The family had all gone to their compound on Block Island. The two brothers were both dating very attractive and intense women who happened to absolutely hate each other. The two women were both 23 years old, bisexual, and very sexually aggressive. After several tense days, late in the evening, well after midnight and long after everyone's parents went to bed, Theresa and Matt walked into Kevin and Kristin's room. Theresa simply looked at Kristin and said, "We need to end this. Right now."
Kristin stood up, not one to shy away from another woman. "Here?" she asked.
"No, the back guest house. It's shut for the weekend, no one is using it."
Kristin nodded, "Okay"
Theresa went to leave but turned back and said, "Oh, bring your dick."
Kristin set her face and looked at Kevin, "She has no idea who's she's messing with. I have outfucked so many girls in my lifetime, she has no idea." She walked over to her dresser and started rifling though her clothes.
"What are you doing?" Kevin asked.
"Getting some stuff I need, specifically my lube and the dildo."
"You have a dildo here?"
"yes, I use it when I fuck your sister. You didn't know that?"
"How would I know that? When do you fuck my sister?"
"When she's horny. Not for discussion now. I need to go. I'll see you when I get back." She paused, hiked her skirt up and shoved a tube of lube up inside of her vagina and squirted it inside.
"Wait, she said to bring your dick!"
Kristin laughed. "You jackass, she meant THIS." and she waved the huge double dildo in front of his face.
She walked downstairs quietly and out the back door. Kevin ran and got Matt who had gotten their sister, Sylvie. Matt turned to Kevin and said, "We're going to watch through the window, you wanna come? "
Kevin nodded but then said to Matt, talking to Sylvie at the same time, "Did you know Kristin and Sylvie fuck?" Sylvie started to laugh.
Matt said, "Apparently so do Theresa and Sylvie."
"What the fuck? " both guys said.
"Fuck you, we're just fucking, there's no relationship. Do you guys wanna know who's going to win or do you want to watch and find out?"
"What do you mean" they both asked as they started to walk quietly across the wet grass.
"I fuck them both, there's no doubt who's going to win, in my mind."
"Don't tell us," said one.
"Yeah, I wanna watch" said Matt, "Besides, Theresa apparently did this all the time in her sorority in college and never lost, I think it's pretty much locked up."
"Suit yourselves." Sylvie said. They heard the door close at the back guest house. They got to the big window looking into the master and saw the two blondes naked, making out and rubbing the other's pussy.
"For what it's worth, Kevin whispered, Kristin said she outfucked girls all the time herself. Maybe she can keep up with Theresa."
The two women were stumbling about and they landed on the bed. They ground their pussies together for a moment and then grabbed the dildo, each inserting one end.
They arched their bodies and drove their hips toward one another. They both grunted and squealed.
Stalemate.
Another thrust.
Grunting.
Another thrust and suddenly the cock plunged into one of the women's pussy. "OOOOOHHHHH MY GOD!"
The two women pressed together. One woman mounted the other and begun to thrust wickedly. The woman on the bottom squirmed and thrust back and struggled. They kissed and squeezed each other's breasts. The woman on top thrust repeatedly until the woman on bottom orgasmed. It wasn't over. The woman on top kept fucking as the woman on bottom grunted, thrashed and tried to fuck her opponent back, but the fight was as one sided as fights could get. The woman on top thrust and grunted and the woman on the bottom moaned and chirped as she was ravaged. She came repeatedly. The woman on top was drenched in sweat from the exertion but after 15 or so minutes of absolute sexual dominance, the woman on the bottom sobbed out her surrender. The woman on top laughed and got up, easily pulling the cock out of her foe and then reaching between her legs and pulling It out of her own pussy. "Don't fuck with me anymore, I'm the alpha bitch now, Theresa." Kristin got up and walked out of the room, through the front door.
On the side of the house, Sylvie smiled and showed her brothers the palm of her hand, in red lipstick, she had written the letter K. "Told you" she said.
And she looked at Matt and Kevin and continued, "Kevin, go fuck your girlfriend, she's gonna be really horny. Matt, go pick up the pieces, she's gonna need some comforting, I'm going to masturbate."
