Ane Taiken Shuukan 
I'm an older brother who loves to masturbate to my younger sisters and get scolded by them all the time for it, then I got a mail with a link and thought it's an eroge from a brand I love. I got an error and blackout when opening the file, nothing can be done and I go to sleep, the next morning when I woke up I found my body shrunk and let out a shout. My younger sisters now older sisters come and found me, Aya older sister who got a shota complex hugs and pampers me. 
Full lewd moments with my new older sisters, a one week "older sister experience".
