Kim's washing machine has broken down. Her husband is out of town for a few days, so she phones for a repair man to come round and fix it.
He turns up on her doorstep in his overalls; a tall, muscular black guy. Kim shows him into the kitchen and after just over an hour, the washing machine is working again.
During that time, Kim had stood chatting to him whilst admiring his firm body. Kim is an inveterate nymphomaniac and can't help herself from flirting with him. There has been more than one occasion when her husband has been away that she's ended up in bed with workman or courier.
She pays him for his work but can't stop herself from letting him know she'll be giving him a little extra for his a trouble.
She grabs hold of his cock through his overalls. She can feel that it's huge even as it's soft. She rubs it through his clothes as she feels it getting harder.
Kim unbuttons his overalls and works her hands inside and down his muscular torso. She pulls his now hard dick out of his clothes and gasps as she sees just how big it is. She drops to her knees and begins to fellate him.
Her left hand works up and down the shaft of his cock as she stuffs the swollen tip of it into her mouth. He sees the ring on her third finger and smiles.
"So, you're married, huh? What would your husband think if he saw you now?"
Kim takes his cock out of her mouth to say "Oh, he'd go mad. Please sir, don't tell anyone that I'm doing this for you."
"How long have we got before he gets back?"
"He's away for a few days. Please, I'll do anything to keep this between us." pleads Kim.
