For over 30 years, several researchers in an underground lab had trained and developed their newest breed. They spent years splicing DNA and birthing their creations in an attempt to make fortunes on their newest product. Since the USA had completely allowed full experimental testing on human test subjects back in 2045, a few men and women had been working on this breed which is now almost ready for commercial production.
Meet EFAVA - the Experimental Fertility and Virility Android. This newest android is barely even an android - mostly a genetic human female, although with many sexual enhancements and a few features added to her body.
Her natural black hair and large blue eyes were bred into her for beauty, as well as large full lips and a small, upturned nose to facilitate air intake while throat-fucking large penises.
She is also equipped with the newest model of ERMs, the famous ERM-2.4, or Ejaculate Receptacle Mammaries. Mounted high on her chest, these exceeding large 36M breasts hang heavily down to slightly below her navel with upward pointing 1.5 inch nipples, about an 3/4 inch in diameter. The massive volume of the ERMs are designed to facilitate maximal 'milk' production, although in truth they do not produce milk, but a highly aphrodisiatic and nutritious supplement that flows constantly. Brilliant blue veins spider across EFAVA's creamy white skin, pumping the fluid.
As the name implies, the ERM is the primary nutrient intake system for EFAVA. They absorb semen in order to sustain the android. High surface area and length aids in collecting all of the semen possible. Semen also acts as a growth agent for her breasts, which then causes her to be able to collect more. Large breasts are an indicator of an EFAVA's age, and hence sexual experience.
She also has genetically bred ultra thin waist and wide hips, that cause her breasts to be clearly visible from any angle. Over half of each breasts is visible hanging down from the behind view. Her ass is not technically modified, although it is highly bred for desirable attributes, such as being large and soft, susceptible to any slight variation in movement, resulting in a tender bounce and jiggle. It is only intended for the enjoyment of the males (and females) who will use her. Her large, thick ass is supported by thick, muscular thighs that lead down to toned calves, as well as a very strong muscular system in her core to support her assets that might otherwise cause balance issues.
