mao, a girl going through a sensitive period. fuka, a female college student and tutor. the two of them had the same feelings for each other but didn't confess... fuka couldn't stand mao, who only did innocent pranks, and kissed her. rising lust turns the two into naked women... they stick their translucent skin together and lick each other's wet pussies... the two seemingly pure girls spend time melting in a lewd and erotic lesbian lesson...
