Back at the cabin, Ted was embarrassed. After his sister had seduced him and given him that hand job, he found it difficult to even look at her. But he had to try and act normal so his parents didn't suspect anything. Their week at the lake was just beginning.
For her part, Abby didn't act like anything had happened. She was just as bouncy and vivacious as ever. It wasn't too long before she was making Ted feel more normal as well. By bedtime Ted was overwhelmed with thoughts. Why did she do that? Would it happen again? Would more happen? Should he let it happen? Was he silly for even thinking that it could happen again? These and many more thoughts whirled through his mind as he used the bathroom then entered the room they would be sharing.
"Are you okay, little brother?" she asked Ted.
He looked at her sweet innocent face. "Yeah, I guess so. This morning was amazing, though."
She smiled at him. "Good. I enjoyed it, too. You have a beautiful penis."
Ted laughed nervously. "You are really blunt. I'm not used to that."
Well, I'm used to guys, and sex, and..." she paused, reaching over to put a hand on his leg as he sat on the bed opposite her, "and penises." She smiled at him.
He smiled back, amazed at her frankness. "But you are my sister," he reminded her.
She looked deeply into his eyes. "Ted, I had a couple of friends - you know, Sissy and Cathy, in particular - that had gorgeous brothers. I often wondered how they lived in the same houses without screwing their brains out. But somehow - somehow - I overlooked the hunk that was living with me the whole time."
Ted blushed when she called him a 'hunk'. But his mind reeled at the thought of her screwing his brains out. But screwing was a long way from a simple hand job. He was very happy with that, and was wondering if he would get another. The way she was talking, he might. And it didn't even cross his mind to think if he would let her or not.
Abby giggled while he thought, and when he looked where she was looking he knew why. He had gotten an erection during their talk, and it stuck up prominently in his boxers.
Abby moved her hand slightly, pulling at the material, and his stiff rod popped out of the fly, waving in the air.
"Yeah!" Abby said, though it was nearly a whisper as their parents were in the next room. "That is so nice."
She stared at the thick rod pointing up from his pants. She couldn't see the whole thing, but knew it was about eight inches in length and just about the thickest that she had seen.
"Lift up," she said. She held the material on each leg between her fingers, and as he lifted off the bed she pulled them down to his knees. His dick was pulled down and slapped against his stomach as it was freed. She continued pulling them down his legs to the floor, staring the whole time at his erection in front of her face.
She put her hands on his knees and started sliding them upwards. Sliding between his legs on the way, she forced his legs apart. He jumped when her hands bumped into his balls. She bounced and squeezed them. The base of his dick was encircled by her hands, then they began a slow ascent up the entire length of his dick. Ted was having trouble breathing.
