If you really want, I can put in an option for Penelope to not accept any customers permanently, so she can be kept for a player. There is already an option to not pimp your companions - it is optional and you don't have to do it. But the rest of the brothel will work as it is. A lot of people wrote me that they want something like this in the game and I try to cast as wide range as possible for everyone to play the game. If I focus only on one type of fetish, people would not play it.
Also, If you just lock player's action into one, specific role, it would limit the story telling. I want Penelope to be kind of player's agent and ticket in Freeport's noble society. She would basically befriend local ruler and his family and it will open up for the player. If she is locked in player's harem and forbidden to interact with others, how ill she do it?
I get the idea, but still see it from a different perspective. Some people love pimping and cucking, others find it disgusting and don't enjoy it at all. The ntr crowd is a loud minority.
Right now the pendulum is swinging way too much to the cuckolding side. There is hardly enjoyable content for harem lovers for the time being on the island. I'm also not the only one saying this.
I know that pimping the player's love interests is optional. But all those special roles like greeter and so on also require them to display themselves naked in the public. You can go even further with allowing them to offer handjobs and blowjobs, but all of this is content for the ntr crowd. (Why do they have to be the player's love interests he brought with him? Why it isn't possible to assign bought slaves to these public roles?)
Just think a moment about it: what exactly is for harem lovers to do on the island of Freeport for the time being? All you can do is fuck some random saleswomen in the back street. While all the other content is for the ntr crowd. Like this you'll be losing fans. Because this is completely different from the gameplay on the mainland.
You've already added two different personalities for Penelope to be trained. Why not making one (the "wild" one) for the ntr crowd, and the other more tame one for the harem lovers.
I don't have a huge problem with the brothel, but special characters like Penelope should be optional to pimp out and also offer a completely different route. I'm glad, that you want to implement an option to keep Penelope for the player.
She can still interact with Freeports patrician society, after all she's a noble women, too. And these people are rich and bored. They love doing conversation with equals, gossip around and since the island probably isn't that big, they already know each other and are happy to see a new face. She doesn't have to sleep around like some hoe in order to introduce the player character to these people. She can still be a valuable asset without being a hoe.
Penelope is another love interest actually and a lot of people will not like to pimp her like the rest of the slave women. Also really check out the content so far on the island, it's like 95 % ntr, while only a few random saleswomen are for those, who don't like to play as a cuck. This is totally unblanaced and so far you only please the ntr people.
Your winning formula so far was creating this nice little fantasy world, adding a male mc, who was able to accumulate a rather large harem, to corrupt women and to impregnate them together with some role play elements and lots of different quests (hours of gameplay so far and I wasn't bored by the content at all - there is even lots of unfinished business on the mainland left like the female village shop owner or the tavern owner and not to forget the unfinished content in the temple and so on).
But in Freeport there is none of that content so far, most of your fans used to enjoy. Instead we have this new game episode in Freeport for people who enjoy to make their mc to lick cum out of whores after clients used them. Seriously wtf?! I know this is also optional, but I can only adivse you, people who demand more and more cringe content, will not improve your game, but will make a niche shitshow out of it.
