Bert woke up when he heard a commotion downstairs. He looked across the bed to see if it woke his wife, Agnes. She was gone. Then he remembered. She had gone out drinking with her sisters, Virginia and Edith for her birthday. They were all in their late fifties or early sixties and retired. His wife had short brown hair that was starting to gray. Her boobs were freckled, but saggy. Her best feature was her great ass.
Bert got out of bed and went downstairs. Apparently, they hadn't had enough to drink and had opened another bottle of wine.
"Just how drunk do you plan on getting?" Bert asked.
Startled they all looked up.
"Oh Bert. Did we wake you? I'm sorry," Agnes said.
"Yeah, we're sorry Berty wirty," Edith said. Then all the women giggled.
"Agnes, you said you'd be home hours ago, you're late."
"I know but it's my birthday. I thought it'd be okay."
"Well, it was your birthday yesterday. And it doesn't matter. Late is late. You know what to do."
"But my sisters are here Bert."
"Good. I have a mind to discipline them too."
"Don't you dare!"
"Are you questioning me?" Bert asked.
"No," Agnes said meekly.
"Get over here!"
Agnes came over and lay across Bert's lap. She was wearing a skirt with a plain white shirt.
Virginia and Edith watched with open mouths as Bert began to spank his wife on her ass.
"So you think you can be late and talk back? I'll teach you to talk back!" Bert said smacking his wife on her butt. Then he lifted her skirt up and spanked her through her underwear. They were plain white granny panties.
"Please Bert it's my birthday," Agnes said.
"Then I guess you need to be in your birthday suit. Let's go off with it."
Agnes stood up and started removing her clothes.
"Agnes stop. What are you doing?" Virginia said. She was standing next to Agnes, so Bert reached over and pulled her onto his lap.
"Another one with a mouth huh? Let's see how you like it," Bert said and started spanking Virginia's butt. She was wearing a dress and soon he pulled that up and was spanking her butt covered only by a thong. Her ass wasn't as nice as Agnes's but it was still pretty nice.
Bert could feel her big breasts on his thigh. Her nipples were getting hard.
When Agnes was naked Bert told her to stand in the corner. She obeyed.
"You know this thong isn't really doing anything anyway," Bert said rubbing his wife's sisters ass. "Let's just get rid of it." He quickly pulled Virginia's panties off.
Bert alternated between each cheek. They were starting to turn pink. Soon they'd be red. At some point Bert felt wetness on his leg. He stopped spanking Virginia and was rubbing her ass. Bert then slid his finger down Virginia's butt crack to her shaved pussy. Yep, she was wet alright.
"I think your sister likes to be spanked. She's all wet," Bert said sliding his finger inside Virginia's pussy.
"Uh!" Virginia gasped. "Stop that. I'm not turned on."
"You could have fooled me," Bert said sliding his finger in faster and faster. Everyone could hear the wet sound her pussy was making as Bert slid his finger inside her.
