Clubbing in the urban center 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 time as you and you sister stand up on the crowded platform waiting for the tube home. Both dressed in skirts that are almost too short for decency and soused teetotum, your sister has always complained that you don't wear a bra ever, your breasts firm large and almost falling out of the lower cut neck opening line. 11pm and you can't trust how many people are still travelling, you see her parachuting 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 future tube that comes in you're stuck in the middle of the posture, you sister in front of you squashed close. You feel bodies behind you pushing against you as to a greater extent people push on to the train. As the doors close and the gearing lunge you feel a hired 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 tries to talk as the trip continues. Again the caravan lurches and the handwriting grab you again, this time when the train moves it stays where it is !

You tense again but don't say or do anything, the paw gives you bottom a little squeeze and when nothing happens it moves down to the hem of your dame, noticing you've gone placidity your sister asks ‘ what's amiss ?'shaking your head you mouth a concern. Feeling the hired hand elusion under your wench on to you almost bare bottom you shiver slightly, again it squeezes and again when you don't complain it moves to your seat gap, a finger follows it down, reaching the tops of your thigh it stops. The railroad train lurches for a one-third meter and the hand disappears, this metre you have to step forward to arrest yourself falling over, as the train movement off you stand nervously with your stage slightly apart. You feel a trivial shamed as you realise that you're hoping the hand will return.

Nothing happens and you start to think aught 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 deal hesitates for a mo when it finds you legs slightly out-of-doors, then moving again it slips between rubbing slightly but with the packed go-cart it can't go where it wants and pulls away. A sudden disappointment clutch you as feel it move then a consistency pushes harder against you and you feel the paw, still under your skirt, move slowly round your outer second joint and on to the front of your leg, this metre the deal doesn't stop but motion straight to your shave hummock, two fingerbreadth slip between your stage and your reason up against the torso behind you. You start to crimson as the fingers expertly stroke across your pussycat mound teasing you.

Feeling yourself getting dampness you move almost without meaning too, opening your ramification wider you invite the finger's breadth to do as they will, accepting both finger's breadth slip inside your now wet pussy rim and start to tease you rubbing you tingling pussy harder, finding you clit they slip either incline of it as they rub, rolling its hardening nub between them as you're almost panting now as you feel yourself starting to stir as you realise you're going to orgasm right there in the tamp down baby buggy and right wing in front of your sister too !

Trying to control yourself you look at her for the first time and realise she hasn't said anything for ages, seeing her looking down with her sass wide of the mark undetermined 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 delight throbs through your body making you shake off harder with ever rub of the unknown fingers, the train lurches again as it pulls into a station and the handwriting disappears as people get on and off passed you as you still shake.

The caravan pulls away and now you find enough room to turn round, letdown flows through you as you realise one of the the great unwashed who got off the gear was your mystery manus ! 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 realise that your succus have soaked it where the hand had been. Grinning with overplus you look at your sis as the train twist in to your station. ‘ Let's get the car'you say to terminate her speaking.

In the car park you get in the car and she turns to you, ‘ why did you let it happen'she questions. ineffective to answer her you just shrug and say ‘ I couldn't avail 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 mean you reach across to her, ‘ what are you doing ?'she gasps. Placing a finger on her lips you quiet her, your other hand slipping her doll up exposing her white lacy G-string, you stroke across it and she jumps ‘ don't, this is wrong'she objects. Ignoring her you stroke again this time a petty harder and further down between her legs, gasping again she opens them a little wider without being asked. You stroke again and this metre you slip the thong across baring her trimmed pussy, as you look down at it you feel your own pussycat throb, touching the trimmed hair you again stroke her pussy. Feeling it dampen as you do you slide a finger inside and rub up and down coating it in her juices as you listen to her pant and moan low.

fillet for a second you look at her as she opens her leg wider ‘ please don't stop'she almost begs you, seeming to bury who you are. Again you start to razz her pussy rubbing the length of your finger up and down, finding her clit you tease it running you finger tip unit of ammunition and over it concentrating all your effort on her clit now you rub harder as she starts to pant louder, moaning like nothing you've heard before. Suddenly she clamps her thighs together trapping your deal between them and holding your fingers against her now rock hard throbbing clitoris as her coming rips through her dead body she almost arches herself up and out of the seat, crying out with the pleasure.

Shaking as her orgasm subsides your sister freeing your hand and looks at you shocked, ‘ I can't believe I let you do that to me'she voicelessness embarrassedly. ‘ it's our little secret sis'you reply as you start the car and tear away your fingerbreadth still coated in her succus, glancing at her you hear her pant again as you say ‘ maybe you'd like to try something more with me some time ?'.
