Instant regret...

Beth scurried to the main floor bathroom. She sat on the toilet, pushing out the evidence as best she could until she was confident that she wouldn't leak in her sleep.
I've done a real bad thing...She was suddenly filled with deep remorse. All of her clever justifications melted away as the gravity of what she had done crashed down on her. How could I do that? She put her face in her hands and started to cry, softly. After a few minutes, there was a soft knock at the door.
"Hey... are you ok?" Kyle's voice.
"No..."she whispered. The door opened, and he slipped inside. No sense in having shame about sitting on the toilet after what we just did, I guess.
"Shit...I'm sorry. I fucked up." He sat on the floor, putting a hand on her knee. "I... I should go see about a hotel or something in the morning."
"No." Beth dried her eyes. "No. This was my..." as she looked at him, at his concerned face and sexy body, she couldn't say the word 'mistake.' "I made the moves, Kyle."
"But I let you make the moves."
"I'll get over... how I'm feeling right now. It's just..."
"I feel it too." Why did he have to be so desirable?
"Could you have...like...some flaws, please?" She tried to **** a laugh.
He chuckled, too. "Trust me. I've got plenty of them."
"We can't..."
"No." he was right on the same page. "It's like you said. Restitution, or whatever."
Beth made a bitter sound. "I said that because I wanted to fuck you."
"Well, I believed it because I wanted to fuck you." his laughter was equally bitter. "Now that...we have, let's go to bed, and in the morning... we'll move on with our lives."
Beth nodded, even though she was having a hard time imagining that.
After dressing, Beth slipped as quietly as she could into her bedroom, and then into bed besides Brian. She felt terrible, and guilty and angry. Why couldn't you just... she knew she was projecting, but she couldn't help it. Sleep was long in coming, and the dreams she could remember were troubled and full of vague fears, mostly about getting caught in a tryst.
