We’d been out exploring when we found what looked like a cave at the bottom of a natural pit in the rocks. I went down first, but then instead of following, he pulled the ropes back up as soon as I let go of them.

We’d been out exploring when we found what looked like a cave at the bottom of a natural pit in the rocks.  I went down first, but then instead of following, he pulled the ropes back up as soon as I let go of them.  

What I can’t figure out is how serious he is about not getting me out until I put on the chastity belt he dropped in.  He knows I’m not gay and I didn’t think he was either, though now I’m starting to suspect I might’ve misjudged that.

It’s probably just the start of a particularly intense prank war.  I mean, the weekend will be over in a few hours, and he knows I need to be back at work tomorrow.  He’ll give up by then, right?
