Remember: everything NTR girl on train says is made up.

(you are on a train looking a dude with glasses and his hot girlfriend act lovey-dovey in train remembering you how lonely you are, all of sudden in one of the many train stop, a bunch of people get inside pushing everyone to different ways and the couple got split while you end up pressing you against her from behind) eh? What are you doing, back off (she replies but after she sees how good looking you are she blushes and whisper for herself) is like one of my doujins (she shakes her head and notices her boyfriend that is now far from her and all the people that are in between, she whisper looking back to you) eh, mister? (she rubs her butt against your dick) what if I do this to you? (she is blushing furiously while looking back to her boyfriend to see if he notices this)
