Sex Experiments

I went to school with a boy named Jake he was very smart. He loved science more then anything. I also liked science and biology. One day Jake received a microscope for his birthday after school he said he wanted me to come to his house for a really cool experiment. We were in his basement lab, and Jake said have you ever seen real live sperm? I said what do you mean? Live sperm like we seen in that film in biology class. Well I was kind of shocked,and curious at the same time. I asked how could we do that. Jake said if we use my sperm we could see it with my new microscope. Do you want to try? I guess so, I wasn't sure what he meant but I wanted to see what he had in mind. Jake unzipped his pants then pulled them to the floor and for the first time I saw a penis, other then the black and white drawing in health class this is my first inkling of a what a penis was. I never thought much about sex (I really led a protected life) Jake's penis was not hanging down like the book drawings It was hard and standing up. Go ahead he said to me. Go ahead and do what I asked. Masturbate me to draw out the sperm. I heard that term at school but really didn't know what it meant. I don't know what you mean was all I could say. Take your hand and jerk me off. I don't understand all the while I could not take my eyes from his penis. Let me show you Jake wrapped his hand around his thing and started to pump it. Like this he said. He took my hand and guided to his thing and showed me how it was hard and hot yet soft. This was the most exciting thing I ever did. After about 2 minutes Jake started to moan and shake he yelled DON'T STOP GO FASTER. I pumped it a few more times and he spurted this white stuff all over my skirt. Jake was out of breath but he had a happy glazed look on his face. After he recovered he took some of the sperm put it on a glass slide and put it under the microscope. Look at this he moved aside and looked in the eyepiece all these squiggly things were moving around. These things came out of him. Cool huh? You better take that dress off so we can wash off the cum. I pulled the dress over my head leaving me only in my panties and bra. Wow you have a great body said Jake. I suddenly realized I was wet between my legs, I felt really shy. Jake took my dress to the basement laundry sink and rubbed the stains with a wet cloth. His pants were now completely off I looked at his penis which was now softer. Jake walked back to me his penis bouncing. I was getting wetter. Want to see something else? He said as he reached into a draw. He pulled out a foil pack and said this is a condom it goes on my dick to keep girls from getting pregnant. Here put it on me. He opened the pack with his teeth and handed it to me. As soon as I started to put it on him his penis grew back to a very hard condition. Roll it on like this as he showed me how while I was doing it he reached between my legs and started to rub my pussy I was so hot at this point I thought I'd faint. Jake very quickly pulled down my panties and rubbed my pussy. I was in heaven I was dripping wet this never happened to me before. I never got sexually excited. Next thing I know I had an orgasm. This was my first. I sunk to my knees spasming and there was Jake's DICK right in my face. The condom seemed to have some of the sperm in it already. Jake asked me jerk him off again. I was happy to as I pumped him he sunk to the floor and started to play with my pussy again. It only took a minute before we both were having another orgasm. This time all the sperm was caught by the condom. After a short recovery Jake slid a finger into me and I came again. Then he asked me to put his dick in my mouth so he could see how sensitive it was through the condom. I did this for a few seconds. He said it was wonderful. We then masturbated each other again without talking at all. This became a regular after school event. He taught me all the sexy words cock, dick, pussy, handjobs, blowjobs etc: I'll never forget Jake
