Susan strolled out of the shower, her hair damp, wrapped in a fluffy purple towel I had picked out for her. "My, my, look what we have here," she said, as she walked towards where I was still tied spread-eagled in bed, my arms and legs bound to the posts with restraints, a tight gag placed on my mouth. "Who could have done this to my poor cucky?" She smiles as she reached out her hand, tracing circles on my skin. I almost gasped as she leaned over to kiss me, the scent of shampoo thick on the air.
"Is my cucky still upset that he didn't get to watch me shower?"
I nodded, as best I could with the gag.
"Well then you'll have to learn to address me properly won't you? I may be your girlfriend, but I am your physical and intellectual superior. I've told you that you may call me Mistress Susan, or Ma'am. Not Susan, and definitely not "honey". Do I make myself clear?"
I nodded again.
"Well I suppose you've learnt your lesson now," she said, undoing my restraints with deft hands and walking away towards the dresser.
My eyes lingered on Susan as I sat up and rubbed my wrists gingerly. In her late 20s, she was an absolute stunner, with her dark brown hair, startlingly green eyes, her perfect breasts and a sexy bubble butt that often drew the attention of men as we passed by. Any man she met wanted her, I could see it in some of their eyes. Lately it appeared almost everyone was getting their wish, except for me.
"Cucky", came Susan's voice from across the room, "have you picked my lingerie out for me yet?"
I hurried towards the closet, where I had kept the expensive bra and panty set I had bought for her that afternoon. The bra was a black, C-cup bra, accompanied by a set of boyshorts. I walked up to where my girlfriend was still applying her makeup at the dresser. She turned towards me, and held her hand out for the lingerie. "Kneel", she said, and I found myself complying immediately. Susan's voice had that effect.
I looked up at her, watching her study the underwear I had bought her, and I knew, immediately, that she wasn't happy.
"Do you remember me telling you, cucky, that I wanted my look today to be slutty?" she said, evenly, looking from me to the underwear.
"Yes, but..." I was at a loss. Certainly I'd known, but I thought the underwear would look great on her. Surely she wasn't...
"Do you know what slutty means?", she asked, a dangerous glint in her eyes. "Do you need me to define the word for you?"
"I do know what it means, Mistress Susan, I'm sorry-"
"Perhaps this qualifies as slutty for you, but tonight I'm going out with a real man. They have entirely different standards, and this falls way below the mark. How about this? While I'm away, you can spend some time writing an essay on the meaning of the word, its origins, and as a bonus, you can write a bit about exactly how your girlfriend should dress to appear slutty."
"Yes, Ma'am." There was no point arguing. Susan delighted in giving me punishments, and even more in punishing me for arguing with her. The last time this had happened, she had invited her best friend over, and forced to explain to her, in excruciating detail, our lifestyle and how she dominated me.
"Good," said Susan, "Throw this underwear in the trash. Fetch me the white push-up bra and the black ruffle booty shorts. And if this happens again, I promise you I'll invite Sheila over again. And this time, I'll let her do more than watch. Am I understood?"
