First, you jizz in a gatorade bottle for a month to save up a lot of old, smelly, crusty cum. Second, you fuck a girl from behind. When it’s time to cum, you pull out the bottle with your juice and pour it allllll over your partner’s back, making it like a cum waterfall (the “Niagara”). Third, when the partner turns around and yells “HOLY SHIT!” you bust in their eye (the “Surprise”).
Bukkake’s for amateurs; I pulled a Niagara Surprise on that bitch!
