They ate the lunch they'd brought, swam again, and made love again before they got dressed and headed back for the cabin. Both of them were even more acutely aware of the changes that had taken place in their relationship during the time they'd spent together since arriving at the cabin, and each of them was lost in thought, trying to come to grips with what those changes really meant while they made their way back through the forest.
When they walked into the cabin, they found Brenda there, standing at the kitchen counter, with all manner of foodstuffs spread out around her and an open cookbook on the kitchen table.
"Hi, guys," Brenda said brightly. "Have a good time this afternoon?"
"Ah...yeah..." Jason replied. He found it a little disconcerting to have Brenda be aware of what he and her mother were doing, even though she clearly didn't mind.
"We had a nice time, dear," Karen said. "What on earth are you doing?"
"What does it look like, I'm making dinner," Brenda replied. "We got done early at the stable, so I came home and decided to cook."
"Well, that's a change," her mother said. "How's it going?"
Brenda shrugged. "I think I've gotten everything in that it says I'm supposed to put in here in the cook book," she replied. "I'm making a casserole. It's done. I was just about to put it in the oven." She smiled at them. "Everything else is all set, too, even the dessert."
"Honey, what's come over you?" Karen asked with a surprised look on her face and a startled tone in her voice.
Brenda blushed a little and shrugged. "Jeez, Mom," she said, "just because I try and cook once, you have to act like it's the end of the world."
Her mother gave her a big hug and said, "I'm sorry if I'm embarrassing you, honey. I'm pleased, I really am."
"Oh, by the way, Sylvia called and said she was going someplace with Paul and probably wouldn't be home until late," Brenda said.
While the casserole was cooking, they played several games of cards. Jason kept thinking about what Sylvia's mother had said during their time at the pool and wasn't really concentrating, which meant Brenda won all the games they played.
"What's up, Jason?" she asked while they were putting the food out on the table. "I can't believe you lost every game we played. What's going on, you trying to get on my good side or something?"
"No, that's not it," Jason replied. "I was just thinking about things."
They sat down and ate and, much to the surprise of Jason and Karen, the meal Brenda had cooked was quite good. Both of them said so, which caused Brenda to blush again.
"Well, since you guys are so grateful," she said, "you can do the dishes. I've got to be at the stable early tomorrow, so I'm going to bed early." She turned and headed upstairs.
"Jason, I'm sorry if what I said this afternoon upset you," Karen said as they cleaned up the dishes. "But I really do think it's important that those topics be out in the open. My darling, you really do need to face reality about this."
"What if I don't want to?" he asked. He knew he sounded petulant, but he couldn't help himself.
"Jason, you have to face the fact that what I said this afternoon is the truth," Karen said. "Heaven knows, I wish there was some way it could be different, but...well, there isn't."
"Yeah, I guess you're right," Jason said reluctantly. "I mean, I'm not that stupid. I just wish it didn't have to be that way."
"I know you do, my darling," Karen replied, touching him lightly on the hand. "Believe me, I wish it didn't have to be that way, either."
Once the dishes were done, they headed upstairs. As Jason took off his clothes and got into bed, he found himself wondering, for the first time since the night he arrived, whether or not Sylvia's mother would be joining him. He lay there, wide awake and scared, hoping that she hadn't decided to end their affair now. It was bad enough that he had to consider the possibility of it ending once he got home. If she stopped coming to him now...
He quickly learned that he didn't have to worry. Not long after he got in bed, the bedroom door opened and Karen, wearing a fluffy pink bathrobe, walked into his room. She closed the door behind her and, as she walked across the room, shed her robe. When she reached the bed, she yanked the covers back and, before Jason could move, she fell on top of him and grabbed his partially hard penis in her hand.
Jason wasn't sure what was going on. Karen was acting different, more like she had the first night she'd come to his room. She slid down on him and began to kiss his belly while she stroked his penis, making it rapidly swell and stiffen. An explosion of delight lit up his mind when she mother took his now-hard penis in her mouth and began working on him feverishly with her lips and tongue. While her mouth was busy, her hands rolled his balls and stroked his legs, making him get even harder and want her even more.
Just when Jason was afraid he'd come in Karen's mouth, she slid up so she was sitting astride his hips. She placed the tip of his erection between her vaginal lips, then she began lowering herself onto his swollen organ. A sigh escaped from her when he began to slide into her. "Oh, darling, yes!" she murmured, and began to move her hips actively.
Jason, still not sure what was going on, decided it didn't matter right then. He grabbed Karen's hips and began lifting his hips up off the bed, shoving himself into her. He could feel her snug, rippling inner walls clutching his penis as it slid in and out of her.
"Oh! Oh! Oh!" Karen groaned as Jason's erection pistoned into her. "Yes! Uh-huh! Uh-huh! Uh-huh!"
Jason continued to hold her hips and shove his hips up against her. He watched her breasts bob and jiggle in response to the frantic movements of their joined bodies. Then he felt the rippling of her vaginal walls grow more intense and felt her stiffen and knew she was coming.
