A decent effort

You lower yourself in front of Xyryx, and when the signal is given, you dive in with gusto. You run your tongue up her labia, delivering a kiss to her clit as you reach it.

Soon, you hear moans of pleasure from above and the pussy in front of you grows damp. Her fluids taste interesting. Similar enough to a human woman's to be recognisable, but different enough to be obviously from a different source.

You push in deeper, your tongue pushing into her vagina as she continues to moan. Soon, you hear a loud moan from your mistress, and realise you have probably just lost, but you continue to work until you draw an orgasm from Xyryx.

A torrent of fluids bursts forth, and you have to swallow it to avoid inhaling it. You pull out, face getting splattered as you turn towards Mistress. She frowns at having lost, but doesn't look angry with you.

Mistress hands over her money, having a short, but good natured, conversation before she leaves.

"I am... disappointed you lost," she says as she leads you home, "but I will not deny that your opponent was extremely skilled. I will not punish you for your defeat, but I want you to practice. You will eat me out every morning before breakfast until I declare that you have reached a sufficient standard."

"Yes, Mistress."

"Good. Now, once we get home, you are to go and prepare dinner for yourself, and then feed the incubators."
