Elfriede Jelinek's The Piano Teacher comes to mind here - Erika is definitely oppressed by her Mom and the burden of respectable life, to the point that Mother intrudes on everything she does, although the girl's got her own home. It's not a sex story in the ordinary sense, but Erika's raving dreams about being liberated through a sadist lover who will tie her up, rape and crush her like a lemon are both frightening and funny.
