She moans deeply as you lean her in and give her a nice hearty kiss, filling her drow mouth with your tongue, while groping her small and tight butt. All of which makes her moan back into your mouth and grind her butt all the harder into your crotch, being a very lewd slave and how kind and dominating her master is being to her! Wiggling some more and moving a little, and moving from sitting on your lap to straddling it, wrapping her legs around your waist and the chair to better provide humping of your crotch as you kiss her deeply.
