A female researcher named Misuzu works at a pharmaceutical company and has a secret fetish for swallowing cum! During her college days, she used to compare cum samples with her classmates just out of curiosity. She joined this project because she wanted to know what it feels like to drink professional men's cum and if it would make her horny. Wearing her white coat and gloves, she eagerly studies cocks while giving them blowjobs and handjobs. When they cum, she greedily swallows every drop with a smile on her face. Her sensitive body reaches climax easily even by just touching.
