When I first started college, I moved in with a guy named Rob. He was a pretty cool guy, really easy going. The only issue was that he was a bit too easy going. He would occasionally walk around the apartment naked, and had no issues with being open about sex. It was weird at first, but I got used to it pretty quickly. I actually appreciated his relaxed attitude, he didn't make sex a taboo thing and I think that's a good mindset to have. We would occasionally discuss sex. What we liked, past experiences, and so on. It was nice to be able to discuss that stuff with someone.
I knew Rob was Bi. He had brought home dates occasionally, sometimes women and other times men. I had no issue with that, as long as they weren't too loud. I hadn't brought anyone home yet, a since I wasn't having much luck in the dating department. I'm not exactly bad looking, just shy. My last relationship had started when I was 15 and ended right after graduation, so I hadn't had much experience.
One day, I came home early from school and found Rob on the couch, watching porn.
"Dude, what the hell?!"
Rob jumped, clearly not noticing that I had gotten home. "Shit, sorry man, I usually make sure I'm done before you get home." He hadn't moved to cover himself up, and was still slowly stroking himself. I glanced at the porn on the tv, and felt myself getting hard. "You're welcome to join in if you want."
I froze. I knew he was easy going, but this was something else.
