MDTM-016 Hot spring trip to make a baby with my sister who is 16 years younger 陽木かれん

Haruchan, my sister who overflows with transparency is 1● years old. Today is our first hot spring trip together. Haruchan is so cute that I can't stand it. 'I want a little sister' is her catchphrase, and when I said let's make one together, she was genuinely happy. For the purpose of creating a little sister, we did peeing, bit gag, barefaced irrumatio, hairless raw insemination. We promised to keep it a secret from mom, and she is truly a good girl.
