Helpful Gentleman helps this Married Duo only on one Condition

Our gentleman was out when he found a helpless couple who missed their train. He as usual showed his kindness to help only on one condition. There was this couple looking distressed on the train station as they have missed their train. As they have nowhere to go and no money, they have to sleep on the station. Our guy lend his help by giving them some cash only if the woman has sex with him. The couple was reluctant at first but then the girl agreed as they were desperate for money. Her upset husband did not want her to do it but she did it anyway and had sex with our guy. He fucked her like a whore right in front of her husband who got angry on her. Finally, our hero fucked her and helped them with cash.
