Considering somebody your sister or brother doesn't change anything in the real relationship. Either a person is by birth or fostering a mahram or becomes one by marriage anything else is just hearsay that is far away from the teaching of Islam.
Note that many people (including parents) consider somebody like family (and were mistaken as this was the first step to unlawful relationships), but as long as this person is a foreigner according the teaching of Islam he/she must be handled as such.
And homosexuality is haraam in Islam.
