Souin Ningyou ~Oshiego to no Inkou~

Main character used to direct AV films, but was overwhelmed with this industry and quit. But as he runs out of money, he returns to the idea of filming such movie again with a weak-willed actress. He organizes brainwashing seminars and tracks down suitable candidate for actress at a certain school. After infiltrating the school he is severely questioned by female teacher there. Luckily, he happens to have teacher's naughty photo from past life, so he intimidates both girls into shooting as shameless actresses.
