Porn Party

When I was in secondary school, I would sometimes go over to a friend's house, JM, to watch some anime after school. And one particular day, I was there with another of our friends, ZY. Both of them were off in a corner discussing a manga and I was in front of JM's computer looking through the lists of anime he has, trying to find something worth watching. As I was clicking from folder to folder, I stumbled upon one that had a few Japanese titles which I didn't understand and which I assumed were anime episodes. So I was scrolling down looking for a title that sounds interesting until I saw the one that had the only English title called "cruelty party". It sounded like porn so like most teenage boys, I wanted to tease my friend for having a porn video. Me: Hey what's cruelty party? Is it S&M porn? Haha! JM: Eh it's not S&M la! ZY: But you admit it's porn la! JM: Why? You never watch meh? Me: If it's not S&M why is it called cruelty party? What is it about? ZY: Just watch it and see! So we gathered around the computer and I clicked on the video. It was a gangbang Japanese porn about forty-five minutes long. I was sitting on the swivel chair and my friends were standing behind me leaning on the back of the chair. I was getting quite hard which I'm sure was showing through my school pants and I had no way to cover. JM: So how? It's nice right? Makes you horny? If you all want, you can use the toilet. Let me go first. So off he went leaving me and ZY in his room watching porn. I debate whether or not to fondle my dick through my pants but I didn't think ZY would be comfortable with that. So we watched until JM came back. JM came back and sat down on his bed and almost immediately ZY said he was going to the restroom. Of course I knew what they were doing in the toilet but I wanted to be sure. Me: Hey you went to mast? JM: Yah la. You can also if you want. I didn't know if he meant it was ok for me to jerk off in his room in front of him but I didn't want to risk offending him if I did. So I just gently fondled myself in full view of him. He didn't seem to mind and even came to watch the rest of the video. When the video ended, ZY still wasn't out of the bathroom yet so JM and I knocked on the bathroom door. JM: Eh PCC (dialect term for jerking off) take so long ar? ZY: Wait awhile la! (He shouted from inside. And we heard the toilet flushing and he came out) Me: Wow why take so long? Other people need to go also. ZY: Yah yah, you can go now la. I went in and there was no sign that either of them had been masturbating. But I closed the toilet lid, sat down and began stroking my hard dick. Only just now I was turned on not just by the video but also by the knowledge that someone else was jerking off nearby, and then what turned me on more was knowing that someone knows that I was jerking off. It didn't matter that they were friends and in fact may have made it even more kinky that they were. With that in mind, I cam quite quickly and shot over the floor. By the time I cleaned up and rejoined my friends, they were back to discussing manga and I went back to watching anime. Thinking back now, I'm not sure if I or my friends would have been comfortable masturbating together back then but nowadays when I do, I wonder if they're doing the same or imagine them masturbating which really turns me on.
