FunSizeBoys STORY: Grant CHAPTER 3: Anal Ultrasound

Once I got Grant striped down and on the exam table, I turned the machine on. I started out with one finger and a little anatomy lesson. He didn't know what his prostate was, but that's not uncommon among boys his age. I can say, he knows what it is now. One of the many things that I like about my ultrasound is that it keeps a boy entertained and I can finger fuck them as long as I want. Usually, they only want to take so much before they are revved up and want something bigger in their hole. Grant was fascinated watching my fingers massage his prostate. He also learned that fingering can be about more than just getting his hole relaxed enough for a cock to go in. I started with one finger, but I quickly moved up to three. I think my prostate massage had him harder than he had ever been in his life. Of course, the ultrasound is good for that, too. I'm not just feeling around. I can see exactly what to aim for. I just love feeling the soft hot depths of a boy's body. His legs spread open for me. His tight sphincter gripping the base of my fingers. When we start to actually fuck, the sensations quickly get overwhelming for both of us, but there is a clear headed vulnerability for a boy when he is lying there taking my fingers.
