Girlie is a pathetic submissive who desperately wants Mistress Rosa to use her mouth as a fuckhole. She hasn't earned such a reward yet, but she has earned a finger fucking. Mistress sticks her fingers deep down her throat, causing her to gag and spit-- which Girlie just loves. So Mistress plays with her spit a little, using it to lube up her hand for more finger fucking and a few well deserved slaps.
