Kyle and I had to comeback for another visit at the clinic where Dr. Topnbottom wished to run some more tests. The two of us met up in the waiting apartment of the clinic where one of the nurses took us back to an exam room. When Dr. Topnbottom came in he said that he has been comparing both Kyle and I with one another and we're both very similar when it came to bod type, ejaculation, and nut-juice count. The tests that he wished to run that day was that one of us would have his prostate vibrated and the other would not. Dr. Topnbottom said that he was going to have me activity like his assistant, and the very first thing that he was going to want me to do was help unwrap Kyle to give him fellatio. Kyle dropped his cut-offs to the floor and hopped back up on the table looking at me. The Doc chimed in about the lingerie needing to come off. That was when the directives commenced to come in about what I needed to do.
