Sample Ninja Porn: "The funniest thing happened to me the other day. I went to Fatburger to get lunch. While I was there, I overheard a conversation in the next line over about how breathless, panting gasps accentuated the rhythm of their bodies, writhing together while intertwined in an animal embrace. Though I was intrigued, I decided that the #1 combo was too expensive; I ended up getting just the normal hamburger and a cup of water."
