In the story. Natsuki Takeuchi’s husband has had an accident and he got crippled. He cannot bear children anymore so they convene that in order for Natsuki to get pregnant it will be the actual husband’s Father the one to impregnate Natsuki, because better than a total stranger huh?
However, they didn’t expect grandpa to go ballistic, and by the end, she can’t give up the cock.
I have mixed feelings about this movie, but seriously though, how can glory quest not find a better way to use a woman as stunning as Natsuki Takeuchi? Or maybe the goal was to gross the viewers out a little, in which case it’s a good job.
