My sister taught me a lot about life and sex, so it shouldn't be a surprise that she taught me about anal sex.

One night we were having a bath together (I was about 10 or 11 I guess) and she told me that one of her friends lost her anal virginity. We were pretty grossed out - get real, you poop from there so it was just not on! Being very curious, we obviously wondered about it, and almost simultaneously our hinds slipped to our assholes. I was quite apprehensive, but not my sister. Within a minute or two I could see on her face that she was loving every second of whatever she was doing under the water. By then I just gave my ass a few tentative little prods and brushed it with my middle finger.

She then said turn around and stand on your hands and knees. One thing I learnt early in my life is that when she told you to do something it is generally better to do it, so I obliged. She pulled my cheeks apart and started licking up and down my crack. My first instinct was to pull away, and my asshole involuntarily tightened, but that didn't stop her, and after a minute or so I could feel myself relax, and I started to enjoy the feeling, even though it was still weird.

When she started fingering my pussy while still teasing my ass with her tongue things changed, rapidly. I could feel my asshole relax and she teased it harder with the tip of her tongue. When my orgasm started she used her other hand and gently inserted the first digit of her index finger into my ass. I NEARLY TOOK OFF!!! It was AWESOME!

When I came down she asked "how was it?". I just replied: "Get on your hands and knees and I'll show you..."
