Wanking in public SeXStoRY

Always on the lookout for some sexy young cunt to show my cock to. Last summer was out on the bike and got a bit knackered as it was hot and decided to get the train for a few of stops. Went to a station in a country part of Wirral that was deserted apart from a hot girl dressed in mini skirt. high heels and crop top showing off some superb tits. I guess she was 17 or 18. Gave myself a discreet massage and walked past her with the bike and an erection tenting my shorts. Was deciding whether to risk a wank when the train pulled in. I had to go to the end carriage with the bike and she got on in the middle - but when I sat down she appeared and sat directly opposite me. I got bone hard again but had to hide it with my backpack as there was an old couple opposite her. She kept glancing over, crossing her long sexy legs. After a couple of stops she made to get off, glanced at me again.....I thought, fuck it, let's go and see. When I got the bike out at another quiet station there was no sign of her up and down the road but then I noticed her in a phone box in the station car park. I cycled in her direction and could see she was on the phone but she then made a wanking motion with her hand and mouthed 'wank it'.....needing no further invitation I pulled my shorts down and started tossing off a couple of yards away. As I masturbated urgently she opened the door and said she was on the phone to a friend telling her what was happening...it was so horny I moved next to the box and groaned, spraying cum over the door...she was squealing and giggling....then said her bf was onhis way to pick her up so I shook the dripping sperm from my cock and shot off!
