Am I really thinking about sucking his cock?

Me and my best friend have always been close, during summertime in school we’d spend almost every day together hanging out talking about chicks, trying to get them to hangout, just doing what bros do. One summer we were together almost every day for a week, I was practically living with him in his room and his parents were always at work. While watching some tv and playing around on our phones he had showed me some nude pics he received from this chick he was talking to and it was really hot, he scrolled through his saved pictures and accidentally showed me his dick, however he quickly scrolled away. I couldn’t see much at first but I could tell it was a pretty nice cock and to my surprise I couldn’t stop thinking about it. We were both just chilling him his room relaxed all day and he was in nothing but his boxers, I couldn’t stop thinking about that picture. Later on he went to the kitchen to make some food and he left his phone, he was my best friend so I knew the passcode to get into it and in a moment of weakness I went into his phone to spy. I found more intimate pictures and videos of his cock and I was shocked, my heart started racing as I watching a video of him slapping his cock on his stomach (this thing had to of been 8.5 inches or more.) Pre cum was dripping from his tip in one video as he played with it and it made my mouth water, but why was I reacting this way? I never have wanted a man before but I couldn’t stop obsessing over my friend’s dick. Anyways later that evening we were still just hanging out, he was in his boxers when I asked him to once again show me the pictures of that chick, and he did only this time he proceeded to show me a sex tape they had made together, it was hot watching him rail her from behind as she moaned with pleasure, and I could tell he was into it as well by the bulge in his boxers. As we both watched the video play on his phone I made my move, I grabbed his dick through his boxers all of the sudden, and he didn’t even flinch. It was like he knew I would eventually cave and give into his dick. I pulled the long straight cock out of his boxers and began to stroke it and before I knew it my eyes were rolling in the back of my head as I sucked his dick in the dark.
