First you get a gay actor that isn't turned on by women. Then you get him to cum a few minutes before you start filming. Then you give him Viagra to keep him hard. Sooner or later he'll cum, but it will take awhile.
Unbelievably hot! How does he last without blowing a load? With 3 girls around him with one licking his nipples while the others suck cock- I would cum in seconds
