The professor from my hated lab turned out to have perfect compatibility and an incredibly huge dick... ~The science girl's descent into roommate NTR and drug-fueled sex~ Miyu Oguri
Miyu is a shy college girl with limited sexual experience, yet she secretly harbors a fantasy of being taken by a well-endowed man. Though she's in a serious relationship with her honest and sincere boyfriend Makoto, and even considering marriage, their sex life leaves her unsatisfied. She ends up joining a research retreat organized by her professor, Osajima—a man she dislikes for his domineering and persistent nature. At the retreat, she's unexpectedly forced into a shared room, where Osajima, packing a huge cock and skilled in erotic techniques, gradually overwhelms her resistance and claims her completely.
