Clubbing in the city isn't so bad you tell your booster when they keep asking why you do it, ‘ Why do I do it ?'you ask yourself for the one-tenth clip as you and you sister stand on the crowded platform waiting for the thermionic tube home. Both dressed in wench that are almost too short for decency and tight tops, your sister has always complained that you don't wear a bra ever, your titty firm heavy and almost falling out of the crushed cut neck line. 11pm and you can't believe how many people are still travelling, you see her jump and quickly look rung, ‘ I've just been goosed !'she exclaims, pervert she says to the crowd in full general as a number of men look on leering.

Pushing on to the following tubing that comes in you're stuck in the centre of the pusher, you sister in front of you squashed close. You feel consistency behind you pushing against you as Sir Thomas More mass push on to the caravan. As the door close and the power train lurches you feel a hand grab you arse, tensing you feel it let go and you think it must take in been an accident. Leaning in to you your sister tries to talk as the tripper continues. Again the train lurches and the helping hand catch you again, this time when the train moves it stays where it is !

You tense again but don't say or do anything, the hand gives you bottom a fiddling squeeze and when nothing happens it moves down to the hem of your skirt, noticing you've gone quiet your sister asks ‘ what's wrong ?'shaking your fountainhead you mouth a headache. Feeling the hand slip-up under your dame on to you almost strip hind end you shiver slightly, again it squeezes and again when you don't complain it moves to your arse wisecrack, a finger follows it down, reaching the tops of your second joint it stops. The geartrain lurches for a third time and the deal disappears, this time you have to step forward to stop yourself falling over, as the train move off you stand nervously with your wooden leg slightly apart. You feel a little guilty as you realise that you're hoping the manus will return.

Nothing happens and you start to call up nil will, then you tremble again as the manus motion straight under your bird and on to your arse, moving straight down to where it was, the hand hesitates for a second when it finds you legs slightly open, then moving again it slips between rubbing slightly but with the jammed posture it can't go where it wants and pulls away. A sudden dashing hopes grips you as feel it strike then a body pushes severe against you and you feel the hand, still under your wench, move slowly round your outer thigh and on to the front of your leg, this time the hand doesn't stop but moves straight to your shaven agglomerate, two digit slip between your leg and your ground up against the body behind you. You start to flush as the finger's breadth expertly stroke across your pussy mound teasing you.

tactile sensation yourself getting damp you move almost without meaning too, opening your legs wider you invite the fingers to do as they will, accepting both fingerbreadth strip inside your now wet twat lips and start to tantalise you rubbing you tingling kitty harder, finding you clit they slip either side 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 bearing and right in front of your sis too !

Trying to command yourself you look at her for the first time and realise she hasn't said anything for ages, seeing her looking down with her mouth wide open you know she can see what's happening to you, she suddenly looks up at you and you flush furiously as your sexual climax hits, you grab the pole between the two of you as wave after wave of joy throbbing through your body making you shake harder with ever rub of the unknown fingerbreadth, the geartrain stagger again as it pulls into a place and the hired man disappears as people get on and off passed you as you still shake.

The train pulls away and now you find decent elbow room to plough rhythm, disappointment flows through you as you realise one of the mass who got off the train was your mystery script ! 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 hand touch the front of your dame and clear that your juice have soaked it where the manus had been. Grinning with superfluity you look at your baby as the train pull in to your post. ‘ Let's get the car'you say to end her speaking.

In the car parking lot you get in the car and she turns to you, ‘ why did you let it encounter'she questions. ineffectual to answer her you just shrug and say ‘ I couldn't service 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 think you reach across to her, ‘ what are you doing ?'she gasps. Placing a finger on her mouth you quiet her, your early hired hand slipping her chick up exposing her gabardine lacy lash, you stroke across it and she jumps ‘ don't, this is wrong'she objects. Ignoring her you stroke again this time a trivial harder and further down between her legs, gasping again she opens them a little wider without being asked. You stroke again and this meter you slip the flip-flop across baring her trimmed snatch, as you look down at it you feel your own pussy throb, touching the trimmed hair you again stroke her pussy. Feeling it dampen as you do you slip a finger inside and rub up and down coating it in her juices as you listen to her trouser and moan low.

fillet for a moment you look at her as she opens her legs wider ‘ please don't stop'she almost begs you, seeming to forget who you are. Again you start to tease her snatch rubbing the length of your finger up and down, finding her clit you tease it running you finger tip round of drinks and over it concentrating all your apparent motion on her clit now you rub strong as she starts to gasp louder, moaning like nothing you've heard before. Suddenly she clamps her second joint together trapping your hand between them and holding your finger against her now rock hard throbbing clit as her orgasm profligate through her body she almost arches herself up and out of the seat, crying out with the pleasure.

Shaking as her orgasm subsides your sister outlet your hand and looks at you shocked, ‘ I can't believe I let you do that to me'she whispers embarrassedly. ‘ it's our slight secret sis'you reply as you start the car and deplume away your fingers still coated in her juices, glancing at her you hear her gasp again as you say ‘ maybe you'd like to try something more with me some time ?'.
