Sylvia's mother and Jason were startled awake in the morning by the sound of a soft knock on the bedroom door. Shocked to have someone intrude when they were together, she and he stared at each other wide-eyed for a few seconds, their hearts pounding.
"Mom, it's Brenda," Sylvia's sister called softly. "I just wanted to tell you I was leaving early, so you wouldn't worry if you woke up and I wasn't here. And don't worry, Sylvia's still sound asleep."
Both Jason and Karen relaxed at the sound of Brenda's voice. Still, both of them looked uncomfortable. Even though both of them had talked with her about their affair, it still felt odd to have her actually acknowledge it.
"Did you have your breakfast, honey?" Karen called.
"I'm gonna grab something with Helene on the way over," Brenda replied. "See you guys later." The next sound they heard was footsteps going down the stairs, then the door opening and closing.
Karen and Jason lay in each other's arms, breathing hard and not saying anything for a few moments. Then a smile formed on her face and she began giggling. Her giggles escalated and, before long, she was roaring with laughter and tears were rolling down her cheeks.
Jason, a little confused by how Sylvia's mother was acting, lay there next to her, wondering what she found so funny. He'd been scared until he heard Brenda's voice. What if it had been Sylvia? But, as Karen laughed, her nude body, which was pressed against his, shook, rubbing her warm, silken skin against his. And, as it always did, contact with her body, caused a reaction. His penis began filling with blood and stiffening. He hunched his hips back a little, to keep her from feeling his erection and watched her as she continued to laugh.
At last Karen's laughter began to calm, then it stopped. "God," she said. "Were you as scared as I was when Brenda knocked on the door?"
"You better believe I was!" Jason replied. "I was so scared I thought I'd wet myself!"
"I'm sorry for laughing, my darling," Karen said, caressing his face gently with her slim fingers. "It's just that, for some reason, the situation struck me as totally silly. I'm not sure why."
"Maybe it was just some kind of nervous release," Jason suggested.
"I guess you're right, my darling," Karen said. The look on her face, which he thought was even prettier than usual because it was flushed from her laughter, grew serious. "I'm sorry about how I acted last night," she said softly.
