YSN-202 Onii-chan, you know... Seira Kazuki - Kazuki Seira

A younger sister who can only say "Onii-chan" when the two of them have a secret. The strange thing is that the word "oni-chan" not only conveys emotions, but also conveys the thoughts of the younger sister. She gave me a blowjob with a cute mouth and made me squid... I changed into my favorite school swimsuit and seduced her... In the bathroom, she washed my cock... My little sister only calls me "Onii-chan", but she's shy, but she's kind to me, and she always accepts everything about me in her body. And the secret between me and my sister continues all night long... A sister who gives herself over to pleasure and listens to what I say is the best girl.
