Forgive me if I'm reporting something someone else already has; I searched the thread and didn't find anything. I also am not sure whether Backhole is on F95, so if someone is a patron, maybe they can pass this on.
If you choose to play the game in English, there are a couple of spots where the translation from Spanish to English didn't get put in the game. First is if you talk to Evelyn when you first arrive at the mansion. If you choose to Tease her and tell her you're a Gigolo, the fourth line of dialogue that the MC speaks is still in Spanish.
She says, "Perdona, solo te vacilaba un poco. Me llamo [mcName], y tenga una cita con el Sr. Collins". While not a literal translation, the English would probably be rendered something like, "Sorry, I just took a little detour. My name is [mcName]. I've got an appointment with Mr. Collins."
The second instance I found was when having Rose give you a blowjob back at her place. The MC thinks to himself, "(Vamos a ver hasta donde es capaz de tragar)". Translated into conversational English, it would be "(Let's see how far she can take it)".
