She rolled her eyes up into her head, as she opened her mouth and took in the smelly black cock. It had a cheesy taste, like maybe the guy hadn't washed in a long time. But the steady pressure on the back of her head, would not let her retreat. Finally she gave up resisting, and took as much of the black cock into her mouth as she could handle, without gagging.
She could sense that her husband was breathing real hard, and his cock was poking her in her breasts, as she kept sucking on the black guy.
All of a sudden, she sensed that the black guy was going to cum. His frantic fucking of her mouth had stopped, and she felt his cock pulse, as it started to shoot his cum into her mouth.
Her husband had a firm grip on her head, so she could not pull back. To keep from having the cum go up her nasal passages, she started to swallow the cum. It had a tangy taste to it, and there was a lot of it, but she kept on swallowing. Finally, the black guy stopped cumming, and he pulled out of her mouth, and pulled back through what she would find out later on, was the glory hole in the wall.
Her husband let go of her head, and she sat up abruptly, to catch her breath. She could see there was perspiration on his forehead. Well.... there was on hers too.
Just as she figured it was all over, there was a knock on the wall, and she looked down, and saw another black cock come through the hole.
She looked at her husband, who just smiled, as she lowered her head down. She knew she was now a black cock sucking wife. And you know what? She thought that this might be fun, after all!
