I am not sure but I suspect that I have fathered more babies than any other 17 year old male on earth. To make matters worse I am still a virgin. No, No I have not been on any sperm donation program at least not officially, and certainly not any approved program. I am a mostly normal permanently horny 17 year old male, I go to school where I get good grades. I am so normal looking that I guess that explains why I am still a virgin. I just don’t stand out in the looks or body department to compete with the jocks and the cool guys. They never seem to be lacking female company or if the gossip is correct they get just about as much sex as they can handle. Me and my friends the average looking guys just don’t rate enough to pick up the girls. I am sure that if you looked up average in the encyclopaedia my picture would look out at you, but you may not even notice it then. Anyway enough of that teenage angst, how could I “Mister Average” have fathered thousands of babies yet still not have found my way to sampling the delights of a girl let alone a woman? It is an interesting tale that started out when I was 15. My parents own a cleaning business, so what you say. Well it is not just any cleaning business, they specialized in cleaning Medial Practices and Clinics. I had been after my dad to let me work for them to earn some money, as any teenager does. He had set a bunch of conditions that I had to meet, school grades, marks, attendance etc. Since I was well above those targets I found my self heading out at 6pm with him or mum most nights to clean and tidy my way to financial freedom, lets face it $10.00 allowance does not go far these days. Time passed buy and I got very good at doing what was needed and mum and dad never had a complaint about my work. It got so that they would drop me off at 6 in an area that had several of our customers in a single small medical services mall. This was connivent for them as they could drive to the other customers and I could push my cleaning trolley from door to door in the mall. I got to know the security guards real well in the mall and they would often chat with me between rounds. My customers were 2 oby/gyn practices, a Fertility clinic a Sperm Bank and several other specialities. Ah ha I am sure that I just saw a light bulb light up. Well it wasn’t a planned thin not at first. I would do my cleaning and hurry to finish as I had a lot of ground to cover, however as we all get better and better at our jobs as we get experienced I found that I was finishing with time to spare each night. Sometimes I had an hour to kill before mum or dad would pick me up. I sort of forgot to mention that to them as I found I was enjoying the quiet time by my self with little to do. It was during my cleaning of the sperm bank that I got diverted one night. I was cleaning out one of the rooms where males go to be alone to give there deposit when I glanced over in direction of the magazine rack. Normally the magazine racks were neat and tidy and I never touched them but this night the nurse must have forgotten and they were everywhere. Teenage curiosity got the better of me and I stopped to have a gander. After a careful examination of several glossy porn books I was as hard as a rock and needed to whack off. I suppose I was in the perfect place for it so I whipped it out and before I could even think about what I was doing I was blowing a seriously big load of jiz all over the coffee table in the room. God was that good!. As all teenagers I got the guilt’s and started looking around, to make sure no one had heard me. Doh! I thought the is nobody but me here. I then had a revelation that was to start me on a strange path. I have found the perfect place to wack off with no chance of mother walking in catching me and then embarrassing me for the rest of my life. My pattern of cleaning changed after that, I left the sperm bank till last and worked hard to finish all the other places first. I would then check out the racks of magazines in the rooms and get comfortable and enjoy my self while eliminating all those nasty excess hormones that seem to build up in my balls all day, and it was in a place that was designed for it. Amazingly this can get boring after a few months. One night in my post orgasmic lassitude I was thinking about how it was time to clean up my mess and move on. I was musing that it would be nice not to have to clean up my sperm each night when a thought came to me. Hummmm I am in a sperm bank what do they do with it? After finishing cleaning and closing down the place I was out at the nurses station when I spied of all things a copy of the training manual for new nurses at the bank. I not being too stupid read it from cover to cover going from room to room in the sperm bank learning all the processes involved. The next night found me whacking off as usual to some particularly stimulating images of two girls riding one guy. I came lots but this time it was into a sample jar. I was still hard so off I went again and left another load in the jar. I then proceeded to the sample storage room. Opening up one of the storage containers I found the number I was looking for took it out ran it under water till it was defrosted and then washed it down the sink carefully drying it and then loading my sample in its place. I had looked on the computer in the storage room first to find out which one had Caucasian samples in it. I figured that if mothers of other racial types started having half white babies that someone would figure out that something was fishy. Over the next three months I replaced all the sperm in storage with my own. I would have strange fantasies about what was happening to my luck sperm and then wish that it was me delivering it in person. I got into quite a routine with this till I got really curious to see if I had produced any results. I knew from the records on the sperm banks computers that the 2 ob/gyn practices and the fertility clinic were the main uses of the sperm bank with there use being 95% of the material. Having access to all 4 places I was able to track down what the results of my late night mischief. I found that the very first sample I had changed had been used and that the mother had got pregnant on the very first insemination. Oh God!, I am going to be a father, sort of, kind of. Being a very curious boy now I looked up records as to where I would find the mother to be. I went out jogging the next morning and went past the address given and was stoked to see a nick looking lady about 35 kiss her husband goodbye as he left the house. She turned and I got a look at the beautiful bulging shape of my first child. Over the next 6 months I watched the records and noted that 218 of my samples had been utilized. Not one of them failed to produce a pregnancy. However in the end only 150 babies were born. I have kept this up for several years now with my tally being 1004 babies. That‘s not bad in a city of 3.5 million people. I did have some really interesting outcomes from my perusing of the records of my samples. My mothers best friend, who I now kind of lusted after, had a beautiful little girl with brown hair and blue eyes after using one of my samples. Funnily the notes on her record say she never told her husband about having the AI done, he was sterile according the rest of the notes so none of their 4 children were his. Another one that had my jaw drop were two of my high school teachers. Both of these two were really something to look at and I have to admit that I had produced a few samples from fantasies involving them together or individually. I found out that according to the records they were living at the same address and had been inseminated at the same time on the same day. They had timed it so that they would have their babies during the summer break and one of them would stay at home to look after the two children. I was most devastated to learn that they were a dedicated lesbian couple, but on the upside I did get them pregnant, oh well. In the end I had regular contact with 8 of my babies and I am sure to see them grow over time. I have kept records where I could and I think I will get a kick out of recognising a name somewhere in the future and knowing that that is one of mine. I am now about to graduate school and go to university so my wholesale sperm donation days are about to come to an end. I kind of hope to be able to continue to donate sperm but this time in person.
