Coming to her senses (partially).

David's words cut through Beth's haze of pleasure. Fuck...don't cum inside me! She was on birth control, obviously, but still.... there was something about letting another man cum inside that seemed even worse than what she was already doing.
"Shit!" She scrambled off David's cock, making him wince in pain as she bent his cock downward. "Sorry..." she dropped to her knees, stroking his already spurting cock and doing her best to catch the load in her mouth. Several drops hit her cheeks before she got her mouth around it.
"Fuck...baby....." David moaned.
"Mmmph..." Beth rolled her eyes. What are you doing{if Formation = 5
}, you slut{endif
}?? This is bad. She finished draining David's balls, swallowing the evidence. She grabbed some napkins from the table to clean her cheeks and some of the drops that landed on David. "Sorry... did I hurt you?"
"No baby... you did the opposite of hurt me..." David smiled.
"I'm sorry, I should have told you to let me know..." she gave him a smile. Done is done, no undoing it now.
They cleaned up and dressed up in a semi-awkward silence. After washing up, David looked at Beth and gave a weak smile.
"So."
"Yeah."
"Maybe you should get going."
"Yeah? You sure?" Beth didn't like how she was feeling now, and leaving didn't seem like a terrible idea. Is home going to feel any better?
"Yeah, I can finish up." he stepped toward her to touch her shoulder. "Hey, this... was just a little fun. We can just... put it behind us?"
"Sure..." Beth wasn't sure about that. This was a big transgression for both of them. But she decided to put on a smile. "I'll see you on Monday."

On her way to her car, she got a call from Brian.
"Hey, baby!" she answered. Shit. I didn't call him.
"Hey, I just got home from the event. We wrapped early. Where are you? Kyle said you haven't been home yet."
"Wait... Kyle? Your brother? He's at the house?"
"Yeah... shit I guess I forgot to tell you. He got in today, so he's here."
"That's great." She grabbed the door handle of her car and climbed inside. "I'm sorry, I stayed late to help David. He needs to prep for a big case that's appearing in court on Monday." She turned the car over. "I thought I'd be home before you, so I guess I just forgot to text you."
"Oh, that's fine. I was just..."
"Aw... you were worried about me?" she grimaced.
"Maybe..."
"Well, I'm in the car now, I'll see you guys in a bit."
"Ok, love you."
Beth berated herself silently for what she had done. "Love you too."

When Beth arrived at home, Brian was in shorts and a t-shirt, but he didn't appear to have showered yet, and when she hugged him he smelled faintly of cologne, perfume, and cigar smoke. She didn't mind too much though, and she hoped that he wasn't suspicious of her lingering hug and passionate kiss.
Kyle Jackson, Corporal, U.S. Army (Ret.) introduced himself. He was in jeans and a tight green t-shirt, and despite his extended hand, she gave him a hug instead.
They enjoyed a late dinner, ordering pizza and drinking beer while Kyle and Beth got acquainted. Freshly discharged, he had taken a military transport from Damascus to Tel Aviv, and flown from Tel Aviv to JFK. After a quick 12 hour layover in Manhattan, during which Kyle had crashed with a friend in Brooklyn, he had gotten on a plane to LAX that had gotten in at around noon. He was jet lagged, though the 12 hours spent on the east coast helped a little bit. He would be looking for a job, and an apartment, but Brian was quick to assure him that he could stay with them for a while without a problem.
Beth began to notice Brian's eagerness to show himself as hospitable to his brother, and seemed to be bending over backward to make Kyle feel welcome and loved. Beth would have chalked it up to just being a proud big brother, if it hadn't been for the look that Kyle had given Brian after a particular bout of gushing praise and pride, which had caused Brian to subside into "yeah"'s and "so, anyway..."s. Something weird was going on there.
Eventually, jet lag caught up to Kyle. Beth and Brian headed upstairs to let him sleep.
