Let’s Raise My Female Cousin Who Woke up from Vegetative State after 10 Years into a Meat S*ave!

When all of my relatives died after an airplane accident, the sole survivor who entered vegetative state is my female cousin, Mifuyu-chan.
To wake Mifuyu-chan up, I have acquired the knowledge of medical science. For 10 years, I have spent time everyday trying all possible means, but on that certain day, due to the influence of getting drunk, I violated the unconscious Mifuyu-chan.
Being charmed by Mifuyu-chan’s body, I decide to use her as an onahole everyday.
However, Mifuyu-chan easily wakes up next morning.
8 year-old pure mind in a 18 year-old mature body.
This is a story of exploiting such an unbalanced beautiful, ignorant girl – Mifuyu-chan, to erot*c things.
