This fourth layer, on top of the enhancements, comes in the form of a thin web of touch sensors, applied over Alexandra’s entire encased body.
Function
Leaving no spot of Alexandra’s body uncovered, this web makes it possible to forward an extremely detailed artificial sense of touch to Alexandra. These senses are fare more focused and detailed than that of a human, all while still under the full control of Lumina.
A similar web is also spread on any surface within the fake vaginal cavity inside the vaginal insert, ensuring the tiniest touch or penetration floods Alexandra with immense pleasure and arousal.
Even when covered by the final layer or any of the shells / disguises, this web of touch sensors give Alexandra a superhuman sense of touch. She’s able to feel slight changes in air current and can even recognize if a spec of dust lands on her encased body. The detail and intensity of these sensations are so extreme, Alexandra only very slowly manages to handle the onslaught of sensation. Even after having somewhat adapted, the tiniest touch is still capable of easily making her jump from the sheer burning-like sensation and overwhelming detail the feeling causes her.
But all of those signals are under full control by Lumina and only available to Alexandra if her AI Mistress allows it.
Again, this layer is also encased in another layer of the smooth black latex solution, as the armour and third layer.
