A lot of sexual stimulation!

The Zamba works as hard as it can to pleasure this humans's extra-sensitive erogenous zones.

The ninja can feel at least 50% of her full arousal, so by the time the Zamba has successfully worked her up to 200, she is experiencing a constant sensation of the strongest orgasm of her life.

The ninja's sensei returns. This is it - there are only a few moments left. Fortunately, 200 happens to be the amount of arousal required to trigger her womb to release its newly incubated 'litter'.

As the sensei quickly says some words to her student, below her feet, countless Zamba larvae are escaping their mother's womb and leaping into their father's arms.

The Zamba didn't get to convert the human's rectum into a secondary Zamba incubator, or advance her erogenous zones to such **** levels of zygyzax that she is left in a permanent state of arousal, and **** to seek out more opportunities to mate with Zambas, but it was still able to reproduce.

And then, suddenly! Searing white-hot pain as razor-sharp wind cuts at its tentacles and body. It quickly retreats further down into the soil with its new children, where they can safely grow into fully formed adult Zambas of their own.
