This guy loved him some bbw mistresses. And he was interested in mistress Anastasia who was one. But the mistress was not in the mood for anything serious so she chose to try jerk off instructions on him. So a little teasing here and a little flirting there later, she had him wrapped around her finger and that is how she made him use jerk off instructions to satisfy himself.
Mistress Anastasia is a BBW girl and she wanted to use her big body to dominate this guy. She wanted him to jerk off and he had no choice but to do it. The mistress had the guy jerk off to her instructions but at the same time, she facesat on him and smothered him making it hard for him to jerk off. She laughed at him as he did it.
