Poolside sex.

Beth could feel Kyle's cock, rock hard, between them as she straddled him in the water. He was kissing her and groping her breasts, while his strong hands pulled her ass close, pushing his cock against her clit. She moaned loudly in his ear.
"Fuck...Kyle... what are we doing?"
"It's called sex, Beth. Maybe you've forgotten?"

Kyle put her on hands and knees at the pool's edge, and fucked her. He pounded her pussy with **** and gusto. She moaned and panted and bucked her hips backwards to meet his thrusts.

"What....about....Brian?" she moaned...
"Fuck him... he fucked my girlfriend... and besides...he's not...taking...care...of....businesss..."
"Wha....oh fuck...what?" She was still drunk, but she was lucid enough to understand him. "Stop." She turned around to look at Kyle. "What did you say?"
"Brian... when I came home from Infantry training, I got an earlier flight that I expected." He sat on the steps of the pool. "When I came home, I wanted to surprise my girlfriend. Except, she surprised me. She was getting railed by my brother."
"Are you serious?" Beth couldn't believe it. Brian was a straight arrow. Frustratingly straight at times.
"I nearly broke his arm. We roughed each other up good. And neither of us saw her again. We didn't speak for nine months. Eventually..." he blinked hard, and rubbed his eyes. He was just as wasted as she was. "We made up. At least... I told him I forgave him."
Beth crossed her arms. "You don't really forgive something like that."
"He made an effort. And besides, she was a slut. I'm sure she made the moves on him."
"Doesn't make it hurt less." Beth rubbed his knee. "So... that's what this is about.... **** fuck?" She tried not to sound bitter.
"No..." he sighed. "Okay, I admit...It was a little bit...a little part of it." Kyle smiled. "Mostly...it's just why I don't care about hurting him."
"Well, then I guess you better fuck me good and make it worth it." Beth smiled.
Forty minutes later, the two of them made their way quietly back into the house. Beth had a load of cum in her pussy, and another load in her stomach. She gave Kyle a long, sensual kiss.
"Thanks for the good dick."
"Any time."
"Never again." Beth shook her head.
"Promises." Kyle chuckled.
Beth went to the bathroom to wash up, and expel some of the evidence. {if Shame > 84

}She slipped into bed, and Brian murmured in his sleep. Beth rubbed his back. "Are you okay, baby?"
"mm...yeah....g'night...love you.."
Beth sighed. I can't believe you fucked Kyle's girlfriend. I can't believe I fucked your brother. "I love you, too."
