How many movies have Batten Kyushu Man and Saeko Matsushita collaborated on?

They have worked on 2 movies together! Their first movie together was BF-534 When I met my plain sister for the first time in a while, she had become so erotic that we had sex to make babies! (2018) and was their highest rated movie together. They have not worked together since A Full Course of Whore Sensuality Saeko Matsushita (2018).
