This happened in the 1960s, many years ago. My only sister was 5 years older than me. When she was a teenager, she could be moody and bossy at times. Needless to say, I would often try to avoid her. But one evening when my parents were away, we ended up watching TV together. At some point we were talking about school and she started to tease me about my lack of experience with the opposite sex. I was barely a teenager and hadn't dated, so all I could say was "no" to her questions.

Her teasing got more provocative, and when I admitted I had never seen or touched a girl's breasts, she leered at me and lifted her shirt and exposed her bra. She asked if I wanted to touch her boobs. I was feeling awkward and didn't know what to say. Before I could answer, she then dared me to show her my penis. I said okay,but only if she would show me her pussy. I pulled down my pants then quickly pulled them back up. So, my sister pulled down her pants. But she kept them down and then dared me to lick her down there. She told me all girls liked to be licked while they were still virgins. I had no idea if she was telling the truth or had ever been licked (this was the '60s when teen sex wasn't practiced widely).

I remember how she sat on the couch leaned back and opened her legs. I kneeled in front of her and then very slowly stuck out my tongue and began to lick her. I wasn't sure if I was doing it right. I did it lightly at first and was a little bothered by her thick pubic hairs, which were already wet. She urged me to get closer. I kind of licked all around, not really knowing what I was doing. Despite my lack of skill, she was incredibly wet. And then I must have started to lick her clitoris because very quickly she started to sigh and whimper when I ran my tongue over what felt like a little bump. I wasn't expecting that. The more I licked her there, the more she whimpered. I could feel my face getting wetter and wetter as I licked her more eagerly. The sound of her voice, so unusually soft and full of those sexy sighs, really turned me on. After several minutes, she began to buck. I felt her hands grab my head, trying to hold me firm and steady against her sopping pussy. Suddenly, she gasped and I felt a spasm shoot through her body. Her legs shook and then she clamped them around my head, squeezing me hard.

When I pulled away and looked at her, my sister's face was deep red and she was breathing hard. Then she looked at me and quickly pulled up her pants and left the room. My dick was as hard as a rock, my head was spinning and I was quite out of breath.

After this experience, my sister would seek me out regularly when my parents weren't home. If my parents were home, she would have me sneak into her room after they had gone to bed. On several occasions, she pulled me into her closet when she needed some licking during the day. I never touched her in any other way and she never touched me. To be honest, I became obsessed with her licking her pussy and thought this was what sex was all about. She would get on the couch or her bed, pull down her pants and let me lick her. I got to be good at it and learned how to suck on her clit and pussy lips, as well as to push my tongue deep into her cleft.

I really liked how she would transform from a bratty teenager into a whimpering girl when I licked her, so I would do it more and more, sometimes for many, many minutes, making her cum several times before she would finally say, "enough" and push me away. On good days, I would count at least a half-dozen orgasms.

Later, I learned there was more to sex than licking, but by then it had become a powerful fetish for me and still is.
