Indeed... How to make him submit. She has no control over him, matter of fact, it's he who has the upper hand.
But... Is there such a thing as an upper hand!? No. Everything is just a matter of perspective.
Logically, she should have the upper hand because she was a woman and he was a young man who couldn't control himself.
Men can be controlled through their dicks. All of them are just hungry dogs who want to stick their things inside a woman's body, and what's better than a mature woman!?
A mature woman, who can give them motherly love, who can take care of them, and make them feel warm and happy. A mature woman can provide them with a comfortable life, a comfortable and warm nest to lay on.
Of course, the nature of women is subjective to men. Some men prefer a young woman while some men prefer a mature woman. Some prefer a sexy woman while others prefer a cute woman.
