Accidental conversion to big black cocks

Weeks went by with us sporadically having sex and nothing changed. I wanted to use the toy again so badly, but knew I couldn’t. He would know. It was too big for him not to notice. Nothing happened outside of my imagination until about a month later when I was at the tills at work.

It was quiet, getting on towards the end of my shift. I was the only one on the tills and was trying to sort out a display behind the counter, so had my back to the shop.

“Hey cutie,” a customer said as he dumped his shopping at my till. I groaned quietly without meaning to. I was always getting hit on by old men here. My attitude swiftly changed though as I turned and saw a gorgeous black guy looking me up and down. He was over six feet tall, a good five inches taller than me or Craig. He had broad muscular shoulders and the hint of a six pack under his tight shirt. He had short black hair, slightly stuck up at the front and a sweet looking facing. I had seen him before, he was one of the subjects of my ogling over the last month.
