Pinkie Pie and Cheese have been screwing each other for four months now, trying to concieve a child. Now, Pinkie's Pinkie sense is telling her that now is the time, but only if Cheese can cum in her again by midnight. The two race against the clock to get that final load shot into her before the end of the contest day.

Warnings: Sex between a mare and stallion, Impregnation, Weird Al stealing your waifu.

My final submission for Dirty Little Secret's Dirty Little Contest.
