A vlog by a girl who originally just wants to make her gothic older sisters feel loved and sexy, and winds up being coached by her anonymous userbase into seducing her own older sisters, who are conjoined twins (two heads on one torso, nothing duplicated except the spine, one arm and one leg controlled by the twin on the same side), who also have two fully developed prehensile tails growing out from the tailbone (complete with all systems fully developed, skeletal, muscular, nervous, etc. each tail is controlled by the twin on the same side, their tails can, and will, be used like tentacles for tentacle sex), genetic disorders that makes them incapable of producing pigment (type 1 Oculocutaneous Albinism, completely colourless skin, completely red eyes), or hair (type 1 Alopecia Universalis, they wear wigs), and four additional fully-functioning breasts along the milk lines of the body, that is, an additional breast below the natural breast, and another one below the additional breast, making six in total (type 1 supernumary polymastia, three breasts to each twin along the same side), the vlogging sister ultimately records a homemade incest porn streamed live via webcam, without either of her sisters knowledge.
