I know which one you're talking about, but I can't for the life of me remember its name. The guy was assigned to investigate "strange things" (IE students getting massively horny), and the story goes from there. Couldn't play much, but it was good.

X-Change?
Dating sim, eroge, possibly visual novel.
One of the love interests is the protagonist's (older?) sister, who has blue hair (usually in a ponytail), a striped shirt, and possibly striped underwear. Think Akihisa's sister from Baka & Test, only athletic. Looks like an actual young adult (somewhere between 18 and 25), not the generic 14-year-old look many dating sims use regardless of character age.
99% sure it was on Windows, so it was either a Windows or an in-browser game.
May take place at a boarding school or a college (if so, some of it takes place in off-campus housing).
