This guy had info that mistress Natasha wanted. But he had refused to give it to her even when she promised to pay for it. He could sense she was desperate and he wanted to make her even more desperate. But he did not realize that the same desperation would make her force him to do what she wanted. And so the mistress choked the guy and got the information for free.
Mistress Natasha had grown tired of the childish way her boyfriend acted and she felt that it was time he changed and became a responsible person. So she forced him to lick them after she choked him with her strong arms. He regretted what he had done and he knew she was not to be messed with. That is how he came to change and do the right things always.
Mistress Natasha did not want to waste her time on this loser. He had messed with her and he had angered her. So she punished him by choking him using her sweaty armpits. The mistress had a great time choking him and he cried in the process. However, mistress Natasha was not moved by any of his cries and pleas and she continued to humiliate as well as to dominate him.
Mistress Natasha was not ok with how her slave behaved badly in front of her. He was behaving like a toddler and she did not like it. She had admonished him but he did not seem to change and she had to change tact. She did so using her sweaty armpits. She choked him with her sweaty armpits and to cut a long story short, the slave never messed up again.
