Guy A is kind of a gloomy kid who likes guy B. Guy B is this one kind person. One day, Guy B is asked to do some errands. Guy A followed Guy B and then knows that Guy B isn't actually the type of guy he thought he is. Guy B then realises that Guy A is there. He asked Guy A to not tell anyone. Guy A got stuttered and made Guy B thinks that he would like a blowjob.
