After Scott went back to campus, he kept revisiting the sight of his sister shaking her ass. He went online to look at videos of young women twerking, but every woman turned into Tiffany. On Thursday evening, he called her on her cell phone. He tried to hide the reason he was calling. "So, did your dance work on Jimmy?" he asked.
"No," she answered sadly. "We were in his room Tuesday night. I told him I wanted to show him something. I went to YouTube on his laptop and called up the song you walked in on. I think he liked the way I was looking at him over my shoulder, but as soon as I bent over and he could see my thong, he stopped the video. I asked him what was wrong with him, and he said, 'Nothing. What's wrong with you?' and he pulled my shirt back down over my thighs. I was mad and humiliated all at the same time. I left his house and haven't talked to him since."
"Good," Scott told her. "You deserve better than that." He meant what he said, but he hoped she couldn't tell the real reason he was happy to hear about the outcome. "Wait, you had a thong on? When I walked in on you, your butt was naked."
"I wore the thong 'cause it's sexy, and I wanted him to enjoy himself when he took it off. I didn't wear it when I practiced because I just wanted to get comfortable learning the moves."
"Anyway, I'm coming home the weekend after this one. Remember what we talked about?"
"Yeah," Tiffany said with a smile. She thought, "It's all I've been thinking about since I left Jimmy's place," but she managed not to say it out loud.
"I know an under-21 club where they play that kind of music. It's about a half-hour west of our house, so no one'll know who we are."
"Great! We can meet up at the city library and take your car from there."
On Monday, Scott called their mom and told her he'd be coming home that weekend. All through the week, he remembered his sister's sexy ass and the brief view he'd had of her pussy. On Friday night, he was seated across from her at dinner and was dying to see both those parts up close again. Tiffany helped him a little by making a point to carry things to and from the table, giving him multiple opportunities to see the shape of her ass, if not the flesh.
At breakfast on Saturday, she was wearing a long T-shirt that showed off all her curves but didn't reveal any of the flesh that he dreamed about. It drove him crazy that she was right there and he couldn't tell her how sexy she was. After breakfast, he said the guys from his floor in the dorm were going on a float trip next weekend, so he needed to put his sleeping bag in his car. Once he'd put it in his trunk, he drove off and called Tiffany. With no one else knowing who was calling her, he told her not only how sexy she was but what he wanted to do to her that night. He also saw that gasoline cost a dime less around home than at school, so he filled his tank and used that as the reason he'd taken off.
Tiffany wore short shorts and a tank top for the rest of the afternoon. She was trying to tease Scott, but she ended up torturing herself as well, thinking how his hands felt on her ass. He texted her and apologized for not having anything that would do the same thing for her that she was doing for him. She replied, "I could see ur tongue, & ur jeans r tight enough! :)" Scott changed into a silk shirt but kept the same jeans on. Tiffany put on the same top she'd worn when Scott walked in on her, but she wore an even shorter skirt. She left ten minutes earlier than Scott and met him at the library. On the drive to the club, Scott toed the line between watching the road when the car was in motion and trying to get an eyeful when he looked down at her chest. For her part, Tiffany put her hand on his knee and occasionally rubbed close to his crotch, but never touched his dick. Neither of them said a word for fear that he'd lose control.
Once they were at the club, they opened up. Scott admitted that he'd been thinking about the night since he got home the last time, but didn't say anything about watching other women. Tiffany confirmed that she had broken up with Jimmy, but she didn't actually have the conversation with him until the day after Scott called. Scott finally asked, "Did you really like it when we fooled around, or was it just because it's forbidden?"
"Both," Tiffany answered. "You reacted exactly how I hoped Jimmy would."
Scott whispered in her ear, "You mean you wanted him to come inside you?"
"Hell, yeah, but I liked it better when you did."
They talked about other things, and then told her, "After watching you, I decided to look at more videos of women doing the same thing. I noticed that a lot of the songs mention making babies."
"I noticed that too," Tiffany said.
"You realize that was a risk, don't you?"
"Oh, yeah, I knew."
"I kinda figured you did when you told me point-blank, 'Come in your sister's cunt!' You even mentioned my seed. So, when you thought about it afterward, did you panic?"
"No, it turned me on even more!"
Hearing that, Scott pulled Tiffany to him. He gave her a deep kiss and rubbed her butt. She ground her hips into his. She expected to feel how hard he was, but he was pressed so deep into her flesh that she was even reminded of how thick he was. "God, I can't wait to fuck you," he whispered.
