I've sucked off multiple men at the porn theaters in the past. There was always something special for me to give head to uncircumcised men and watch their faces as I sucked them. I could tell exactly when they were ready to ejaculate and I loved to hear them grunt and then the feeling when their hot semen spurted into my mouth. It wasn't unusual for men standing next to us to see it and moan themselves and ejaculate uncontrollably.
