As the third finger slid aside the other two, joining them in the hot stocking of Lisle kitty's suckling bottom, Gerlinde felt triumphant.<br/><br/>She was doing it:  She was teaching again; transforming.  There had been moments of bitter doubt - moments of indigestible fear of what was to come - even moments of rage.  Throughout, there had been a transcendent and unharnessed intensity.  But time and again, Gerlinde had steered the strange dynamic between Lisle kitty and she back to that of unconditional subject and Mistress.<br/><br/>'Mistress' - the old name for an instructor.  Gerlinde felt in full fettle in that role.  She sailed her stare around the green trembles in Lisle kitty's eyes, soaking in their yielding and caught in their currents.  She savored the silent acceptance and the flushing arousal she was inspiring.  She enjoyed the lips too taken by wonder and thrill to close; enjoyed the clamp of the pussy quaking around her penis.  And above all, she relished the carnal component of this 'education' - the classic 'Socratic - the slide of her fingers in a hole that should open only one way, but has been taught to be invaded, deep and grateful.<br/><br/>Gerlinde felt shiny and gold-strong again.  Her invincible peace had a polish of pride to it.  Even the fears to come - Lisle puss', her own fears of the Kommandant, the dread and yawning unknown - seemed not too vast to be overcome by that spreading serenity.<br/><br/>Spreading, Gerlinde thought as she watched three fingers - over an inch's width of flesh - gore smoothly in and out of Lisle kitty's anus.  Yes.<br/><br/>She could spread anything enough: That scarlet, suckling hole; those wide and learning eyes; the fatness of Lisle kitty's clitoris - all proved this so.  And her new idea would keep Lisle kitty secure.<br/><br/>Gerlinde purred to feel the hardness of the world, the stiff order of it, relent under her smooth touch and melt for more.<br/><br/>"And soon," Gerlinde said to Lisle kitty's beacon bright eyes, seemingly appropos of nothing but shoving the wide lance of her penis deep.  "You will be wide enough to take me inside.<br/><br/>"Feel?"  Gerlinde churned the spade of her three fingers in the yielding space.  She skimmed the ivory press of her belly over the crushed spike of Lisle kitty's clitoris.  Her penis drilled, Gerlinde's hips dancing wide and slow, scooping the clinging interior of Lisle kitty in patient choreography with her fingers.  "Feel how much you've stretched?<br/><br/>"And how good it feels?"
