Jacking off for my mediator (with Mercedes Carrera)

You are in an odd predicament because of a clause in your prenuptial agreement. Miss Mercedes is your mediator and she has to help prove that you can keep an erection long enough to impregnate your wife, about five minutes. You will have to stay hard with Miss Mercedes for five full minutes, so get out your dick and start stroking yourself. Miss Mercedes brings out her fat titties as inspiration. Quickly she notes your dick leaking precum and she wonders if you can make it for the allotted time. Your mediator spreads her legs and you see that she is not wearing panties. Maybe your wife was accurate in saying you are a premature ejaculator, but you are here to prove her wrong. Even when Miss Mercedes shows you her round ass, you try to maintain control of your dick. When Miss Mercedes coaxes a load of cum out of you with a 90 seconds left on the clock, you realize your fate is sealed.
