I bought A Date With Death Beyond the Bet (using Steam) when it came out and I downloaded the NSFW dlc with it (also using Steam). I played through it both starting after day 5 and at the beginning but can't get the nsfw scenes.
Make sure it's ticked and downloaded in your Steam DLC section. They are at the end of day 8 and 9 and very clearly marked, and there is no further set up needed. If they still don't appear, you can try verifying your files or reinstalling the game.
