Mishnah Yevamot
A man is permitted to marry [the relative] of a woman [whom he has] raped or seduced. He who rapes or seduces [a relative] of his married wife, is guilty. A man may marry a woman whom his father has raped or seduced or a woman whom his son has raped or seduced. Rabbi Yehudah forbids [marriage] with a woman whom one’s father has raped or seduced.
