Its our first annual college sperm drive and we are paying college students to donate there sperm and we are paying them $100 for there donation. The first patient to arrive was Mikey that has been to our clinic before. Mikey if you remember has been with Dr. James and Dr. PhingerPhuk but this is his first time with me. He came into the clinic with a flyer advertising the sperm donation and he wanted to earn the $100. Since Mike is broke, and a struggling student, he can always use the extra $100 bucks. I had him sit on the exam table and I did a quick check of his vital signs. He wasn't here for a complete exam but I just wanted to make sure that he was in good health. I guess Mike was surprised and thought he would just be in a private room and jerk off and give him his sperm sample but I kept on examining him. I had him drop his pants and I examined his genitals feeling the shaft of his hugh cock. As I was feeling it, his cock started growing and getting hard in my hands. This guys cock was huge and for such a skinny kid, he had a wonderful hard full cock. I think he didn't realize that giving a sperm sample wasn't going to be that easy. Lets face it, if our clinic was going to give $100 for sperm sample, its not going to be just a simple jerk off and leave. I connected Mike to the electrostimulation device and place the bands on the base of his cock and on top of his glands penis. Having the bands in place, I then started the electro out in small waves of current flowing through his cock. I then inserted the electro butt-plug into his tight ass. Mike really didn't care to have something placed in his anus, but again, I wanted to make sure we stimulate all parts of his genitals to maximize his cum load. I played with the electro machine and let the device stimulate him for a while. Mike was handling the pulsation like a real man. Having current pulsing in and out of his cock and then pulsation of his prostrate, Mike was throbbing really hard. I figured give him a hand. I first examined his cock and felt how hard he was and his nutsac was tight and ready to blow out some hot cum. I stoked his cock and as he got closer to climax, I placed the collection tin and collected the spurts of cum shooting out of his cock.
