First, it's time for some body mods

"I... Err... I'm worried that my clothing got ripped down there. I want to do it in privacy." The human woman says to her instructor above.

Don't worry, your clothes are still fully intact. But I will be keeping your panties. The Zamba thinks to itself.

Anyway, that should hardly be the human's primary concern right now. It's certainly not the Zamba's. It only has one major concern right now, and that's that while this woman does look particularly breedable, with her wide hips, thick curves and huge breasts, she still isn't the perfect incubator for more Zambas. No, to be perfect, this body still needs a few adjustments.

Fortunately, the Zamba has evolved to be capable of exactly that, when it finds a mate. Four specialized tentacles with sharp, pointy ends find their ways to the human's nipples, clitoris and anus. The human would find this bit rather painful if she could feel anything, so it's really rather a kindness that the Zamba has ensured that she can't, it thinks to itself.

The Zamba can measure, with frightening accuracy, several details about this human female body it plans to turn into the perfect breeding partner. These details include things like the size of her breasts (G cup, in human measurements), her total weight (65kg, in human measurements), the dilation of her anus (0cm, in human measurements), and the zygyzax of her nipples, pussy and anal passage (all 0֍).

There's no direct English translation for zygyzax, but it refers to the tendency of that particular body part to draw ki out of the host's body as it is physically stimulated (this tends to cause inhumanly **** pleasure for the recipient), in a form that is easily digestible and very nourishing for species like Zambas.

The sensei leaves, and the trapped human pounds the soil above.

"AAARGH! That fucking woman! I can't believe she beat me again! I'll never get her to stop calling me baka at this rate... And if I can't beat her even once... What chance do I have of succeeding at the Trials?!"

Zamba don't feel strong emotions of triumph, but this particular Zamba still feels something like deep satisfaction at the knowledge that this human's body has had its G cup breasts improved to P cups, and its arousal has increased to 50ㄶ and is already oozing copious amounts of vaginal juices (a human would normally orgasm at around 100ㄶ), and she is still completely unaware that anything has happened at all.
