As usual, the brother and sister engage in raw incestuous sex. The brother waits for his sister to come home with a hard erection. When the sister finally comes home, things start with a deep kiss with their tongues intertwined. They seem to know each other's erogenous zones very well, and as they lick each other's genitals, their faces look both painful and blissful. Their love juice-covered tongues intertwine again, and as the cock slowly sinks into the sister's shaved pussy, the brother opens his mouth wide and gulps it down as if he is hyperventilating. The brother sucks the saliva that drips obscenely from his sister's tongue, who has a habit of sticking out her tongue when her uterus aches. After the raw incestuous insemination sex, he lovingly swallows the semen that was poured into his mouth.
