Hot Cross Bunning 

'Hot Cross Bunning' is a sex act in which two gentlemen simultaneously ejaculate across a lady at perpendicular angles (an X shape).

The aim is to make the lady resemble the traditional Christian Easter snack, the Hot Cross Bun. Aesthetically this works best across the buttocks.
A subsequent sprinkling of raisins or currants is optional but encouraged.

We celebrated the end of Lent with a spot of Hot Cross Bunning
