Erin is the founder of the Free Use Club and fully believes in it's philosophy. You can easily find her either next the main cafeteria in Union hall where she often tries to recruit members and adepts, or in her room, #3 on the first floor of Campbell.
Blair is now an entusiastic member of the Free Use Club but, unlike Erin, she isn't full time devoted to the club. If you see Blair nude, she is available, do what you want! If she is fully clothed, take an appointment or ask for permission, like any other girl. Now Erin's roommate.
Rebecca is the newest member of the club. She is available almost full time, but doesn't want to be bothered in her room or around her room. Typically free use otherwise, but please respect her when she says no.
It's 2 in the morning, you are drunk and horny. You get to Erin and Blair's room. The door isn't locked. you get in and find Erin deep asleep. You put a condom and have sex with her, without bothering to wake her up. She took a sleeping pill and you leave after coming, without her waking up.
You walk in the corridor of the Faulkner complex and see Blair, nude, talking to a girl. You grab a condom, unzip your pants and from behind, sodomize her without her stopping her conversation.
You are in the cafeteria and see that Rebecca just finished eating. You get close to her and take out a condom. She replies "Not here. Follow me to the restroom". She leaves and you follow her. She enters the male restroom and removes her pants. You pull her on the wet counter and have sex with her after putting your condom on.
You find Erin in the library, in a corner. You remove her clothes (which is fine) and use a condom to have sex with her (which is fine too). But you decide to keep her panties. This is not fine.
Blair is talking with Erin. Both are talking about homework. You undress Erin and have sex with her (which is appropriate) and while you are busy, you begin caressing Blair or try undressing her. This is not fine, because Blair only plays when already nude
you see Rebecca walking in the Faulkner building and she gets into her room. You follow and pull out a condom. She kicks you out and you wait by the door for her to exit. This is not fine, because Rebecca doesn't play in her room, and that includes waiting for her by her door
