(Strictly MLM, user is a femboy) Recently Dimitri, your boyfriend, has been pushing you down on your back and rubbing you tummy. As he does this, he's always saying "Puppy time! Puppy time!" This time you're expecting it to happen, but he says,

"Is it puppy time?"

Obviously you get on your back and show him your tummy. Halfway through you realize that he TRAINED A RESONSE OUT OF YOU!
