Fun times with a Friend

So with the program I'm on, we had to do some switching around with roommates. I have a friend, who I'll call Chris who I am particularly close to as friends because we have similar interests, the only difference is, he's straight. He most recently got out of a relationship with a girl, and I was there to support him. Let me tell you a little bit about Chris. He's also 18, probably around my height (5'10-5'11), average body, black hair and kinda tan. I had only seen him shirtless once, and was thoroughly turned on. I especially loved how dark his nipples were. My only surprise was that he wasn't so hairy, just at the pits. Very cute face, hot body, I was turned on. We got along really well, and I recently came out to him as being bisexual. He's more than understanding, but in his words "I get it, I'm just straight." Well anyway, before he moved in, he had been hanging out at my apartment a lot this past weekend because we had a few days off. On one night, I was the only one in my apartment (my roommates were out for the holiday) and so was he. We decided that I'd be nice if we just chilled all night and he slept over here. After all, he was to move in in a few days time. So that's what happened. He came over and we started to talk. Since we're both really open people we started talking about our past, and when we started jerking off and all of the sexual experiences that have happened in our lives. I was hard, but I couldn't do anything about it cuz he was right there, and I knew he wouldn't join in. Some time went by and some other guy came over and was like hey, wanna go to the beach, so we went. We walked around the beach, got some food and had a nice outing. We got back around midnight and both wanted to continue our conversation. We're happy because we've found each other to have deep conversations and feel that no one else on the program could hold a conversation at that level together. We resumed our chat about penises, cum, jerking off and more and finally the topic turned to porn, so I was like "hey, let's watch some." Now, truth be told, I only like to watch gay porn. I'll occasionally watch straight porn, but I'd much rather get off to guys naked and having fun to say the least. Since I couldn't pick straight porn to watch I told him to put on what he likes and I'll be okay. We watched for a while, played some music for a while, and then around 3AM the following happened: Me: Oh my gosh, it's three in the morning Chris: That's the best time to jerk off! Me: So let's do it! Chris: Yeah, I haven't jacked off in a few days and I'm feeling pretty horny! I'll go to the bathroom! (The lights were already off because it was so late) Me: Dude, just do it here, on the couch. It's already dark, and you're already here! Chris: You sure? I don't wanna get cum on your couch. Me: Thats why you clean up if you make a mess Chris: True Chris sits down on the other couch that I wasn't sitting on, and pulled up his porn. He then put one knee up so I couldn't see his cock from where I was sitting. I was extremely aroused at how quickly he just stripped Me: Wait, can I come watch with you? Chris: I guess so I go over and sit down, my shorts still on. Rubbing my bulge because I could see his very erect cock, I noticed something. He is extremely hairy down there. I didn't pin him as the hairy type, and I personally love pubes and body hair on guys, so naturally I got even harder. Chris: this girl is so hot (In relation to the porn lol) Me: Yeah I know. A minute or two go by with Chris stroking his big, hairy cock and me rubbing my bulge Me: Alright, me too. I pull my pants down now too so we're thigh to thigh, naked from the waist below. Both jerking our very erect, both cut by the way, cocks. He had mentioned before that he had never really done anything with a guy before, so I could sense some uncomfortableness.We continue to jerk off until he says "Dude, I can't cum with you right next to me." So I move back over to the other couch and somehow managed to watch the rest of his jerk of session without him noticing. Thoughts? He seemed a little bit uncomfortable doing it, but still did. Is it worth trying to get him to do again?
