Swatch to time or countdown, but with a story. So the story is you are a teacher and he is a student, he enters the room and come to you because today is his final exam. You will tell him exam is simple, you will give him handjob and blowjob and he has to cum as fast as he can. You will use your swatch to time him, and for every 10 second pass, his point for exam will -1, initial point is 100. So if he want to pass, he will need to cum in 10 minutes. Then you will use the stopwatch on your swatch to time him while give him handjob and blowjob, and try to make him cum when time is almost up. During the process you will keep looking at your swatch to tell him how much time has past. And also tease him or threat him to cum in time.
