In a spontaneous moment, this married sister initiates a quick, dirty encounter with her brother. She takes his long, hard dick in her mouth, sucking it eagerly, slobbering all over it. He responds, pushing her down, fucking her face, before she climbs on top, impaling herself on his thickness. She rides him hard, her wet pussy sliding up and down his shaft, until he explodes inside her, giving her the quick, sloppy fuck she craved.
