OMG! Flatmate caught having a wank

When I was looking for my laptop again, I came into my flatmate's room. But what I saw there left me speechless - he was lying there with my laptop and having a wank. As if that wasn't enough, he was also watching my porn. But when I saw his big splendid boner, I felt completely different. How do you think I reacted, what did I do to him ?????
