It sure was

She vaguely had the impression of being lifted and taken upstairs, but couldn't hold much in her mind, and she quickly passed out again as she hit the bed, feeling satisfied for the first time in days. It felt like just moments before she woke up again in the dark, however, to a pleasant, wet feeling in her pussy. What.. what was that? It felt like… a tongue? Was someone eating her out? She felt embarrassed, she was filled with cum! Ooh, but the tongue was so good, so nice and soft on her well-used pussy. Ooh, and it was even licking her punished asshole, it felt like it was cleaning her up! Her pussy throbbed back to life in response as the tongue licked her sensitive areas.

"Mm.. who?" was all she could manage to get out as the tongue continued its work. But her murmured question was returned with an all-too familiar giggle, even if she had only really been hearing it recently.

"Uh, mom, are you?" A swallowing sound was followed by her mother's head coming into view.

"Oh, hello sleepyhead! I was just cleaning you up!"

"Wait, but mom, how could you, I'm your daughter!"

Her mother gave her a withering look in response. "Really, daughter? You have your father and brother's cum dripping out of your holes and you think that's a real line? I'm just trying to get you cleaned up!"

"Uh, but, how did you?"

"Oh come on! You practically told the whole neighborhood they were double teaming you! Not that I'm complaining, mind. Fuck that was hot. They need to do that to me next time."

"Oh, uh, okay. I'm sorry, I just-"

"Now now, darling. No need to be sorry! This is new for me, too. But god, as soon as I had your brother's cock in me I knew it was right! I'm sure you felt the same way, too."

Damn, she was right! And her mom wasn't bad looking, either. She could stand to suck on those nice, big tits. And she bet her pussy tasted great, too. Wait, but she fucked Brad?

"Fuck, I knew it! Was it at the beach?"

Her mother licked her lips as she climbed further on top of her. "Mm, yes, it was so hot getting fucked in the ocean. Gotta love teenagers, they get it up even in freezing water. And then tonight, of course."

"I heard you! Wow, I thought I was imagining things. I thought he needed to sleep!"

Her mother looked sheepish, but just for a moment. "Well, he did. But I.. persuaded him otherwise." She ground her pussy on Katherine's leg and she could feel how wet she was. And now it was her turn to giggle.

"Really, mom? The boy needs his sleep! Sounds like he's not going to get much more around here!"

Her mom laughed and Katherine kissed her. Fuck it, she was a slut! And now she wanted her mom, too.

"MMmm, hello my darling! There's that slut again! Mm, does my slut want to lick mommy's pussy? Maybe some of Brad's cum is still there!"

"Oh yes, mommy! Let your baby clean you out."

Her mother looked beautiful as her body towered above her, and her pussy came down on her mouth. Her tongue went straight into her mother's vagina and fuck yes, there was some cum! She licked it out as her mother moaned and eventually came all over her face before lying down next to her.

"Mm, thank you, darling. I'm so happy we're sluts together, now."

Katherine kissed her mother, sharing some of Brad's cum with her. "Me too, mom." And the pair drifted off to sleep together.
