Last night at the party, a dead drunk you stripped down your panties on the spot, saying you're going to the washroom.

Good thing that I stopped you, but then you were gone leaving your underwear behind.

And later I found them while cleaning up the mess after the party.

Since it was really late at night, I decided to keep them 'til morning.

...Well, I honestly didn't think you'd just stay like that until now, though.

Here you go.

That was some nice gift for my promotion.
