The director Aoi Rena is a genius! She invited three popular AV actresses under the pretense of consulting about premature ejaculation for early-release M-boys, and requested them to indulge in semen-draining activities under the guise of premature ejaculation improvement training. From four men who gathered without knowing anything, she extracted a total of 15 ejaculations! Various techniques of perverted women can be seen, including handjobs, blowjobs, anal torment, and creampie sex!
