Now here she was making love to his cock and obviously looking forward to feeling it right up her fuck-hole.

Jack sat on the lounge watching the action, his own cock as hard as it had ever been. He had often seen Cass in action with other men, but tonight she was really turning on the sex.

Her hand was busy running under Guy's body to his asshole while she held his cock around the base with her other hand. She flicked her tongue over the head, then she opened her mouth wide and sank her head on to it.

It wasn't easy. Although she opened as widely as she could, she could not help scraping her teeth along as it went into her mouth.

"That's it, honey," her husband encouraged. "Let Guy see what a great cock-sucker you are."

It did not worry Guy that Cass's teeth were scraping his prick as she bobbed her head up and down on it. She tried to flick her tongue around it, but it was so big she had difficulty in moving her tongue around its bulk.

It was now going well down her throat as Guy fucked it in and out of her mouth, and Cass was breathing noisily through her nose as she took in and exhaled great gulps of air. She sucked her cheeks in to increase the pressure on Guy's cock.

"Oh my god, she's marvelous!" Guy gasped. "I've never had my cock so far into a girl's mouth before!"

"She's waiting for you to cum down her throat," Jack said.

Cass continued to gobble his cock hungrily, grunting her agreement with what Jack had said. Guy put his hand on the back of her head and combed through her silky hair with his fingers.

His bloated cock was touching the back of her throat and the sensation of her throat muscles gripping it sent a shock through his body. Saliva was running down Cass's chin as Guy's cock-head touched the soft tissue of her throat.
