I love getting a teaser before that first date.
Your wife embraced her freedom you wanted and craved for her to have. You may be away for business, but she will take advantage and accept a dinner date with a man and show you what she wears for him. That excites you and she encourages you to rub one out if you like. If it helps, she says he won't have to masturbate. She's going to rock this guy's world. That helps.
She's not angry, she'll just have to get used to you as her cuck. Now that she is freely enjoying other men you are more attached to her than ever. Her body gives you rock hard boners. And seeing you wank to her body when she is dressing for another man is one thing. Seeing you cum so quick and easily and have cum dripping from your fingers as a result is another.
