How Deep?

So how deep can I go, meaning how much dick can I take. A guy from an adult toy company did a video of me using one of their products, a nine inch thick dildo. He does an interview with me and then I masturbate for a bit before taking on his toy. Then I use the didldo in three different positions to see how much of the nine inches I can take. After each position, I take it out and he measures how much of it I took inside me. You will have to watch to see how much I can take. 30 minutes.
