Terror filled the girl's eyes.  The nub had extended a full inch from its former hiding place, seeming to grow with every frantic heartbeat.  At the question, those green orbs lifted from the display at her groin and met the ice blue of the doctor's gaze.<br/><br/><em>What is the correct answer?</em>she wondered, appalled at what was happening to her, but not wanting to lose her ability to speak.  The tapping caused her to arch again, straining at the leather bands.  The feeling was intense - far more intense than any self-stimulation that she had ever engaged in.  She felt herself spread wide before drawing the rubber egg between softly pulsing walls.<br/><br/>"I - I - t-too much!  Oh god - I - I can't -"  She was writhing now, flushed and even perspiring despite the chill.  Her changing flesh was hypersensitive to the point where pleasure became pain.  She bucked in the restraints, but the flooding testosterone kept her from feeling any satiation.  Her eyes glistened as she tried to focus on the musky-smelling finger approaching her face.
