The professor is at his Office, I know that he works in the holidays and I am getting wet thinking about him, so I visit him in the office. I want to test my new titfucking skills on him. I can't decide what top I will be wearing for that. I choose 3 of my hottest tops and I go to the office. I explain to him that I want to train my tittyfucking skills in the holidays only for him, he is my lucky test subject. At first he's shy, but he almost loose his load while thinking about me tittyfucking him. I convince him and try the first outfit and I make him hot, then I tittyfuck him. He is sitting in his chair, I am between his legs and I let the top on while tittyfucking him. I'm going to edge him until the end. After some time I change to the 2nd outfit and tittyfuck him again. Then to the 3rd top and I suck him a little bit too. On the 3rd top, my eye contact and my dirty talk is so hot, that he shoots his load while I tf him with my top still on. The test and the training was a succes
