Thomas deflowers his sister.
Somewhere in the craziness of the next moment, Erica yanked the sweater over her head and stood topless while Kevin assailed her tits. She straddled his legs and sat in his lap while he finished. As soon as his senses returned, Kevin sat in stunned silence.
"Wow. That was fantastic," Erica moaned. "Now it's my turn."
She slid backwards and got on her knees between his legs. She unbuttoned his pants and pulled down the zipper. Kevin watched, unable or unwilling to stop her as Erica pulled his dick out. It was long and hard and throbbing.
"God, Kevin. You're huge. Why have you been hiding this from me?"
She stroked him a couple times and kissed the head of his cock. Erica licked him from the base all the way to the tip, then down and back up again. She felt the cock twitch just as she put her lips on it and took the head into her mouth. As if in slow motion, she lowered her head until the entire erection disappeared.
Kevin felt it hit the back of her throat. Then he felt her tongue. He leaned back and closed his eyes.
Erica sucked on the thick shaft like it was her favorite candy and her intent was to make it last all day while still enjoying every bit of it. The pressure she applied with her lips was just right-tighter than a pussy, but not enough to hurt. Experience with younger guys was paying off with the man she wanted at that moment.
Any half-hearted attempts Kevin made to stop Erica were long forgotten as he reveled in a sensation that he had not felt for far too long. All the times he had looked at her in the hallway and imagined 'things' now seemed trifling. The reality of his cock inside her mouth trumped any fantasies that came before.
He thought about when he touched her leg on the ladder, and touching her bare ass in his office. He thought about her tit coming into view and the taste of it in his mouth.
And suddenly, he was about to cum.
"Oh Jesus, Erica. Stop! I'm...I'm...going to...ahhhhhh."
She took the cock in her hand and fondled it furiously. She aimed it at her face and waited with glee. Just then, Kevin's phone buzzed. He knew it was his secretary on the intercom and ignored it, as if he had a choice.
The orgasm was on him so quick he could only clutch at the arms of the chair and let the first gush of cum spew onto Erica's face. Immediately, a second spurt spilled more white cream all over her. More shots caused streams of cum to slip off her chin and onto her tits. Kevin's groans, which came loud and fast at first, grew less frequent as his cock emptied.
Then they heard the office door open.
Kevin looked at Erica in complete panic. "I thought you said..."
"Oops. Guess not," she shrugged.
In the doorway, Julie muttered an unintelligible gasp upon seeing the scene behind the desk. After a moment frozen in time, she pivoted around and slammed the door shut on her way out.
"No, I don't believe that was the first time, Kevin," Julie sobbed. "But why? After eighteen years. How could you?"
"I swear, Julie. It never happened before and it will never happen again. How can I convince you?"
Negotiations between the couple went on for another fifteen minutes, with Kevin gradually getting Julie to forget the thought of divorcing him. In the end, she had the last word.
In a tone of complete finality, she said, "If I ever find you with her again, or any woman, that will be the end of this marriage and your career. Understand?"
But Erica was not part of the debate nor did she agree to anything. The rush she got from the liaison with Kevin in his office, and the resulting look on Julie's face, only strengthened her resolve. It took a week, but eventually she had another plan. And the stakes were increasing.
It was a cold, snowy Saturday afternoon when Kevin unexpectedly heard the front doorbell. Julie was shopping and would have come in through the garage. So he trudged to the door fully expecting to find a kid trying to sell something or a religious zealot trying to save him.
He was more than a little surprised to find Erica smiling back at him on the por
