Remi Mikage, 28 years old. A slut who is always completely lazy. That older sister is a pure gambler. Moreover, she is the type who believes in superstitions, always believing things without reason, such as "socks must always be put on from the right" or "natto must always be eaten for breakfast." One day, because of various things, I ejaculated, and the superstition that "if you fuck your younger brother, gambling will win" became popular among my older sister. That was the beginning of a dreamlike story where my older sister keeps fucking me.
