Let the breeding begin!

The stuck ninja waits patiently for a good 90 seconds, during which time the Zamba can get a lot done.

First, a small tentacle invades the human's anus, probing deep inside to make sure that it can stimulate every single nerve in that delightlfully tight anal passage.

A second, tentacle eases its way into the victim's vagina. Once nice and deep, this one bulges and widens to three times its original girth, ensuring that the vagina feels incredibly stretched and extremely stimulated with every energetic thrust of the invading appendage.

Next, each nipple receives its own penetration from a specially evolved, narrower tentacle, which stimluates and widens these spots, encouraging them to store delicious, nutritious ki in the form of rich, creamy breast milk.

Indeed, this doesn't take long at all, and by the time that the ninja is trying to perform her technique again, vast quantites of her ki have been drawn away from her spiritual circuits, and physically manifested as breast milk and other bodily fluids.

The attempt to perform the technique fails, just as the Zamba had planned. Instead of releasing her ki as rotational momentum, she simply releases vast quantities of ki-rich breast milk and urine, which the Zamba hungrily devours.

The human female's body nears its first orgasm. But the Zamba doesn't want all this sexual energy that it is building up inside this human to be disappated by a boring old orgasm. No no no. Fortunately, it has another ability that it has up its sleeve, ready for just such a moment. And so, without further ado, the Zamba is the one that climaxes first, unleashing a torrent of thick, hot ki-infused semen into the ninja's womb.

As the human's belly bloats to a huge round size, thanks to her uterus being blown up like a water balloon by Zamba cum, the ki from that ejaculate manifests an important heart-shaped rune onto its host's big round tummy. This mark is permanent, and its effects are twofold: Firstly, this human's uterus has been 'reprogrammed', and instead of working to grow a single egg into a single human baby over a course of nine months, it now works to grow countless Zamba larvae from a huge number of its eggs, over the course of a few minutes.

The second effect is also very useful - when this human orgasms, as it is now starting to do, it does not stop climaxing until the pleasurable stimulation stops. Instead, it just keeps on experiencing a stronger and stronger and stronger orgasm as the arousal and pleasure continues to build ad infinitum. This is important for the Zamba, because the sexual energy redirects the human's ki to its nipples, vulva and anus, where it can transfer this nutritious energy into its new 'babies'.

Still creating breast milk, and now with a womb pumped full to the brim with cum, the human weighs 88kg. Her nipples, asshole and clitoris are developing nicely, and will be permanently extra-sensitive for the rest of her life, and will drain her ki away from her spirital circuits whenever she gets horny.

Her arousal is at 160ㄶ - already 60% stronger than the normal human orgasm experience.
