It was Rick, Jim's boyfriend (sort of). They weren't 'boyfriends' yet, but Rick had indicated that he wanted them to get more serious. Jim liked their relationship the way it was now; two male friends who just happened to enjoy having sex with each other. Why mess up a good relationship?
Jim had been experimenting with homosexuality since he had entered puberty. He liked girls, he just liked boys better. He was hesitant to label himself 'gay,' but he didn't feel like anything else fit. He couldn't see himself settling down with anything but another man.
Rick was gay, and was one of those guys that 'always knew' that he was gay. Even though they had known each other all their lives, it wasn't until they had gone to high school that they first started having 'feelings' for each other. While they both had other male partners, they both had a semi-exclusive claim on each other. Whether it was make out sessions in the locker room at school, or casual sex sessions at Jim's house, they had a caring and dymanic partnership.
"What's up?" asked Jim, blearily.
"Aren't you up yet?" asked Rick. "Remember, my parents are gone for the weekend and some of the guys are coming over. You promised that you'd help get ready."
