Suggest she put some damn clothes on.

‘What? No,’ John stammered, closing his eyes again. ‘Come on, you’re my little sister. But you could at least, you know, put come clothes on.’

‘You want me to put clothes on?’ Louise asked, incredulous. ‘So you were looking at me.’

‘No, no, I…’ John sighed. ‘Please, I just need a ride to the doctor.’

He opened his eyes again when she didn’t respond, surprised to see she was slowly pushing the blanket even farther down her body with her feet, exposing her naked legs. ‘You need a ride to the doctor, do you?’ She rolled onto her knees and faced John .

‘Uh, yes, there’s something wrong. Please, Louise,’ he said, keeping his eyes past her shoulder. There was no way he’d let her catch him gawking again, even if she did have a gorgeous body.

‘John,’ Louise said, speaking as if she wasn’t barely clothed in front of her big brother. ‘You know I hate it when you rhyme my name like that.’

‘I’m sorry. Look, can you drive me? Please?’ John asked.

Louise ignored him. ‘If you weren’t checking me out,’ she began, moving closer to where he was leaning on the mattress, ‘then what colour are my panties?’

‘What?’ John mumbled, using everything he had not to glance in the direction of the clothing.

‘What. Colour.’ Louise moved closer and closer, spreading her knees further with each shuffle. ‘Are. My. Panties.’

‘I didn’t see your damn… panties, Louise.’

‘Oh? How about this then.’ On the corner of his eye, John swore he could see his little teenage sister carefully pulling the edge of her nighty up to reveal more of her thighs beneath. ‘You tell me what colour panties I’m wearing, and I’ll drive you to the doctor. That’s what you want, isn’t it?’

It still took everything in him not to simply glance down. It would be that easy. ‘What the fuck are you talking about? Why?’

‘Because I know you were checking me out, John. And I’m going to prove it. So, colour. Say it. And I’ll take you.’

John considered whether or not he was falling into some devious, teenage trap that would end up humiliating him more than he already felt, knowing Louise wasn’t above such an act. However, as another shot of pain emanated from his crotch, he knew he had to get to the doctor as soon as possible. If that was what it took, so be it.

‘Pink.’

Louise gasped in mock surprise. ‘Really? So… you were checking me out?’

John shook his head in frustration.

‘Why don’t you make sure?’ Louise said, looking down at her exposed thighs. ‘One little look. Then we can go.’

John sighed and knew getting to the doctor was more important than her plan for his humiliation. He quickly glanced down at her waist, where she had indeed pulled the hem of her nighty up, all the way to her belly button. A pair of lacy, pale pink panties clothed her teenage pussy, and her smooth thighs were spread almost horizontal below.

‘Okay. They’re pink,’ John said, looking back up as quickly as he’d looked down. ‘Can we… please go.’

Louise leaned over and planted a quick peck on his cheek. ‘Just let me get dressed.’

John left the room to allow her some privacy, trying to figure out what had just happened. The image of his little sister spreading her legs, her lacy underwear the only thing containing... He quickly stopped himself from continuing the thought, and as another pain shot through his crotch, Louise came from her room, having taken his suggestion and clothed herself a little more.

'Shall we?' she asked in a chipper tone.
