"Maybe I should get out of this swimsuit..." she teases, smiling at him.
His hands reinforce the view of her perfect breast and give him extra jolts of pleasure. He aches to cum...
She notices, and says: "No, no, teasing hands! Get him close, but don't let him cum!"
He tries to regain control of his hands, but it's hopeless. The more he looks at her the more he knows he will do whatever she wants. And his traitor hands are already doing her bidding.
