You figure that getting your groceries now is the best option, given that your roommate is expecting you to return with food for the week. You pop open the packaging and slide the glasses into your collar, figuring that you can see what these can do outside of the trial packing.
Walking into the grocery store, you force yourself to just do your shopping until you get a good opportunity to look at only one person through the glasses.
Most of the other shoppers are either in groups or in positions where it would be hard to avoid other people in the aisle. You make it through about half of your list before coming upon a young man comparing two packs of hotdogs. Alone. This is your chance.
He has his back to you as you stand by a cooler, pretending to look at the frozen fish on sale. Casually sliding the safety glasses over your eyes, you see in the man's place a skunk woman, just like earlier in the parking lot. Her fluffy tail conceals much of her body from your spot behind her, but you can clearly see her shapely ass and legs. Peeking over the glasses, you are shocked to see her still there. Well not so much that she's still there as the fact that she is still a skunk.
Quickly taking the glasses off so as to not accidentally change any more people, you continue staring at the woman for a moment before coming back to your senses. Walking up to the girl, you reach across to the hotdogs and say a quick "excuse me" to get her attention.
"Oh! Sorry boss, must have spaced out for a second there." She said, seemingly recognizing you. Now face to muzzle, you finally get a good look at her. She is fairly slim, with modest breasts covered by the white fur along her stomach and torso. Her face held an oddly human expression of giddy excitement and she was bouncing in place slightly, causing her breasts and tail to bounce. "I got my half of the groceries, so if you're ready we can head to the checkouts."
Sure enough, her cart is full of groceries from the other side of the store. It's a bit more than you usually buy, and a glance at the cart you're pushing shows that extra veggies and deli meat had appeared. Checking your phone as the skunk leads the way to the front of the store, you find a new contact with quite the text history between the two of you. From this info you gather that her name is Lillie and that she lives with you.
By this time you have made it to the cashier and Lillie was unloading her cart onto the conveyor. The cashier pays no mind to Lillie's current skunky appearance, and hands you the receipt with a "Have a nice day!"
On the walk through the parking lot, you glance back to the magic shop. The store is still tucked away to the side of the strip mall, and you don't see anyone entering or exiting the shop. You take the time to really examine the Stink'TY GLASSES, pulling them out from your shirt collar as you trudge to your car. For the first time, you notice several small dials on the arms of the glasses, near the temples. These are marked only with an arrow notch meant to signify what position it is in. Testing the forward right dial shows that it clicks into place three times, and was originally in the middle position. The other three dials seem to have four clicks, all currently at what you decide to call "1 position," the final setting of a counter-clockwise turn.
A soft /pfft/ brings you from your thoughts just as a whiff of skunk spray hits your nose. You see Lillie has fallen in line with you and she shrugs at you when she has your attention.
"I knew that would wake you up. Been holding it in for a while there. Plus, we walked past the car." She pointed back at your old sedan where she had left her cart.
"Heh, yeah. Sorry." You quickly backtrack to the car and unlock the trunk. The two of you quickly load all of the groceries into the trunk and the frozen food into the cooler you keep in the back.
You're still hungry and think fast food sounds good, but you could just go straight home and eat there.
