She begged him not to, but as he predicted, he was before long able to make her cum that way. And before long, she came to view the one full stroke as an orgasmic treat. To get really fucked until she screamed and came constantly, she would agree shamelessly to anything. And the last shameless thing she had agreed to, she was now in the process of doing.
For the last several weeks, while he had used her ass regularly, he had not given her more than the tip in her pussy. He had suggested that since her ass was so well trained, perhaps that was all she needed except for the tip, but that he did still love fucking a wet pussy. He asked if she would like her slavish need shown off to a third person and she had surprised herself by saying she would. She had agreed it should be a woman. She had agreed that she wanted to be exposed for the submissive she was, ass fucked and tip trained in front of another woman. And she agreed that she would help prepare this woman's pussy so he could fuck it in front of her since she deserved only the tip. Why she agreed to this outrageous demand? He had agreed to give her a real fucking on that day when she did agree. He had described in detail how that it would be in front of another woman, her jealousy, her arousal, her submission, her humiliation. And yet she agreed because her body betrayed her. Talking to her with the tip of his cock in her, his voice and hands enveloping her- it wasn't fair. She yielded, ashamed at her desperate need to say "yes" to him
So now, here she was, laptop in front of her, and he was making her write the ad to find the woman to witness her further drift into deeper submission. He was dictating, so to speak, and had told her that with each completed section of the ad, he would give her a deep stroke and she could cum hard. And when she submitted the ad she would get properly and deeply fucked.
He dictated the title. "Please help, my Master needs a pussy to fuck, I'm only allowed the tip of his cock." She typed it, he slammed in hard. She screamed and she came. When she regained control, she hit the "tab" key and prepared for his next words.
