Before I get into the actual story some background is needed. I’ve (heterosexual male) been friends with my gaybff (J) for a couple years. One day a couple years ago I was feeling sexually curious so I asked him if he wanted to come over for some experimentation and fun. He obliged, and I gave him a BJ and fucked his ass. I wanted to switch it around but it didn’t work out, due to a combination of my ass being too tight and his dick too big. No matter, still had fun. I needed straight porn to get hard and cum and it was definitely an interesting experience that satiated my curiosity, but nothing came of it. We still hang out as normal bros with zero sexual or romantic tension.
