Guy sticks to a young girl offering sex for money

A Russian girl is walking along a deserted passage, not noticing how a dude is in a hurry, catching up and trying to make acquaintance. It is cold outside, and a stranger offers her money to go to warm up and have sex. The girl does not agree, says that she is from Russia and got used to the cold weather. The girl sits in the train approached, but the young man wants sex so much that she follows her and offers so much money for how much the girl will make him a blowjob on the train.
