Happened to me and a mate of mine! When we were kids we used to knock around with a girl and her friend and a few others, played various games in our adolescence, truth or dare etc, probably around 12 or 13. This one girl though had started getting tits, and I mean big tits for her age...me and my best mate used to talk about how amazing it'd be to see her naked etc etc, typical 12 year old fantasies - had many a hand shandy thinking about her at the time.
Anyway, 20 years later (!!) and ive just discovered WGs and started browsing through AW in the local area and spot this BBW with huge tits, just what I'm after...looking through all her pics I realise it's her!! Madness! Took a while to recognise her but she had quite distinctive curly hair and a gap on her teeth which confirmed beyond doubt, plus it was obvious all those years ago she'd have enormous tits as an adult!
So I thought fuck it, she'd been my fantasy fuck at 12, I'm going to fuck her for real...turned up, she didn't recognise me at all, which is good because she lived extraordinarly local to me. She had done porn, TV X etc, and man it was one of the best fucks id ever had, came all over those tits just like I'd imagine decades before!
Told my mate about it, and he remembered her too...won't go into details but a 3s up was arranged and it was fucking awesome. She'd moved down to the coast by then so we came clean with who we were, she got even more into it when she knew.
Surreal.
