His phone...

David pounded Beth's pussy with **** and vigor, going deep and stroking long, groping her hanging breasts and even pulling on her hair.
"Damn, David, I ne..e...ever would have guessed you were su-u-u-ch a beast..."
"I'm sorry..." he slowed down, rubbing her shoulders. "I didn't mean to..."
"Don't fucking stopppp, baby...." she purred. "I love it."
Just as David began to pick up his pace again, his phone buzzed from the pocket of his pants.
"Shit..." he stopped fucking her, and pulled the phone up to his face. "It's her."
Beth put on an indignant frown. "Fuck her..."
David put a finger to his lips, and hit the button to answer. "What is it Kim? I'm still working..... mmhmm...I see."
While he was talking, Beth slipped off the couch and crawled sensually over to kneel at his feet, grabbing his cock and pulling it into her mouth. She hummed and slurped, and David shot her a look of alarm. "Well I didn't appreciate....thhhe accusation." The irony of the statement was not lost on him, Beth was sure. She rubbed his balls and sucked harder. "You do this all the time, honey. You flip out on me with these accusations and then try to make up for it with sex, without changing your behavior." He put the phone against his shoulder to mouth "Fuuuuuck" as Beth deepthroated him. Beth heard the words "trust that slut." pipe up over the sounds of her blowjob. It took every ounce of self-control not to shout something that would ruin both of their lives. "If you're still talking like that, then maybe you should stay there...unnnn....til you calm down."Beth sucked on his balls while stroking hard. David's hand was suddenly on her head, stroking her hair. She looked up to see that his eyes were squeezed shut and he was shaking his head.
"I'm going back to work. We'll talk about this when I'm done. Good bye, Kim." He hung up the phone and tossed it aside.
"What a bitch..." Beth said, rubbing his cock with both hands.
"You... are trouble, girl."
"Judgment for the plaintiff. Maybe you should award some punitive damages."
"...it's quite unfortunate how hot I find your legal double entendres..."
"Isn't it?"
They resumed fucking, and David was even more aggressive: pushing her face into the couch and really ramming her good. His phone buzzed a few more times: short buzzes indicating text messages. He didn't stop again. Beth finished him in her mouth, and swallowed. "Got to destroy the evidence." She said with a wink.
David grabbed his phone while she laid back on the couch, basking in the afterglow of cheating sex. Somewhere, distantly, her conscience was yelling at her. She would have to listen later, but not now. It was still too euphoric.
"Huh... texting me. 'I'm sorry.' 'you're right, I shouldn't assume things' 'you've always been good to me' 'why don't you come to the Sheraton... let me apologize.' It's like she didn't even hear.... Okay this is a picture of her in new lingerie..."
Beth chuckled. "Men."
"Hey, I didn't say I forgive her. Besides... we kind of just made her not a liar."
"But we hadn't when she made the accusation. Ex post facto and all that."
"I should probably talk to her..." David was rubbing sweat from his forehead.
