Reflective...

The water cascaded off their naked forms as Brian kissed up and down Beth's body. She lifted a leg and put two hands on his head when he got to her pussy, and began to eat her out.
"Brian...." She squeezed his head, and leaned back against the door of the shower. I'm a fool. I'm a slut and a fool. She couldn't get the taste of Denny's cock out of her mouth, despite the mints... the memory of the smell of his body... the taste of his cum. She didn't deserve the pleasure that she was receiving.
When Brian was unable to make her cum with his tongue, they switched to a standing fuck. Her hands pressed against the glass while Brian pounded her pussy. The angle was great for her, but her thoughts kept pushing an orgasm away.
Brian rubbed her soapy back, and squeezed her ass as he pumped. "I love you. I'm lucky to have you. I never want to forget that..."
Beth had to bury her face in his shoulder so he wouldn't see the anguish on her face. What the fuck is wrong with me...
Beth bent over so that Brian could fuck her in a standing doggy-style position. He didn't last very long: it was his favorite. His warm cum splashed her back and ass, and the water washed it away.
"That was great baby... I'm sorry-"
"Please don't apologize anymore, baby." She kissed him and held him close."It's okay." She did. Then why....? She had no answer.
She got him hard again and let him go some more, even though she knew an orgasm was not coming for her. She swallowed the second load, and they finished the shower. They dried off and fell naked into bed, exhausted. Brian seemed thoroughly sated. She was glad he hadn't caught on to her mood, or probed about her own enjoyment. He was snoring soon, and she spent a long time listening to it and trying not to think about Denny.
