After the control unit has been inserted into and inflated inside Alexandra’s womb, as well as the dose of the Sensitivity Serum has been injected, a massive rubber phallus is pushed into her vagina, stretching it out substantially. The phallus is long enough to push up Alexandra’s womb slightly and reach her cervix.
Function
Before the vaginal intruder is inserted, a few small, slower acting, doses of the Sensitivity Serum are injected into various spots of Alexandra’s inner vaginal walls and labia. Once the device is fully inserted and secured, the serum will cause the surrounding tissue to heavily swell and become much more sensitive, compressing tightly around the gigantic intruder and making the tiniest movement extremely arousing and painful.
The tip of this device acts like an anchor mechanism and is pushed past Alexandra’s cervix, making it expand flat against the inner uterine wall, trapping the entire device inside Alexandra’s vagina. This part, inside her womb, then also connects to the womb core.
The outer end of the device has a flat base, covering Alexandra’s labia and her clitoris. Furthermore, it features a central hole that travels down the inside most of the vaginal insert, the inner walls lined with flesh-like silicone, resulting in an identical feeling to the inside of a real vagina. This space is usually compressed tight together, but can be opened up by Lumina, essentially giving Alexandra a sort-of fake vagina back, even allowing for penetration deep inside. Any sensations from this inner cavity are directly fed into Alexandra’s nervous system, letting her feel the tiniest stimulation. Any reactions or reflexes are mirrored within this fake-vagina, compressing the surrounding fake-flesh or letting it twitch. Furthermore, any sort of penetration is heavily amplified by additional movement, thrusting, and shocks by the entire vaginal dildo. Should Alexandra actually have any sex and anything be inserted into this cavity, the sensations of the fake vaginal wall and clitoris are so extremely sensitive, they will immediately overwhelm Alexandra and send her into a pleasure and pain-filled delirium.
The flat base also features numerous regularly placed holes, through which countless ring-piercings are inserted and through Alexandra’s vulva, that once closed, lock this side in place as well. These piercings, when inserted are initially quite warm, and when cooling down, shrink substantially, fusing closed and hold so tight, they cannot be removed without surgery.
Furthermore, over Alexandra’s clitoris, the base of the vaginal dildo has an opening to push the clitoris through. Once through, another piercing is put through the clitoris and secured to the base, stretching and locking it in place too. Then, the Sensitivity Serum is injected into the clitoris, causing it to grow substantially in size and tremendously increase in sensitivity. The section of the phallus base around the clitoris allows for powerful shocks to be administered, vibrated heavily, or making it feel extremely itchy.
The entire phallus inside Alexandra’s vagina has countless extreme pleasure functions, such as heavy vibration, individual gyration of different sections, a large number of metal sections that allow for extremely painful electrical shocks, and violent thrusting motions. It expands and contracts the entire device, as if Alexandra was fucked by a gigantic rod, thrashing around inside her entire abdomen.
