Really being a lolicon isn't terribly important in context. (I'm a total otaku myself....so sadly I didn't have to look up the word, I completely wakarimasu)
The important part is that your friends/roommates are lying and screwing with you over a passion or interest. You need to clearly lay down your expectations of their behavior and the types of activities/action that are intolerable. Its also good to clarify the amount of teasing you are comfortable with (if any).
Unfortunately if you are all bound by lease, you may be stuck together. If this isn't the case, and behavior continues then you should find a new place (or replace your roommates).
