My Beloved Big Sister. A beautiful, 175cm tall woman with G-cup breasts has moved in next door to the apartment where I live alone. Hina- Hina is a warm-hearted college student with tall, big breasts who always looks after me, a younger man, but she's not very good at cooking or cleaning. In the end, I end up being treated like a convenient little brother and I'm at her mercy every day. I don't think she even notices me as a man, but as I'm in the midst of puberty, whenever I have naughty fantasies, she comes on to me with full knowledge... This is a collection of 4 stories about the temptations of my neighbor that are just too good to be true.
