A good number of these are based on gacha scenes but with different scenarios to how they play out.

There's this bride themed Hebiko CD LGD-70072 LGD-80072 that came a bit before her RPGX bride scene.

LGD-70053 LGD-80053 is another one based on a gacha scene. This one came before Tokiko's first TABA NTR scene or it was shorty after the release of her being captured by Gisuke. It looks like Lilith does a lot of prototype or alternate version ideas for real scenes made into drama CDs. https://www.lilith-soft.com/store/product/LGD-80053/2079

This LGD-73037 LGD-83037 is another one with Tokiko being captured. I'm not sure if it shares the general idea as the one above, but it does share the TABA art.

LGD-73463 is secretary Ingrid. Looks like another alternate/prototype of a gacha scene.

ZZZ-00043 is adult Yukikaze raped by tentacles. Do you remember when adult Yukikaze's first unit had tentacles in her artwork, but the scenes were only vanilla? Something tells me that this was originally going to be the scene, which is why the art depicting her being attacked by tentacles was already made. Pic related.
