Your point being Lin wants to, so it's not rape, so it's not netorare.
This could be argued about, given her behavior and the fact she is nothing but a slave according to the lore, but you being the one who choose what she wants i guess you know better.
While i jack off to lesbian porn every now and then too i wished it could have been avoided in your game. I gave my opinion, you took notice of it and that's about it.
I still consider you did a great job regarding the character.
(Now if i was the manager of the hotel Maria would be kindly asked to leave cause i just don't click with her... Good thing i'm not i guess)
And again, i consider you do a great job. I was actually surprised to not have my word to say at this specific point, given that i was given the possibility to tell her to back off previously.
I consider your work even more impressive now that i know you work alone. So yeah, congratulations, you're doing great.
