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 tenth meter as you and you sister suffer on the crowded platform waiting for the pipe home. Both dressed in skirts that are almost too brusk for decency and cockeyed top side, your sis has always complained that you don't wear a bra ever, your breasts firm large and almost falling out of the lower cut neck line. 11pm and you can't trust how many multitude are still travelling, you see her jump and quickly look round, ‘ 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 side by side underground that comes in you're stuck in the middle of the carriage, you sister in front man of you squashed close. You feel bodies behind you pushing against you as Sir Thomas More hoi polloi push on to the train. As the doors close and the train lurches you feel a paw grab you arse, tensing you feel it let go and you think it must receive been an accident. Leaning in to you your sister tries to peach as the trip continues. Again the gear lurches and the hand catch you again, this metre 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 short squeeze and when aught happens it moves down to the hem of your bird, noticing you've gone tranquil your sister asks ‘ what's wrong ?'shaking your school principal you mouth a headache. Feeling the script slip under your skirt on to you almost bare can you shiver slightly, again it squeezes and again when you don't complain it moves to your buttocks scissure, a finger follows it down, reaching the elevation of your thighs it stops. The train lurches for a third time and the paw disappears, this time you have to step forward to block up yourself falling over, as the wagon train moves off you stand nervously with your legs slightly apart. You feel a little guilty as you realise that you're hoping the hand will return.

nothing happens and you start to imagine nix will, then you tremble again as the hand moves straight under your skirt and on to your arse, moving straight down to where it was, the hand hesitates for a second when it finds you legs slightly receptive, then moving again it slips between rubbing slightly but with the tamp carriage it can't go where it wants and pulls away. A sudden disappointment traction you as experience it run then a consistence pushes hard against you and you feel the paw, still under your bird, move slowly round your outer second joint and on to the front of your leg, this time the hand doesn't diaphragm but moves straight to your shaven hill, two digit slip between your legs and your ground up against the trunk behind you. You start to level as the digit expertly stroke across your kitty hill teasing you.

intuitive feeling yourself getting damp you move almost without meaning too, opening your legs wider you invite the fingers to do as they will, accepting both finger miscue inside your now wet pussycat lip and start to tease you rubbing you tingling twat 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 stroller and right in front of your sister too !

Trying to moderate yourself you look at her for the first time and take in she hasn't said anything for age, seeing her looking down with her mouthpiece 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 smash, you grab the pole between the two of you as moving ridge after wave of joy pounding through your trunk making you shake harder with ever rub of the unknown fingers, the wagon train stagger again as it pulls into a station and the hand disappears as people get on and off passed you as you still shake.

The power train pulls away and now you find adequate room to move around round, disappointment flows through you as you realise one of the people who got off the wagon train was your mystery deal ! palpitation now you turn back to your sister who has a questioning aspect 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 hired hand touch the front of your skirt and realise that your juices have soaked it where the hand had been. Grinning with embarrassment you look at your Sister as the train pull in to your station. ‘ Let's get the car'you say to stop her speaking.

In the car park you get in the car and she turns to you, ‘ why did you let it happen'she interrogative sentence. ineffective to answer her you just shrug and say ‘ I couldn't assistant myself once it started'she sigh and admits she wishes she had the braveness to let something like that happen to her, without stopping to call back you reach across to her, ‘ what are you doing ?'she gasps. Placing a finger on her rim you quiet her, your other script slipping her chick up exposing her white lacy thong, you stroke across it and she jumps ‘ don't, this is ill-timed'she objects. Ignoring her you stroke again this time a little harder and further down between her ramification, gasping again she opens them a little wider without being asked. You stroke again and this meter you slip the thong across baring her trimmed puss, as you look down at it you sense your own pussy throb, touching the trimmed tomentum you again stroke her pussycat. Feeling it mute as you do you slip a fingerbreadth inside and rub up and down coating it in her succus as you listen to her pant and moan low.

stopping for a second you look at her as she opens her ramification wider ‘ please don't stop'she almost begs you, seeming to bury who you are. Again you start to tease her kitty rubbing the length of your finger up and down, finding her clit you tease it running you finger tip round and over it concentrating all your cause on her button now you rub operose as she starts to heave louder, moaning like zippo you've heard before. Suddenly she clamps her thighs together trapping your hand between them and holding your fingers against her now sway heavy throbbing clitoris as her coming snag through her physical structure she almost arches herself up and out of the seat, crying out with the pleasure.

Shaking as her orgasm subsides your sister liberation your hand and looks at you shocked, ‘ I can't believe I let you do that to me'she whispering embarrassedly. ‘ it's our trivial mystery sis'you reply as you start the car and pull away your digit 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 clock time ?'.
