"What are you doing in my suitcase?" Lydia asked.
Danny sat next to the bag, Lydia's red thong in his hand.
"Oh, fuck. I'm sorry," he blushed. "I just wanted to look."
Lydia laughed. "My little brother, now in his 18th year as a pervert," she said.
"Shut up," Danny said.
"You're so busted."
They hadn't played since the day Danny arrived home for Christmas break; he too busy helping their father get the old Chevy back on the road, and she always off somewhere with her best friend Alice. But he couldn't get the image out of his mind: Lydia standing at the bathroom mirror, her white panties hugging her ass, full breasts shaking as she tried to cover up.
He didn't mean to walk in on her that morning and he certainly didn't intend to touch her, but that innocent hug hello had led to other things. Or maybe it wasn't innocent. Maybe Lydia planned it. Maybe she wanted to fuck him. He couldn't figure it out.
And he couldn't resolve his feelings of guilt, shame, and arousal. Every night when he laid down to sleep, he could see Lydia's breasts shaking beneath his thrusts, hear her moans, feel her hands on his ass, her breath on his neck. He could smell her. Danny knew it was wrong, but he wanted her again. Maybe it was better that fixing up the Chevy kept him busy.
"So what were you going to do with those?" Lydia asked.
"Seriously, I was just looking," he said.
"Well, Alice is coming over any minute and I don't think you want to stand up when she gets here."
"Shut up," Danny said. He dropped the panties back into Lydia's suitcase. He stood, and his erection bent down his pant leg. He adjusted himself, and Lydia laughed. He hurried out of her room and closed the door behind him.
"Have fun," she shouted.

Danny lay on his bed. Sixty pages into his required reading for next semester he realized that he hadn't retained a single word. An hour wasted, his head swimming, buzzing with sex. He closed his eyes and inhaled deeply, trying to conjure the smell of his sister's red thong. His cock throbbed against his jeans. He unbuttoned them, and there was a knock on the door.
"Yeah?" he said, and he set the open textbook on his lap.
Lydia opened the door. "Hey, can you come help me with something?" she asked.
"Sure, just give me a second." He changed into a button down shirt with a long tail and left it untucked, then he walked down the hall to his sister's room.
"What's up?" he said.
"Hi, Danny."
"Oh, hey Alice. What do you need help with, Lydia?"
"We were just talking about games," Lydia said. "Alice was talking about how boring it was growing up an only child and having nobody to play with, and I was telling her how much fun it was having a little brother."
"Yeah, I guess," Danny said.
"But I told her that even when there's only two of you games are pretty boring. Remember all those times we played Monopoly and Risk? They kind of suck with two people."
"Sorry...Clue..." Danny added. "Battleship was okay."
"I hated Battleship. You always lined your boats up," Lydia said. "Anyway, I think we should make Alice our honorary sister."
Danny laughed. "Yeah, sure. Whatever. Want me to go pick out a game, sis?" he asked Alice.
"Whatever you guys want to do," Alice said, and she smiled. Danny liked her smile. The air in the room was thick, heavy. Nobody spoke.
"If I'm going to have a sister, I'm not playing fucking Monopoly," Lydia finally said. "I'm going to play girl games. Let's have a fashion show. Danny can be the judge."
"You're joking, right?" Danny said.
Alice laughed. "I think it might be fun," she said.
"Okay, here's the rules," Lydia said. "Danny, you have to keep your eyes closed until we're ready. Alice, we pick out each other's outfits."
