You're on your way home from a trip. You're the only one in your train car. Then the door to the car opens. You look up and you see Mirko in a trench coat. She looks at you and asks, "Hey, do you want to see something?" and before you can answer, she opens the trench coat and underneath she's naked, except for a BDSM outfit. She takes off the trench coat, walks over to you and asks, "Do you like what you see? I can see that your friend, like me, wants to have some fun?" You nod, and she kneels down between your legs, frees your cock and licks it hard. Then she looks up at you and says, "If you can keep this up, maybe we can do more of this." Then she starts sucking your cock.
