JUMP-5036 My little sister, Risa-chan, who is only about 140 cm tall, is still curious about naughty things and is always delusional.

Synopsis

Risa-chan, a girl who is still growing, is a pubertal girl who has expanded her breasts and is also interested in naughty things. I always bothered to ask my brother even if it was a naughty question, but the small dick that didn't even grow hair under it was developed by my brother and gradually remembered the pleasure. Here is the brother-sister love between Risa-chan and her older brother who loves her younger sister.
