I’m looking for a doujin about a guy (I think he’s living in college) who gets a visit from his younger sister. She claims to have runaway, and asks to stay the night with him. To pay him back, she has sex with him in a variety of different outfits (bloomers, swimsuit, bunny girl outfit, etc.). I think the title is something along the lines of, “Being taken care of by my high school age sister,†but that’s just how I remember it from Reddit before it was removed and may be incorrect.
