So you want to be a sperm donor? Very first you have to take your pants off and I will check your testicles. Then we have to do a sperm quality test. Its a very special and unusual test but trust me, we need it. Here I have 2 cups, one with very cold water and one with very warm water. Very first you will dip your ballsack into the cold water and you have to measure the time, how long you can keep them inwards. Right after that you have to dip them into the hot water to get the right consistency of your sperm. And then you have to stroke for the number of minutes you measured before. I will come in for the last 2 minutes because you need to jizz exactly on the last 2nd of your jacking and I have to make sure you make it on time. I will tease you, take all my clothes oh boy, I am sure you will make it and you will be a good and efficient sperm donor;......
