Five percent isn't that much. Maybe it'll go up later? And she's gotten two of these, so maybe there will be more if she tries things. They're totally all going to have to do with sex, though, aren't they? Hmm...
Consuming sexual fluids. 'Extracted'. Way to make it sound creepy, erogame. And the way this is phrased it pretty clearly expects her to have sex with multiple people at once sooner or later. On the one hand: Ooooh... On the other hand: Aaaah. Sex this, sex that, sex the other thing. It's fun, it really is, but it's vaguely worrying that her life will never be about anything else again.
(She ignores the nagging thought that her life was pointless and boring without the erogame. She had hobbies! Like... Food. Jogging. Soccer!)
...'Mad Inventor'. These 'perks' sound honestly pretty powerful. And she's supposed to get one at level 5?
