On the first day of a new job as
a tutor, Issei finds the mother
of his student to be the woman he
had a fling with in Bali! Happy
to meet him again, she later introduces
him to her two beautiful "hitozuma"
(married) friends, lovely ladies
of leisure who are frustrated with
their boring sex lives. Before he
knows it, he agrees to become their
trainer in the pleasures of life.
Even though he feels a bit guilty,
he can't complain; he's having the
time of his life with these three
beautiful women! And he never wants
it to end...
