skittle surprise
The act of inserting skittles into one's urethra so that when they ejaculate during oral their sexual partner "tastes the rainbow."
Jimmy eagerly inserted each color flavor of the tropical skittles pack (the tropical thunder variation) inside his dick hole as Elsa waited in the other room awaiting the surprise promised to her the entire 7hour flight to Hawaii. The door flung open from the bathroom into the master sweet, Jimmy's dick half mast and lumpy from the inside out Drizzling pinkish precum elsa takes his now hard yet still lumpy skittles filled cock into her mouth, the best tasting cock she'd ever had. Jimmy lasts a mear 2minutes before ejecting each and every last of the skittles into the back of Elsa's throat as Jimmy loudly moans "Skittle surprise"
