I'm sorry, but that is not correct for 14.1. Maybe for the upcoming release, but there is no sex with Nia on the love route in 14.1. Slave route has paizuri and blowjob scenes.
By that logic, you can do a threesome with Autumn and Autumn, and Felicity and Emma too, you can have sex with Kali in a library, you can lead Maria on a leash in public in a hospital, etc etc. You just need to play the whole goddamn game again if you want to see it again, since it's a one-time only, with no way shape or form for repetition.
By that logic also, you have hundreds of thousands of unique events with each character, since every single frame you see is different.
Do you understand why this is a dishonest counting method in this type of game? Or are you blinded by being a fanboytoy?
