Nathan decided to go for a swim. He had such a crazy morning he had forgotten about his daily exercise and decided a few laps around their Olympic-sized pool would do him good.
He put on his swimsuit, which was a full-body, skintight one-piece that covered everything but his hands, feet, and head. Nathan had bought it himself with his own money, not really wanting to have to ask his Dad (who he didn't like talking to for any length of time anyway) or anyone else because he was embarrassed about not wanting to be seen in anything too revealing. He had some issues with his body, to say the least, and was too shy to even show off his muscular chest if he could help it.
Because he bought it himself with what little money he had at the time, it wasn't made out of the best material, and he had it for a few years at that point, so a few strands and strings were sticking out from general wear and tear.
Once Nathan had his suit on, he went out to the pool. He started swimming, and as he did, he started to feel better. All thoughts of his mother and sisters drifted away from him as he gave in to the feeling of the cool water as he swam even harder than before.
...
As Brooke showered, she could still taste her brother's cum on her tongue. She thought about how she gave her brother a blowjob as she soaped her body.
Wow, Nathan,
she thought as she licked her lips at the thought of it all,
I can't believe what a fucking stud you are, but you're such a loser you don't even know it.
She soaped her big tits, pinching her nipples as she stimulated herself thinking about just how big of a cock her brother had,
Sucking your dick was probably the hottest thing I'd ever done, so taboo and arousing as fuck. Even if you are a loser and a dweeb, Nathan, I know you and Mom have a thing going on, and I'm going to exploit it to get what I want...
Brooke wasn't sure in that minute if what she wanted was her mother or her brother, though Liz was her obsession, the thought of fucking Nathan was turning her on just as much.
Brooke thought about masturbating, but then remembered that James was there and she probably didn't have a lot of time before her mother became his love-sick puppy dog again. She shut off the shower and quickly dressed.
In her room, she glanced out the window and smiled when she saw Nathan was swimming out there in his dorky, full-body swimsuit. She changed into one of her own suits and then ran out of her room to join her brother by the pool.
...
Liz sat in the car for a very long time by herself. At first, she wanted to just leave Bri at the mall out of punishment, but as her anger subsided, she realized that Bri really wasn't to blame.
True,
Liz thought,
She did take advantage of me when Nathan was massaging me. But I wanted my pussy to get licked then, even if I didn't know she was the one licking me. None of this is anyone's fault but mine, or more specifically my Sex Demon.
Liz sighed as she thought of how much trouble her overpowering libido had caused her in such a short amount of time,
Jesus, if I don't get rid of
her
forever, I'll probably end up fucking up everyone's life, especially my own.
And that's what Liz decided to do, lock all her sexual urges away in the back of her brain and throw away the key.
Bri checked four other stores before thinking to check the parking lot and was relieved when she saw that Liz didn't leave without her. She got in the passenger seat, and Liz started the car and drove out of the lot without saying a word.
Bri wasn't sure what to do so she just said, "I'm sorry."
Liz didn't hesitate in replying. "Don't worry about it," she said, sincerely, "But it wasn't very nice of you to pretend to not know about Nathan and me when I
really
needed to talk to someone about it." Liz didn't sound angry about this, just mildly annoyed.
"Well..." Bri said, her voice trailing off, but after a moment she found the words, "Okay, I'm sorry but I saw an opportunity, one I wasn't sure I'd ever get again. I mean," she looked at her sexy friend, "I'm sorry that I have this infatuation, but you are just so beautiful and loving and caring and I just can't help it. You're the kindest person I've ever known and catching you with your son like that, well, I couldn't help but try
something.
"
"So," Liz replied, "You saw me when I lost control."
"If you mean when Nate ate your pussy, no, but I was there."
"Where were you?" Liz asked out of curiosity.
Bri smirked, "I might have been under the massage table, sucking your son's dick."
Liz gasped, "You did?" She took a moment to consider this, "Did he cum in your mouth?"
