This is a custom clip: "I’m thinking something along the lines of a JOI stamina test. If I cum before the allotted time (set by you), then as a punishment I must hold the cum in my mouth for the remainder of the test. I’m quite certain you can get me to cum early, then you make me swirl and savor my cum for at least a couple minutes before making me swallow my load for you." To make this even more difficult I decided to make the timer ambiguous, not setting a specific amount of time. This makes it even more difficult to hold out. It's doubtful that any man can resist my teasing.
