Charles stays on the bottom

To my surprise, Charles rolled over on his stomach with his ass up. Sandra reached over towards the nightstand and came back with a moderate sized black dildo. She leaned in and gently kissed her husband on one cheek.

"Are you ready for it, big boy?" she asked.

"You know what I like, baby," he replied.

My mother-in-law then ran her tongue up my father-in-law's ass, causing him to moan into his pillow. She then started seriously eating his ass. As she did, Sandra reached underneath him and stroked his cock.

"Oh fuck, stop teasing me," he moaned.

"Does daddy need this big cock in him?" Sandra asked. She pulled her face away from his ass and slid the dildo down his crack.

"God, please stop teasing me," he begged. He raised his hips up off the bed.

She turned the dildo and aimed it directly at his backdoor, then pushed it in. His asshole opened for it much quicker than I would have expected, so I was pretty sure this wasn't his first time. He moaned into his pillow again as she slid it in deeper.

"What a good boy," she said as she started fucking his ass. Sandra pulled his dick backwards and wrapped her lips around his shaft.

She was fucking him and sucking him for no more than ninety seconds before he announced he was going to cum. She didn't slow down. Instead, she kept going until she had sucked every last drop of cum out of him.
