My step-brother will never know (Part 2)

To quickly re-cap: I have a hot step-brother who as far as I've told you has a pretty big when soft cock. He's completely straight, and I am not. If you want to read part one, check out my profile. OK, so where does Chapter 2 start? Once my step-brother and I started living together, I began to notice how often he would hide his boners, which were as frequent as he breathes. Now, I'd like to tell you the part of the story where I get more and more curious, and the things I do to get off. Alright, so to begin, we naturally have a good relationship as far as step-siblings go. We talk about girls (I am bisexual, so I can relate for some of the conversation) and other things. Naturally, among the topics of discussion is masturbation. How often we do it, where we do it and so on. We talk about what porn we watch (I of course didn't tell him that I strictly watch gay porn, but nevertheless) we would talk about these things. I soon learned that his routine consists of jerking off right before he showered. I knew when he would be jerking off, so when he went into the bathroom for his shower, I would very stealthily lay on the floor outside and look under the door. I couldn't see his actual dick, but I could see the shadow, I could hear him, and I could see up to his ankles. I would watch his toes curl just as he's about to cum and then would go back upstairs to jerk off. This would go on for a while, and after his shower, if there weren't many people in the house (as there often weren't) he would walk around for a while in his boxer briefs. I guess he would play with his dick in the shower, because he was almost always semi-erect. I am good at sneaking pictures, so I have pictures of him in his underwear with a half boner. I still jerk off to them sometimes. Around the same time all of this started to happen, we would have some interesting nights. Since we are friends as it is, he would frequently ask if I wanted to hang out in our basement and sleep there for the night. I always said yes. We would go downstairs, each on a couch. We'd watch movies and talk until the early morning hours. The couches were in an "L" shape and we would sleep so that both of our heads were at the corner of the L. This meant I could easily look at him without him noticing. There was one time where we starting talking about porn. I had been getting the idea that maybe he would be open to jerking off, so I suggested we watch porn. He of course said yes, and we put on straight porn. I, on the other hand, was getting turned on by the thought of possibly getting to jerk my step-brother off. All I want, truthfully, is to suck his cock. I want my mouth to be on his thick hairy cock, seeing how much pleasure I'm causing him. I want to make him cum. With those thoughts running through my head, my cock was rock hard before the porn stars had even gotten naked in the movie. He noticed, because I wasn't really trying hard to hide it and said "Dude, you're horny all ready?" I said: "Yeah sorry. Wait, you aren't getting horny?" He said no. Meanwhile, he was stretching and I could see the tip of his hard dick, he had waist-banded it. I asked if he wanted to jerk off, he quickly declined and nothing much happened that night. I have a few other stories from the basement, and of course the grand finale. Stay tuned for part 3, and possibly a part 4. Thanks for reading!
