I hung out with my brother today and his best friend. We were at his house playing video games, eating, watching sports, etc. I have always been attracted to my brother's friend, we'll call him "Caleb" but have never took action to this. Today while getting something from the fridge Caleb came up behind me with his crotch in my ass, reached over me and got a water from the fridge. I didn't pay to much attention to it and moved on. Later on today he would grab or adjust his dick anytime I looked over at him and one time winked. My brother went out to grab us some Chinese food and Caleb satyed at my brothers house with me. I went to take a piss and when I'm going he comes in and says don't mind me I just gotta take a piss too and whips his out. I can't help getting a semi from being attracted to him and he notices this and says, "Like what you see, why don't you grab it?" I just laughed and zipped my junk back up. The question is should I go after my brothers best friend? I'm seeing him tomorrow.
