Clubbing in the metropolis isn't so bad you tell your friends when they keep asking why you do it, ‘ Why do I do it ?'you ask yourself for the tenth metre as you and you sister remain firm on the crowded platform waiting for the tube habitation. Both dressed in annulus that are almost too unretentive for decency and fast big top, your sister has always complained that you don't wear a bra ever, your breasts firm enceinte and almost falling out of the lower cut neck occupation. 11pm and you can't believe how many people are still travelling, you see her jump and quickly look bout, ‘ I've just been goosed !'she exclaims, pervert she says to the crowd in general as a number of men look on leering.

Pushing on to the future subway that comes in you're stuck in the middle of the carriage, you sister in front of you squashed close. You feel dead body behind you pushing against you as More hoi polloi push on to the train. As the doors close and the caravan lurches you feel a hand grab you arse, tensing you feel it let go and you think it must have been an chance event. Leaning in to you your sister attempt to lecture as the trip-up continues. Again the train lurch and the bridge player catch you again, this fourth dimension when the power train moves it stays where it is !

You tense again but don't say or do anything, the handwriting gives you bottom a little hug and when zippo happens it moves down to the hem of your doll, noticing you've gone quiet your babe asks ‘ what's wrong ?'shaking your heading you mouth a headache. Feeling the hand slip under your skirt on to you almost air ass you shiver slightly, again it squeezes and again when you don't complain it moves to your tail end crack, a fingerbreadth follows it down, reaching the upside of your second joint it stops. The train lurch for a tertiary time and the handwriting disappears, this fourth dimension you have to mistreat forward to stop over yourself falling over, as the train motion off you stand nervously with your legs slightly apart. You feel a petty guilty as you realise that you're hoping the hand will return.

Nothing happens and you start to retrieve nothing will, then you tremble again as the hand motion straight under your skirt and on to your arse, moving straight down to where it was, the paw hesitates for a second when it finds you legs slightly open, then moving again it slips between rubbing slightly but with the packed carriage it can't go where it wants and pulls away. A sudden letdown suitcase you as feel it move then a trunk pushes harder against you and you feel the hand, still under your doll, move slowly round your outer thigh and on to the front of your leg, this time the hand doesn't plosive but moves straight to your shaven mound, two digit slip between your legs and your priming up against the eubstance behind you. You start to flush as the fingers expertly stroke across your pussy mound teasing you.

Feeling yourself getting damp you move almost without meaning too, opening your stage wider you invite the finger's breadth to do as they will, accepting both fingerbreadth slip inside your now wet pussy lip and start to tease you rubbing you tingling pussy harder, finding you clit they slip either face of it as they rub, rolling its hardening nub between them as you're almost panting now as you feel yourself starting to shake as you realise you're going to orgasm right there in the packed carriage and right in forepart of your sis too !

Trying to ascertain yourself you look at her for the first time and realise she hasn't said anything for years, seeing her looking down with her mouth wide candid you know she can see what's happening to you, she suddenly looks up at you and you flush furiously as your orgasm hits, you grab the pole between the two of you as wave after wave of pleasure throbbing through your body making you shake off harder with ever rub of the stranger fingers, the train lurch again as it pulls into a station and the helping hand disappears as people get on and off passed you as you still shake.

The geartrain pulls away and now you find enough way to release rhythm, disappointment flows through you as you realise one of the people who got off the train was your mystery hand ! Trembling now you turn back to your sister who has a questioning look in her eyes, without her asking you lean in and whisper ‘ no I don't know who it was'as she gasps you feel her deal touch the nominal head of your skirt and realise that your juices have soaked it where the helping hand had been. Grinning with embarrassment you look at your sis as the train pulling in to your place. ‘ Let's get the car'you say to block off her speaking.

In the car park you get in the car and she turns to you, ‘ why did you let it happen'she questions. ineffectual to answer her you just shrug and say ‘ I couldn't supporter myself once it started'she sigh and admits she wishes she had the courage to let something like that happen to her, without stopping to cogitate you reach across to her, ‘ what are you doing ?'she gasps. Placing a digit on her rim you quiet her, your other hand slipping her skirt up exposing her white lacy thong, you stroke across it and she jumps ‘ don't, this is wrong'she objects. Ignoring her you stroke again this time a footling harder and further down between her wooden leg, gasping again she opens them a little wider without being asked. You stroke again and this time you slip the thong across baring her trimmed pussy, as you look down at it you find your own pussy throb, touching the trimmed fuzz you again stroke her pussy. Feeling it deaden as you do you slip a finger's breadth inside and rub up and down coating it in her juices as you listen to her pant and moan low.

fillet for a second base you look at her as she opens her branch wider ‘ please don't stop'she almost begs you, seeming to forget who you are. Again you start to ride her pussy rubbing the duration of your finger up and down, finding her clit you tease it running you finger tip round of golf and over it concentrating all your movements on her button now you rub operose as she starts to pant louder, moaning like nothing you've heard before. Suddenly she clamps her second joint together trapping your hired hand between them and holding your fingers against her now rock heavy throbbing clitoris as her orgasm rips through her body she almost arch herself up and out of the seat, crying out with the pleasure.

Shaking as her orgasm subsides your baby releases your hand and looks at you shocked, ‘ I can't believe I let you do that to me'she rustle embarrassedly. ‘ it's our footling secret sis'you reply as you start the car and rend away your fingers still coated in her juice, glancing at her you hear her gasp again as you say ‘ maybe you'd like to try something more with me some sentence ?'.
