Etch, who's just two in a narrow place, proves to be pretty erotic.

I don't like etching at close distances. There are many places where you can be alone with a woman in a narrow place, right? It’s kind of awkward, but it also has a unique erotic atmosphere. People are sexually conscious when they get close to each other. such spaces, closets, elevators, cars, saunas, baths, toilets... There is plenty of mating between men and women who are greedy at a distance to breathe and smell.
