A self-employed couple, exhausted from life and work and unable to enjoy a proper sex life, visited a psychosomatic clinic. Waiting for them was a corrupt doctor named Ozawa, who, under the guise of treatment, subjected them to lewd brainwashing and sex training. In that horrifying clinic, a vile medical practice that dug into the cracks of their hearts began. The wife, Miki, gradually transformed into a lewd woman, craving Doctor Ozawa's extra-thick dick and taking it deep into her throat. Ignoring her husband's shocked protests as he secretly watched, she went on to perform an M-legged spread dildo masturbation and then fellatio in front of Doctor Ozawa. To the protesting husband, Ozawa coldly declared, "Miki-san is starting to awaken to real sex—it's time you woke up too! Now, go ahead and have sex with each other right there—real sex!" Contrary to the husband's joy that everything had gone well, Miki still couldn't forget Doctor Ozawa's extra-thick dick.
The gradual feeling of falling is good. From the stage before reaching the sex scene, her acting ability to gradually shift into a lewd expression stands out. Because this change is carefully depicted, you can thoroughly enjoy the process of her descent into depravity, and you're constantly kept on edge with anticipation. And when the sex scenes unfold without betraying that expectation, the excitement you get is exceptional. It was truly a wonderful work.
