Mom Clothes → Step-Sister's Skimpy Microskirt

I think maybe... it'd be pretty hot if I enhance Mom's cosplay a bit by making her a little more tropey. So, let's exaggerate it a bit by replacing the clearly inaccurate phrase 'Mom-Clothes' with something more suitable for the type of character she's playing, like 'Step-Sister's Skimpy Microskirt' ---

I stifle a grunt as the sensation of my raging woody decides now's a good time to remind myself of it. I don't know how I'd forgotten just how hard I was, given I'm recording a skit for Penny. Today's flavor is 'school-girl puts on a magic collar, starts to think she's a dog and gets frisky with her step-brother,' which is... just about as unsubtle as I'd expect from the half-sibling I share a room with.

Penny's really gotten a bit of a 'thing' about that kind of stuff, ever since I made the "best" mistake of my life and showed her an anime that had things get just a little spicier than normal between the siblings. Apparently it was some kind of signal flag to her, because now she's doing her level-best to act out and fill every role to that nature she can think of and, um...

Well, I'm not really against it but people'd certainly still find it weird if our dynamic came out in public, so it's a careful balancing act. At least Penny only uses the recordings for personal use and doesn't share them online... but given the college we're attending that's only a matter of time, isn't it?

Anyway, I digress. I can't really get a good view of Penny's skirt from here, but I'm sure it's certainly shorter. She'd be happy about that, I suppose: Getting this kind of apparel without having to deal with the strange looks is worth a bit of **** of real magic, right? "Of course!" Is what she'd say in a heartbeat, if she were being honest and not taking the opportunity to tease me by playing faux-offended.

...Honestly, it's kind of terrifying to imagine what Penny would do to me if our positions were reversed. Good thing I've got the power here. So, how to use it...?
