Forbidden sisterly love connected by an erect penis! ! It doesn't matter if it's a man or a woman... A lesbian story between sisters forever! ! Sisters aiming to become idols. The two of them had a secret that they couldn't tell anyone, that they were "futanari sisters" with a penis growing between their crotches. Love each other's penises and comfort each other. A dizzying perversion... It was a natural activity for the two of them.
