On Melissa's bush

You pull out of the model, ensuring that her pussy is well gaped for the class and walk over to Melissa. She senses your intent and pulls down her jeans and panties, exposing her vagina. The rest of the class furiously rubs their pussies, some having yanked their pants to their ankles .

You stroke yourself until a thick load jumps from the tip of your dick, essentially frosting her muff as if it were a pastry.
