I bought this years ago and it's brilliant!

Good to hear, man. Thanks.

I think the magic of this scene is the fact that Akane was actually having a bit of an awakening during the shoot. She was an old friend who was in town for the day and was really curious and interested to shoot stuff for my "new" (at the time) site. We started the day at a restaurant where I had her take her shoes & socks off under the table while I quietly shot it; and that got her a little bit excited because it was low-level naughty - at least it was for someone who'd always behaved in a reserved way and followed the expectations of Japanese society.

Then we went back to the apartment and shot a messy foot video where she gave a simulated footjob. But she'd never even heard of a foot fetish before I told her about it, so she was fascinated by what I was asking her to do and the fact that I found it quite hot. And that ramped her own excitement up a tiny bit.

But when I started pieing her in the face and covering her with slime in the next scene, (she told me) she found herself seriously aroused by it. So, after showering off, she was really eager to get pied and slimed more in the last scene, which was this one, "The English Quiz." So, I think you and I probably perceive the same thing when we watch this scene: the model being pied is sexually excited by it - and that's fucking hot.

Plus, I don't know if her feet are an important factor for you, but as a foot fan I put Akane near the top of my list of models I've worked with who have goddamn sexy-as-fuck feet. (Other Pied Asian Girls models whose feet I'll never forget include Yuko, Sayaka, Yuri, Mercury, Sora, Maki, Kyo, Linda, and of course, my wife, Chika!)
