Emma leaned in, over me, unsmiling, collecting her thoughts:
"I met Helmut at the staff's Christmas party at his father's firm. You know, the Master Builder. I had worked there for the past two years as the firm's sole office staff. Helmut, a Diplom Engineer, worked for a large international construction company and was only home for a brief holiday.
"When I managed to get and keep his attention, what attracted me most was not that he was undeniably a desirable prospect. He was an attractive, well-groomed man, single he told me, and an affluent professional and heir to a, I well knew, prosperous business.
"But what swept me away was Helmut's domineering maleness, his being sure from the moment I attracted his attention that I was his for the taking.
"I was then neither a virgin nor -- sexually -- a shrinking violet. But when he took me, before the party had even finished, up to his room, undressed me without asking, and then, with no foreplay fucked me, I turned into a submissive, blubbering, gushing mess. I was his. Just as I watched your sister Kate becoming his years later."
A protesting sound from me stopped Emma in her tracks. She grinned:
"Surprised? Well, more about Kate and us later. Here I am just mentioning in passing what effect Helmut had on both of us. Men like him turn most if not all women on... and into submissive sluts.
"My special dresses Helmut and I found at a little boutique fashion shop in Alexandria. It specialised not in one-of-couture but in modernised versions of traditional oriental dresses that local seamstresses made to order.
"What attracted my attention was a slim, tube-like caftan on display. Traditional in cut, it covered the body from neck to ankles. However, unlike the traditional ones in heavy-weave, plain cotton, this caftan was crafted in a feather-light, possibly body-hugging, I thought, cloth.
"The shopkeeper, a beautiful Egyptian woman, had noticed my interest.
"She smiled at Helmut conspiratorially and asked him to allow me to try one on. Helmut allowed it, and she took me to the back.
"When I had stripped to my underwear, her mouth clicked approval. But then, shaking her head, she undid my bra. And when she stroked the caftan's supple material down my body, she looked disapprovingly at my panties. I thought she disliked their sheerness.
"Then she led me out the door to show me to Helmut. He sat in a chair. I turned, stretching out my tits and ass, hoping the cloth would cling.
"The woman just smiled. She took my arm and led me to the shop's large window to look out like a display figure. Then she slowly turned my back to the window, and I faced Helmut.
"He had tensed in his chair and stared at me in obvious surprise.
"Suddenly he grinned and said he liked me in this dress; he would buy it for me.
"When I had changed back into my clothing and joined Helmut in the shop, the woman wrapped up my dress. Handing it to Helmut she said that the other three he ordered would be delivered in five days.
"Back in our apartment, Helmut asked me to put on my new dress and be naked underneath. I happily complied, glad that he found my dress as sexy as it felt on my skin.
"For the next hours, his eyes followed me as I moved through the rooms doing my everyday things. I loved it and tried to pose sexily. I was slightly disappointed that my dress, I thought, showed no more than the occasional bulge of a nipple.
"At nightfall, Helmut could wait no longer.
"By escaping his grasp and pulling it quickly over my head, I just saved my dress from having it torn off my body. Then he fucked me -- on the floor, on and across the sofa, and, finally, against the windowsill. Ours was a third-floor apartment and my tits were squashed against the glass. He possessed me, driving me from climax to climax in a blind horny rage as he had never done before."
Emma, as she talked, had sunk back on a large cushion. Inadvertently, perhaps, her gown had split open. I could see her hand cupping her pussy and her bent, diving-in fingers. When she saw that I saw, Emma smiled.
She licked her lips with a sigh and continued:
"So, you see, Tom, this favourite dress of mine has been, from day one, associated with mind-blowing sex. But I had put it on without knowing what the Egyptian woman in the shop had shown Helmut.
"Helmut, however, did not want to leave me unknowing.
"The next afternoon, with the sun streaming in through the living room's window, he asked me to strip and put on my dress. Flattered, I thought he wanted to photograph me, and I happily obeyed.
"While I stripped naked and slipped into the caftan as ordered, Helmut shifted our large dressing mirror against the wall opposite the open window. But there was no camera in sight.
"Taking my hand, he led me to the window. For a moment I thought he would fuck me again, this time leaning out. But he only asked me to look back at the mirror; over my shoulder, without turning.
"I did and gasped in shocked surprise at seeing my naked backside, cast in a yellow glow in the mirror. It hit me immediately. This suddenly see-through dress rendered me, my silhouette and the voluptuousness of my ass with its dark cleft merging into the swell of the thighs, disturbingly sexy.
"When Helmut turned me to face this so different myself in the mirror, I suddenly knew what had driven him the previous night. The darkness of my prominent nipples and the triangle of my bush on my sinuously aglow body made me sinfully alluring.
"And as I started to move, sensuously twisting my body, my dirty mind suddenly knew that in this oriental dress, I was an irresistibly tempting, fuckable slut!"
Emma paused, looked for my reaction, and continued:
"The how fuckable I was, I quickly learned. For, as I got more and more turned on from my posing and twisting in front of the mirror, it ended again with us rolling on the floor and Helmut fucking me into quivering submission.
