With her tongue.

Emma dives in with her face. Giving a long kiss to her master's asshole. She needed to be tender and show her master love. Not that a neep could ever love a woman. No. Respect. Warship. She would show her master's ass reverence as it deserves.

"Greedy little... Are you looking at my pussy?" Martha asked. Emma shut her eyes tightly, locking out the image of her master's perfect pussy. This way she couldn't even tell how plump it was. She didn't know it was a thick sex organ, shaved and pink, ready to please a man.

"Ha!" Martha barked out a single laugh. "Seems you still don't know your place. Go ahead and look, then."

Emma didn't dare correct her master, but she did. She knew she was only happy for how perfect her master was. She looked at her master's pussy while she rolled her tongue around the outside of her asshole.

Emma gently applied pressure with her well trained tongue to simulate a male organ while taking in the sight of a vagina simply hand crafted by god to function in higher forms of sex. The kind of sex that Emma has nothing to do with and didn't need to think about at all.

Emma worked in deeper, earning herself a small moan from Martha, as she probed the soft and sensitive insides of her ass. Emma was **** to take in the sight of Martha's front. Inescapable view of nothing but a pussy just starting to get a little wet. The smell was also nothing that Emma needed to think about.

Emma felt a frantic energy fill her for some reason, and she pushed her face in hard. Nuzzling Martha's ass cheeks and licking deeply. It was her duty to help her master enjoy herself and reach an orgasm. She would help as much as possible.

The crack of the whip and pain across her ass caused Emma to pull back. When had her master gotten the whip? What had she done wrong?

"That isn't for you, stupid!" Martha lashed Emma's ass again. "Why are you getting turned on? Just massage my asshole you freak."

Was she turned on? If a woman said so, how could she argue. "I'm so sorry. I didn't mean to." Emma mumbled into Martha's back door while being careful not to brush up and taste her master's wetness. That was not for her and not for her to think about. "Please teach me right from wrong."

The whip did so and Emma let her pain fuel her need to make her master feel better. Some kind of alchemy was happening inside her, the wrongness inside her was being punished to the point that it became pure work ethic that helped her probe the anus more effectively.

The whip cracked again. "You are so gross. Getting off, even though you shouldn't have anything to do with sex. Should we see if the dildo fits into your cunt again?"

Emma froze. That was a cruel game her master had come up with to humiliate her. The metal dildo would be slapped and stabbed into her worthless fake cunt. The pain of the **** would drive her up the wall, but she couldn't deny that picturing a man doing the same filled her with wrong and stupid thought that she didn't want to think. "Please no."
