Here is the consensual non-consent scene to which I was referring. We did this scene about 15 years ago. Parts were emotionally brutal. It drastically changed our relationship for a few years and gave my friend nightmares.
About 15 years ago, my husband and I and an experienced couple we occasionally performed severe S&M scenes with did a scene that included a home break-in with kidnapping and sexual abuse but not intercourse or rape because we thought being that close, the wife would recognize who was raping her.
The wife wanted to do a consensual non-consensuality scene (no safeword, and no way out for her) about 15-16 years ago, the details of which she was never to know. About 15 years ago her husband, my husband and I, hooded and kidnapped his wife in the middle of the night. We did not want to cause any injuries. We drove around for a couple of hours in a rented car and finally brought them to our house for the scene, which was mostly one of bondage and sexual abuse. We did just about anything sexually with her body that came to mind except intercourse (because we thought she might recognize her husband) for almost 24 hours before she was brought back to her house, still hooded and finally released. When her husband told her that she had just experienced the non-consensuality scene she wanted and we had planned more than a year earlier, she said she would NEVER do that again because she was absolutely terrified, was under severe stress and put on a real struggle, crying bitterly as she was anticipating the worst, feeling powerless and fearing for her life.
The scene went exactly as planned, but the consequences weren't so good. We are still good friends today but we don't look back on this with any joy. There are limits, and this went beyond them.
Be careful with home invasions and kidnapping scenes. Aside from taking a lot of planning and being hard to pull off, there can be bad feelings afterward.
