Late twenties, submissive/Dom switch (about 70/30), single, white, slim, sissy willing.
i have been in contact with a Dom who has no interest in a single male submissive, but would Dominate to own myself and any interested female submissive.
As i know him, he is an experienced Dom, 20+ years. He is assertive, hard, completely respectful of limits, intolerable to any behavior that is not respectfully submissive. I've known more than a couple Dom/me in my D/s life and he is one of the better ones. 
If you are interested in a submissive couple relationship message me. As i understand it, attention will be focused on the fem sub and not so much on me. I have included a pic of his cock, which he appropriately named the file.
