
I heard the car pull into the driveway and knew that my Mistress was about to come in and see the whole situation. Me, with a plug up my ass, the panties straining to hold it and me in, the maid's uniform, the whole thing, and my wife and Mistress about to enter the room. And I knew what I had to do. I went back to my hands and knees, awaiting my Mistress. Upon her appearance at the door, I greeted her, saying, "Good evening, Mistress Ali."
She looked around, saw her sister still laughing in the corner of the foyer, and then looked at me.
"Well, I'm surprised, my slut. I didn't think you had it in you to remember your place."
"Thank You, Mistress," was all I said, bowing my head.
She reached out a hand and patted me on the head. "Good slut. I shall reward you, assuming you continue to please me...and my sister."
My look of panic must have been clear to her, because she laughed long and loudly while she shut the front door.
"Yes, my slut. Heather here told me several months ago how she wanted to try fucking a man's ass. This last month, you've been coming to this point all along, and here you are, wearing panties and a servant's uniform, a butt-plug stuck up your ass, all ready to service the two of us tonight."
I looked over at Heather, only to see her expression had changed from laughing to lusting. "Does he really have a plug up his ass?" she asked.
"Turn around, slut, and show Mistress Heather your ass."
Mortified, I did as my Mistress commanded, pulling aside the panties to show Mistress Heather. I felt a hand slap my ass - hard - and I let out a little yelp of surprise.
