For even more pleasure, stimulation, irritation, punishment, or torture, two metal egg-shaped devices are inserted into Alexandra’s nipples and breasts. These devices end in numerous tiny wires, which deep travel into Alexandra’s breast milk ducts, reaching deep into her breast tissue. Being completely made of metal, these devices allow for extremely heavy and painful shocks and vibrations from within Alexandra’s massive breasts, significantly increasing the different ways she can be pleasured or punished. Due to this function, and often used by Lumina to cause pain, they are also called pain plugs. After full insertion, her nipples are stretched extremely, making them even more sensitive.
Alexandra’s nipples are then also injected with the sensitivity serum, severely heightening the nipples sensations and making them swell heavily, increasing pressure on the plugs.
To properly trap and seal the plugs within Alexandra’s breasts, the nipples are then pierced with a metal bar, onto which then a barbed ring is threaded on, that heavily presses its barbed spikes into Alexandra’s nipples, as well as around the areola, making them extremely sensitive, irritated, and painful. Even the slightest movement or swivel causes burning flames of pain to strike through Alexandra’s upper body from the barbed piercings and metal within her nipples and breasts.
