A guy squats, while his girl sits beneath him with an ice cream
cone. The girl then proceeds to pull on the guy's erect
unit as if she were pulling the lever on a soft serve ice cream dispenser. Once the "lever" is pulled, the guy releases his soft serve-like doodoo into her ice cream
cone. She then can get "whipped cream" to
top her soft serve by jacking off/blowing the guy. At this point, it's up to the guy to decide whether she eats it or not, but she at least has to lick it.
