A little vague with your question, with no idea what your missing hard to give you advice.
There are already guides for sister. so I'll ignore all those.
So if it's your party members you get some by doing the DLC hot spring story. after you reach a certain point in hot spring (don't ask me how far idk) you can also get a scene with glasses and medic at the ocean. You can also get a wet dream scene for all party members and elf by having max lust and sleeping (not with your sister), I don't know if these are tied to DLC story progress or not. The amount of scenes each girl gets isn't balanced. I think it's Glasses > Medic > Sword > Elf it terms of number of scenes.

if you aren't getting scenes with party members while doing the DLC, I would suggest every time it prompts you if you want to train/help them or end day, to spend time with them.
