Nine years after her AV debut, Aika Yumeno thought she had erogenous zones that she didn't even know about. Normally, she only feels ticklish when touched, but when she explores her "associative erogenous zones" that she feels when touched during sex, she finds out that her back and calves are erogenous zones!? If she says, "Why does it feel good? Don't touch me!", you have no choice but to blame her! After smearing aphrodisiac oil to heighten her sensitivity, she makes her whole body an erogenous zone cum over and over again! Aika Yumeno is broken... Free trial points available for the first time!
