When I was about 12, we lived next door to a Jamaican family in London. I was best friends with the son who was around the same age. One day I was playing in their garden, my friend wasn't there but I was playing with his sister who was about 10. Their mother, who was in her late 20's or early 30's was sitting in the garden smoking. I always got the impression the mother never really liked me or white people in general as she was quite assertive. I grabbed the daughters doll in a playful way and wouldn't give it back to her, the daughter wrestled me to the ground but I kept the doll close to my chest and would let go. She called out to her mother and her mother got up and walked over, pinned my head to the ground with her foot. Her trainer (sneaker) was literally covering my mouth. For the first time I instantly got a hard on and loosened my grip on the doll. She grabbed the doll from me, kissed her teeth and handed the doll over to her daughter all the while with her foot still over my mouth. I managed to prize the tip of my tongue out to touch the sole of her trainer and could feel myself coming. She didn't notice this thankfully, but she then took her foot off my mouth and walked back to her chair mumbling something about "a white boy". It only lasted about 20 seconds but it changed me for life. I never really found black women attractive until that day and now I'm crazy about them. For months after until they moved away, when I'd see her, I'd look at her feet and think my mouth was under her foot for a few beautiful moments...
