#28777 - The train pulls away and now you find enough room to turn round, 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 hand touch the front of your skirt and realise that your juices have soaked it where the hand had been. As the doors close and the train lurches you feel a hand grab you arse, tensing you feel it let go and you think it must have been an accident. Ignoring her you stroke again this time a little harder and further down between her legs, gasping again she opens them a little wider without being asked.
