Ringo lives with her boyfriend. One day, her sister Mikan visits her in her absence and sleeps on the sofa to wait her. When her boyfriend backs home and sees the sexy underwear, he mistakes Mikan for Ringo and licks her tits and clits, puts his hard cock into her wet and tight vagina until blows his load inside her in the cowgirl sex, with the better feeling than usual. Just then, Ringo backs home. He is surprised and looks again at smile Mikan.
