Runaway master

Dark Side of BDSM
Once Fawn reveals that she's part-time dominatrix in the local club, she would offer you to become her sub. You can refuse, but it would lock out progressing on her route. You can change your mind and agree at any time.

The following quests should be done first:
 * Feeding Cassie
 * Don's errand
 * Cassie's rescue

Once Cassie gets saved, Arlene would start attending the club, too. Try to ask Arlene in about trying to be her sub. She would refuse, saying what you must ask your actual dom first. Unfortunately, Fawn would vehemently refuse, no matter what you state as your motivation, saying that she thinks that people like Arlene represents everything wrong with the BDSM culture. She would be not in the mood to do any sessions, so just go rest for now.

Visit Fawn again in her condo, and ask her to try and act harsh with you by herself, to see wether it's really as bad as she thinks.

Fawn, too angry to think what she's doing, would go overboard with it, forcing you to say your safe word (twice!), and once she recognises what she just did, she would freak out. Once you wake up, she wouldn't be there, neither at her condo nor in the club. Talk with Arlene, then with receptionist, to learn that she run away to her family, at the Upper New Ark.

Obtaining the pass
You can't go into the Upper New Ark without a pass. But where to find one? Well, you can buy one on the black market in the New Ark Slums. By this point, you're likely already know the guy who sells junk; well, he also sells various counterfeit passes, each one costing you 100. If he doesn't sell you the pass, go see the hobo who asks for food until he tells you about the pass.

Which one of them would work is always random, and since they take away the pass every time you go past the security post, it may be different one the next time. If they bust you, they would fine you for additional 250, and still take away the pass. There's one-time event if you previously finished the Serial pervert quest, but otherwise there's no reason to get caught.

Fixing the pass
If you want to just make genuinely-looking pass and to not take any risks, you need to pay for another massage session with Lin Lin; after finishing, she would reveal what your passes are too glaringly fake to work, but she knows someone who may correct them just enough to make it through: the local tattoo master.

Tattoo master would require another 500 for his work, but would make the job done.

From now on, you can create additional passes by yourself, by buying them in the Slums, and then, by tinkering with them via Ink Pen, correcting them to resemble the genuine pass. Be careful, though: in order to do so, you must pass the Nimble skill check, with difficulty of 15+(3*Nim)%. If you fail, the pass would be hopelessly ruined.

Note that you must have a spare good-quality pass to make a new one, so be careful to always keep one in reserve; otherwise, you would need to ask tattoo master again.

Entering inside
Now, when everything is in order, you may go into the UNA. Be sure what the following conditions are met:
 * You are not armed;
 * You are not dressed inappropriately.

Otherwise, you wouldn't make it inside.

Finding Fawn
Where is the best way to find a schoolgirl? Of course, in her school, or, in this case, a college. Fawn can be found in the cafeteria on the first floor; approach her when you are ready.

Depending on your mood, you can either play nice with her, call her "master" in front of her friends, but then pretend it was a joke, or go full-meanie and ask when she would dom you again. She would defuse the situation either way, but her subsequent reaction would differ:
 * If you were nice, she would be surprised with your visit, before proceeding to apologise.
 * If you called her "master" only once, she would be upset, but admit that she kinda deserves it, then she would apologise.
 * If you went all the way with the humiliation, she would be angry and tell you to never do something like this again, or she seriously wouldn't forgive you, but then calms down and apologise.

Since you have no place to stay, Fawn would allow you to spend one night at her house, which would result in you two having a first night of love. Afterwards, Fawn would return to her condo, and resume her normal schedule.
