Nikki held up her hand, motioning for you to stop, as she molested you with her eyes. After making a big show of looking you up and down, she held up a pair of handcuffs, dangling off her finger. "Are you ready to stop talking and start playing?" It wouldn't have mattered if you said no, she easily noticed your cock throb in response. But you didn't say no, you said yes. Nikki slipped the handcuffs onto your wrists, behind your back of course, and gently traced a fingernail across your chest. It was so erotic! The powerlessness from the handcuffs, and from being so exposed in front of her when she was so not-exposed, combined with the arousal from her touch, from her expression, hell just from HER! It all made the situation hugely arousing. And with your hands behind your back, it left you no way to conceal that growing arousal, which made you feel even more powerless and exposed, which made you even more aroused. The vicious circle was maddening!
