MIDV-437 I hate the professor in my lab who sexually harasses people, but he's incredibly compatible and has a massive dick... ~The science girl falls into forced sex after being cuckolded in a shared room~ Miyu Oguri

Miyu is a sullen female college student who has little sexual experience, but actually fantasizes that she wants to be fucked by a man with a big cock. She's a serious type of boyfriend like herself.Although she has Makoto, she wasn't satisfied at all with sex with him. One day, at the suggestion of Professor Oshima, she went to a research camp with her boyfriend and her alumni. She hated Oshima, who has a high-pressure and sticky personality, but at her training camp, she was forced to share a room with her big cock and skilled erotic technology.
