Me That's Gotten Smaller, With The Admired Wife Marina Shiraishi

I drank some suspicious medicine bought online, and my body shrank! With this body, I can do pervy things adults can't, pretending to be a kid, doing whatever I want! I go play at the house of the admired wife next door, Mrs. Shiraishi, and we bathe together, nap together, and even insert!? Because I look cute, anything is forgiven!
