Kat grinned as she moved under her skirt and moved aside her panties giving her access to her wonderful folds. She knew the best way for her is to actually have a orgasm, she knew her mistress well. Smirking she moved under the desk just in case somebody walked in. Moving a finger inside her folds she then moved her mouth to lick the woman's clit. She learned a lot during her time as a patient to the point where she could pinpoint the exact Gspot of her mistress. Curving her fingers a bit she found her Gspot quickly and began to move her finger gently touching them and moving them apart from each other then back out. She kept doing the same thing to her as her mouth took care of her clit. After a good couple of seconds she pushed her tongue inside the womans pussy and began licking her folds and taking on all the juices. Her shaven pussy just below her nose she could smell the woman's scent wich she loved and could never had enough.
