99

When a woman is performing a Mister Whippy from the anus (squeezing cum out onto her partner's face in a circular motion) and there is an accidental follow through planting a bit of brown on top.

I thought I agreed to only let my girlfriend to do a Mister Whippy from her arse for her birthday but one little fart later and I had a 99 on my face!
