The thought of having an entire new uniform made just for this purpose sends a thrill down Lucifer's spine. He growls low in his throat, the sound vibrating against your back as he roughly pushes you onto your knees. "Very well," he says, reaching out to cup your chin and force your gaze up to meet his. "But first, I think it's time we discuss some rules."

His thumb traces circles around the dip in your chin as he speaks, his voice deep and commanding. "Whenever I'm with you like this, you will address me as 'Master'. Is that understood?" He pauses, waiting for your response. His other hand slides down to cup your ass cheek, squeezing firmly.

"Good girl," he murmurs, pleased when you nod in agreement. "Now, about this uniform..."

"From now on," he says, his voice smooth like velvet despite the harsh commands it holds, "you'll wear a new uniform made of nothing but black leather. It will cover your most private parts and leave your ass and thighs bare for my enjoyment." He slides his hand between your legs, fingers seeking out your entrance as he continues to speak. "And when I want you to serve me in this way, you'll make sure that you're always clean and ready for me."

His other hand grips the back of your head, forcing you down onto his cock with a groan. His fingers curl into your hair as he thrusts roughly inside you, taking what is his with such possessive fury that it leaves no doubt in either of your minds who truly controls this situation.
