HUNT-732 Six cute little sisters who aren't too popular and always worry about me as "history without her = age"! I miraculously made her! I thought my sisters would be happy, but the atmosphere was terrible.

I’ve never been able to do her since I was born, and even I, who isn’t popular at all, finally got her! When I invited her to my house with so much joy …, my six sisters glared at my girlfriend and made me feel strange. And from this day my sisters started to tempt me with naughty color schemes! And every day of incest! Is this the inside out of jealousy?
