Hello Shadow2205,
It seems you’re missing the Parasite Worm naked and the force scenes for the Jellyfish, Leech and Egg Fly.
For the force scenes you need to reset the lewdness level on Rumia’s shop. For the naked worm you’ll have to cure all parasite worms and get infected again. The scene is triggered when you sleep naked, but after 3 times, it changes to the big worm.
