Kekkou

Background

Not too long ago the scientist Dr. Drool created a new pet, to play with and learn his idea of social behaviour. In his lab he grew the little bioroid to his pleasing. As he is as brilliant in biology and genetics as he is crazy, the result was in his eyes more or less "perfect".

Perfect in this case is maybe an ill-chosen term, but Dr. Drool was quite satisfied with his creation. His goal was to make a sturdy and reliable design that still could pass more or less unnoticed in most situations. Over the three year lifespan, Kekkou has gone through over a dozen enhancements to the first concept. Not much has changed that can be seen externally but quite a few differences are hidden internally.

Body

Kekkou is more or less a humanoid bioroid with plenty of features taken from rabbits and other rabbit-like species. She is close to six feet long (almost as long as many human males) but is quite lean. Those two factors makes her look quite fragile in some circumstances. That is far from the truth, as she is quite muscular and extremely agile.

Muscles and skeleton

That brings up one of the enhancements: Her muscles are slightly stronger, per muscle fibre, than a normal human, but they don't use as much energy to function at high stress. They also have more reserves before getting tired and beginning to ache.

One thing that Kekkou was built for is high G movement and combat. Her muscles are very tear-resistant and almost all her tendons are close to ten times as strong as a normal human. Dr. Drool is very keen on keeping that fact a intellectual secret, as it is a very lucrative bio-material he ended up with mostly by accident. Adding a soft and stress-enhanced (tension) skin makes maneuvers in extreme Gs and high impact forces possible, as her muscles flow and bend around the bones and the skin keeps most things in place.

Her bones are slightly stronger but much harder than most mammals, and they are perfectly smooth. All to add to the damage-resistance during high G situations.

Circulatory and respiratory systems

Under the surface of skin and muscles there has been some serious changing. To accommodate and in some situations keep Kekkou alive, both the blood stream and trachea has multiple connections for the blood and air flow. (More on that later.) The circulatory system is symmetrical and has two hearts to pump the blood. Both sides is perfectly interconnected to create a backup should one side fail.

Genitalia and gastrointestinal tract

As most of her tissues are quite elastic, her vagina can accommodate some of the biggest appendages there is. When she was created, Dr. Drool had a clear idea of what he wanted from his construct so he designed her pelvic bones a bit differently from norm. Her pubic bone is actually made up of several separated parts, more like an ancient stone bridge is constructed. That makes her pelvic area able to take insertions up to and above ten time the average.

Her digestive tract is redesigned completely. She now has a very short oesophagus that shortly after neck continues in a combined stomach and intestine tube. It goes in an almost straight line from throat to anus. She usually feeds on a special nourishing paste that gives her all the nutrient and energy she needs, and that paste is completely absorbed through the wall of her combined stomach/intestine. That makes the tract perfectly clean and she can be sustained without problems for months at a time using just the pastes.

A recent discovery is that she actually can live off of semen and that she sometimes on unplanned trips away from her food pastes has come to live from semen alone. Semen has many of the same properties of her specially designed foodstuff, in the regard that she keeps her gastrointestinal tract clean and that she produces no faeces from either one of them.

Another recent discovery, in a purely sexual concept, is that he can take even bigger things "up her ass" or "down her throat" than vaginally. That is from the fact that there is no end, so to speak, as she has been seen take penetrations that "goes right trough her" from anus to mouth. And as her air pipe is redirected on both sides of her neck, she can continue to breath while being deep throated.
