Alaskan Brown Flower
After a prolonged session of anal sex, the head of the penis is caked with feces. Upon withdrawal the recipient is presented with the penis as the caked-on-poo separates away like petals from a brown flower.
After taking Sally to a mexican restaurant for all you can eat bean burritos and margaritas, and an all night anal session while she was passed out, I capped the evening by presenting her a nice Alaskan brown flower.
