Reveling in her own depravity, Cathy began to work her lips back and forth along the penis that filled her mouth. She nibbled every contour with greedy skill. Her lips clung to the fleshy surface of his cock like a second skin. Their pressure was just enough to keep Rick feeling a little bit off balance every second. She was making the blood pound faster through his cock. She was provoking a lewd tingling in his balls, still tucked safely away inside his pants.

Impatiently, she dug into his fly and pulled out the hairy sacs of his testicles. Her tongue lapped hungrily all the way down the underside of his penis. When she reached his balls, she took the heavy globes into her mouth, one after the other, and sucked them eagerly.

"Aaiiieee! Jeez-z-z! Holy shit, what are you trying to do to me!"

He grabbed hold of her hair and tugged on it savagely. Too much more of that ball-sucking and he'd be shooting his load into her mouth right now! She wasn't going to get off that easily! "Come on, Miss Coke! Suck my cock! Do it to me!"

With the cruel guidance of his hands, she bobbed her head up and down over his turgid cock. She enjoyed even the pain that the strain on her scalp brought her. His urgent movements indicated, he was enjoying her cock-sucking as much as she was. She loved making herself slave to a penis this way! She loved the ever-present threat of quarts of thick hot juices over pouring, spilling down the back of her throat. She liked to revel in the masculine presence in her mouth – hard, demanding cock!

Rick smiled as he watched the shadowy picture of her head making its obscene way back and forth along his penis. She was so totally absorbed in what she was doing. She was like a willing slave come to worship at the altar of cock. There was something that would make the picture even more perfect for him. "I want to see your tits, Miss Coke! I want to watch them move while you suck me!"
