I was 18. My sister was 19. She came home from college for Thanksgiving. She said all the girls at college were discussing sexual experiences. Being a virgin, she was embarrased because she had nothing to tell. She said that we were both virgins and both wanted to see what it was like so if we did it together, we wouldn’t have to worry about STD’s, just make sure i didn’t get her pregnant. I told her we shouldn’t do it because she was my sister. But then she stripped in front of me. That was the first woman I had ever seen naked. When she did that, i knew i couldn’t resist. She got Mom’s contraceptive jelly but although the tube said you could use it without a diaphragm, it did not tell the dosage. She told me to call the drug store and find out how to use it while she took a shower to shave her legs and underarms for me. I called and to my horror a female pharmacist answered. But i was so horny, i thought, what the hell, i will ask her. She said we shouldn’t do it because we were siblings. I told her i told my sister that but when she striped i knew i couldn’t resist. I told her if she didn’t give me the info, we were going to do it anyway, and if we had a baby, it would be her fault. Reluctantly, she told me my sister should insert one applicator full in her vagina before we started. And if we repeated intercourse to put in another. When sis finished shaving, we put in the jelly, i got on top of her and slid it in. I am small, so it went in with little problem. I lasted about one minute but we put in some more jelly and i soon got another hard on. I lasted a good ten minutes the second time and she had an orgasm. We both enjoyed it, but said we should not do it anymore. Needless to say, we kept doing it until we found gf and bf to do it with. I guess we kept it up for about a year. But no girl I have been with since is as good as she was.
