The length was approximately three inches and the girth was thin—maybe a little thicker than a finger. He was still masturbating it then, and asked me if it was small. I said that it was hard to tell without measurement, to which he responded that I should measure him. I took out a ruler that I had in my desk and held it against the top of his penis. I had to hold his organ between my thumb and forefinger as he let go of it when I took out the ruler. It was exactly three inches long from the base to the top of his glans. I said aloud, “Three inches,” and as I was holding the ruler to it with my right hand, my left hand holding it up, I felt it jerk and saw a drop of pre-cum come out of the tip. He blushed red as I took my hand off him and he put his hand back on it. He asked me then if I minded if he could finish. I said that this was fine but that we had better collect the sperm in a cup so that we could run some tests on it. I brought him the cup and held it over his glans as he masturbated. He asked me while he was masturbating whether the size was small. I told him that it was below average yet not so far below that it would be a detriment in his love life. He was on the boundary of a condition known as micropenis, but I did not want to alarm him now. He looked a little dejected when I told him that it was on the smaller side and asked me how big mine was. I told him that was irrelevant and a question that I could not answer. Within a few minutes he ejaculated, I collected the sample, and he got dressed and left the session.
