Not just yet

Sarah had finally managed to undo both the top button and zipper of my pants and was sliding her hand inside my boxers. Unhindered by similar considerations, I was already stroking between her legs, sliding fingers past her engorged labia, ready to taunt her and the intern before we really got down to business. The doctor's stance widened slightly as she tried to give me better access and slightly pushed her pelvis into my hand, trying to get me to enter her moist pussy.

Lakshmi had switched from biting her pencil to her thumb, with the now neglected pad resting on her chest. Watching for a moment, I could see that she was running the spiral binding across the engorged nipple obviously poking out from her shirt. But she otherwise obeyed the doctor's orders and remained standing where she had been.

Sarah's hand had reached my crotch, running her fingers through my pubic hair to grasp the base of my penis. Her other hand was trying to slide my pants and boxers over my hips, so I used my free hand to help her. With access no longer a problem, she began to slowly pump my cock with a firm grip, while she gently raked the nails of her other hand from my thigh up to my chest, eliciting a shiver. As she pressed herself more firmly into my back, I could feel the heat of her body against mine and the extra weight of her breasts.

No longer satisfied with my teasing, she reached from behind between her legs to spread her lips; a few drops of moisture fell on my fingers.

Craning my neck back to whisper in her ear, "Tell me what you want."
