STARS-469 The overly meddlesome sister answers all of her little brother's problems with his foreskin penis Summeri Kousuke

"I want to wash my little brother's foreskin with bubbles." "I want to see how far my little brother's foreskin can stretch." "I want to measure the size of my little brother's penis." "I want to enhance my little brother's premature ejaculation." "I want to pop my little brother's cherry." These are the desires (things she wants to do) of Yume Akari, a sister who is extremely overprotective and has a complex about her younger brother (college graduate/OL). I'll do all of them. By the way, my little brother is a NEET.
