Secretly jerking off while playing video games

My friend and I were playing a game over xbox live, he was setting up something in the game that was going to take a few mins, sometimes when he does that I watch porn on my phone to pass the time and give myself a few tugs while I'm waiting...this time however it was taking him a little longer than usual, so I just keep pumping away and I knew if I didn't stop myself I was going to cum, well, it was feeling so good that I didn't stop, I tried to be as quiet as possible as I came and I think I got away with it too! lol Damn, that felt good!
