Last night I saw a Japanese movie, subtitled in English and called "Wife to be Sacrificed." I like it. Plot spoilers follow, be warned.
It's about a woman who gets kidnapped and subjected to all sorts of goodies by her vengeful ex-husband, who seems a quite likable pervert except for his tendency to use children (which is not actually shown in the movie; only talked about and implied). YIPEE for excellent bondage, not your typical movie-bondage but actual bondage that would really hold somebody. Non-con wax scene, candle insertion, enema, lots of bondage, humiliation, rape. The wife eventually warms up to it all though, and even participates in working some non-con evil on a young couple they find in the woods. I definitely recommend this movie.
