- The Perfect Cum Shot is when a girl gets on her knees and spreads her asshole open. As she begs for you to cum in her ass, you give her a short squirt of cum and hold it as you tell the slut to get on her knees..as she jumps to her knees and begs for more opening her mouth - you release your huge load all over her face. That is the perfect cum shot. She feels like a total slut and you feel a sense of relief and humor. This cum shot can be seen live anytime by Lexi Rains and Jamie Stone of PornAddiction.
