'Master is pleased' (You wish she was an anal virgin).

"Master wishes he was first to fuck your ass, but is happy that Fucktoy is offering it to him." You start licking her ass, moving inwards to her anus. You press your tongue deep into her, glad you no longer have to hide your rimming fetish.

Karen jerks her ass, rocking and clenching it, trying to fuck and grip your tongue. "I'll be a good little ass-slut and let Master have his way with it. Master's cock is really thick and it's been a while since Fucktoy's done anal. She wanted to train her ass before offering it to Master as a surprise." You withdraw your tongue and kiss her hole, delirious with joy that you get to openly make out with her ass.
