Spank her

"Get on the bed.", you tell her, "on your stomach." She obeys without a word, turns around and starts climbing on the bed. "Hey!", you yell at her, "I didn't hear you say 'yes, master'!" She briefly looks back and mockingly says it. You just stand there, fuming. Play-fuming, that is. You're not really mad at her, of course. "That was pretty disrespectful for a girl in your position. Looks like you need some extra punishment."

You push her down on the bed and untie the apron. You run your hand softly along her curves and cup her ass and give a little squeeze. Then, smack! "Oh!" she blurts out. Again, smack! Again, "Oh!". "You like that, you little whore? You like when I punish you?" Smack. "Oh, yes master! Please do it again master!" Smack. "Oh!" Smack. Smack. Smack.

After a good few minutes of spanking her ass, both her cheeks are slightly red; you were actually pretty gentle with her. You're thinking about what to do next. Maybe eat her out? Fun, but she would enjoy it too much. Turn her over and fuck her face? Tempting but you don't want to overdo it with her mouth, you'd like a real, full blowjob later maybe. That leaves sticking it in her and fucking her prone like that, which is always a favorite, or....ass? Do you dare try the ass? Hmm, better not risk it you think. That settles it then, going in...and *Beep* *Beep* *Beep*

"Master? Your cupcakes are done. Shall I get them for you?"
