For girls, that would be tasting things with your boobs. Think about it, wouldn't that be awesome? If you want to make a soda last, instead of drinking it, just stick your schlong in there for a minute to savor the flavor. Got a nice hot pie? Stick your wiener in that hot pie. Stick it in a cake. Stick it in a bowl of nachos. Stick it in a taco. Rub it on a waffle. The possibilities are endless!
