In our home, the skewed older-advanced common sense typical of the countryside has become 'little sister belongs to big brother.' In the closed-off countryside atmosphere, no one blames them, and our parents don't stop them. Even when they're studying, under the dining table, or standing in the kitchen in a naked apron. 'I have to listen to what my big brother says,' she says, and though she's shy, she naturally opens her legs. Her innocent expression as she feels pleasure amid her bashfulness, and her body is unconsciously overly erotic. At first, they're confused, but before they know it, they find their chemistry is perfect and they're hooked. 'The madness of a closed space' x 'a sweet, never-ending countryside summer.' Missionary position, cowgirl position, doggy style, sitting position, blowjob, titjob, handjob... cumming inside, over and over again.
