I made use of the three stars in Demi-Human right away. I began sketching out the shape for a merman. It would not as resource heavy and bulky as a centaur. It was a model that would not take up as much space as a lamia as well. All of my teammates were in. I had three Adamu, one Okoth and one Najja on the team. The Najja had red hair and a pair of gray eyes. His name was Devon. The Adamu treated him as the coffee boy although he was the one who was supposed to install the energy system. I was not going to rock the boat on the first prototype so I left it alone. I got the steel needed and got to work working on the creating the skeleton. The game gave me a step by step walkthrough and graded me on how accurate I was being. It gave me three tries on each step to mess up before the fourth one was locked in for better or worse. I let anything C or higher go pass regardless of when it happened. This was just a prototype. If approved, it would be mass produced. Once that was done, it was time to place the caging for the mechanic rigging and the computers.
That also went well enough with the game telling me how to do it. I was also responsible for the rigging of the lube, USB Port and the audio jack. I did pretty okay on it. A sense of accomplishment was growing inside me. The actual jack and lube container would be added after. I also had to rig the dick to emerge from what would be the cloaca. I decided to go for a dolphin model. It was obviously going to be for those with more exotic taste. There was a real chance that it might be too niche for the mass consumption of the people that could want a sex android, but I was going to go for it anyway. I then let the others do their work in the body. The two programmers had a brain shaped computer that they put in the cranial cavity. The lube and synthetic cum containers was placed and the lower abdomen. The two hydrogen cell batteries were placed in the chest where the heart was supposed to be. Because water and heat were the byproducts, the water filtered into dick with the lube and synthetic cum through a separate container. The merman would be able to take a piss when needed.
Making use of the space, the right pectoral was where the USB Port was being placed. It would have a water tight covering to keep it protected. The back of the merman neck was where the extendable audio jack and plug was going to be. It was also going to be made water proof. With everything in place I let the programmers give it a dry run to make sure the tail could bend and execute the swimming function properly. It took a few tries and several skeletal readjustments to get it right. When it was finally gotten right, we then finished putting in all the armored plating over the frame and welding everything shut. Once that was done, we made sure everything worked as well. They did. The lower back was were the plug for charging was. The next step was to put the synthetic skin on. I wanted to have a sandy skin tone. We put it in the machine to put the skin on. Possessing 14²/cm² skin tactile elements, meant it would have a greatly heightened sense of touch. For the tail, I wanted to make it a soft coral color. All the scales were synthetic material that looked similar to the real thing. It had pink hair and dark blue eyes.
Now that the skin and scales were finished, we had to test it out. It was just a sex android prototype, so it was not very intelligent. It was a weak A.I that had some limited memory. We took it to a private pool to swim a bit. After a few hours of watching it swim, we collected it. The team then had Devon test out the sex feature. He did not want to do it, but the Adamu browbeat him into going in. We could watch from a separate room. To add to the growing humiliation, they gave him a yellow speedo and flip flops. He got in the room and sat at the rim of the tub the merman was waiting in. The merman looked at him and waited for Devon to make the first move. Devon told the merman to present its cloaca. The way it worked was the dick was seven inches buried deep for penetration. The dick could protrude five, seven and nine inches from the cloaca by request. Devon pulled his speedo down and got in the tub. "Ride me." he said. The merman moved its body in the tub to cover him and wrapped its arms around him for added leverage. The merman connected with Devon's length and rode him.
