It's....Another sock...(and a mask?)

Unrolling the small piece of fabric to no surprise (but great disappointment) the next article of clothing "gifted" to Mackenzie was yet another knee-high sock. The otherwise naked redhead slid the matching sock onto her other bare foot, both her feet and lower legs somewhat protected from the elements. The feeling of pavement on her soles through the thin cloth felt more taboo than when it was just her bare feet. Somehow with +1 article of clothing Mackenzie was feeling more naked than before...

The sound of a passing car snapped Mackenzie back to reality, causing her to press her naked body further into the side of her house as if attempting to disappear entirely.
"T-this is so stupid..." Mackenzie lamented, unfolding the note in her hand. Unlike before the message this time wasn't written on a single piece of paper but a series of three small bright pink post-it notes, and appeared hastily written. "Heh, your getting sloppy" Mackenzie smirked at the thought of her 'fan' trying to keep up with how fast she was doing their tasks. "Bring it on creep. what's your challenge this time?"

Bravo, I wasn't expecting you to accept and do the challenge so fast! You're more daring than I originally thought. So how about something a bit more BOLD this time?

As you've noticed you now have coverings for your feet so how about next we go for a little walk? I hear the nearby park is nice on days like today.

H-he had to be joking... the park, though pretty wooded and concealed was three blocks away through completely exposed streets. Everyone would see and recognize... wait. there was one last note.

Since I'm so generous I've also chose to include a covering for your identity as well. Don't say I never do anything for you. Put it on if you accept my challenge.
-A Fan

"A covering for my identity?" Mackenzie whispered to herself puzzled. There was nothing else in the mailbox. It's then that the breeze from the dancing drone peaked the nude redheads attention. Dangling off the bottom of one of the drone's landing struts was a small piece of cloth. **** for any new piece of wear mackenzie snatched the cloth from the drone almost sending the small machine careening out of control. "S-sorry..." Mackenzie winced remembering that if she broke the drone the 'game' would end then and there.

Looking down at the small ovoid cloth in her hand Mackenzie's heart sunk as it wasn't anything she could use to cover herself any more with. Well, not anything important at least. It was a mask. a small black mask like the one Zorro would wear (and it matched her socks too...)

"[...]Put it on if you accept my challenge"

Surely this next task would be taking it too far...
