One of the many varieties of brothel
s in Japan
. Image clubs specialize in satisfying fetish
es, i.e. the customer pays lots of money for a girl dressed up in a costume that turns him on to perform sexual act
s on him (or let him perform such acts on her). Surprisingly, actual vaginal intercourse
is usually not offered; most girls won't go further than giving blow job
Anyway, "perform" is the key word, since acting the role is probably the most important thing. The most popular fetishes by far are schoolgirl and nurse; others are various anime characters and uniform-wearing professions.
