Those are all Matt and Sam s__ scene. Yes, in this version, Sam will f__k Matt to protect Liz from him. Follow the keypoints below.
Happy NTRS path. Sam should be ANGRY at MC. Here is how you make her angry:
1. Do not ask Liz to convince Sam about the fetish.
2. On the beach, let the sunscreen guy go all they way until Sam kicks him out.
Once done, proceed in playing v21 and v22 and make sure always select NTRS choices. At the last part of the version Liz will be alone in the hotel and she cannot contact Sam and Matt. This is when Matt will post all of Sam pics in his ShareSpace.
