Wife forced scenes

[grasshopper]

Hey guys was wondering if anyone can help me find mainstream movies with scenes where the wife/gf has to sleep with their captor(s) to help her family or partner escape from captivity. I can name a few to identify what sort of scenes I am talking about:

'Straw Dogs' (1971) - Susan george is forced upon by one of the captors but she does not resist.
'Penthouse' (1967) - Suzy kendal and her husband are held captive by burglars in their hotel room. They have fun with Suzy.
'Open Season' (1974) - Cornelia Sharpe and her husband are kidnapped and taken to a cabin. Cornelia ends up sleeping with the men to save them selves.
'Trapped' (2002) - Charlize Theron seduces the bad guy that keeps her hostage, to save her family.
'The last house on the left' (2009) - Emma pretends to seduce Francis.
'Dead Calm' (1989) - Nicole Kidman sleeps with the kidnapper to save herself.

So can anyone help me find some more movie with this kind of scene thanks.
