Monday morning the family had a big breakfast. Abby's thoughts were almost all about sex. Looking at her grandparents, thinking of what she had witnessed, she had a new respect for them. And also she had an aching in her loins that signaled a need for cock. Her pussy had felt empty all night after watching that show, and today it still felt empty. When she looked at her brother she saw only the solution to her problem. Of course, since the first day here she knew she would be seducing him, but now she determined that it would be today.
Not long after her grandparents left, Abby announced that she and Ted were going to take a hike in the woods, or maybe take the boat out. They needed some exercise after the day with the grandparents, which had not been a very physical day. Abby smiled at the thought that they had quite a physical night, though.
She and Ted took off for a hike. It was possible to go for miles through the woods and up and down the hills without seeing another person. That was true in the summer, but now in the Fall, with much fewer people around, it was even more so. But they hadn't walked very far until Abby started sharing what she had seen with Ted.
"I went for a little walk last night when I couldn't get to sleep," she began.
"Yeah," said Ted. "I heard you go out, but must have fallen asleep before you got back."
"You wouldn't have fallen asleep so quickly if you had seen what I saw," she teased.
Ted looked quizzically at her, and she continued. "Did you know that our grandparents still have sex?"
Ted still looked the same. "I suppose they could. I really never thought about it."
"Me either," Abby said. "Until I saw them doing it!"
"WHAT?" Ted stopped dead in his tracks and stared at Abby.
"Honest to God, I did," she said. "Last night."
"You watched?" Ted was trying to process what she was saying, but was having trouble.
"Well, I didn't mean to," she said defensively. "They sleep with their TV on all night, and it puts out a lot of light when it's pitch black..."
"And you just happened to be walking by?" Ted interrupted.
"Yes," she answered. "Exactly. I was walking around the cabin and saw the light coming from their room. I saw them cuddling, then all of a sudden they were naked, and she was jacking him off..."
"WHAT?" Ted again asked.
"And she crawled on top of him and fucked him, you know, cowgirl style."
"Oh my God!" Ted mumbled.
"And he came, deep inside her while she was on top. and then, when she rolled off, he finger fucked her until she begged for mercy." Abby enjoyed watching Ted wince at the words and the visuals.
"It was really quite sexy," she continued. "After they were done I had to masturbate outside in the dark before I could come in."
She smiled at Ted, who was just staring at her. His initial shock was gone, but he was still processing.
"He finger fucked her?" Ted asked.
"Oh, don't say that. Just hearing those words is making my pussy hot again." Abby used his comment to try and change the subject to her. She was hoping he would get interested in her.
And she was right. Ted's thoughts now shifted from his grandparents to his sexy sister right in front of him. She looked amazing, and she didn't seem to have many inhibitions. She used blunt language, and she did seduce him a couple days ago. He wondered if she was still excited enough about what she had seen that she might be willing to stroke his cock again. Maybe even another blow job. He was getting excited at the possibility.
Abby noticed the bulge in his pants, and when she had mentioned her pussy it got larger, She thought her little brother wouldn't mind a repeat of the other day. And more, she hoped.
"Look at that," Abby said as she stepped closer to him. "What has your dick getting all hard? Is that for your grandparents or for me?" she said with a laugh, while one finger traced the outline of his erection.
"Ah, for you," he answered. She really hadn't given him much choice. The truth is, he had started to get hard during the story of their grandparents. Well, it was the story - the sex - not the grandparents that made him hard. But then she mentioned her pussy!
Ted was unsure of himself as his sister rubbed his dick. He wanted to rip his pants off and let her play with his naked cock, but if he was too aggressive he might freak her out. The last thing he wanted to do was scare her away, so he let her set the pace. He just hoped she didn't take too long.
Abby looked at him with innocent puppy dog eyes and asked, "Do you mind if I do this?"
"No, I love it," Ted answered.
She lightly stroked his shaft a few times, Then with one downstroke she kept going after reaching the base of his shaft. She continued down, holding nothing but the fabric of his warm-ups, which pulled the elastic waistband down a bit.
"Whoops." she said, with those same eyes.
Ted just smiled back at her. He reached for his waistband and pulled it down to the widest part of his hips. Just helping, hoping she would continue. He really wanted his dick swinging in the air between them, her grabbing hold of it. He nearly ached.
Abby loved what he did. She thought he was a little shy, a bit tentative, unsure what to do. But he seemed willing. That was all she cared about. She pulled his pants over his hips, down his legs, and his boxers went with them. He stood there, his naked dick waving at her face. She did not touch it with her hands. She leaned in and captured the head between her lips as she heard a loud sigh escape from Ted's lips.
