Well, he certainly lucked out! Not only does he get to split the cost of the room, get a free top-of-the-line dinner on the house, and get lucky with two foreign babes? Truly, luck that only a Hentai Protagonist could have.
Also, him worrying about what would happen after he told them they had to take of their towels was interesting. I suppose it's normal to worry about those things, but in Hentai, of course it's just their way of 'thanking' you for accepting the arrangement!
Great ending though. Well hey, I'm sure that's a way better arrangement than walking around!
