Chapter 2

“Morning,” Caitlin said, and Brad opened his eyes to find her staring down at him, a smug look on her face. “Looks like someone had a good night.”

Glancing down, Brad could see that he was still in the same clothes he’d fallen asleep in, the underwear he’d jerked off in and nothing else.

Except ... were they? He was intimately familiar with his sister and mother’s underwear collection, but paid far less attention to his own. He didn’t even recognize his own underpants. They felt different too - tighter, a bette fit.

“Oh god,” he said groggily, still too hazy to even question his sister’s presence in his room. “I don’t even remember going to sleep last night.”

With a glance over at his desk, Caitlin nodded towards the pen he’d been making notes with.

“Found the gift I left you?”

“What?”

“Your pen. I sweetened it for you.”

Brad wrinkled his nose in confusion. If his sister’s plan was just to confuse him, it was certainly working. Her whole attitude had changed ... and, now that he looked closer, so had her choice of clothing.

Caitlin normally slept in a nightie - once upon a time, her choices had been more revealing, but as he’d slowly given up on masking his lustful gaze, she’d responded by wearing clothes that covered up more and more of her flesh.

Nothing as much as this, however. She was dressed in slacks and a sweatshirt, an outfit he’d never, ever seen her in. It exposed less skin than anything he ever remembered seeing her wear, and - even more strangely - it looked like it was covered in grease and sweat-stains.

No. He must still be dreaming.

“Take off your top,” he said. If he was dreaming, she’d do it, and if he wasn’t ... well, what was the worst that could happen?

“Sure,” she said in surprise, then paused to collect herself. “Soon as you show me what you’re packing under those briefs.”

Bradley hesitated, and memories of their encounter yesterday started coming back to him. She’d been trying to tempt him into embarrassing himself then, as well, but this ... this felt different.

He couldn’t see a camera on her person anywhere, and while she could have hidden one in his room before coming in, it seemed risky, and he wasn’t sure what the payoff would be for her. What was she going to do, put pictures of his dick online? If that was her end-game, she could just do that next time he texted her a few shots.

For the next few moments, there was a silence between the two siblings as Bradley weighed up his options, and considered the risks. Finally, he nodded.

His sister’s reaction didn’t help alleviate his confusion at all - her eyes lit up, before being clouded by suspicion, and she tilted her head to the side.

“Really?” she said, and when he just nodded again, scoffed. “You slut.”

Brad had never been called a slut before, but if it was going to get his sister’s top off, he was more than happy to put up with her attempts at verbal abuse. Slowly he slid his briefs down. His dick had been hard already from the vague-but-erotic dreams he’d experienced the night before, but knowing that his sister was looking at it - wanted to look at it - had caused an erection as hard as steel.

He sat there, savoring the moment as Caitlin looked adoringly at his erection. He didn’t have a porn-star sized cock, but he’d always been pretty happy with it, and his sister’s reaction showed that she wasn’t disappointed.

“Your turn,” he said, and to his shock, Caitlin grinned, and immediately took off her top in response.

Under the baggy sweatshirt (which, he realized as she removed it, was probably her ex-boyfriend’s) she wasn’t wearing a bra, and Brad’s jaw dropped as his sister’s hefty tits came into view.

Unlike the times he’d peeked on her in the shower, this time they weren’t hidden behind glass and fog. Her smile widened at his expression, and just as she had the previous night, she pulled her shoulders back, pushing her boobs forward and arching her back.

Brad’s hands were itching to reach out and grab them, pull at her thick nipples and slap them, but he held back. For reasons he didn’t understand, his sister had just stripped in front of him, and he wasn’t going to do anything that risked this incredible sight being taken away.

“You like what you see?” Caitlin said mockingly, and Brad found himself unwillingly nodding, unable to take his eyes off the naked pair of tits in front of him. “You’re a fucking slut, aren’t you?”

He was about to say something in response (he wasn’t sure what, but something) when his mother stormed in.

Brad’s suspicion that it was a dream increased when her response to her two children exposing themselves to each other wasn’t anger or shock, but simple resignation.

Directed at Caitlin.

“Jesus Christ, girl,” she said with a frustrated sigh. “You have got to stop this. Leave your brother alone!”

Bradley almost opened his mouth to defend her, but immediately worked out what a poor plan that was. He had no idea why his mother had assumed this was Caitlin’s fault, but it was very much in his best interests to let her keep on assuming.

Instead of defending herself, his sister just rolled her eyes in response, and slovenly made her way out of the room, not even bothering to put her shirt back on.

As Brad watched his sister’s incredible tits leave, his mother turned to him, a look of concern in her eyes.

“Are you okay, sweetie?”

“Uh...”

Before he could formulate a thought, she continued.

“I’m sure she’ll grow out of it. She has to.”

He nodded in response, and his mother shook her head.
