I walked back into the living room with two espressos. Tatiana was sitting opposite our visitor; her legs pressed together demurely, her hands clasped in her lap and her head slightly bowed. I placed the coffees on the low table at the side of the leather armchair.
'Thank you.'
Our visitor picked up her coffee in a leather-gloved hand and sipped it. I sat down in another armchair.
'This is your woman?'
I nodded. Tatiana blushed and looked down, smoothing her dress down nervously. Our visitor smiled. Her gaze was intent.
'You have both discussed this?'
'Yes'. Tatiana nodded.
'You have a safe word?' She looked to me.
'Yellow for slow, Red for stop.'
Turning to Tatiana, 'This is correct?'
She nodded
'You are willing to submit?' This was directed at Tatiana. She nodded again, and swallowing hard, she struggled to reply.
'We must choose a name for you.'
She stood, and walked to the bookcase, the heels of her boots clicking on the wooden floor. Picking a book, she flicked through the pages.
'Maria. That will make a good slave name for you.'
She put the book back slowly and deliberately. She turned to face Maria.
'Stand, Maria, step forward from the chair so that I may see you.'
Maria stood, hesitantly stepping forward. In stockinged feet, she was much shorter than our guest. She held her hands together at her waist. Our guest circled her slowly, lifting her long blond hair and stroking the side of her neck. Maria shivered. She traced the curve of Maria's back through the fabric of her dress.
'Strip.'
The word was whispered, but cut the silence like a knife. Though I was shocked, I felt my arousal growing to see my wife commanded by another woman. Maria looked at me, her eyes pleading.
'Do as she says, my dear. You will not be harmed. When you are addressed as Maria, obedience must be instant.'
Maria swallowed, and reached behind her back for the zip. Fumbling slightly, she pulled it down and shrugged the dress from her shoulders. It fell, pooling around her stockinged feet. Except for her black hold-up stockings, she was naked.
'Step out of your dress and kneel before me'
Maria obeyed, putting her arms over her breasts and her pussy.
'Head to the floor. Kiss my boots.'
'But...'
'Silence, slut. You will learn to speak only when asked. Kiss my boots. Now!'
Her tone had hardly risen from a whisper. 'That is better, my little one, slowly and more lovingly.'
Maria continued to kiss her boots. My erection was now straining at my trousers. The contrast of Maria's pale skin with her black stockings, her naked softness with our guest's leather boots was the most erotic sight I had ever seen.
'You may stop now. Kneel up, hands behind your back.'
Maria complied. She was flushed, breathing heavily, but her head was lowered. Her breasts were beautiful, round and firm, with erect nipples.
Our guest circled Maria twice more and returned to her chair.
'Maria, you are clearly a natural submissive. I will ask you some questions, and you must answer truthfully. When you answer, you will address me as Mistress. Do you understand?'
'Yes, Mistress.' she murmured.
