A lot like a creampie. The tip of a can of whipped cream is inserted into a vagina and whipped cream is sprayed into the vagina. The women's partner then eats out the whipped cream.
Me and Michelle did our first whipped creampie together yesterday. We're both hipsters and creampies were getting too mainstream...
After the creampie is finished, the guy sucks his cum out of the vagina and gargles it until the right consistency. Then when ready, spits it back at the vagina.
