Aiko works for a pharmaceutical company and spends her days in a science lab. She comes to a porn audition asking a male porn performer to help her research what happens inside her vagina. Looking serious in her white coat and glasses, she pauses during fingering and raw penetration to take notes whenever she notices something useful. Will sex in the car give her any new insights? The experiment ends with a heavy creampie—and she looks surprisingly cute when she takes off her glasses.
