Home for the night

April, it turned out, had wanted to show him her ass... and she'd lost the thong. It was a great ass all right and Matt fantasized about getting into it. But now he was home and it was super-late.

"No pajamas," Karen told her mom.

"But--"

"You have to be naked for Matt. What if he wants you during the night and you're wearing PJs? How would that make him feel?"

"He can just ask me to take them off."

"No pajamas," Karen repeated. "Now, Matt needs relief and so do I. Since you've had it put to you a couple of times today, why don't you help me out and I'll help Matt."

"But... I'm not a lesbian."

"I'm not either. But I need relief and it seems fair that you help me out since my hands and mouth are going to be occupied taking care of your son."

"I can take care of him."

"What do you think, Matt?" Karen demanded.

It looked like one downside of being 'master of the house' was that he was going to have to sort out some squabbles. Well, Matt could do that.

"First of all, the two of you need to get along without all this fighting. So, Karen, over my knees."

"You mean... yes master."

He stripped down, then piled a couple of pillows at the head of the bed for back support, and gestured his sister to lay across his lap.

"I think ten swats for squabbling is about right. What do you think."

"Maybe fifteen, master."

"Fifteen it is." He gave her the first five quickly, spanking across both buttocks.

"Ten more please, master."

"Spread your legs," he said.

"Of course." She spread, showing her asshole and dripping pussy.

"You like getting spanked, dirty girl?"

"I like getting spanked by you, master."

He slid a finger up her twat and his thumb into her asshole.

"Ohhh."

He made the next five spanks a little harder, enjoying the quiver and tightening in her already tight pussy.

"How does that feel, dirty-girl."

"Hurts, master."

"Well, it is a punishment, after all. You deserve it."

"Five more, please."

He looked over to see his naked mom stroking her twat while she watched.

"Do you like this, mom? Do you want to spank her yourself."

"Could I?"

He considered. "Considering that she's going to be spanking you, I suppose one swat would be okay."

His mom approached and gave Karen a light tap on the ass.

"Come on, you've got to put some body into it."

She swatted harder and pulled back for a third.

"That's enough," Matt said. "Karen is mine. Just like you are."

He massaged Karen's ass for a couple of minutes before giving her three more swats... these a little lighter than those before.

"Okay, off," he said. "Mom, you're next."

"But--"

"Weren't you squabbling with Karen?"

"I guess I was."

"Over my knees."

"Yes, master."

"Karen was just trying to help me while you were fighting against that. What do you think is an appropriate punishment for that?"

"I don't know, master."

"Well, I think Karen and I should share spanking duty. We'll give you ten spanks each."

"Okay." Her voice was soft and submissive.

"I'll go first."

He looked down at her ass. It didn't have the definition that Karen's did but it was a great ass anyway, with a little softness that made it more feminine and defenseless.

"May I put my fingers in?" Karen asked. "The sensation was ever so much stronger when you were inside me."

"Fine," he said.

Karen didn't limit herself to one finger sliding three fingers into her mother's twat and her thumb into her mom's ass.

"Okay," Matt said. "Here we go." He gave her a swat and his mom's body jerked.

"She's coming," Karen announced. "Let me wait until she stops and then I'll spank her, please."

He nodded.

Sure enough, his mom had a second orgasm when they reached eighteen. This time they didn't stop, giving her the remaining spanks while she spasmed and writhed on Matt's knees.

His dick grew hard as he enjoyed the feeling of his mom's ass and the sight of his naked sister wiggling her fingers and thumb in his mom's pussy and ass.

"Thank you, master," his mom said.

"You are welcome. Now, I agree that you should eat out your daughter. She just gave you an orgasm with her fingers and thumb and you need to return the favor. Karen, you may suck me off while mom eats your twat."

"Cool. Mom, kneel next to the bed. I'm getting on my hands and knees to blow Matt so you can eat me from behind."

"Okay."
