Cat took a step and was surprised at what she saw, he was stroking his groin and touching his balls, moaning at the same time, but it was as if he realized she could hear him moaning, he lowered it. He kept stroking and biting his lower lip and silently groaned. Cat was still in shock at what she was seeing, it wasn't like she hadn't seen a man masturbating before but it felt somewhat strange.
Why was he doing that? When he knew that they were going to have sex.
Cat felt kind of awkward and kept looking at him and then, she silently walked away and then she went back again and took a peek at him again. He was so aroused and she also was getting excited at what she was seeing and she hoped she wouldn't get caught. He kept stroking faster and faster in the bathroom and moaned, and kept muttering some words she couldn't hear. As he kept going faster, he groaned and released in the bathtub and panted.
