I was on holiday with a friend of mine:he was bragging about his fat rock hard cock, all the time. We bought a porn magazine, and got to our room to have a look. At the sight of all those chicks getting fucked, my cock began to rise, asking for freedom from my tight trousers. I caressed it, and i noticed my friend was doing the same. I told him: how can you keep it there? i feel my pants exploding. He turned red and smiled. I went on: don't be shy, if you want you can jerk, mate. Wanna bet i am bigger than you? Nope due, i am bigger, i bet, i have a very thick pole between my legs. Maybe you're right-i answered- but who knows. All of a sudden our cocks were out. My cock was half hard, and already way bigger than his. After a couple of wanks, i got fully hard and asked him: who's the big boy here? He was strained, i guess, he managed to babel: with that thing you should do the movies, it is incredibly thick. His looked about half of mine in lenght, and way thinner. We went on jerking at our magazine, and he was always telling me i was bigger than the guys featured there. I was excited at the sight of his ridiculous weenie besides my cock. He was humiliated instead, and never mentioned his big pole again.
