A male actor infiltrates a dental clinic and devises various erotic strategies to make the beautiful dental assistants give him blowjobs. Among them, the "penis-bulge tactic"—emphasizing the size of his crotch—proves highly effective, drawing the assistants' gazes directly to his groin. In particular, one sexy assistant who looks just like Akiko Yada can't resist reaching out when she's stared at. Despite being in the middle of treatment, stimulated by the actor's erotic techniques, she writhes her body and moans passionately, resembling a scene from a movie. The burning desire barely concealed beneath their masks deeply stirs their hearts.
