It was strangely erotic when you opened up your wet cock holes and showed each other the insides of your cum pipes - your (the righthand?) cock was like a chasm (and I loved your gaping hole in the video 'My Glans Cumming all Alone" from eight years ago). From about the midway point, when your buddy's cock oozed a big juicy dollop of pre-cum, it's like he was on a hair trigger, waiting for you to 'catch up'. And when that first fat jet of semen spurted from your cock it must have triggered him, as only seconds later the cum was pouring out of his🥵. It was beautiful to observe the harmony between you.
