The story start with Marina teasing Kenji like always, but for today she isn't telling Kenji about netorase activity, but Marina past Sex Life. Before meets Kenji, she had sex with two guys, her first boyfriend, and an oldman (Ojiisan), His first experience with her boyfriend is not good, he sucks at sex technique, so Marina feels really hurt at first. But on the otherhand, her sex experience with Ojiisan is great, Ojiisan is good at sex, even she admits, he was the one who make her love sex. And then... Kenji teasing continues (you know the rest :D)
It's only abou 15MB so i know this gonna be short voice drama. Not bad for me since i am fans of this series. Marina's seiyuu really know how to do sexy voice, her teasing voice is great. And all naration, even Kenji voice is done by her! His "man" voice isn't really bad, but i always imagining this is Hiroto voice since her "man" voice looks like teenager voice. But, this voice drama only contain Kenji teasing scene, i was expecting Marina sex flashback, and that's not happened in this voice drama. If you can understand Japanese, and love this series, i recomend this voice drama!
