The blonde college student moaned, clutching the bedcovers in her hands as the high-powered vibrator stimulated her as she had never been before. She couldn't believe how close she was to climaxing, but couldn't go over the edge. Kristina had no idea that Derek's command not to cum had blocked her ability to. Yes, she was obeying his command which was weird to say the least, but she didn't suspect that she had been hypnotically conditioned to do as he commanded.<br/><br/>Everything Derek did seem to make Kristina melt into her pleasure and need to cum. The vibrator was doing a lot of the work, but Derek was the one wielding it, and the hand at her sensitive breast was almost as effective at pushing her boundaries. But, still, she couldn't fall over the edge into ecstasy.<br/><br/>"Please....please.... tell me I can cummmmm..." Kristina moaned hoping that permission would let her achieve the climax that she was craving. Permission didn't come, but rather a command. Almost as soon as it was comprehended, Kristina rolled to her side then over to her back. Even as her thighs parted, her hand moved to her knees to pull her legs open displaying herself to Derek. Kristina would never do this, not even in the dark, but here she was obediently spreading like some porn starlet! Her mind made some rationale that it was because she wanted to cum, and that she wanted to please her lover, but the fact was that she had done it simply because Derek had told her to.<br/><br/>"Mmmm please Dee. Let's cum together... I need you so bad," Kristina found herself begging with no thought about the words. It was true. She did want him badly, but the last spark of free thought in her mind was trying to work out why that was so.
