Her husband indulges in Casey's changes

Within moments, Casey was wearing her collar and nothing else, and was on her knees, sucking her husband's cock eagerly. His cock felt so good in her mouth, and down her throat. It kind of felt like she'd barely ever done it, her throat protesting as she swallowed him down, but that was crazy. She was an insatiable cockslut, and she loved giving him blowjobs. And taking him up the ass.

"Enjoying yourself?" her husband asked.

"Always," Casey mumbled, as she pulled her lips off of his cock, "I always love sucking your cock, Master." She dragged her tongue up the underside of his cock with a moan, "Spending some time worshipping your cock is always a great way to end the day..."

She took him back down her throat, and it wasn't long before she was moaning as he came down her throat. She eagerly swallowed everything he gave her.

"Mmm...thank you so much, Master..." Casey mumbled as she pulled off of his softening cock, her hand quickly wrapping around it to stroke him lightly, wanting him to get hard again, "Your cum is so tasty..."

She dipped down to his balls, her tongue sliding all over them, and William let out a groan as he watched her, "Can't get enough, huh?"

"When can I ever get enough?" Casey asked back, grinning up at him, "You know me. Absolutely insatiable..."

His cock was already starting to stir as Casey licked and sucked on his balls. It didn't take long for her to get him hard, before she stood up and grabbed his hand, tugging him towards the window, "Why don't you show the neighbourhood how good you can fuck my ass, Master?"

Casey leaned up against the window, pressing her tits against it, and her husband didn't wait before he was pushing into her ass. Casey let out a loud moan as he did so, feeling that cock of his sliding into her ass was yet another thing she could never get enough of. Again, it felt oddly...new, like her ass wasn't used to it, but she knew it must've been used to it. She loved anal, he certainly fucked her ass all the time...even if she couldn't remember when he did...

He fucked her ass without holding back, making Casey just moan more and more, "You love being my fuckpet, don't you, Casey?"

"Yes, Master!" Casey moaned out, "It's all I crave for! Being your pet is my entire purpose in life, Master..."

"Good girl," he praised, and kept fucking her ass. While his attention was entirely focused on her, Casey watched through the window as the college boy that lived next to them, Jack, came home, and his eyes met hers as he stepped out of her car. She just grinned at him and winked as he eyed her tits. He'd always been nervous around her, it was clear he liked her. And he was kind of cute...

But as her husband came in her ass, Casey's attention was pulled away from Jack, and she moaned out as she came with him, eyes rolling back in her head due to how good it felt.

"Mmm...so good, Master..." Casey hummed.
