Try and plead with the highwayman

"Please," you begin talking to the tabaxi. "I have no money on me. I just barely escaped the razing of my village by orcs. I'm just trying to get someplace safe. There is no point in killing me now."

The tabaxi looks at you with cold feline eyes. "Your life then," he replies. He steps forward and grabs you by the arm. You yelp and tremble as he brings the knife closer to your throat. You shut your eyes, waiting for the inevitable. You feel the cold metal of his knife touch your neck.

However, the knife does not end your life. Instead, you hear the tabaxi sniffing the air around you. You slowly open your eyes to see him pulling the knife away and instead bring his face closer, taking carefully sniffs at you. You can see his eyebrow rise in curiosity. He notices the knife on your belt and quickly discards it into the nearby grass. He returns to taking deep whiffs of your body. He travels down your breasts, then your belly, all while holding a strong grip on you. He finally buries his nose into your crotch and takes a deep smell.

You gasp and blush in surprise. "What... what are you doing?"

The tabaxi thief looks up at you with a wicked smirk. "I can smell it," he says as he stands back up and brings himself closer to you. "You are in heat."

"What are you talking about," you say as you try and struggle free. The beast man keeps a strong grip on you, making you unable to tear away.

"Your body is ready to be mated. It burns for a male's seed," he says as he continues to take sniffs, intoxicated by whatever it is that he's smelling. You suddenly realize what he means. Your body is at its most fertile part of the month. "I always thought human females were filthy, but never have I sensed such a scent from one before. Perhaps I shall try it this one time," the tabaxi says as he presses your body to his.

He's slightly taller then you, and you can feel something rubbing against your belly from the highwayman's crotch. Your eyes widen when you sense what his intentions are. "I wonder if a human woman can bear my child." His grin widens at the thought. "If you have no gold, then your body will do fine in repayment. Now, go lean against that tree, present yourself to me if you value your life," he commands you. His grip loosens as you are let go. He stands there waiting for you to submit to him.

You are no longer restrained. You could try and make a dash for it, but the beast man would have no trouble catching you. You notice the spear at your feet. You could dive for it and make a stand, but you're not sure how skilled the tabaxi is. Lastly, you can simply pay this creature with your body and have your life spared.
