After a busy day, Mariah finally got back to her house. It was a very hot summer day and she just wanted to get out of her clothes. She quickly went into her bedroom and changed. She picked up a tiny red bikini as she wanted to relax by the pool.
When she got downstairs she came across her daughter Amy with her to friends, Mia and Tiffany, as they were going from the pool back into Amy's room. All three girls were in thong micro bikinis and it was very hard for Mariah not to stare at the bodies of these three 20 year old girls.
When she saw her mom, Amy asked, "Hi mom, are you going to the pool?"
"Hi girls! Yeah, I just got back home and I can't wait to dive into the water! Are you finished with sunbathing for today?" Mariah replied.
"Yes, we are going back to my room now," said Amy as she looked at Mariah's bikini. "Oh my god, you look so hot in that bikini mom."
Mariah blushed a little and quickly said, "Thanks honey! I envy you girls so much, look at how sexy and young you are!"
Mia giggled, "Thanks Ms Brown! I would like to be half as sexy as you, at your age!"
"Wow, OK girls, let's get going now, see you later mom," said Amy while laughing.
As Mariah was lying by the pool she couldn't stop thinking about her daughter's friends. Their perfect asses, their firm breasts, their soft skin. Just the thought about how she could lick and fuck them made her instantly wet. Her daughter knows that she is into women, but how would she take if she knew that she was interested in her friends?
After some time of sunbathing she got up and started walking to her bedroom. As she was passing by her daughter's room she heard moaning and saw that the door was slightly open. She looked through and saw Mia lying on the bed while Tiffany was licking her pussy, and her daughter sitting on Mia's face while Mia was grabbing her tits.
Amy saw that her mother was peaking she started screaming, "Yes, grab my tits harder Mia, grabbed them and suck my pussy like you would suck my mother's pussy, you slut."
When Mariah noticed that Amy was looking at her she quickly moved away and went into her bedroom. She lay on her bed and started thinking about what just happened. It was not such a surprise for her that her daughter is fucking her friends, but she never saw that until now.
Seeing Tiffany's stretched ass as she was licking Mia, and Mia's big natural tits was an image she couldn't get out of her head. But the biggest turn on for her was seeing her daughter naked and screaming as she was getting her ass licked. The idea of watching her daughter have sex never occurred to her before, but now she couldn't stop masturbating to the fantasy of seeing her daughter getting fucked, especially if she could watch while have sex in the same room.
In the evening Amy's friends went home and so Mariah called her daughter to come and eat dinner together.
Mariah asked Amy, "So, what did you girls do today after the pool?"
Amy giggled, "Oh, not much, you know, just some girl stuff."
"I can imagine, from what I heard it was a lot of fun," Mariah replied.
"Well, you know me mom," responded Amy. "I am always into new experiences. Also, from what I recall you didn't just herd, you also saw a little bit."
Mariah with a little smile on her face and then said, "Well, honey I just had to see what was so exciting there."
"And, did you like what you saw mom?" asked Amy while looking Mariah in eyes.
Mariah blushed again and quickly said, "Amy! I mean, I would be lying if I said and didn't like it. You friends are so gorgeous! But, you are so much younger than me!"
"You know, they like you to a lot, so I don't think that would be a problem for them," said Amy as her mom was getting up from the table.
"Oh common honey, you are talking nonsense now, common it's time for me to sleep now," replied Mariah as she walked away. "Goodnight honey!"
