This was one of those scenes that made me go "...Huh. That's a fetish I didn't know I had."
I'm never sure whether to be grateful or annoyed when that happens. Sure, new kinks are fun and eye-opening. But they're such a hassle, too. I mean, you have to Google all new porn, with all the risks and headaches that entails, and possibly reorganize your smut folder. Then there's the real life dilemmas which may arise, such as, say, figuring out the minimum discreet distance from which to follow and ogle that attractive goth-loli catboy maid at the anime con and what you'll say if his girlfriend turns around and catches you. It's such a chore.
