She was five and lived next door.

She'd come over to play on our trampoline in her bathers. I lured her into my cubby house and showed her the copy of "Where Do Babies Come From" that my parents had got me to explain the bulging stomach my mother was sporting. We decided to give it a go ourselves.

Can't say it was a rip-roaring success, but on the plus side I built up some sort of peadophillia immunity because I haven't had it off with any five year old girls since.

Embarrassing Postscript:
Around ten years later, living in a different city, down the shops with my Mum, who stops to chat with some lady and her daughter. "Oh you remember Wotshername don't you? They used to live next door to us back in OldTown, and Wotshername used to come over and play with you on the trampoline."
