“Good girl,” Vanessa praised, and then began to pull the line of packing tape. It gave a rich purr as it came free, and as it neared the end, she had to use both hands to free Keiko’s hair from the sticky bands. At last, the several feet of it were free, and she plucked the sopping panties from between her lips, discarding both them and the ball of used tape to the side.<br/><br/>“Now that Miss Watanabe has agreed to be a little more obedient, it’s time for a little role play,” she said to Michael and Keiko. Her hands returned to her student’s face, caressing at the lingering stickiness left from the tape. “Let’s pretend that Mr. Weston is the client who has agreed to purchase you, and he has had a<em>very</em>long day at work. After he comes home, he expects you to come straight to him and give him a nice relaxing blowjob to ease the stress away.”<br/><br/>She turned to Michael, draping on arm around his shoulder and leaned so close to him that a bare breast pressed against his arm. “It certainly looks like you had a stressful day, Mr. Weston. You look ready to burst.” Her other satin hand reached down and lightly circled around his bound, swollen girth, gently stroking it. Just as she had said, his tied balls looked like water balloons ready to pop, his entire shaft veined and throbbing. “However, the women who purchased you and David are more interested in how long you can last.”<br/><br/>Finally, she stood between the two, glancing at both of them with her hands on her hips. “So here is your exercise. You will each have ten minutes. Miss Watanabe, you will try and blow Mr. Weston to orgasm. Mr. Weston, you will try to not come during that time. Whichever one of you succeeds will be rewarded, and the other punished. Your time begins now.”
