Payback (with panties!)

Your friend Richard invited you to spend the weekend with him at his family's cabin. (though you were never sure why they called it a cabin; it just looks like a house in the woods) Anyway, Richard's pretty fun. You feel a little guilty about certain rumors you started around school earlier in the year about his "tiny" penis in hopes of deterring Mandy Fisher (who you liked at the time) from hooking up with him, but luckily he never found out it was you, so you're still pretty good friends.

Unfortunately, on the hike there, a spontaneous dip in the river ended in your bag of clothes apparently being swept down the river while you splashed around in blissful ignorance. Now as you stand soaked and shivering behind the "cabin," Richard brings out a big box of old clothes his family had left packed away somewhere inside. He plops the old cardboard box down on the picnic table in front of you, and apologizes, "Sorry man, that's all the clothes I could find. You can change out here, nobody can see you. Just hang your wet stuff on the clothes line." He walks back toward the house.

As soon as you open the box flaps and begin to rummage through the contents, eager to get into something dry, you realize that all the clothes in this box belonged to Richard's sister.
