Fuck medical ethics, it did not take long for the genetic engineers to figure out what to do. Tracy is not their first attempt, some of the others turned into green slime in the test tube, but she is the first that all the scientists at the research institute wanted to fuck. Although some of them did have a good time with the green slime. After a few experimental gene mutations, they came up with ever smiling Tracy, the beautiful girl with near zero IQ, who is open and willing to do anything. The corporate sponsors came to see. And fucker Tracy. They ordered more specimens, more clones. Now the institute gets plenty of funding. And all the poor sods in hospital waiting for stem cell technology to cure them get nothing. It is all down to sex. Tracy, genetically engineered to be happy to do everything, on video.
