A little guilt and a little caution.

"I've been trying to eat right...." ...for the wedding. Beth felt a pang of guilt. Fuckkkk. She had done a very bad thing, and the justifications and pleasures of it were starting to melt away into remorse and anxiety.
"What's wrong?" Derek was using a wet wipe from his center console to clean himself before tucking his cock back into his pants.
"Everything that just happened..." Beth sighed.
"Hey...you started it."
"I know!" Beth snatched a wet wipe of her own to wipe her seat down before putting her clothes back in order. "I'm not blaming you. I'm just..."
"It's ok. You're not there yet." Derek sounded a little smug. "I can take you back to your car, if you want."
Beth didn't like the implication he had made. This was just a lapse in judgment. "Listen..."
"Beth, you don't have anything to worry about. I don't need to tell anyone anything. Besides... you already know what you want." He started the car and pulled back onto the road, turning around at the next exit to head back towards the restaurant. For her part, Beth said very little, lost in thought. She wanted to deny what he was suggesting. She wanted to go home and forget this had happened. Back to your lackluster love life? She shook her head angrily. Lackluster for now. It's no excuse for doing... the images, the smells and the taste were still present. She couldn't fully relegate them to a place of regret. She couldn't deny that a part of her wanted to go back to Derek's place and do more. No. Even after fucking up that badly, I can still be cautious.
When they returned to the restaurant, Derek made the direct offer she was worried about. "I can guarantee you'll have a good time."
"I should go home. Thanks for dinner."
"You're welcome. Let me know when you're ready for dessert." His wicked smile let her know that this was not going to go away. I've put my foot in it...well my mouth around it, anyway. He's never going to let it go.
Beth stopped at a convenience store on the way home for a bottle of mouthwash to wash the taste of dick out of her mouth. When she arrived home, Kyle Jackson, Brian's brother, was awake. They exchanged cordial greetings and got to know each other a little bit.
Kyle Jackson. Corporal, US Army, had been honorably discharged after a four year tour. He'd been deployed, first in Iraq, and then Syria. Now that he was done with his duty, it was time for him to fit back into civilian life. He wasn't eager to see his and Brian's parents, for reasons he didn't seem to want to get into, and Beth didn't press. That's why he was crashing here, and not in Newport Beach with them. He would start looking for a job, but he was really excited to be home in time for their wedding.
Beth gave him the short version of how she and Brian had met, what she did, and where she was from. She was coming to the strange realization that Kyle was very charming. He had a slightly "rough around the edges" demeanor that she supposed was typical of recently discharged soldiers, but his politeness was refreshing and his smile was roguish. He had much of the traits that she found attractive in Brian, with the additional benefits of youth, and the physical training of a soldier. She knew, from Brian, that Kyle had been a bad kid: ****, fighting, eventually a stolen car and a joyride before an arrest. Community service, instead of jail time, had led to enlistment. She got the sense from Brian that his parents had pushed him into the military as a way to "get rid of" the problem. {if Formation = 4

Beth tried not to notice how much more fit and muscular Kyle was than Brian, or his boyish charm that she enjoyed. Jesus Christ, girl. Get a grip on yourself. With that thought, she excused herself to partake in one of the hottest showers of her adult life, to burn away her suddenly uncontrollable libido. When she came downstairs, Brian was home, embracing his brother in the living room.
