"I want to wash my little brother's foreskin penis with bubbles." "I want to see how far my little brother's foreskin penis can stretch." "I want to measure the size of my little brother's penis." "I want to enhance my little brother's premature ejaculation penis." "I want to deflower my little brother's virgin penis." These are the wishes (things she wants to do) of Yume Sumire, the overbearing sister (college graduate/OL) who is extremely doting on her younger brother. She will do all of them. By the way, her little brother is a NEET.
