After finishing the game (including the special event), what i can see is:
- Harem
- MILFs (the one that giving you "ara ara" vibe)
- Tsundere
- Kuudere
- Dandere
- Voyeurism
- Light BDSM-ish (Master and servant type of conversation, and vice versa)
- Cunnilingus
- Anal
- Creampie
- Boob Job
- And some very specific stuff that i cant name it correctly (cat girl, tomboy girl, etc)
Its all i can name it, but i believe there's more than that. I just dont know whats the correct term for it. But, I can assure you that there's no NTR, pregnancy, or inflation here.
