"Ran" is a bit of a mouthful. She was showing signs of attention to her stepson from the very first seconds of the video. Generally speaking, stepmothers are the easiest to divorce, they don't mind jumping on a younger guy's dick themselves, while living with his father (a richer man).
These whores, if they need it, they'll suck the first guy they see. The taste of sperm acts like an aphrodisiac on them. And the guy is quite modest, so the hitching of these bitches could not resist. When these two cuties call for a car and promise a free ride, refusing would look like weakness. Like he's afraid of chicks. How could he resist? Well, milking him for a hose is a matter of technique. Sure, the guy cheated on his girlfriend, but she doesn't have to know that.
