Sisterly love forbidden by a standing penis!! It doesn't matter if you're male or female... it's always a lesbian story between sisters!! Sisters aiming to be idols. They had a secret that they couldn't tell anyone: they were 'hermaphrodite sisters' with penises in their crotches. They loved and comforted each other's penises. The dizzying perverse act... it was a natural way of life for the two of them.
