I, a college student who lives in a rundown apartment in such a bad environment... One day when I was spending lazy days without dreams or hopes, Mr. Tsumugi moved into the next room. She is a beautiful woman with a bewitching atmosphere. That kind of girl used something to invite me... I can't even go against her sweet whispers that make my eardrums melt, and I'm drowning in nesting SEX with her married woman as she says.
