That's not immediately clear

Smiling, he watches your crawling approach. Although he's smiling, there is a coldness in his eyes that makes you nervous, a flutter of anxiety joining the flutter of excitement in your belly. You crawl to his feet, then sit back on your haunches, staring at him, your panties dangling from your mouth, your eyes entreating him.

He doesn't respond except with the same cold smile, and you decide to take things further. Leaning forward, you put your hands on his knees and start to stroke your hands up his thighs. To your surprise he pushes his chair back a few inches, then puts his foot against your chest, stopping you. He looks at you silently, keeping a slight pressure on you with his foot. You hold his ankle, stroking it with your slender fingers, your eyes looking a question at him, your panties still dangling from your mouth.

He seems to be expecting something, but you're not sure what it is.
