Blackmailed

Cassie has made a serious mistake, she wishes she could say she was drunk, but she knows she wasn't, she has cheated on her loving husband. The only consolation she has is that she wasn't caught, no-one will ever know.. or so she believes until she receives an email with a picture, a pic of herself getting it from behind, but she soon learns the picture can vanish, if she can seduce her step father!
