Girls who are doing "aidou" (compensated dating) and "waribiki" (splitting the bill) have started standing in front of trains because crackdowns in parks have become stricter recently! They are active safely and securely while going out, with reasons ranging from poverty to sexlessness to killing time!? Furthermore, raw creampie is also OK depending on negotiation! There is no risk compared to standing on the street, and the inside of the train is the best standing spot! The train that is normally used for commuting and going to school is full of standing girls on this day! Men who heard the rumors of this train where you can have sex with ordinary girls, unlike the sex industry, are all leaning forward and looking for girls! Even the awkward sex unique to amateurs feels the most erotic! This is the charm of a standing girl!
