Birth of the Tentacle Fiend
Infected by the sting of a Japanese mosquito, a woman grows a penis and feels compelled to use it on her friend/sister/daughter. After that, things start to get a little weird.
Be warned that the events in this story might be a little shocking to those uninitiated in futanari (dick-girl) and tentacle sex. But trust us, this shit happens all the time in Japan.
You can choose the names of the girls and their relationship to each other, as well as the initial size of girl 2's breasts...
