Dirty Hershey
When you get your asshole spread out someone blows in it.
As soon as I finished she opened my ass and gave me a Dirty Hershey.
Dirty Hershey Kiss
When a female didn't wipe too well, then someone fucks her doggy style. As the ass is bouncin, the resulting shit stain on the male pelvis is a dirty Hershey kiss.
"Man, it was going great, till she got on all fours and gave me a dirty Hershey kiss"
