Keith had a really tight hole and it took me a while just to get my finger inside. Once inside I felt and massaged his prostate and to my amazement, Keith stayed hard. As I had my finger in his anus and massage and pressing his prostrate, I gently stroked his cock. There are time when guys blow there load at this point but I wanted to see how long will it take and let him enjoy this part of the exam. As his breathing got deeper and I continued stroking and massaging his prostrate, I decided to use the eros prostrate stimulator and then I continued to stroke his cock and examine his balls.
