Ever since Hikaru's sister started middle school, life around the house has been uncomfortable to say the least. For his cute little sibling, Fuuka, went through a massive growth spurt, making her exceptionally tall with monstrous breasts to boot. What's worse, the girl is determined to have her beloved brother take her virginity and have a baby with her! Will Hikaru manage to keep his busty sister at bay long enough for her to graduate to high school?
Both manga are based on the brother/sister incest relationship, and also that both the brother and sister have feelings for each other rather than one sided love. both are ecchi, with Oniichan Control being quite light hearted and funny, and Rika being more about day to day life.
