Uhh If this is about your roommate. One watch them in bed. Two take his BF's Challenges. Three Improve your relationship with the BF through the challenges. Four eventually you'll see Allison jacking off alone tell his BF. Five start a relationship with the both of them. You'll be in like a polly relationship with both of them. The BF will be more of a Dom relationship & Allison will be the Sub relationship. Atleast that's how it is in my Run. But it's a GF for me, and I'm a dominant sadist.
If you one to change Dorms, and you're playing the up to date version of the game. Them join one of the new fraternity/sororities. Eventually when you become an official member. You'll be able to move into one of their open Dorms. It's going to cost you though, so make sure you have the money to afford it. I haven't reached this point, but I believe you'll be able to room with your Best friend in the frat house. If you're the same gender, or you turned off the gender norms in your options.
I hope this was helpful.
