Ena Satsuki is treated like a toy by her brother, who's only interested in sex and spends all day fiddling with his cock instead of working. While one might think, "I don'm not opposed to being sexy, but I don't get turned on by my brother's dick," Ena-chan transforms into a slutty little sister who's just as insatiable as her sex-crazed brother once she gets going! She straddles her brother's raw cock, squeezing her tight pussy until he cums inside her!
