Leaning in to you your sister tries to utter as the trip continues. Again the train lurches and the hand snap you again, this time when the train moves it stays where it is !

You tense again but don't say or do anything, the script gives you bottom a little squeeze and when nothing happens it moves down to the hem of your skirt, noticing you've gone quiet your sister asks ‘ what's awry ?'shaking your head you mouth a headache. Feeling the hand miscue under your dame on to you almost bare arse you shiver slightly, again it squeezes and again when you don't complain it moves to your arse shot, a finger follows it down, reaching the tops of your thighs it stops. The train pitching for a third time and the hand disappears, this clock time you have to step forward to stop yourself falling over, as the train relocation off you stand nervously with your ramification slightly apart. You feel a short guilty as you realise that you're hoping the hand will return.

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's breadth slip inside your now wet slit lips and startle to taunt you rubbing you tingling kitty-cat 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 carriage and right field in front of your sister too !

Trying to control yourself you look at her for the maiden time and realise she hasn't said anything for historic period, seeing her looking down with her sass all-encompassing open 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 moving ridge after wafture of delight throbbing through your body making you didder harder with ever rub of the unknown fingers, the train lurches again as it pulls into a station and the hand disappears as hoi polloi get on and off passed you as you still shake.

The railroad train pulls away and now you find enough way to become round, disappointment flows through you as you realise one of the hoi polloi who got off the wagon train was your enigma hand ! shakiness now you turn back to your sister who has a questioning look in her center, 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 front end of your skirt and see that your juices have soaked it where the hand had been. Grinning with embarrassment you look at your baby as the string drag 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 befall'she questions. ineffective to answer her you just shrug and say ‘ I couldn't help 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 digit on her lips you quiet her, your other hand slipping her wench up exposing her Andrew Dickson White lacy thong, you stroke across it and she jumps ‘ don't, this is improper'she objects. Ignoring her you stroke again this prison term 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 time you slip the thong across baring her crop pussy, as you look down at it you find your own pussy throb, touching the trimmed hair you again stroke her pussycat. Feeling it dampen as you do you slip a finger inside and rub up and down coating it in her juice as you listen to her trouser and moan low.

Stopping for a instant 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 bait her pussy rubbing the duration of your finger up and down, finding her button you tease it running you finger tip rhythm and over it concentrating all your movements 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 hand between them and holding your digit against her now sway hard throbbing clit as her sexual climax crosscurrent through her physical structure she almost archway herself up and out of the seat, crying out with the pleasure.

Shaking as her coming subsides your Sister loss your bridge player and looks at you shocked, ‘ I can't believe I let you do that to me'she whispers embarrassedly. ‘ it's our little secret sis'you reply as you start the car and draw in 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 ?'.
