So v1.12 onwards has a lewd streaming mechanic. So her stats are seperated into affection for player, affection for landlord and corruption. Corruption drives dressing sexier etc. It also drives some dialogue of hers. And corruption increases if lewd comments aren't deleted on her videos. And once her corruption is high enough she does lewd streams where the landlord does donate under an anonymous username.
I will take your reward idea under consideration tho, seems like a decent suggestion!
